Abstract
Description
[Technical Field]
[0001] The present invention relates to a homopolar vector rotary motor. [Background technology]
[0002] There are many types of motors, but their basic structure mainly consists of a stator and a rotor. The stator is stationary in space and does not move, while the rotor rotates around an axis and is supported by bearings. There is a certain amount of air gap between the stator and rotor, allowing the rotor to rotate freely.
[0003] Motors can be divided into DC motors and AC motors, and the principle of DC motors is that the stator is stationary and the rotor moves in the direction of the force generated by alternating current.In AC motors, alternating current is passed through the stator winding coil to generate a rotating magnetic field, which attracts the rotor and causes it to rotate together.
[0004] In the case of a typical three-phase motor, the three-phase AC is composed of three phases shifted by 120 degrees and of equal magnitude and frequency. Under the influence of the magnetic field of the wound stator, the central conductor generates an induced current based on Fleming's right-hand rule. As the AC power supply changes, the magnetic poles also continue to rotate. Since the direction of motion of the conductor in the moving magnetic field coincides with the magnetic field, the rotor rotates accordingly.
[0005] Most general household AC power sources are single-phase, and because single-phase AC only has one set of current whose magnitude and direction change over time, the magnetic field of this current cannot be used directly to drive the rotor. For this reason, compared to a three-phase induction motor which only has a running winding, a single-phase induction motor requires a separate starting winding, and the phase of the starting winding must be advanced by 90 degrees from the running winding to ensure rotor movement. Summary of the Invention [Problem to be solved by the invention]
[0006] It is an object of the present invention to provide a homopolar vector rotary motor. [Means for solving the problem]
[0007] The present invention will be described below. The homopolar vector rotation motor described in claim 1 includes a power supply control unit, a stator, and a rotor, The stator comprises a stator body and a plurality of electromagnets equiangularly arranged along the circumference of the stator body, the stator body is fixedly installed and a central shaft is movably inserted therethrough, and the plurality of electromagnets are electrically connected to the power supply control unit; the rotor includes a rotor body and a plurality of magnets equiangularly arranged along the circumference of the rotor body, the rotor body being fixed to the central shaft; When the rotor body rotates relative to the stator body along the central axis and the positions of the plurality of magnets correspond to the electromagnets, the power supply control unit controls the plurality of electromagnets to energize them, causing the plurality of electromagnets to generate electromagnetic forces that are the same as the magnetism of the plurality of magnets, thereby causing the rotor body to continue rotating due to the mutually repulsive magnetic forces; When the rotor body rotates relative to the stator body and the positions of the magnets no longer correspond to the positions of the electromagnets, the power supply control unit controls the electromagnets to cut off power to them so that they no longer generate electromagnetic force. At this time, the rotor body continues to rotate due to the inertia of rotation, and when the positions of the magnets again correspond to the positions of the electromagnets, the power supply control unit controls the electromagnets to again supply power to them so that they generate electromagnetic force, causing the rotor body to continue rotating and performing circulating operation. The present invention can reduce power consumption by half by rotating the rotor by combining intermittent power supply with mutually repulsive magnetic forces.
[0008] The homopolar vector rotary motor described in claim 2 is characterized in that, when the plurality of electromagnets described in claim 1 are energized, each of the plurality of electromagnets generates an electromagnetic force of opposite polarity on opposite sides in the radial direction of the stator body, The plurality of magnets installed on the rotor body include a plurality of first magnets arranged radially outside the rotor body and a plurality of second magnets arranged radially inside the rotor body, and the plurality of first magnets and the plurality of second magnets have magnetic forces that repel each other with the opposing sides of the plurality of electromagnets. The present invention generates electromagnetic forces on the opposing sides of the electromagnets, and by using the first magnets arranged radially outside and the second magnets arranged radially inside, it is possible to double the torque and reduce power consumption to about one-quarter.

[0010] The homopolar vector rotary motor described in claim 4 is characterized in that the rotor body in claim 2 includes a first rotor body and a second rotor body that are separated from each other and fixed to the central axis in a coaxial manner, an outer wall is formed on the outer periphery of the first rotor body, the outer diameter of the second rotor body is smaller than the inner diameter of the outer wall, the plurality of first magnets are arranged on the edge of the outer wall, and the plurality of second magnets are arranged on the outer periphery of the second rotor body, The plurality of first electromagnets are installed on the outer periphery of the stator body, the plurality of second electromagnets are installed on the inner periphery of the stator body, and the stator body is disposed between the first rotor body and the second rotor body.

With this structure, as the rotor rotates relative to the stator, the first magnet and the second magnet approach the electromagnet while gradually shortening the distance between them, and when the distance between them becomes shortest, the electromagnet pushes the first magnet and the second magnet with a repulsive force, causing the rotor body to rotate.
[0012] The homopolar vector rotation motor described in claim 6 is characterized in that the rotor body of claim 1 includes a first rotor body and a second rotor body that are separated from each other, arranged on opposite sides of the stator body in the axial direction, and are coaxially fixed to the central axis; The plurality of magnets includes a plurality of first magnets installed on the first rotor body and a plurality of second magnets installed on the second rotor body; When the plurality of electromagnets are energized, they generate electromagnetic forces on opposite sides of the rotor body in the axial direction, and the plurality of electromagnets are arranged as a plurality of rings along different diametric positions of the stator body; the plurality of first magnets are arranged as a plurality of rings along different diametric positions of the first rotor body, and the plurality of first magnets correspond to one side of the plurality of electromagnets; The plurality of second magnets are arranged as a plurality of rings along different diametric positions of the second rotor body, and the plurality of second magnets correspond to the other side of the plurality of electromagnets.

[0014] The terms "first," "second," etc. used in the text are intended to distinguish between components of the same or similar nature, and do not limit the order, order, size, etc., of the components. [Example]
[0015] As shown in Figures 1 and 2, the homopolar vector rotary motor of the present invention includes a power supply control unit 10, a stator 20, and a rotor 30. The stator 20 includes a disk-shaped stator body 201 and a plurality of electromagnets 202 equiangularly arranged around the circumference of the stator body 201. The stator body 201 is fixedly installed in a housing 50 and cannot rotate, and a central shaft 40 is inserted through it. A bearing is installed between the central shaft 40 and the stator body 201, allowing the central shaft 40 to rotate freely relative to the stator body 201. The central shaft 40 is fitted with a bearing and installed in the housing 50, allowing the central shaft 40 to rotate freely on the housing 50, but the stator body 201 is fixed and cannot rotate. The plurality of electromagnets 202 are electrically connected to the power supply control unit 10, and are controlled by the power supply control unit 10 to intermittently supply direct current to the electromagnets 202, thereby forming magnetism in the electromagnets 202. Specifically, the plurality of electromagnets 202 are arranged on the stator 20, and when the power supply control unit 10 supplies direct current to the plurality of electromagnets 202 to energize them, each of the plurality of electromagnets 202 generates electromagnetic forces of opposite polarities on opposite radial sides of the stator body 201.
[0016] More specifically, the plurality of electromagnets 202 includes a plurality of first electromagnets 202A and a plurality of second electromagnets 202B. A protruding wall 2011 may be formed on one side of the outer periphery of the stator body 20, and the plurality of first electromagnets 202A may be installed equiangularly around the circumference on the outside of the protruding wall 2011, and the plurality of second electromagnets 202B may be installed equiangularly around the circumference on the inside of the protruding wall 2011. The plurality of first electromagnets 202A and second electromagnets 202B are connected to the power supply control unit 10 by conductors, which may pass through passages (not shown) provided in the stator body 201 and be electrically connected to the first electromagnets 202A and second electromagnets 202B.
[0017] The rotor 30 comprises a disk-shaped rotor body 301, with a plurality of first magnets 302A arranged equiangularly around the circumference on the radially outer side of the rotor body 301, and a plurality of second magnets 302B arranged equiangularly around the circumference on the radially inner side of the rotor body 301, with the first magnets 302A and second magnets 302B each having the same magnetic properties as the electromagnetic forces generated on opposite sides of the electromagnet 202, i.e., the first magnet 302A has a magnetic force that repels the electromagnetic force generated by the first electromagnet 202A, and the second magnet 302B has a magnetic force that repels the electromagnetic force generated by the second electromagnet 202B. More specifically, the rotor body 301 is formed with an outer wall 3011 located radially outward and an inner wall 3012 located radially inward, with the plurality of first magnets 302A arranged on the outer wall 3011 and the plurality of second magnets 302B arranged on the inner wall 3012. The rotor body 301 is fixed to the central axis 40 and can freely rotate along with the central axis 40. Furthermore, the rotor body 30 and the stator body 20 are arranged coaxially around the central axis 40, with the protruding wall 2011 located between the outer wall 3011 and the inner wall 3012 after arrangement, and the position of the locus of the first magnet 302A as it revolves around the circumference corresponds to the virtual circumferential position of the first electromagnet 202A, and the position of the locus of the second magnet 302B as it revolves around the circumference corresponds to the virtual circumferential position of the second electromagnet 202B.
[0018] 3, in the preferred embodiment of the present invention, the opposing surfaces of first electromagnet 202A and first magnet 302A are formed as flat surface 2021A and inclined surface 3021A, respectively, with opposing ends of flat surface 2021A forming first point P1 and second point P2 at equal heights, and opposing ends of inclined surface 3021A forming third point P3 and fourth point P4 at unequal heights. That is, when flat surface 2021A and inclined surface 3021A face each other, the distance between first point P1 and third point P3 is smaller than the distance between second point P2 and fourth point P4. 4, when rotor body 301 rotates clockwise, first magnet 302A moves toward first electromagnet 202A. As first magnet 302A approaches, the distance between first point P1 on flat surface 2021A and fourth point P4 on inclined surface 3021A gradually decreases in the direction from fourth point P4 to third point P3. As a result, first magnet 302A moves smoothly to the position of first electromagnet 202A while receiving a relatively small repulsive force. When the distance between third point P3 on inclined surface 3021A and first point P1 on flat surface 2021A becomes minimum, the electromagnetic force generated by first electromagnet 202A pushes first magnet 302A in the clockwise direction with a repulsive force, causing it to rotate (as shown in FIG. 4), thereby allowing rotor body 301 to continue rotating without stopping. Similarly, the surfaces of second electromagnet 202B and second magnet 302B facing each other are formed in the same manner as the flat surface and inclined surface described above, and have the same effects as those described above, so repeated description will not be repeated here.
[0019] The operation method of the homopolar vector rotary motor of the present invention will now be described. The power supply control unit 10 of the present invention supplies DC to each electromagnet 202 in an intermittent power supply manner, pushing and rotating the rotor body 301. More specifically, as shown in Figure 5, when the rotor body 301 rotates relative to the stator body 201 along the central axis 40, the power supply control unit 10 waits until each first magnet 302A corresponds to the position of the first electromagnet 202A and each second magnet 302B corresponds to the position of the second electromagnet 202B before controlling the DC to be supplied to each first electromagnet 202A and each second electromagnet 202B according to a preset computer program. This generates an electromagnetic force in the first electromagnet 202A and the second electromagnet 202B that is the same as the magnetic force of the first magnet 302A and the second magnet 302B, respectively. The resulting repulsive magnetic force pushes and continues to rotate the rotor body 301. Then, when the rotor body 301 rotates relative to the stator body 201, and each first magnet 302A no longer corresponds to the position of the first electromagnet 202A, and each second magnet 302B no longer corresponds to the position of the second electromagnet 202B, the power supply control unit 10 interrupts the supply of DC to each of the first electromagnets 202A and second electromagnets 202B according to a preset computer program, so that no electromagnetic force is generated. At this time, the rotor body 301 continues to rotate due to the inertia of rotation, and when each of the first magnets 302A and second magnets 302B once again corresponds to the plurality of first electromagnets 202A and second electromagnets 202B, respectively, the power supply control unit 10 again controls the supply of current to the first electromagnets 202A and second electromagnets 202B to generate electromagnetic force, which pushes the rotor body 301 and continues to rotate, thereby performing circulation operation.
[0020] In the homopolar vector rotary motor of the present invention, the power supply control unit 10 supplies DC intermittently, thereby reducing power consumption by approximately half. In addition, the first electromagnet 202A and the second electromagnet 202B jointly push the first magnet 302A and the second magnet 302B with a repulsive force, driving and rotating the rotor body 301, and achieving twice the torque output from the central shaft 40. [Example]
[0021] 6 shows a second embodiment of the homopolar vector rotary motor of the present invention, wherein the rotor body can include a first rotor body 301A and a second rotor body 301B that are separated from each other and coaxially fixed to the central axis 40, an outer wall 3011A is formed around the outer periphery of the first rotor body 301A, the outer diameter of the second rotor body 301B is smaller than the inner diameter of the outer wall 3011A, a plurality of first magnets 302A are circumferentially arranged at the edge of the outer wall 3011A, and a plurality of second magnets 302B are circumferentially arranged around the outer periphery of the second rotor body 301B. A plurality of first electromagnets 202A are installed on the outer periphery of the stator body 201, a plurality of second electromagnets 202B are installed on the inner periphery, and the stator body 201 is fixed to the housing 50 and disposed between the first rotor body 301A and the second rotor body 301B, so that the position of the trajectory of the first magnet 302A as it rotates along the circumference corresponds to the virtual circumferential position of the first electromagnet 202A, and the position of the trajectory of the second magnet 302B as it rotates along the circumference corresponds to the virtual circumferential position of the second electromagnet 202B.
[0022] Similarly, the power supply control unit 10 supplies DC to each electromagnet in an intermittent power supply manner to push and rotate the rotor body 301A. That is, when the first rotor body 301A and the second rotor body 301B rotate relative to the stator body 201 along the central axis 40, the power supply control unit 10 waits until each first magnet 302A corresponds to the position of the first electromagnet 202A and each second magnet 302B corresponds to the position of the second electromagnet 202B, and then controls DC to supply DC to each first electromagnet 202A and each second electromagnet 202B according to a preset computer program, causing the first electromagnet 202A and the second electromagnet 202B to generate electromagnetic forces that are the same as the magnetic forces of the first magnet 302A and the second magnet 302B, respectively. The resulting repulsive magnetic forces push and move the first rotor body 301A and the second rotor body 301B, allowing them to continue rotating synchronously. When the first rotor body 301A and the second rotor body 301B rotate relative to the stator body 201, and the first magnets 302A do not correspond to the positions of the first electromagnets 202A, and the second magnets 302B do not correspond to the positions of the second electromagnets 202B, the power supply control unit 10 stops supplying current to the first electromagnets 202A and the second electromagnets 202B according to a preset computer program, so that electromagnetic force is not generated. The first rotor body 301A and the second rotor body 301B continue to rotate due to rotational inertia, and when the positions of the first magnets 302A and the second magnets 302B again correspond to the plurality of first electromagnets 202A and the plurality of second electromagnets 202B, respectively, the power supply control unit 10 again controls the power supply to the first electromagnets 202A and the second electromagnets 202B to generate electromagnetic force, which pushes the first rotor body 301A and the second rotor body 301B and continues to rotate, thereby performing a circular operation. [Example]
[0023] 7 and 8 show a third embodiment of the homopolar vector rotation motor of the present invention, wherein the rotor body includes a first rotor body 301C and a second rotor body 301D that are separated from each other and arranged on opposite sides of the stator body 201 along the central axis 40 and are coaxially fixed to the central axis 40, a first magnet 302A and a second magnet 302B that are arranged as a plurality of rings along different diametric positions of the first rotor body 301C and the second rotor body 301D, and a first electromagnet 202A and a second electromagnet 202B that are arranged as a plurality of rings along different diametric positions of the stator body 201, and the plurality of first magnets 302A located on the first rotor body 301C and the second rotor body 301D correspond to both sides of the plurality of first electromagnets 202A, respectively, and simultaneously the plurality of second magnets 302B correspond to both sides of the plurality of second electromagnets 202B, respectively. In addition, a conductive rotor 60 is further installed on the central shaft 40, and a plurality of conductive portions 61 are formed on the circumferential surface of the conductive rotor 60 and are equally spaced apart, with insulating portions 62 between adjacent conductive portions 61, and the included angle between adjacent conductive portions 61 is equal to the included angle between adjacent first magnets 302A or the included angle between adjacent second magnets 302B, and the conductive portions 61 are electrically connected to each of the first electromagnets 202A and second electromagnets 202B by conductors. A power line is connected to the power supply control unit 10, and a conductive rod is installed in the power line, and the conductive rod contacts the circumferential surface of the conductive rotor 60.
[0024] According to the third embodiment, when the first rotor body 301C and the second rotor body 301D rotate together with the central axis 40, the conductive rotor 60 also rotates synchronously. At the same time, when the first magnet 302A and the second magnet 203B of the first rotor body 301C and the second rotor body 301D reach the positions corresponding to the first electromagnet 202A and the second electromagnet 202B, the conductive rod also contacts the conductive part 61 of the conductive rotor 60, so that the power supply control unit 10 supplies direct current to the plurality of first electromagnets through the conductive part 61. Electricity is passed through magnets 202A and second electromagnets 202B, generating electromagnetic forces of opposite polarities on opposite axial sides of each of the plurality of first electromagnets 202A and second electromagnets 202B, and as a result, the plurality of first magnets 302A and the plurality of second magnets 302B each have a magnetic force that repels the opposite axial sides of the plurality of first electromagnets 202A and second electromagnets 202B, pushing and rotating first rotor body 301C and second rotor body 301D, and outputting torque to central shaft 40.
