## Background
The present application is a Continuation-In-Part of U.S. patent application Ser. No. 10/973,825, filed on Oct. 27, 2004, now abandoned which is hereby incorporated by reference.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a generator and a method of using a generator, and particularly, to a multivariable generator and method of using a multivariable generator.
2. Discussion of the Related Art
In general, electrical generators generally include a plurality of magnets arranged to have alternating magnetic field orientations (i.e., North and South) that pass by a plurality of coil windings to generate electrical energy. Specifically, as the magnets become aligned with the core structure of the coil windings, a magnetic field is induced to the core structure thereby generating a current in the coil windings. In addition, as each alternating magnetic field passes by the core structure, induction of the alternating magnetic fields generates significant amounts of heat within the core structure, thus limiting output efficiency of the electrical generator and reducing the lifespan of the electrical generator. For example, the significant amounts of heat generated by the electrical generator causes an under-efficiency of the output of the generator. Thus, preventing the generation of heat by the core structures may significantly improve the under-efficiency of the output of the electrical generator.
Moreover, the generation of heat by the electrical generator results in scheduled periodic maintenance, wherein the electrical generator must be taken off-line, disassembled, inspected, and rebuilt. Thus, the periodic maintenance is costly and time consuming. Accordingly, by designing an electrical generator that reduces, if not eliminates, the generation of heat by the core structures, an electrical generator having a high output efficiency may be achieved, thereby improving on-line generation of electrical output.
In general, coil members used in electrical generators include core portions formed of iron oxide materials. However, since operation of the electrical generators use alternating magnet fields induced in the core portions of the coil members, significant amounts of heat are produced. Accordingly, continuous use of the electrical generator produces large amounts of heat that requires using either internal cooling systems or bulky heatsinks to dissipate the heat. Thus, the physical size of the electrical generator is directly dependent upon the size and amount of heat it produces. Correspondingly, as the size of the electrical generator increases so does the system for dissipating the heat generated by the alternating magnetic fields induced in the core portions of the coil members of the electrical generator.
According to the related art, electrical generators are designed and built to provide single voltage/current outputs that are invariable. Accordingly, if more than one voltage/current output is required, then the electrical generator must be taken off-line and replaced with another electrical generator capable of producing the desired voltage/current output. Thus, valuable time and energy is required if multiple voltage/current outputs are desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
FIG. 1 is a schematic plan view of an exemplary electrical generator according to the present invention. In FIG. 1, a generator may include a rotor 100 and a pair of stators 200 each disposed on opposing sides of the rotor 100. Each of the rotors 100 and the stators 200 may be made from non-magnetic materials. Alternatively, the generator may include a single rotor 100 and one stator 200 disposed at only one side of the single rotor 100. In addition, the rotor 100 may be mechanically coupled to a rotating shaft 900 using at least one coupling member 1000 having a plurality of fastening members 1100.
In FIG. 1, the rotor 100 may include a plurality of magnetic source pairs 112a/112b, 122a/122b, and 132a/132b disposed through a thickness of the rotor 100. Accordingly, each of the magnet source pairs 112a/112b, 122a/122b, and 132a/132b may include opposing magnetic surfaces. For example, the first magnet source pair 112a/112b may have opposing magnetic orientations, wherein the first magnet source pair surface 112c may have one of North and South magnetic orientation and the first magnetic source pair surface 112d may have one of South and North magnetic orientation. Thus the first magnetic source pair surfaces 112c and 112d have opposing magnetic orientations.
In FIG. 1, each of the magnet source pairs 112a/112b, 122a/122b, and 132a/132b may be replaced with a single magnet source provided through the thickness of the rotor 100 at each of the locations of the magnet source pairs 112a/112b, 122a/122b, and 132a/132b. In addition, each of the magnet source pairs 112a/112b, 122a/122b, and 132a/132b, or the alternative single magnet sources may be either press-fit into the rotor 100, or may be mechanically retained in the rotor 100. Moreover, each of the magnet source pairs 112a/112b, 122a/122b, and 132a/132b, or the alternative single magnet sources may be bonded within the rotor 100.
In FIG. 1, the first magnetic source members 112a/112b may be disposed along a first radius of the rotor 100, the second magnetic source members 122a/122b may be disposed along a second radius of the rotor 100, and third magnetic source members 132a/132b may be disposed along a third radius of the rotor 100.
In FIG. 1, each of the stators 200 may include a first plurality of coil members 210 each disposed along a first radius of the stator 200, a second plurality of coil members 220 each disposed along a second radius of the stator 200, and a third plurality of coil members 230 each disposed along a third radius of the stator 200. For example, each of the stators 200 may include an “n”-number of the first, second, and third coil members 210, 220, and 230, whereas the rotor 100 may include an “n+1”-number of the magnetic source members 110. In other words, the rotor 100 may include an even number of magnetic sources 110, and each of the stators 200 may include an odd number of coil members 210.
Although not specifically shown, the rotor 100 may include an odd number of magnetic sources 110, and each of the stators 200 may include an even number of coil members 210. Accordingly, so long as the “cogging effect” is prevented, i.e., equal numbers of magnetic sources and coil members simultaneously aligned with each other, then the total numbers of magnetic sources and coil members may be varied depending on the desired voltage/current/frequency output.
As shown in FIG. 1, each of the coil members 210, 220, and 230 may include a coil winding portion disposed concentrically around a core portion. For example, as shown in FIG. 6, the coil member 210 may include a coil winding portion 212 disposed concentrically around a core portion 214. The core portion 214 may be disposed so as to have a first end portion extending past a first end region of the coil winding portion 230, and a second end portion extending to be flush with an interior surface 250 of the stator 200. In addition, the coil winding portion 212 may include a first end region extending into the stator 200, but offset from the interior surface 250 of the stator 200. Similarly, the coil winding portion 212 may extend past an exterior surface 260 of the stator 200. Accordingly, both the coil winding portion 212 and the core portion 214 may extend past the exterior surface 260 of the stator 200.
Accordingly, diamagnetic opposition to the coil winding portion 212 (in FIG. 6) of the coil member 210 may be prevented by offsetting the second end region of the coil winding portion 212 from the interior surface 250 of the stator 200. The stator 200 may further include a through-hole 240 to accommodate the rotating shaft 900 of the rotor 100. In addition, the through-hole 240 may be used for alignment of the rotating shaft 900 of the rotor 100.
In FIG. 1, each of the coil winding portions of each of the coil members 210, 220, and 230 of the stator 200 may include at least two conductive leads 216, 226, and 236 that may be electrically connected to a control system. Accordingly, the current induced to the coiling winding portions of each of the coil members 210, 220, and 230 may be fed to the control system for controlling an output of the generator. Although the coil winding portions of each of the coil members 210, 220, and 230 may include two conductive leads 216, 226, and 236, each of the coil winding portions of each of the coil members 210, 220, and 230 may include multiple “taps” having a plurality of conductive leads.
FIG. 2A is a schematic view of an exemplary rotor of a multivariable generator according to the present invention. In FIG. 2A, a generator rotor 100 may include the first plurality of magnetic sources 112 distributed to be equally spaced apart along the first radius 110 around the rotor 100. For example, each of the first plurality of magnetic sources 112 may have a diameter d1 and may be spaced apart from each other by a distance 2d1 between adjacent magnetic sources 112. Accordingly, each of the first plurality of magnetic sources 112 may be mutually spaced apart from each other by a distance equal to the diameter of the first magnetic sources 112, and the center of each of the first plurality of magnetic sources 112 may be disposed from the center C of the rotor 100 by a radius R1.
In FIG. 2A, the generator rotor 100 may include the second plurality of magnetic sources 122 distributed to be equally spaced apart along the second radius 120 around the rotor 100. For example, each of the second plurality of magnetic sources 122 may have a diameter d2 and may be spaced apart from each other by a distance 2d2 between adjacent magnetic sources 122. Accordingly, each of the second plurality of magnetic sources 122 may be mutually spaced apart from each other by a distance equal to the diameter of the second magnetic sources 122, and the center of each of the second plurality of magnetic sources 122 may be disposed from the center C of the rotor 100 by a radius R2.
In FIG. 2A, the generator rotor 100 may include the third plurality of magnetic sources 132 distributed to be equally spaced apart along the third radius 130 around the rotor 100. For example, each of the third plurality of magnetic sources 132 may have a diameter d3 and may be spaced apart from each other by a distance 2d3 between adjacent magnetic sources 132. Accordingly, each of the third plurality of magnetic sources 132 may be mutually spaced apart from each other by a distance equal to the diameter of the third magnetic sources 132, and the center of each of the third plurality of magnetic sources 132 may be disposed from the center C of the rotor 100 by a radius R3.
In FIG. 2A, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources. Furthermore, the coil winding portions of each of the first, second, and third coil members 210, 220, and 230 (in FIG. 1) may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 2A, each of the first, second, and third pluralities of magnetic sources 112, 122, and 132 are radially disposed to be mutually separated by an angle α of about 22.5 degrees (i.e., 360 degrees/16 magnet sources).
FIG. 2B is a schematic view of an exemplary stator of a multivariable generator corresponding to the exemplary rotor of FIG. 2A according to the present invention. In FIG. 2B, the stator 200 may include a first plurality of coil members 210 distributed to be equally spaced apart along a first radius R1 around the stator 200 similar to the distribution of the first plurality of magnetic sources 112 along the first radius R1 around the rotor 100 (in FIG. 2A). Accordingly, each of the first plurality of coil members 210 may be mutually spaced apart from each other by a distance corresponding to the center of each of the first plurality of magnetic sources 112.
In FIG. 2B, the stator 200 may include a second plurality of coil members 220 distributed to be equally spaced apart along a second radius R2 around the stator 200 similar to the distribution of the second plurality of magnetic sources 122 along the second radius R2 around the rotor 100 (in FIG. 2A). Accordingly, each of the second plurality of coil members 220 may be mutually spaced apart from each other by a distance corresponding to the center of each of the second plurality of magnetic sources 122.
In FIG. 2B, the stator 200 may include a third plurality of coil members 230 distributed to be equally spaced apart along a third radius R3 around the stator 200 similar to the distribution of the third plurality of magnetic sources 132 along the third radius R3 around the rotor 100 (in FIG. 2A). Accordingly, each of the third plurality of coil members 230 may be mutually spaced apart from each other by a distance corresponding to the center of each of the third plurality of magnetic sources 132.
In FIG. 2B, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources 112, 122, and 132 (in FIG. 2A). Furthermore, the coil winding portions of each of the first, second, and third coil members 210, 220, and 230 may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 2B, each of the first, second, and third pluralities of coil members 210, 220, and 320 are radially disposed to be mutually separated by an angle α of about 24.0 degrees (i.e., 360 degrees/15 coil members).
FIG. 3A is a schematic view of another exemplary rotor of a multivariable generator according to the present invention. In FIG. 3A, a generator rotor 300 may include the first plurality of magnetic sources 312 distributed to be equally spaced apart along the first radius 310 around the rotor 300. For example, each of the first plurality of magnetic sources 312 may have a diameter d1 and may be spaced apart from each other by a distance 2d1 between adjacent magnetic sources 312. Accordingly, each of the first plurality of magnetic sources 312 may be mutually spaced apart from each other by a distance equal to the diameter of the first magnetic sources 312, and the center of each of the first plurality of magnetic sources 312 may be disposed from the center C of the rotor 300 by a radius R1.
In FIG. 3A, the generator rotor 100 may include the second plurality of magnetic sources 322 distributed to be equally spaced apart along the second radius 320 around the rotor 300. For example, each of the second plurality of magnetic sources 322 may have a diameter d2 and may be spaced apart from each other by a distance 2d2 between adjacent magnetic sources 322. Accordingly, each of the second plurality of magnetic sources 322 may be mutually spaced apart from each other by a distance equal to the diameter of the second magnetic sources 322, and the center of each of the second plurality of magnetic sources 322 may be disposed from the center C of the rotor 300 by a radius R2.
In FIG. 3A, the generator rotor 300 may include the third plurality of magnetic sources 332 distributed to be equally spaced apart along the third radius 330 around the rotor 300. For example, each of the third plurality of magnetic sources 332 may have a diameter d3 and may be spaced apart from each other by a distance 2d3 between adjacent magnetic sources 332. Accordingly, each of the third plurality of magnetic sources 332 may be mutually spaced apart from each other by a distance equal to the diameter of the third magnetic sources 332, and the center of each of the third plurality of magnetic sources 332 may be disposed from the center C of the rotor 300 by a radius R3.
In FIG. 3A, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources. Furthermore, the coil winding portions of each of the first, second, and third coil members 210, 220, and 230 (in FIG. 1) may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 3A, each of the first, second, and third pluralities of magnetic sources 312, 322, and 332 are radially disposed to be mutually separated by an angle α of about 22.5 degrees (i.e., 360 degrees/16 magnet sources). In addition, the radial placement of the third plurality of magnetic sources 332 may be offset from the first and second pluralities of magnetic sources 312 and 322, by an angle β that may be between about 0 degrees and 22.5 degrees. Accordingly, different frequencies may be produced by the third plurality of magnetic source/coil members than the frequencies produced by the first and second pluralities of source/coil members.

In FIG. 3B, the stator 400 may include a third plurality of coil members 430 distributed to be equally spaced apart along a third radius R3 around the stator 400 similar to the distribution of the third plurality of magnetic sources 332 along the third radius R3 around the rotor 300 (in FIG. 3A).

In FIG. 3B, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources 312, 322, and 332 (in FIG. 3A). Furthermore, the coil winding portions of each of the first, second, and third coil members 410, 420, and 430 may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 3B, each of the first, second, and third pluralities of coil members 410, 420, and 420 are radially disposed to be mutually separated by an angle α of about 24.0 degrees (i.e., 360 degrees/15 coil members). In addition, the radial placement of the third plurality of coil members 430 may be offset from the first and second pluralities of coil members 410 and 420, by an angle β that may be between about 0 degrees and 24.0 degrees. Accordingly, different frequencies may be produced by the third plurality of coil members/magnetic sources than the frequencies produced by the first and second pluralities of coil members/magnetic sources.

In FIG. 4A, a generator rotor 500 may include the first plurality of magnetic sources 512 distributed to be equally spaced apart along the first radius 510 around the rotor 500. For example, each of the first plurality of magnetic sources 512 may have a diameter d1 and may be spaced apart from each other by a distance 2d1 between adjacent magnetic sources 512. Accordingly, each of the first plurality of magnetic sources 512 may be mutually spaced apart from each other by a distance equal to the diameter of the first magnetic sources 512, and the center of each of the first plurality of magnetic sources 512 may be disposed from the center C of the rotor 500 by a radius R1.
In FIG. 4A, the generator rotor 500 may include the second plurality of magnetic sources 522 distributed to be equally spaced apart along the second radius 520 around the rotor 500. For example, each of the second plurality of magnetic sources 522 may have a diameter d2 and may be spaced apart from each other by a distance 2d2 between adjacent magnetic sources 522. Accordingly, each of the second plurality of magnetic sources 522 may be mutually spaced apart from each other by a distance equal to the diameter of the second magnetic sources 522, and the center of each of the second plurality of magnetic sources 522 may be disposed from the center C of the rotor 500 by a radius R2.
In FIG. 4A, the generator rotor 500 may include the third plurality of magnetic sources 532 distributed to be equally spaced apart along the third radius 530 around the rotor 500. For example, each of the third plurality of magnetic sources 532 may have a diameter d3 and may be spaced apart from each other by a distance 2d3 between adjacent magnetic sources 532. Accordingly, each of the third plurality of magnetic sources 532 may be mutually spaced apart from each other by a distance equal to the diameter of the third magnetic sources 532, and the center of each of the third plurality of magnetic sources 532 may be disposed from the center C of the rotor 500 by a radius R3.
In FIG. 4A, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources. Furthermore, the coil winding portions of each of the first, second, and third coil members 210, 220, and 230 (in FIG. 1) may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 4A, each of the first, second, and third pluralities of magnetic sources 512, 522, and 532 are radially disposed to be mutually separated by an angle α of about 22.5 degrees (i.e., 360 degrees/16 magnet sources). In addition, the radial placement of the second plurality of magnetic sources 522 may be offset from the first and third pluralities of magnetic sources 512 and 532, by an angle β that may be between about 0 degrees and 22.5 degrees. Accordingly, different frequencies may be produced by the second plurality of magnetic source/coil members than the frequencies produced by the first and third pluralities of source/coil members.
FIG. 4B is a schematic view of another exemplary stator of a multivariable generator corresponding to the exemplary rotor of FIG. 4A according to the present invention.

Accordingly, each of the first plurality of coil members 610 may be mutually spaced apart from each other by a distance corresponding to the center of each of the first plurality of magnetic sources 512.
In FIG. 4B, the stator 600 may include a second plurality of coil members 620 distributed to be equally spaced apart along a second radius R2 around the stator 600 similar to the distribution of the second plurality of magnetic sources 522 along the second radius R2 around the rotor 500 (in FIG. 4A). Accordingly, each of the second plurality of coil members 620 may be mutually spaced apart from each other by a distance corresponding to the center of each of the second plurality of magnetic sources 522.
In FIG. 4B, the stator 600 may include a third plurality of coil members 630 distributed to be equally spaced apart along a third radius R3 around the stator 600 similar to the distribution of the third plurality of magnetic sources 532 along the third radius R3 around the rotor 500 (in FIG. 4A). Accordingly, each of the third plurality of coil members 630 may be mutually spaced apart from each other by a distance corresponding to the center of each of the third plurality of magnetic sources 532.
In FIG. 4B, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources 512, 522, and 532 (in FIG. 4A). Furthermore, the coil winding portions of each of the first, second, and third coil members 610, 620, and 630 may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 4B, each of the first, second, and third pluralities of coil members 610, 620, and 630 are radially disposed to be mutually separated by an angle α of about 24.0 degrees (i.e., 360 degrees/15 coil members). In addition, the radial placement of the second plurality of coil members 620 may be offset from the first and third pluralities of coil members 610 and 630, by an angle β that may be between about 0 degrees and 24.0 degrees. Accordingly, different frequencies may be produced by the second plurality of coil members/magnetic sources than the frequencies produced by the first and third pluralities of coil members/magnetic sources.
FIG. 5A is a schematic view of another exemplary rotor of a multivariable generator according to the present invention. In FIG. 5A, a generator rotor 700 may include the first plurality of magnetic sources 712 distributed to be equally spaced apart along the first radius 710 around the rotor 700. For example, each of the first plurality of magnetic sources 712 may have a diameter d1 and may be spaced apart from each other by a distance 2d1 between adjacent magnetic sources 712. Accordingly, each of the first plurality of magnetic sources 712 may be mutually spaced apart from each other by a distance equal to the diameter of the first magnetic sources 712, and the center of each of the first plurality of magnetic sources 712 may be disposed from the center C of the rotor 700 by a radius R1.
In FIG. 5A, the generator rotor 700 may include the second plurality of magnetic sources 722 distributed to be equally spaced apart along the second radius 720 around the rotor 700. For example, each of the second plurality of magnetic sources 722 may have a diameter d2 and may be spaced apart from each other by a distance 2d2 between adjacent magnetic sources 722. Accordingly, each of the second plurality of magnetic sources 722 may be mutually spaced apart from each other by a distance equal to the diameter of the second magnetic sources 722, and the center of each of the second plurality of magnetic sources 722 may be disposed from the center C of the rotor 700 by a radius R2.
In FIG. 5A, the generator rotor 700 may include the third plurality of magnetic sources 732 distributed to be equally spaced apart along the third radius 730 around the rotor 700. For example, each of the third plurality of magnetic sources 732 may have a diameter d3 and may be spaced apart from each other by a distance 2d3 between adjacent magnetic sources 732. Accordingly, each of the third plurality of magnetic sources 732 may be mutually spaced apart from each other by a distance equal to the diameter of the third magnetic sources 732, and the center of each of the third plurality of magnetic sources 732 may be disposed from the center C of the rotor 700 by a radius R3.
In FIG. 5A, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources. Furthermore, the coil winding portions of each of the first, second, and third coil members 210, 220, and 230 (in FIG. 1) may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 5A, each of the first, second, and third pluralities of magnetic sources 712, 722, and 732 are radially disposed to be mutually separated by an angle α of about 22.5 degrees (i.e., 360 degrees/16 magnet sources). In addition, the radial placement of the first plurality of magnetic sources 712 may be offset from the second and third pluralities of magnetic sources 722 and 732, by an angle β that may be between about 0 degrees and 22.5 degrees. Accordingly, different frequencies may be produced by the first plurality of magnetic source/coil members than the frequencies produced by the second and third pluralities of source/coil members.
FIG. 5B is a schematic view of another exemplary stator of a multivariable generator corresponding to the exemplary rotor of FIG. 5A according to the present invention. In FIG. 5B, the stator 800 may include a first plurality of coil members 810 distributed to be equally spaced apart along a first radius R1 around the stator 800 similar to the distribution of the first plurality of magnetic sources 712 along the first radius R1 around the rotor 700 (in FIG. 5A). Accordingly, each of the first plurality of coil members 810 may be mutually spaced apart from each other by a distance corresponding to the center of each of the first plurality of magnetic sources 712.
In FIG. 5B, the stator 800 may include a second plurality of coil members 820 distributed to be equally spaced apart along a second radius R2 around the stator 800 similar to the distribution of the second plurality of magnetic sources 722 along the second radius R2 around the rotor 700 (in FIG. 5A). Accordingly, each of the second plurality of coil members 820 may be mutually spaced apart from each other by a distance corresponding to the center of each of the second plurality of magnetic sources 722.
In FIG. 5B, the stator 800 may include a third plurality of coil members 830 distributed to be equally spaced apart along a third radius R3 around the stator 800 similar to the distribution of the third plurality of magnetic sources 732 along the third radius R3 around the rotor 700 (in FIG. 5A). Accordingly, each of the third plurality of coil members 830 may be mutually spaced apart from each other by a distance corresponding to the center of each of the third plurality of magnetic sources 732.
In FIG. 5B, spacings between each of the first, second, and third radii R1, R2, and R3 may be determined by each of the diameters d1, d2, and d3 of the first, second, and third pluralities of magnetic sources 712, 722, and 732 (in FIG. 5A). Furthermore, the coil winding portions of each of the first, second, and third coil members 810, 820, and 830 may determine the spacings between each of the first, second, and third radii R1, R2, and R3. Accordingly, the spacings between each of the first, second, and third radii R1, R2, and R3 may be scaled up or scaled down based upon an overall physical size of the electrical generator.
In FIG. 5B, each of the first, second, and third pluralities of coil members 810, 820, and 830 are radially disposed to be mutually separated by an angle α of about 24.0 degrees (i.e., 360 degrees/15 coil members). In addition, the radial placement of the first plurality of coil members 810 may be offset from the second and third pluralities of coil members 820 and 830, by an angle β that may be between about 0 degrees and 24.0 degrees. Accordingly, different frequencies may be produced by the first plurality of coil members/magnetic sources than the frequencies produced by the second and third pluralities of coil members/magnetic sources.
In each of FIGS. 2A-5B, various combinations of offsets may be used. Specifically, in order to accommodate large diameter magnet sources/coil members, the offset angles β may be varied in order to provide desired electrical outputs from the coil members. Moreover, multiple offset angles β may be incorporated in the rotor and stators to provide an electrical generator capable of producing specific relative outputs.
According to the present invention, each of the rotors and stator pairs may have diameters larger than those shown in FIGS. 2A-5B. For example, if each of the rotors and stator pairs where to include more than three concentric rings of magnetic sources and coil members, then the diameters of the rotors and stator pairs would increase proportionally. Accordingly, diameters of the rotors and stator pairs may be ultimately as large as a house, for example, or even larger. Thus, the exemplary rotor and stator pairs shown in FIGS. 2A-5B are not to be considered limiting with respect to the present invention, but merely demonstrate basic exemplary configurations for the rotor and stator pairs.
FIG. 6 is an enlarged view of section A of FIG. 1 showing a schematic view of an exemplary coil member of an electrical generator according to the present invention. In FIG. 6, a coil member 210 may be embedded within the stator 200. The coil member 210 may include the coil winding portion 212 and the core portion 214, wherein the coil winding portion 212 may extend from the exterior surface 260 of the stator 200 by a distance X1, and the core portion may extend from the exterior surface 260 of the stator 200 by a distance X4 and may extend from the end portion of the coil winding portion 212 by a distance X3. In addition, another end portion of the coil winding portion 212 may be offset from the interior surface 250 of the stator 200 by a distance X2. Of course, each of the distances X1, X2, X3, and X4 may be varied based upon the desired output from the electrical generator. Specifically, in order to minimize electrical/magnetic interference between adjacent coil members and/or adjacent magnetic sources, any of the distances X1, X2, X3, and X4 may be varied.
As shown in FIG. 6, an outermost diameter Y1 of the coil winding portion 212 may be slightly less than a hole having a diameter Y2. Accordingly, the diameter Y2 of the hole in the stator 200 may be varied depending upon the outermost diameter Y1 of the coil winding portion 212, or may be varied depending upon neighboring coil members disposed along the first radius R1 (in FIGS. 2B, 3B, 4B, and 5B) or upon neighboring coil members disposed along the second or third radii R2 and R3 (in FIGS. 2B, 3B, 4B, and 5B). Furthermore, the diameter Y2 may be dependent upon the diameter d1 of the core portion 214 and/or the number of coil windings and wire diameter of the coil winding portion 212.
In FIG. 6, the core portion 214 may be formed of amorphous or microcrystalline material in order to reduce/eliminate the heat produced by the alternating magnet field induced to the core portion of the coil member. For example, Manganese Zinc (MnZn) Ferrite powder (about 400 mesh) may be molded into the required shape of the core portion of the coil member. Then, the molded manganese zinc ferrite material may be sintered into a solid core structure. Accordingly, the sintered core structure may be wound with wire along a portion of the length of the sintered core structure. For example, as shown in FIG. 6, the coil winding portion 212 may be offset from end portions of the core portion 214.
The manganese zinc ferrite powder used to form the core portion 214 may comprise about 10% to about 90% Iron, Manganese, and Zinc. Accordingly, the core portion 214 may be produced having a 50 kHz rating, such that the core may not produce any heat operating at a frequency of about 400 Hz and about 800 Hz. Furthermore, since the MnZn Ferrite material used to form the core portion 214 has a relatively high permeability, the magnetic field may be easily induced to the core portion 214. Similarly, as the magnetic field is withdrawn from the core portion 214, the induced magnetic field within the core portion 214 is easily diminished. Thus, the MnZn Ferrite material does not exhibit any appreciable remnant magnetic polarization.
FIG. 7 is a schematic view of an exemplary assembled electrical generator according to the present invention. In FIG. 7, assembly of an electrical generator may include positioning both of the stators 200 to sandwich the rotor 100 with a relatively small distance between each. For example, positioning of the stators 200 with the rotor 100 may be accomplished so as to provide a distance within a range of a few thousandths of an inch or larger between the respective faces of the core portions 214, 224, and 234 (in FIG. 2B) and the magnetic sources 112, 122, and 132 (in FIG. 2A). Thus, the distance between the faces of the core portions 214, 224, and 234 and the magnetic sources 112, 122, and 132 may be adjusted by use of adjusting fasteners 1200 and 1210 that may be distributed along the outermost circumference of the stators 200 and extend through the stators 200. In addition, a double fastener pair 1400 and 1412 may used in conjunction with the adjusting fasteners 1200 and 1210 to provide a positively locked assembly.
In FIG. 7, the double fastener pair 1400 and 1412 may be provided to mechanically affix the stators 200 to a base member 1330 using a plurality of base fastener pairs 1320 and 1340. Each of the double fastener pairs 1400 and 1412 may extend through holes at an upper portion 1312 of a frame member 1310 into a portion of the stators 200 to be fastened to a stator fastener 1412 provided at the interior surface 250 (in FIG. 1) of the stator 200. Accordingly, a lower portion 1314 of the frame member 1310 may be affixed to the base member 1330 using the plurality of the base fastener pairs 1320 and 1340.

Accordingly, the terminal block 12 includes an output connection connected between the center wire portion 1A of the first coil member 1 and the outer wire portion 3B of the third coil member 3 in order to produce OUTPUT 1.
In FIG. 9, second, third, fourth, and fifth terminal blocks 22, 32, 42, and 52 are provided in order to channel/route the center and outer wire portions of the coil members. Specifically, the second terminal block 22 routes the center and outer wire portions 4A/4B, 5A/5B, and 6A/6B of the fourth, fifth, and sixth coil members 4, 5, and 6 in order to produce OUTPUT 2. Similarly, the third terminal block 32 routes the center and outer wire portions 7A/7B, 8A/8B, and 9A/9B of the seventh, eighth, and ninth coil members 7, 8, and 9 in order to produce OUTPUT 3. Likewise, the fourth terminal block 42 routes the center and outer wire portions 10A/10B, 11A/11B, and 12A/12B of the tenth, eleventh, and twelfth coil members 10, 11, and 12 in order to produce OUTPUT 4. Finally, the fifth terminal block 52 routes the center and outer wire portions 13A/13B, 14A/14B, and 15A/15B of the thirteenth, fourteenth, and fifteenth coil members 13, 14, and 15 in order to produce OUTPUT 5.
In FIG. 9, each of the outputs OUTPUT 1, 2, 3, 4, and 5 may be further conditioned or modified in order to provide voltage a current. In addition, each of the outputs OUTPUT 1, 2, 3, 4, and 5 may be applied to individual or groups of electrical loads.
In FIG. 10, a 6-phase output configuration may be used, wherein groups of five adjacent coil members 1-5 may be electrically interconnected to provide a single output 1. Specifically, a first terminal block 14 may include a first connection receiving the center wire portion 1A of the first coil member 1, a second connection receiving the outer wire portions 1B and 2B of the first and second coil members 1 and 2, a third connection receiving the center wire portions 2A and 3A of the second and third coil members 2 and 3, a fourth connection receiving the outer wire portions 3B and 4B of the third and fourth coil members 3 and 4, a fifth connection receiving the center wire portions 4A and 5A of the fourth and fifth coil members 4 and 5, and a sixth connection receiving the outer wire portion of the fifth coil member 5. Accordingly, the terminal block 14 includes an output connection connected between the center wire portion 1A of the first coil member 1 and the outer wire portion 3B of the fifth coil member 5 in order to produce OUTPUT 1.
In FIG. 10, second and third terminal blocks 24 and 34 are provided in order to channel/route the center and outer wire portions of the coil members.

Similarly, the third terminal block 34 routes the center and outer wire portions 11A/11B, 12A/12B, 13A/13B, 14A/14B, and 15A/15B of the eleventh, twelfth, thirteenth, fourteenth, and fifteenth coil members 11-15 in order to produce OUTPUT 3.
FIG. 11 is a schematic view of an exemplary method of generating electrical energy according to the present invention. In FIG. 11, a method of generating electrical energy may involve rotation of a rotor 100 (in FIG. 1), for example, between adjacent stators 200 (in FIG. 1). Accordingly, as the rotor 100 rotates, the magnetic sources 112 pass by second end portions 224 of cores 214. However, as the rotor 100 rotates, only a single magnetic source 112 is aligned with any one of the second portion 224 of a core 214. Thus, as the rotor 100 rotates, the magnetic sources 112 become aligned with corresponding cores 214. For example, as the magnetic source 112 is aligned with the second end portion 224 of the core 214, at an upper portion of the rotor 100, then another magnetic source 112 at a lower portion of the rotor 100 may be positioned between adjacent coiling members 210. When the magnetic source 112 is aligned with the second end portion 224 of the core 214, at the upper portion of the rotor 100, then the magnetic source 112 imparts a magnetic moment to core 214 that is equal to the N/S/polarity of the magnetic source 112. Then, a current is induced to the coiling winding portion 212 of the coil member 210, and an electrical output is produced and transmitted along conductive leads (not shown) of the coil winding portion 212. Then, the electrical output is transmitted to a controller (not shown) for further processing.
Similarly, as shown in FIG. 11, at side portions of the rotor 100, magnetic sources 112 may be coming into and out of alignment with corresponding coil members 210. Therefore, as the rotor 100 rotates, electrical energy may be sequentially produced by the coil members 210. In addition, since rotation of the rotor 100 may be varied, then the electrical energy produced by the coil members 210 may be varied. For example, frequency, voltage, and amperage of the electrical energy may be varied. Furthermore, the controller (not shown) may further vary the electrical energy produced by the coil members 210.
FIG. 12 is a schematic view of an exemplary electrical generator providing multiple variable voltage/current outputs. In FIG. 12, a plurality G1, G2, . . . Gn of the exemplary electrical generator, as shown in FIG. 7, may be provided along a common base 1330. Accordingly, a common rotating shaft 900 may mechanically couple each of the rotors 100 to rotate at a common speed. Alternatively, the rotating shaft 900 may comprise a plurality of half-shafts in order to facilitate interchanging of the rotors 100 and stators 200 without disturbing adjacent ones of the plurality of electrical generators G1, G2, . . . Gn. Thus, the configuration of the plurality of electrical generators G1, G2, . . . Gn may allow for each of the plurality of electrical generators G1, G2, . . . Gn to produce different voltage, current, and/or frequency outputs by rotation of the rotating shaft 900. In either case, each of the plurality of electrical generators G1, G2, . . . Gn may individually be reconfigurable by interchanging the rotors 100 and corresponding stator pairs 200.
It will be apparent to those skilled in the art that various modifications and variations can be made in the multivariable generator and method using a multivariable generator of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
