## Background
FIELD OF THE INVENTION
The present invention generally relates to a combined electric motor and generator configuration, which returns electrical energy usable for driving the motor.
The present invention particularly relates to an efficient and powerful motor containing a generator section by utilizing a substantially similar configuration for the generator section.
BACKGROUND OF THE INVENTION
Reactive devices of electrical circuits, i.e. inductance and capacitance, are known to store energy. A regenerative motor that produces electrical energy, which is fed back to the motor, is a mechanical equivalent reactive device storing energy mechanically.
Motors, which are energy conversion devices, can convert in either direction. When a motor is combined with a generator, the electrical voltage output of the generator is sourced by the power amplifier and reduces the amount of electric power needed to drive the motor. Instead of inputting electrical energy, it proceeds to source it instead, drawing from its mechanical supply. The measurable result is a winding-induced efficient regeneration is a capability for a new age in motor-drive design.
As environmental protection considerations are becoming an imperative concern on the world agenda, the benefit of regenerative motor control is becoming increasingly evident and a driving force for development of this breed of motors.

Szkloa, Roberto Schaeffera and Michael A. McNeilb, “Energy-efficiency standards for electric motors in Brazilian industry”, Energy Policy, Volume 35, Issue 6, June 2007, Pages 3424-3439).
The present invention utilizes movable packed arrays of matching magnetic pairs having magnetic fields between them and matching stationary packed arrays disposed between the matching magnetic pairs. Tilted magnetic field of each pair and matching tilted electromagnetic coils are used for the motor section of the motor generator. Perpendicular magnetic fields between each matching magnetic pairs and matching perpendicular electromagnetic coils are used for the generator section of the motor. Thus an integrated motor-generator device can be put together effortlessly. The configuration concept accommodates an efficient and high power density motor. Likewise, the configuration concept accommodates an efficient and high power density generator. The integrated motor-generator device enhances efficiency substantially further.
Reference is now made to FIG. 1, a block diagram of an integrated motor-generator system. Integrated motor-generator 10 has a unique configuration adapted in a first section for operating as a motor and adapted in a second section for operating as a generator by accommodating insignificant changes to the basic configuration. The motor input voltage 14 is connected to electromagnetic coils in the motor section for rotating the motor rotor. Similar electromagnetic coils, which are differently oriented, in the generator section, generate electrical voltage output 11. The output voltage 11 is fed back into the power amplifier 12 which is also connected to input voltage 13. Power amplifier 12 matches the phase of input voltage 13 and generator output voltage 11 accommodating lesser electrical power use by subtracting fed back voltage 11 from input voltage 13 and consequently increasing motor efficiency.
Reference is now made to FIG. 2 a non-dimensionally scaled cross sectional view of a motor-generator embodiment. A cylindrically shaped motor-generator rotates around shaft 22 disposed at the cylindrical symmetry axis. Disks 23a, 23b and 23c affixed to motor shaft 22 are the infrastructure of the motor-generator rotor. An array of magnets is affixed to the bottom surface of disk 23a. Likewise, an array of magnets is affixed to the top surface of disk 23b. The magnets arrays of these adjacent surfaces are arranged in matching pairs (matching magnetic pairs) facing each other. Likewise, magnets array pairs facing each other are affixed to the bottom surface of disk 23b and to the top surface of disk 23c. Coil support structures 24a and 24b are the infrastructure of the motor-generator stator. Coil support structure 24a sustains a plurality of electromagnetic coils between each matching magnetic pairs affixed to disks 23a and 23b. Likewise, coil support structure 24b sustains a plurality of coils between each matching magnetic pairs affixed to disks 23b and 23c. Magnetic fields of matching magnetic pairs and corresponding coils disposed in peripheral section 20a and 20b are equally tilted. A voltage applied to the coils in this section generates a magnetic field tilted axially. The interaction between the magnetic fields of the coils and magnetic fields of the matching magnetic pairs creates a force vector in the same direction having components exerting a rotational moment on the rotor. Thus this section is the motor section of the device. Magnetic fields of matching magnetic pairs and corresponding coils disposed in the central section 21a and 21b are vertically disposed. When the rotor is rotating, the perpendicular magnetic fields between the matching magnetic pairs introduce a time varying magnetic flux through the perpendicular coils generating a voltage in the coils. The perpendicular coils are connected to the voltage output of the generator section. Thus the motor configuration is turned into a generator by using perpendicular arrangement rather than tilted arrangement.
In the above embodiment the motor includes three disks with four magnetic array surfaces, in a non-limiting manner. Nonetheless, any practical number of disks used is within the scope of the invention.
The tilt angle, which can have any value between greater than 0° up to 180° in any direction with respect to the main longitudinal axis of the disk, may differ on various locations within the motor-generator volume, for optimizing motor operation and efficiency.
The magnets may have a polygon or circular shape and is either a magnetic field source, commonly fabricated from a rare earth material as samarium, neodymium or a part made of iron. The structure is packaged within an ironed wall package with low magnetic losses, which are used to close the magnetic field lines while minimizing losses.
The disks are made of magnetic materials contacting the iron made motor shaft and iron made motor enclosure for providing low magnetic resistance path to the magnetic field of each pair. Air gaps between coils and corresponding matching magnetic pairs of the arrangement are minimized for minimizing magnetic field losses through them.
High magnetic flux density created by a plurality of matching magnetic pairs, a dense structure of matching magnetic pairs and matching generator coils, minimal size of air gaps between the coils and the magnets minimizing magnetic field losses, are adaptable in this invention for providing high efficiency and high-density electrical motor-generator.
Winding of electromagnetic coils can be made in two opposite directions creating opposite magnetic field directions and consequently opposite force vectors. In one embodiment the array of coils may include reversibly wound coils arranged in the array and used for optimizing motor-generator efficiency.
Reference is now made to FIG. 3, a top view of a motor generator disk depicting the motor and generator sections. Peripheral motor section 30 extending from the disk edge inwardly. The generator is included the smaller central section 31 of the disk. The rotational moment applied on the rotor is highest at the disk edge. For that reason the external section of the rotary disks is used for the motor and the central internal section of the disk is used for configuring the generator.
Reference is now made to FIG. 4, a cross sectional view of a fraction of two adjacent disks having pairs of magnets facing each other affixed to them. The matching magnetic pairs are displaced in the motor section to form a tilted magnetic field and are non-displaced in the generator section to form perpendicular magnetic fields between them.
At the generator section, magnet 45a affixed to disk 40a and magnet 45b affixed to disk 40b, are a pair of permanent field sources. Permanent magnetic source 45b has a north magnetic pole facing upward and permanent magnetic source 45a has a south magnetic pole facing downward. Consequently, the magnetic field between this pair creates a perpendicular attraction force.
At the generator section too, magnet 44a and magnet 44b are permanent magnets with their common north poles. Consequently, the magnetic field between this pair creates a perpendicular repelling force.
At the motor section magnet 43a is an iron part and magnet 43b is a permanent magnetic field source of any pole direction. A tilted magnetic field is generated between this pair of magnets by the iron part 43a being magnetized by the permanent magnetic field source 43b. 
At the motor section magnet 42a is a permanent magnetic field source and magnet 42b is a part of iron. Thus this pair of magnets is arranged opposite to the pair of magnets 43a and 43b and has a tilted magnetic field as well.
At the motor section, the magnetic field of an electromagnetic coil disposed between the matching magnetic pairs and applied with an electrical voltage, interact with the tilted magnetic field of the pair. The offset between pairs of magnets does not coincide with a disk radial line. Consequently, the interaction between the magnetic field of the matching magnetic pairs and the magnetic field of the related coil creates a force vector having a tangential component on the disk exerting a rotational moment on the motor rotor.
At the generator section, when the rotor is rotating time varying perpendicular magnetic flux is applied to the perpendicular coils and generates an electrical voltage in each of the generator coils.
Reference is now made to FIG. 5a, which is a top view of a disk of the motor showing an embodiment of magnets' arrangement on motor-generator disk 50. A array of magnets can be arranged staggered along adjacent radial lines on the disk. For example, the line of roundly shaped magnets 51 are arranged along a radial line and an adjacent line of magnets are staggered with respect to radial line 51. Likewise, a line of hex shaped magnets 56 can be arranged along a radial line. Adjacent hex shaped radial lines do not have to be staggered by fitting well side by side on adjacent radial lines.
The disk is made of magnetic material for providing low magnetic field resistance. The disk surface is coated with a non-magnetic material for accommodating magnetic field isolation between the magnets. The magnetic disk contacts the iron made shaft and motor enclosure for providing low magnetic field resistance to the matching magnetic pairs.
Reference is now made to FIG. 5b, which is a top view of a disk showing a magnets arrangement on motor-generator disk 50. An array of magnets can be arranged along radial lines on the disk. For example, the line of roundly shaped magnets 52 are arranged along a radial line. The magnets arranged along a radial line have a gradual size increase. This allows an easier arrangement of magnets along adjacent radial lines.
The disk is made of magnetic material for providing low magnetic field resistance to the magnetic field of the matching magnetic pairs. The disk surface is coated with a non-magnetic material for accommodating magnetic isolation between the magnets. The magnetic disk contacts the iron made motor enclosure for providing low magnetic field resistance to the matching magnetic pairs.
Reference is now made to FIG. 5c, showing another magnets arrangement on motor-generator disk 50. An array of magnets is arranged along a curved line from the disk center to the disk edge, rather than along a straight radial line, as in the preceding figures.
The disk is made of magnetic material for providing low magnetic field resistance to the magnetic field of the magnets. The disk surface is coated with a non-magnetic material for accommodating magnetic isolation between the magnets. The magnetic disk contacts the iron made motor enclosure for providing low magnetic field resistance to the matching magnetic pairs.
Reference is now made to FIG. 5d, which is a top view of a disk embodiment showing another magnets arrangement on motor disk 50. An array of magnets is arranged along a spiral 55 starting at the disk center and extending all the way to the disk edge.
The disk is made of magnetic material for providing low magnetic field resistance to the magnetic field of the magnets. The disk surface is coated with a non-magnetic material for accommodating magnetic isolation between the magnets. The magnetic disk contacts the iron made motor enclosure for providing low magnetic field resistance to the matching magnetic pairs.
The magnets arrangement embodiment within the scope of the invention may include a plurality device sizes and shapes, which can be arranged differently as arrays of magnets.
The tilt angle of the magnetic field of magnet pairs can be of different angle and direction with respect to the main longitudinal axis of the disk.
