DETAILED DESCRIPTION

[0034] In order to give examiner more understanding of the features of the present invention and advantage effects which the features can be achieve, some preferred embodiments of the present invention will now be described in greater detail. However, it should be recognized that the preferred embodiments of the present invention are provided for illustration rather than limiting the present invention. In addition, the present invention can be practiced in a wide range of other embodiments besides those explicitly described, and the scope of the present invention is not expressly limited except as specified in the accompanying claims.

[0035] The purpose of the invention is to improve the problem of poor power conversion of the electric motor. Although an external power source can be provided power for the electric motor and the coil of the rotor is powered with current to generate a magnetic field, the induction electromotive force is generated by the magnetic field and the external coil, and then the mechanical energy generated by the external work is inefficient. Therefore, the invention provides a magnetoelectric energy conversion device is applied by an initial voltage V.sub.0 or initial kinetic energy through the external power source to drive the rotation of a magnetic rotary disc in the magnetoelectric energy conversion device. Because the magnetic rotary disc has an optimized circular stacking structure, the magnetoelectric energy conversion device has a good energy conversion efficiency in the process of converting magnetic energy to electrical energy. In addition, it is known that due to the lack of relevant stable structure in the motor, and therefore the performance of the electric motor may be affected by stronger vibration during operation and the electric energy output is unstable due to the increase of torque ripple. In the invention, by optimizing the stable structure of the magnetoelectric energy conversion device, the torque ripple is reduced, and the efficiency of magnetoelectric energy conversion is improved. The detailed descriptions are as follows.

[0036] Based on the above purpose, please refer to FIG. 1, FIG. 2, FIG. 4A and FIG. 4B, the invention proposes a magnetoelectric energy conversion device 1000, which includes a voltage power supply 10, an magnetic rotating device 20, a guide rotor 200, a driving motor module 300 a flywheel module 600 and a control module 700. A power supply 10 is electrically coupled to the driving motor module 300, and the driving motor module 300 is electrically coupled to the magnetic rotating device 20. The power supply 10 is for example a battery with 24V voltage, feeding into the driving motor module 300. The driving motor module 300 is electrically coupled to the magnetic rotating device 20 and the control module 700. The magnetic rotating device 20 includes a magnetic rotor 100, a drive shaft 350 and a flywheel module 600. The drive shaft 350 has for example four shafts for driving the magnetic rotor 100. The control module 700 is used to control the operation of the magnetoelectric energy conversion device 1000. The driving motor module 300 includes a driving circuit to provide the initial voltage V.sub.0 required for the operation of the driving motor winding. The flywheel module 600 is coupled to the driving motor module 300 to drive the flywheel module 600 for rotating and provide the stable operating speed of the magnetic rotor 100, or directly or indirectly drive the flywheel module 600 through the magnetic rotor 100. The flywheel radius of the flywheel module 600 can be adjusted according to the demand. The guide rotor 200 is arranged around the flywheel module 600, and is installed on the guide shaft 200A, and is internally provided with a unidirectional bearing to make the rotation direction of the flywheel module 600 identical. FIG. 3B shows the configuration structure of the guide rotor 200, and the radius of the guide rotor 200 can be adjusted according to the demand. The magnetic rotor 100 includes a magnetic rotary disc 1, which is rotated due to the interaction between the magnetic rotor 100 and the guide rotor 200 to produce rotating mechanical energy. The rotation of the magnetic rotary disc 1 makes the change of magnetic flux to produce induced electromotive force E. The drive shaft module 400 transmits the rotating mechanical energy to the electric motor module 500. That is, the rotating mechanical energy of the magnetic rotor 100, the drive shaft 350 and the flywheel module 600 are transferred to the electric motor module 500 through the drive shaft module 400. In one preferred embodiment of the invention, the driving motor module 300 can be a six-phase winding formed by two sets of three-phase winding in parallel. When the driving motor module needs large torque and low rotating speed, one set of the three-phase winding provides electric energy to the flywheel module; while when the driving motor module needs relatively stable high rotating speed, the six phase winding formed by the two sets of three-phase winding provides electric energy to improve the conversion efficiency of the magnetoelectric energy conversion device.

[0037] In another embodiment of the invention, the driving motor module 300 includes a driving circuit including several power transistors switches. According to the control signal fed by the control module 700, the phase of the first voltage V.sub.a0, the second voltage V.sub.b0 and the third voltage V.sub.c0 are adjusted to control the rotation speed of the driving motor winding, so that the magnetic rotor 100 can be operated by a stable initial voltage V.sub.0 during the operation. The cogging torque that may be generated during the operation of the magnetic rotor 100 due to the instability of the initial voltage V.sub.0 is avoided such that the energy conversion efficiency of the magnetoelectric energy conversion device 1000 does not be reduced. In this embodiment of the invention, the power transistors switches can be, but not limited to, Schottky diodes, fast recovery diodes, and line-frequency diodes, wherein the first voltage V.sub.a0, the second voltage V.sub.b0 and the third voltage V.sub.c0 are fed into the first phase voltage V.sub.a, the second phase voltage V.sub.b and the third phase voltage V.sub.c of the driving motor winding, and the initial voltage V.sub.0, according to basic electricity, its mathematical relationship is as follows:

[00001]$\left[\begin{array}{ccc}{}_{11}^{--}& {}_{12}^{--}& {}_{13}^{--}\\ {}_{21}& {}_{22}& {}_{23}\\ {}_{31}& {}_{32}& {}_{33}\end{array}\right].Math.\left[\begin{array}{c}{V}_{a.Math..Math.0}\\ V_{b.Math..Math.0}\\ V_{c.Math..Math.0}\end{array}\right]=\left[\begin{array}{c}{V}_a\\ V_b\\ V_c\end{array}\right]$$V_0=V_{a.Math..Math.0}+V_{b.Math..Math.0}+V_{c.Math..Math.0};$

[0038] Wherein, .sub.11, .sub.12, .sub.13, .sub.21, .sub.22, .sub.23, .sub.31, .sub.32, .sub.are phase factors of the first voltage V.sub.a0, the second voltage V.sub.b0 and the third voltage V.sub.c0 respectively. In another embodiment of the invention, the phase factor can be adjusted by the control module 700 according to the feeding conditions of the first voltage V.sub.a0, the second voltage V.sub.b0 and the third voltage V.sub.c0, so as to speed up or slow down the driving motor winding 33, maintain the stability of the initial voltage V.sub.0, reduce the torque ripple without reducing the energy conversion efficiency of the magnetoelectric energy conversion device 1000.

[0039] In the invention, the magnetoelectric energy conversion device 1000 has a flywheel module 600. The purpose of the flywheel module 600 of the present invention is used to correct the operation error caused by gravity and vibration of the gear element. The reason why the magnetoelectric energy conversion device 1000 has high efficiency in the conversion of magnetic energy, electric energy and mechanical energy is that the magnetic rotor 100 can operate according to the speed set by the control module 700. As the action of the magnetic rotor 100 itself is not accurate enough, the efficiency of energy conversion will be reduced no matter how the structure of the magnetic rotor 100 is set. Therefore, the invention performs the operation of the flywheel module 600. When the magnetic rotor 100 is affected by the vibration in a certain direction, or the position of the magnetoelectric energy conversion device 1000 itself loses the state of being parallel to the ground, the corresponding position will return to the original state of being parallel to the ground due to the conservation of angular momentum, and the influences in various directions will cancel each other. Thus, the effect of external force is minimized to maintain the stable operation of the magnetoelectric energy conversion device 1000. In addition, the flywheel in the flywheel module 600 can store mechanical energy in the form of rotational kinetic energy when rotating. When the input mechanical energy increases, the rotational speed of the flywheel increases. Relatively, when the flywheel needs to work on the environment, its rotational speed decreases and releases mechanical energy. Therefore, because the flywheel tends to resist the change of rotation speed, when the magnetic rotor 100 rotates, the flywheel can be used as a component to stabilize the rotation speed of the magnetic rotor 100 and make its operation more smoothly.

[0040] As mentioned above, the rotating mechanical energy of the magnetic rotor 100, the drive shaft 350 and the flywheel module 600 are transferred to the electric motor module 500 through the drive shaft module 400. The energy generated by the electric motor module 500 can output to two sets of high and low voltage current transmission systems, and switch each other regularly. For example, as shown in FIG. 2, it illustrates two sets of high and low voltage current transmission systems with high-low voltage power supply of one embodiment. The electric motor module 500 is providing power to a high-low voltage power supply 710 and a high-low voltage power supply 720 which provide power to a battery system 800. The high-low voltage power supply 710 and the high-low voltage power supply 720 can provide a high voltage power and a low voltage power to a battery 702 and a battery 704. For example, the high-low voltage power supply 710 and the high-low voltage power supply 720 can provide a high voltage power and a low voltage power to the battery 702 and the battery 704 in timing mutually switching by the control module as shown in FIG. 3, and thereby outputting output 1, output 2, output 3 and output 4. For example, the high voltage is 26.5 V voltage and the low voltage is 24 V voltage. The battery 702 and the battery 704 are outputting a 50 ampere current. In one example, high-low voltage power supply 710 and the high-low voltage power supply 720 includes a booster (boost circuit) 715, 717 and a voltage regulator 716, 718 respectively coupled to the booster 715 and 717 to output a stable voltage. The booster may be a motor-booster, an Entz booster. As battery power of the first battery 702 is less a pre-determined value, the high-low voltage power supply 710 or the high-low voltage power supply 720 is providing power to the first battery 702 for charging, while the second battery 704 is output a stable voltage. In addition, as battery power of the second battery 704 is less a pre-determined value, the high-low voltage power supply 710 or the high-low voltage power supply 720 is providing power to the second battery 702 for charging, while the first battery 702 is output a stable voltage. In one embodiment, the operating range of the booster is 0-99 volts.

[0041] Please refer to FIG. 4A and FIG. 4C. In one embodiment of the invention, the flywheel module 600 includes a first stage flywheel 61, preferably three flywheels, which is arranged under (at the lower side of) the magnetic rotor 100 and rotating through a first rotating shaft 67a; a second stage flywheel 63, preferably three flywheels, which is arranged under (at the lower side of) the magnetic rotor 100 and rotating through a second rotating shaft 67b. The first stage flywheel 61 and the second stage flywheel 63 are arranged on the first rotating shaft 67a and the second rotating shaft 67b in a concentric circle structure. In an embodiment, the first rotating shaft 67a and the second rotating shaft 67b are respectively arranged on different concentric circles, thus forming the first stage flywheel group and the second stage flywheel group. It should be noted that the first stage flywheel 61 and the second stage flywheel 63 may be referred to as the flywheel module 600, and the number of the flywheel module 600 may have different numbers and object dimension such as diameter, according to the demands of the application. In the first embodiment of the present invention, the rotating shaft 67a and the rotating shaft 67b are connected by a transmission mechanism, such as a belt or a gear set, to the driving motor module 300, which drives the rotating shaft 67a and the rotating shaft 67b to rotate, and individually or simultaneously, directly or indirectly drives the first stage flywheel 61, the second stage flywheel 63 and the magnetic rotor 100 to rotate. In the second embodiment of the present invention, the transmission belt is connected to the driving motor module 300 to drive the first stage flywheel 61 and/or the second stage flywheel 63 for rotating, and thereby driving the magnetic rotor 100 for rotating. In the third embodiment of the present invention, the transmission belt is connected to the driving motor module 300, and transmits the mechanical energy to the magnetic rotor 100, so that the magnetic rotor 100 can drive the first stage flywheel 61 and the second stage flywheel 63 to rotate. In addition, please refer to FIG. 4A, in a preferred embodiment of the invention, a plurality of guide rotors 200 are arranged around the flywheel module 600 and the magnetic rotor 100, and a unidirectional bearing is arranged inside of the guide rotor, so that the magnetoelectric energy conversion device 1000, including each gear element of the magnetic rotor 100 and the flywheel module 600, will not generate the inverse motion due to the inertia during the operation (that is, to ensure the rotation direction in a single direction) to avoid affecting the stability of the rotation of the gear element. In one aspect of the invention, although the flywheel can make the magnetoelectric energy conversion device 1000 stable under the influence of vibration in operation, many flywheels configuration may make the rotational inertia of each gear component in the magnetoelectric energy conversion device 1000 too large, and thereby affecting the efficiency of energy conversion. Therefore, in the embodiment of the invention, the preferred application configuration of the flywheels is 1-6, so as to make the magnetic energy conversion device 1000 have the best balance between the efficiency of energy conversion and the stability of operation.

[0042] In another embodiment of the invention, the flywheel in the flywheel module 600 is arranged under the magnetic rotor 100, meshed with the rotating shaft 67 through the teeth on the wheel rim, and the magnetic rotor 100 is arranged on the rotating shaft 67, so that the flywheel module 600 can be rotated together with the magnetic rotor 100 through the rotating shaft 67. Preferably, the number of the flywheels can be a multiple of three. In the first embodiment, the rotating shaft 67 is connected with the driving motor module 300 through a transmission belt, which drives the rotating shaft 67 to rotate, and simultaneously drives the flywheel and the magnetic rotor 100 to rotate. In the second embodiment, the transmission belt is connected with the driving motor module 300, which drives the flywheel to rotate and drives the magnetic rotor 100 to rotate. In the third embodiment, the transmission belt is connected with the driving motor module 300, and the mechanical energy is transmitted to the magnetic rotor 100, so that the magnetic rotor 100 can drive the flywheel to rotate together.

[0043] In addition, please refer to FIG. 5. In the embodiment of the invention, the magnetoelectric energy conversion device 1000 has a drive shaft module 400 connected with the above-mentioned magnetic rotor 100. The drive shaft module 400 includes a second gear 43, which is arranged on a drive bracket 47, and a drive shaft 45 is connected with the second gear 43 and the drive wheel 49. When the second gear 43 is driven by the above-mentioned magnetic rotor 100, the mechanical energy through rotating of the drive shaft 45 may transmit to the drive wheel 49 provided on the other drive bracket 47.

[0044] In addition, in the above-mentioned embodiments, the drive shaft module 400 may include at least one first gear 41, which is coupled with the second gear 43 and the flywheel module 600. When the flywheel module 600 is placed under (at the lower end of) the drive shaft module 400, the first gear 41 can be installed on the rotating shaft 67, so that the first gear 41 and the second gear 43 can be mutually perpendicularly installed, and the configured space of the magnetoelectric energy conversion device 1000 can be saved in the horizontal direction.

[0045] Please refer to FIG. 6 and FIG. 7 at the same time, FIG. 6 and FIG. 7 respectively show a three-dimensional view and a three-dimensional decomposition view of the magnetic rotor of the present invention. In order to achieve the main purpose of the present invention, the embodiment in FIG. 6 and FIG. 7 includes a magnetic rotary disc. As shown in the figures, according to one or more embodiments, the magnetic rotor 100 of the present invention is substantially composed of a magnetic rotary disc 1, a division plate 3, a division plate 5 and a transmission disc 7. The assemblies all have an axial hole aligned with the identical axis, which can be synchronously rotated according to the axial hole, and the assemblies are fixed together by a plurality of fixing elements 9 (exemplified as screws).

[0046] As mentioned above, the magnetic rotary disc 1 acts as a core assembly of the magnetic rotor 100, which has characteristics of permanent magnetism, and can generate a magnetic field with single magnetic pole and uniformly distributed. The division plate 3 and the division plate 5 are respectively arranged on the upper side and the lower side of the magnetic rotary disc 1, and the function thereof is to protect the magnetic rotary disc 1 while isolating the magnetic fields on the upper side and the lower side of the magnetic rotary disc 1, so as to limit the distribution of the magnetic fields in a plane while avoiding unnecessary magnetic balance off The transmission disc 7 is arranged on the lower side of the division plate 5, which has a plurality of transmission teethes arranged on the peripheral edge of the transmission substrate 7. Through the rotation of the transmission disc 7, the mechanical energy generated by the magnetic rotor 100 can effectively drive other electrical equipment.

[0047] Please refer to FIG. 6 to FIG. 9 simultaneously, wherein FIG. 8 and FIG. 9 respectively show a three-dimensional view and a top view of the magnetic rotary disc of the present invention. As shown in the figures, according to one or more embodiments, the magnetic rotary disc 1 of the present invention is substantially composed of a metal rotary body 13 and a plurality of magnetic elements 11. The metal rotary body 13 is manufactured by metal (exemplified by iron), which may be in the form of a circular disc or a circular ring. The present invention is not limited to any foil ii herein, it may have any suitable appearance. The magnetic elements 11 are arranged on the peripheral edge of the metal rotary body 13 in a uniform distribution. The magnetic elements 11 can be directly attracted on the surface of the peripheral edge of the metal rotary body 13 without other media due to the metal rotary body 13 is formed of metal.

[0048] As mentioned above, the magnetic elements 11 can not only be directly attracted on the surface of the peripheral edge of the metal rotary body 13, but also can be attracted with each other in a way of being not completely overlapped. Accordingly, the magnetic elements 11 are arranged on the peripheral edge of the metal rotary body 13 in a uniform distribution. According to one or more embodiments, the magnetic elements 11 may be in the form of sheet structure having a curvature. Based on the presence of the curvature, the magnetic elements 11 can be more efficiently attracted to each other in a way of being not completely overlapped, and then arranged on the peripheral edge of the metal rotary body 13 in a uniform distribution. Similarly, the size of the curvature decides the amount of the magnetic elements 11. According to one or more embodiments, the amount of the magnetic elements 11 is 23 N or 6N, wherein N is a positive integer between 1 and 16. Accordingly, the optimum range of the amount of the magnetic elements 11 is between 6 and 96.

[0049] Please further refer to FIG. 10 to FIG. 13 simultaneously, wherein FIG. 10 shows the first partial three-dimensional view of the magnetic rotary disc of the present invention, and FIG. 11 to FIG. 13 respectively show the first to the third partial cross-sectional view of the magnetic rotary disc of the present invention. As shown in FIG. 11 and FIG. 13, according to one or more embodiments, the peripheral edge of the metal rotary body 13 of the present invention comprises a plurality of slots 131 in corresponding number, so that the adsorption of the magnetic elements 11 is provided. According to the foregoing, since according to the best embodiment of the present invention, the amount of the magnetic elements 11 is between 6 and 96, the amount of the slots 131 should also be between 6 and 96. With the arrangement of the slots 131, the magnetic elements 11 will be more firmly absorbed on the peripheral edge of the metal rotary body 13 in a uniform distribution, because these can be preset and completed. It is worth noting that the lower side of any magnetic elements 11 is not completely absorbed on the corresponding slots 131, because part of them is attracted on the upper side of the other magnetic elements 11.

[0050] As shown in FIG. 10 to FIG. 12, according to one or more embodiments, the magnetic elements 11 respectively comprises a first magnetic pole portion 111 and a second magnetic pole portion 113, wherein the first magnetic pole portions 111 and the second magnetic pole portions 113 respectively belong to upper portion and lower portion of the magnetic elements 11. According to one or more embodiments, the lower side of the second magnetic pole portion 113 of any magnetic elements 11 and the upper side of the first magnetic pole portion 111 of the other magnetic elements 11 partially attracted each other. Accordingly, only the magnetic force lines of the first magnetic pole portions 111 are retained outside the peripheral edge of the metal rotary body 13. According to the best embodiment of the present invention, the first magnetic pole portion 111 and the second magnetic pole portion 113 of the magnetic elements 11 respectively occupy to a half thereof, i.e., the shape and size of each magnetic elements 11 are the same and can be magnetized into the first magnetic pole portions 111 and the second magnetic pole portions 113 equally, both occupying half of them. Accordingly, the lower side of the second magnetic pole portions 113 of any magnetic elements 11 can half cover the upper side of the first magnetic pole portions 111 of the other magnetic elements 11, so as to implement that only the magnetic force lines of the first magnetic pole portions 111 are retained outside the peripheral edge of the metal rotary body 13.

[0051] It is worth mentioning that, according to one or more embodiments, the first magnetic pole portions 111 and the second magnetic pole portions 113 included in the magnetic elements 11 are not limited to any magnetic poles. In other words, if the first magnetic pole portions 111 are N pole, the second magnetic pole portions 113 are S pole, whereas if the first magnetic pole portions 111 are S pole, the second magnetic pole portions 113 are N pole. The keynote of the present invention is that, there are only the magnetic force lines distribution with single magnetic pole outside the peripheral edge of the metal rotary body 13, whether it is an N pole or an S pole. In addition, since the material of the metal rotary body 13 comprises metal iron and the magnetic elements 11 are directly attracted on the surface of the peripheral edge thereof, the magnetic field between the lower side of the magnetic elements 11 and the metal rotary body 13 will be balanced off. Similarly, the magnetic field between the lower side of the second magnetic pole portions 113 of any magnetic elements 11 and the upper side of the first magnetic pole portions 111 of the other magnetic elements 11 will be also balanced off.

[0052] Please refer to FIG. 14 and FIG. 15, wherein FIG. 14 shows the second partial three-dimensional view of the magnetic rotary disc of the present invention, and FIG. 15 shows the fourth partial cross-sectional view of the magnetic rotary disc of the present invention. As shown in the figures, according to one or more embodiments, in order to make the concentration and reinforcement effect of the magnetic force lines better, the upper side of the first magnetic pole portion 111 of any magnetic elements 11 of each interval of a certain number, and an additional magnetic element 15 can also attract each other. According to one or more embodiments, the additional magnetic element 15 may also be in the form of sheet structure having a curvature. However, it should be noted that, the area of the additional magnetic element 15 should in principle be smaller than its attracted magnetic element 11, because the upper side of the first magnetic pole portion 111 of the attracted magnetic element 11 and the lower side of the second magnetic pole portion 113 of the other magnetic element 11 attract each other. Similarly, due to the amount of the magnetic elements 11 is between 6 and 96 in the best embodiment of the present invention, the upper side of the first magnetic pole portion 111 of the magnetic elements 11 of each interval of 6, and an additional magnetic element 15 can also attract with each other. Accordingly, the amount of the additional magnetic elements 15 could be between 1 and 16.

[0053] As shown in FIG. 15, according to one or more embodiments, the additional magnetic element 15 comprise a first magnetic pole portion 151 and a second magnetic pole portion 153. When the upper side of the first magnetic pole portions 111 of any magnetic elements 11 and the additional magnetic element 15 further attract with each other, the first magnetic pole portion 111 of the magnetic element 11 and the second magnetic pole portion 153 of the additional magnetic element 15 attract each other, and the magnetic field between them will be balanced off. Similarly, when the upper side of the first magnetic pole portions 111 of any magnetic elements 11 and the additional magnetic element 15 further attract with each other, the additional magnetic element 15 half cover the attracted first magnetic pole portions 111 of the magnetic elements 11, so as to implement that only the magnetic force lines of the first magnetic pole portions 111 and the first magnetic pole portion 151 are retained outside the peripheral edge of the metal rotary body 13, i.e., some of the first magnetic pole portions 111 will be covered by the additional magnetic element 15, and the magnetic force lines of the first magnetic pole portions 111 will be replaced with the magnetic force lines of the additional magnetic element 15.

[0054] As shown in FIG. 14 and FIG. 15, according to one or more embodiments, the first magnetic pole portions 151 of the additional magnetic elements 15 also respectively comprises a magnetic force concentration portion 155 and an inclined surface where the magnetic force concentration portion 155 is arranged on. The function of the additional magnetic force concentration portion 155 is to concentrate and strengthen the magnetic forces of the associated magnetic poles, and to make the magnetic forces of the magnetic poles more gradational and more directional, so that the magnetic poles interaction with the external magnetic field can be performed more efficiently. It is worth mentioning that, although the area of the additional magnetic elements 15 should in principle be smaller than its attracted magnetic elements 11, the thickness of thinner side of the additional magnetic elements 15 in the form of sheet structure should be equal to the magnetic elements 11 also in the form of sheet structure, so that the additional magnetic elements 15 will optimize the effect of the concentration and reinforcement of the magnetic forces. In a preferred embodiment, the magnetic field strength of the surface of the magnetic elements 15 ranges from 1000 to 15000 Gauss.

[0055] In an embodiment of the invention, please refer to both FIG. 6 and FIG. 12, which show the operation diagram of the magnetic rotor of the invention. The electric motor module 500, as shown in FIG. 16, including stator and rotor, is installed in the motor housing 51. The driving wheel 49 is coupled with the magnetic rotary disc 1, which drives the driving wheel 49 to rotate with the rotor through the magnetic rotary disc 1. During the rotation of magnetic rotary disc 1, the distribution of magnetic field lines around the rotor will be changed. Based on Lenz's law in electromagnetics, an induced electromotive force (EMF) can be generated by the stator in the direction of resisting the change of magnetic flux. Preferably, the voltage increment of the induced EMF can be increased by more than 0.5-4 times of the initial voltage V.sub.0.

[0056] In addition, according to one or more embodiments, a plurality of guide rotors 200 may be arranged on outside the peripheral edge of the magnetic rotor 100. The guide rotors 200 are mainly composed of a magnetic guide element 21 and a transmission disc 27. The magnetic guide element 21 of the guide rotor 200 is provided corresponding to the magnetic elements 11 or the magnetic elements 15 of the magnetic rotor 100. There is magnetic poles interaction between them. Furthermore, the magnetic guide element 21 of the guide rotor 200 has an inclined surface corresponding to the magnetic force concentration portion 155 on the inclined surface of the magnetic elements 15, so as to optimize the interaction between the magnetic poles. When the magnetic rotor 100 rotates, the magnetic guide element 21 makes the tangent direction of the magnetic rotor 100 be continuously pushed forward during rotation according to the principle of same-polarity repulsion and opposite-polarity attraction, so as to achieve the ideal state that the magnetic rotor 100 can be approximately free from friction resistance during rotation, and thereby reducing the loss of mechanical energy of the magnetic rotor 100. The transmission disc 27 of the guide rotor 200 is provided corresponding to the transmission disc 7 of the magnetic rotor 100. They are engaged with each other.

[0057] It is worth mentioning that, the transmission disc 27 of the magnetic guide element 21 of the guide rotors 200 also has a plurality of transmission teethes, and the amount of the transmission teethes is equal to the amount of the transmission teethes of the transmission substrate 7 of the magnetic rotor 100, so as to be synchronously rotated. Through the interaction between the transmission disc 27 of the guide rotor 200 and the magnetic rotor 100, the magnetic rotor 100 only needs extremely small electric energy supply, then high-efficiency magnetic poles interaction with the guide rotor 200 can be achieved, so as to perform smooth and high-speed rotary motion. Therefore, through the magnetic rotor 100 provided by the present invention, it is only required a very small amount of electric energy to generate a great amount of mechanical energy, and the mechanical energy can generate electric energy more efficiently, thereby implementing the new concept of Power and Power Cogeneration.
