Title: Magnetism driven power machine

Description:
BACKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] The present invention relates to a power machine, more particularly a power machine, which includes a rotor equipped with magnets, and a stator also equipped with magnets so that rotational movement of the rotor can be produced with the attraction and repulsion of the magnets.  
       [0003] 2. Brief Description of the Prior Art  
       [0004] While electricity has been the most common source in powering a motor, which is provided for passing on the rotation of the rotor affected by electricity to other machinery, man is still searching for new and inexpensive sources of producing electricity. Wind power has long been used as one such source. Electricity is provided to a motor so that a magnetic field is formed for effecting rotation of the shaft. It is also a main task to provide increased power output with certain amount of electricity, or certain amount of power output with decreased consumption of electricity for a motor. It is another task to provide a power machine that has power output capable of being adjusted to fit various circumstances. Because magnets have the advantages of having magnetic force that is continual and not prone to decrease, they are taken into consideration in searching for inexpensive substitutes for electricity.  
       SUMMARY OF THE INVENTION  
       [0005] It is a main object of the present invention to provide a magnetism driven power machine, which includes a rotor equipped with magnets, and a stator also equipped with magnets so that rotation of the rotor can be effected by means of the attraction and repulsion of the magnets.  
       [0006] It is another object of the present invention to provide a magnetism driven power machine, of which power output can be adjusted to fit various circumstances.  
       [0007] The present magnetism driven power machine includes a main body, a rotating rack, rotors, and stators. The main body is cylindrical. The rotating rack can rotate about the central axis of the main body, and has two opposing disks connected to the shaft thereof. Each of the rotors has a bent bar connected to inner sides of the disks at two ends, and has magnets spaced along the bent bar. Each of the stators has C-shaped magnets spaced along respective one of rods equidistantly positioned along the outer side of the cylindrical wall. Thus, attraction and repulsion of the magnets and corresponding C-shaped magnets make rotation of the rotating rack continue. Adjustment member is provided for displacing the C-shaped magnets relative to corresponding magnets to adjust power output of the present machine.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0016] Referring to FIGS. 1, 2 and  3 , a magnetism driven power machine of the present invention includes a main body  1 , a rotating rack  2 , a rotor set  3 , a stator set  4 , and an adjustment member  5 .  
     [0017] The main body  1  has a cylindrical outer wall, and end covers  13  fitted to two ends of the cylindrical wall. Straight guiding protrusions  11  are equidistantly formed along an outer side of the cylindrical wall of the main body  1  to be parallel with the axis of the main body  1 .  
     [0018] The rotating rack  2  has a shaft  21 , and two disk-shaped portions  22 . The shaft  21  is positioned along the central axis of the main body  1  with two ends thereof sticking out from the end covers  13  of the main body  1  so that the rotating rack  2  can be turned in the main body  1 . The disk-shaped portions  22  are connected to the shaft  21  at centers thereof In addition, the disk-shaped portions  22  have wheels  221  fitted to outward sides thereof to come into contact with an inner side of the cylindrical wall of the main body  1 .  
     [0019] The rotor set  3  includes several rotor elements, each of which has a connecting bar  31 , and several magnets  32  equidistantly spaced along the connecting bars  31 . The connecting bars  31  are turned around a central point and bent to a certain shape, and are connected to inner sides of the disk-shaped portions  22  at a first end and a second end; the first ends and the second ends of the bars  31  are preferably spaced around the centers of the corresponding disk-shaped portions  22 . The magnets  32  are arranged such that flat sides thereof face outwards, and lines normal to the flat sides form a radial pattern.  
     [0020] The stator set  4  includes several stator elements, each of which has a guiding rod  41 , and several C-shaped magnets  42  equidistantly spaced along the guiding rods  41 . Each of the guiding rods  41  has a guiding trench  411  lengthwise formed thereon. The guiding rods  41  are movably fitted on the cylindrical wall of the main body  1  with the guiding trenches  411  being fitted onto a respective one of the straight guiding protrusions  11  of the main body  1 . The C-shaped magnets  42  are arranged such that openings thereof face the outer side of the cylindrical wall of the main body  1 . The guiding rods  41  further stick through an inner section of a first one of the end covers  13  of the main body  1  at a first end for connection with the adjustment member  5 . And, each of the first ends of the guiding rods  41  is equipped with a pin  412  that is positioned perpendicular thereto. A housing member  12  is joined to the main body  1  to protect the stator set  4 .  
     [0021] Referring to FIGS. 4, 5 and  6 , the adjustment member  5  includes an exterior adjusting ring  51 , an interior adjusting ring  52 , an adjustment knob  53 , and a gear wheel  531 . The adjustment knob  53  is fitted to the first end cover  13 , and joined to the gear wheel  531 , which is disposed in an annular compartment of the first end cover  13 . The exterior adjusting ring  51 , and the interior adjusting ring  52  are positioned in the annular compartment of the first end cover  13 . The interior adjusting ring  52  has a toothed side (not numbered) engaging the gear wheel  531 . The adjusting rings  51 ,  52  have opposing guiding slots  511 ,  512  spaced thereon; the guiding slots  511 ,  52  being arranged to form an acute angle with lateral sides of the rings  511 ,  521 . Furthermore, each of the pins  412  of the guiding rods  41  are inserted into a corresponding one of the guiding slots  511  as well as a corresponding one of the guiding slots  512 . Thus, the C-shaped magnets  42  can be displaced in relation to corresponding magnets  32  of the rotor set  3 , i.e. the distance from the C-shaped magnets  42  to the corresponding magnets  32  can be adjusted, by means of turning the adjusting knob  53 ; the slots  521  of the interior ring  52  cause the guiding rods  41  to move along the straight guiding protrusions  11  together with the pins  412  when the adjustment knob  53  is operated.  
     [0022] In using the present power machine, the rotating rack  2  is rotated so that each of the C-shaped magnets  42  of the stator set  4  can attract a corresponding one of the magnets  32  of the stator element moving close thereto, and repel the corresponding one of the magnets  32  of the stator element just moving past it, causing the rotating rack  2  to continue the rotation. Because the connecting bars  31 , which the magnets  32  are fitted along, are turned about central points thereof to have curved shape, the magnets  32  of each stator element of the stator set  3  move close to, and away from, the corresponding C-shaped magnets  42  of the stator elements of the stator set  4  in sequence instead of all at the same time, allowing attraction and repulsion of the magnets  42 ,  32  to persist. Therefore, the shaft  21  can rotate together with the rotating rack  2  with uniform power. The rotational movement is passed onto other machinery connected the shaft  21  such as a generator.  
     [0023] The attraction and repulsion of the magnets will be the biggest if the adjustment member  5  is controlled such that the C-shaped magnets  42  exactly face the corresponding magnet  32  when the magnets  32  are moving over the C-shaped magnets  42 , allowing the present power machine to have biggest power output. The attraction and repulsion of the magnets will be smaller than the above biggest one if the adjustment member  5  is controlled such that the C-shaped magnets  42  face the corresponding magnet  32  in an overlapping manner when the magnets  32  are moving over the C-shaped magnets  42 . The attraction and repulsion of the magnets will be zero if the adjustment member  5  is controlled such that the C-shaped magnets  42  are positioned between two of the magnet  32  when the magnets  32  are moving over the stator element, not able to effect rotation of the shaft  21 .  
     [0024] From the above description, it can be easily understood that the magnetism driven power machine of the present invention has advantages as followings:  
     [0025] 1. The power machine can provide continual power with attraction and repulsion of magnets thereof and without consumption of electricity, therefore it is relatively inexpensive as a device for providing power.  
     [0026] 2. The power output of the present machine can be adjusted with the adjustment member to fit various circumstances.
