The brushless DC motor using the magnetic force of the magnet, wherein: the moving magnet on the rotor is arranged coaxially with the electromagnetic coil on the stator, and the plane of the rotor does not interfere with the plane of the stator.

The brushless DC motor using the magnetic force of the magnet, wherein: one of the planes of the rotor is provided with two moving magnets, and the two moving magnets are arc-shaped and distributed at intervals of 180 degrees, and the two moving magnets are The spatial angle between the two is smaller than the central angle corresponding to any one of the moving magnets, and the central angles of the two moving magnets are equal; the electromagnetic coils are uniformly distributed on the plane of the stator, and the central angles of the corresponding electromagnetic coils are less than two The spatial angle between the moving magnets.

The brushless DC motor using magnet magnetic force, wherein:

When the front end of the magnet field of any of the moving magnets moves to the center of any one of the electromagnetic coils, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply immediately supplies power to any one of the electromagnetic coils, so that the power supply is immediately supplied to the electromagnetic coil. Any one of the moving magnets rotates in a predetermined direction under the magnetic force of the magnet of any one of the electromagnetic coils;

When the rear end of the magnet field of any of the magnets is moved to the center of any one of the electromagnetic coils, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply immediately disconnects the electromagnetic Power supply to the coil;

The space between the rear end of the magnet field of any one of the magnets and the other moving magnet has the above space, and when the front end of the space moves to the center of any one of the electromagnetic coils, the Hall element at the position is displayed. Providing the signal to the power control system, the power supply immediately supplies power to the any one of the electromagnetic coils, so that any of the moving magnets continues to rotate in a predetermined direction under the gravitational repulsion of the electromagnetic coil;

The space between the rear end of the magnet field of any one of the magnets and the other moving magnet has the above space, and when the rear end of the space moves to the center of any one of the electromagnetic coils, the Hall element at the position is displayed. , providing the signal to the power control system, and the power supply immediately disconnects the power supply of any one of the electromagnetic coils;

When the front end of the magnet magnetic field of the other magnet is moved to the center of any one of the electromagnetic coils, the above-mentioned power supply and power-off steps of the electromagnetic coil are repeated, and the cycle is repeated.

The brushless DC motor using the magnetic force of the magnet, wherein: two dynamic magnets are arranged on the rotor, the positions of the number of moving magnets on each layer are the same, and the two layers of moving magnets are opposite to the N pole, or both The S pole is opposite; the electromagnetic coil on the stator is sandwiched between two layers of moving magnets.

Two magnets of the same shape provide a magnetic field with the same magnetic pole area and magnetic field strength, and the two N poles (or S poles) are opposite each other; the third magnet is placed in the middle of the two N pole magnetic fields, and the third magnet The N-pole and S-pole internal wiring is called the magnet pole axis. The direction of the magnetic pole axis of the third magnet is 90 degrees ± 45 degrees with the direction of the two N-pole magnetic fields. The two magnets are not moving, and the third magnet is oriented. The movement of the magnetic pole in the direction of the N-pole in the axial direction, that is, the movement of the magnetic pole axis at the N pole in the front S pole. Its force is magnetism. Many experts and professors who only acknowledge the existence of suction repulsion and do not recognize the existence of the third force-magnet magnetic force, when answering the direction of motion of the third magnet, only recognize the existence of suction repulsion, the third magnet direction The movement in the direction of the S pole of the magnetic pole axis direction, that is, the movement of the magnetic pole axis at the front pole of the S pole. However, in the above actual experiment, the third magnet moves toward the N pole direction of the magnetic pole axis direction, that is, the magnetic pole axis moves backward at the front S pole by the N pole; not the S pole of the third magnet toward the magnetic pole axis direction thereof. Directional motion, that is, the magnetic pole axis moves in the back direction of the S pole at the front N pole. Existing theories have failed to correctly interpret the newly discovered original inventions.

When two identical magnets become one magnet, the first magnet provides a magnetic field N pole (or S pole), and the second magnet is in the magnetic field N pole provided by the first magnet, and the second magnet has a magnetic pole axis direction The direction of the N-pole magnetic field of the first magnet is 90 degrees ± 45 degrees. The first magnet does not move, and the second magnet receives two forces. One force is the magnetism of the magnet, which is caused by the fact that the direction of the magnetic pole axis of the second magnet is 90 degrees ± 45 degrees with the direction of the N-pole magnetic field of the first magnet. Another force is the resultant force of the suction repulsion. Since the direction of the magnetic pole axis of the second magnet is 90 degrees ± 45 degrees from the direction of the N-pole magnetic field of the first magnet, only the N-pole magnetic field of the first magnet is used, so the second The S pole of one magnet and the N pole of the first magnet generate suction, and the N pole of the second magnet generates a repulsive force with the N pole of the first magnet, and the resultant force of the suction repulsion causes the second magnet to be clockwise or counterclockwise The force of the direction of rotation. When the second magnet in the direction of the magnetic pole axis is provided to move, and the first magnet movement of the magnetic field is provided, the first magnet is not subjected to the suction repulsion.

A space between two adjacent magnets providing a magnetic field N pole (or S pole) in one plane is provided with a magnet providing a magnetic pole axis N-S. A suction repulsion is simultaneously generated between the magnet providing the magnetic pole axis N-S and two adjacent magnets providing the magnetic field, and the S side of the magnet providing the magnetic pole axis N-S is the suction force, and the N side is the repulsive force. The direction of the suction repulsion is the same. The magnetic field provided is unchanged, and the supplied magnetic pole axis is changed from the N-S pole to the S-N pole, and the direction of the suction repulsion is changed by 180 degrees.

The magnet provided above for the magnetic pole axis is changed to an electromagnetic coil, and the electromagnetic coil is fixed on the stator of the motor. When the electromagnetic coil is energized, the magnetic pole axis N-S pole is provided. The magnet that provides the magnetic field above is fixed on the rotor of the motor to provide a magnetic field for rotation. The electromagnetic coil has the same effect as the magnet force and suction repulsion generated by the magnet instead of the magnet that provides the magnetic pole axis.

Embodiments utilizing basic technical solutions:

Embodiment 1 The electromagnetic coil on the upper layer of the stator and the magnet on the rotor. The magnet on the rotor of the magnetic brushless DC motor adopts an arc shape. Generally, the angle is more than 90 degrees, or 120 degrees, or the angle is smaller. . The magnetic poles provided may be upper and lower magnetic fields, or may be internal and external magnetic fields. When the angle is more than 90 degrees or 120 degrees, one layer of magnet on the rotor only uses two magnets 1 and two magnets, and the two magnets are evenly distributed, and the spatial angle between the magnets is also equal. When the angle of the arc-shaped magnet is smaller, the appropriate number is selected so that the angle of the magnet is equal to the angle between the magnets. The magnetic field provided by the magnet on the rotor is required to meet the N-S pole of the magnetic pole axis of the electromagnetic coil on the stator. The strength of the magnetic field provided by the magnet on the rotor is confirmed by the power. The following uses only two magnets in a single magnet as an example.

When only one magnet is used for one layer of magnet on the rotor, the number of electromagnetic coils on the stator is four, and the four electromagnetic coils can be evenly distributed on the same plane (may also be uneven). The electromagnetic coil 1 and the electromagnetic coil 3 are at the same position of the magnetic field of the two magnets on the rotor at 180 degrees; when energized, the magnetic pole axis N-S pole causes the magnets on the rotor to be magnetized in the same direction. The electromagnetic coil 2 and the electromagnetic coil 4 are also 180 degrees apart; since the magnetic pole axis NS pole of the electromagnetic coil 2 and the electromagnetic coil 4 is opposite to the magnetic pole axis NS of the electromagnetic coil 1 and the electromagnetic coil 3, that is, the SN pole, the magnet on the rotor is simultaneously Suction repulsive force, but the direction of the suction repulsive force is the same as the direction of the magnetism of the magnet. The magnet is subjected to the same magnetic force and suction repulsion direction, and the magnet magnetic force and suction repulsion force the rotor to operate normally in the same direction.

When the two magnet magnetic fields on the rotor enter the center of the electromagnetic coil 2 and the electromagnetic coil 4, the magnetic pole axis SN of the electromagnetic coil 2 and the electromagnetic coil 4 are reversed to the NS pole, that is, the direct current power source for the electromagnetic coils 2, 4 is positive. The negative pole is turned upside down. Then, the magnetic force of the magnet generated is the same as the magnetic force of the magnet generated by the electromagnetic coil 1 and the electromagnetic coil 3. Similarly, when the space between the two magnets on the rotor enters the electromagnetic line At the center of the coil 1 and the electromagnetic coil 3, the magnetic pole axis N-S of the electromagnetic coil 1 and the electromagnetic coil 3 are reversed to form an S-N pole, that is, the positive and negative poles of the direct current power source for the electromagnetic coils 1, 3 are reversed. Then, the suction repulsion force generated is the same as the suction repulsion force generated by the electromagnetic coil 2 and the electromagnetic coil 4.

When the two magnet magnetic fields on the rotor are respectively in the electromagnetic coils 1, 2, 3, 4, they are magnetized in the same direction;

When the space between the two magnets on the rotor is in the electromagnetic coils 1, 2, 3, 4, respectively, the suction repulsion in the same direction as the magnetic force of the magnet is received. The positive and negative poles provided by the DC power supply provide different positive and negative poles in different positions.

The DC power supply provides different positive and negative poles in the same way as permanent magnet brushless DC motors. It consists of a Hall element and a power control part. Do not elaborate. Only in time, when the front end of the magnet field on the rotor moves just past the center of the electromagnetic coils 1, 2, 3, 4, the positive-negative pole is immediately provided, and the magnetism of the magnet is generated; when the back end of the magnet field on the rotor moves to the When leaving the center of the electromagnetic coils 1, 2, 3, 4, the power is immediately turned off. Similarly, when the front end of the space between the two magnets on the rotor moves just past the center of the electromagnetic coils 1, 2, 3, 4, the negative pole - the positive pole is immediately provided, generating a suction repulsion; when between the two magnets on the rotor When the rear end of the space moves to the center of the electromagnetic coils 1, 2, 3, 4, the power is immediately turned off. The electromagnetic coils 1, 2, 3, 4 have a very short time from power-off to power supply, and are powered by about 95% of the time. Because when the rear end of the magnet field on the rotor moves to the center of the electromagnetic coil 1, 2, 3, 4, the power is immediately turned off, and the front end of the space between the two magnets on the rotor immediately moves to the electromagnetic coil 1, At the center of 2, 3, and 4, the time is extremely short and the power-off time is extremely short. If the above structure uses only two electromagnetic coils, the power is supplied to the magnetic field of the magnet on the rotor, and no power is supplied to the space between the two magnets; when the space between the two magnets is not supplied, the core of the electromagnetic coil Will be subjected to the suction of the magnet on the rotor, which will reduce the output power, ie reduce the efficiency. In the above structure, the electromagnetic coil is supplied with power in the space between the two magnets, so that the direction of the suction repulsion is the same as the direction of the magnetic force of the magnet, and there is no effect of reducing the efficiency. The shaft is the same as a normal motor.

Embodiment 2: One layer of electromagnetic coil on the stator, two layers of magnets on the rotor, and two layers of magnets on the rotor of the magnetic brushless DC motor. The two layers of magnets are placed one above the other, and two layers of two uniformly distributed magnets are arranged on each layer. The magnets are of equal size and the four magnets are opposite each other. The polarity between the two magnets is N or S pole, and a layer of electromagnetic coil on the stator is between the upper and lower layers of the rotor. Others are the same as in the first embodiment.

Beneficial effects:

The force of the movement of the magnet is magnet magnetism, suction, and repulsive force, all of which are magnets and electromagnetic coils. The force generated between. All of the solenoids are powered over approximately 95% of the time to force the rotor, and at the same output power, the device is small. The device is subjected to a suction repulsion in the space between the two magnetic fields, the direction of which is the same as the direction of movement of the rotor; the energization time of each of the electromagnetic coils of the permanent magnet brushless DC motor does not utilize the suction repulsion; when it is powered off, all Each electromagnetic coil also does not utilize suction repulsion. Using magnet magnetism, suction, and repulsive force, the efficiency of the device is higher than that of the permanent magnet brushless DC motor, which is energy-saving.

Preferred Embodiment 1: A magnet magnetic brushless DC motor having a layer of electromagnetic coil on the stator and a layer of magnet on the rotor.

1 is a schematic view of a magnet magnetic brushless DC motor with a layer of electromagnetic coil on the stator and a layer of magnet on the rotor. The moving magnet on the rotor uses two arc-shaped magnets. The two arc-shaped moving magnets D1 and D2 are used, the upper side is the N pole, and the lower side is the S pole. The angle of the two arc-shaped moving magnets is larger than the angle of the gap between the two arc-shaped moving magnets. The magnets D1 and D2 are mounted on the non-magnetically conductive plate B, and the magnets D1 and D2 are on both sides of the shaft, 180 degrees apart. The plate B is fixed to the shaft ZH of the motor.

The electromagnetic coils on the stator are X1, X2, X3, X4, a total of four, the data, size, winding direction are the same, fixed at 90 degrees, evenly distributed (electromagnetic coils X1, X2, X3, X4 and rotor on the stator) The upper magnets D1 and D2 are arranged coaxially, and the plane of the rotor does not interfere with the plane of the stator); the lengths of the respective electromagnetic coils X1, X2, X3 and X4 are smaller than the length of the space between the two moving magnets D1 and D2 of the rotor. The width is adapted to the width of the two magnet fields. The distance between the electromagnetic coils X1, X2, X3, X4 on the stator and the moving magnets D1, D2 on the rotor is as small as possible. The electromagnetic coils X1, X2, X3, X4 are on a plane above the moving magnets D1, D2 of the rotor. As shown in Fig. 1, the electromagnetic coil X1 is on the magnetic field N pole of the moving magnet D1, and the electromagnetic coil X3 is on the magnetic field N pole of the moving magnet D2; the power supply of the electromagnetic coil X1, X3 is the positive side on the right side and the negative side on the left side. The generated magnetic pole is the N pole on the right side and the S pole on the left side, that is, the magnetic pole axis NS pole, and the magnets D1 and D2 are magnetized by the magnet. The moving magnet moves counterclockwise under the action of the magnetism of the magnet. As shown in Figure 1, the electromagnetic coils X2, X4 in the space between the two moving magnets D1, D2 on the rotor, the power supply of the electromagnetic coil X2, X4 is the right side is the negative pole, the left side is the positive pole, the generated magnetic pole is the right The side is the S pole and the left side is the N pole; the electromagnetic coil does not move, the N pole and the N pole of the moving magnet D1, D2 generate a repulsive force, and the moving magnets D1 and D2 are subjected to the repulsive force to move counterclockwise; the S pole and the moving magnet The N poles of D1 and D2 generate suction, and the magnets D1 and D2 are subjected to suction to move counterclockwise. When the electromagnetic coils X1, X3 enter the space between the two moving magnets D1, D2, when the electromagnetic coils X2, X4 enter the magnetic fields of the two magnets on the rotor, respectively, different positive and negative electrodes are provided, and the moving magnet is The magnet magnetic force and the suction repulsion continue to move counterclockwise. The above motion is continuously provided and the rotor is rotated.

The method of providing different positive and negative poles for the DC power supply is the same as that of the permanent magnet brushless DC motor, and is composed of a Hall element and a power control part. The following is a brief description: taking the electromagnetic coil X1 as an example, when the front end of the magnet field of the moving magnet D1 moves just past the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power control system. The power supply immediately supplies the positive pole of the magnet to the electromagnetic coil X1 to generate the magnetism of the magnet; when the rear end of the magnet field of the magnet D1 moves to the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is displayed. Provided to the power control system, the power supply is immediately powered off. Similarly, when the rear end of the magnet field of the magnet D1 moves away from the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply immediately supplies the magnetic force to the electromagnetic coil X1. The opposite positive pole negative electrode; when the electromagnetic coil X1 moves between the moving magnet D1 and the moving magnet D2, a suction repulsion is generated between the electromagnetic coil X1 and the moving magnet D1, and the suction repulsion still causes the moving magnet D1 to rotate in the counterclockwise direction. When the front end of the magnet field of the magnet D2 moves to the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply is immediately powered off to the electromagnetic coil X1, and the suction repulsion disappears; When the front end of the magnet magnetic field of D2 moves just past the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply immediately supplies the positive cathode of the electromagnetic coil X1 to generate the magnet magnetic force; When the rear end of the magnet field of the magnet D2 moves to the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power is immediately turned off. Similarly, when the rear end of the magnet field of the moving magnet D2 moves away from the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply immediately supplies the magnetic force to the electromagnetic coil X1. The opposite positive pole; when the electromagnetic coil X1 moves between the moving magnet D2 and the moving magnet D1, a suction repulsion is generated between the electromagnetic coil X1 and the moving magnet D1. This suction repulsion still causes the moving magnet D1 to rotate in a counterclockwise direction. When the front end of the magnet field of the magnet D1 moves to the center of the electromagnetic coil X1, the Hall element at the position is displayed, and the signal is supplied to the power supply control system, and the power supply is immediately powered off to the electromagnetic coil X1, and the suction repulsion disappears; The magnet field of the magnet D1 enters the electromagnetic coil X1 as described above.

The electromagnetic coils X2, X3, and X4 are subjected to the same force and operation as the electromagnetic coil X1.

As can be seen from the above description, the time period from the power-off to the power supply of the electromagnetic coils X1, X2, X3, and X4 is extremely short, and power is supplied for about 95% or more of the time. Because when the back end of the magnet field on the rotor moves to the center of the electromagnetic coils X1, X2, X3, and X4, the power is immediately turned off, and the front end of the space between the two moving magnets D1 and D2 on the rotor immediately moves to The center of the electromagnetic coils X1, X2, X3, and X4 has a very short time. In the above structure, the electromagnetic coil is supplied with power in the space between the two moving magnets D1 and D2 so that the direction of the suction repulsion is the same as the direction of the magnet magnetic force, and there is no effect of reducing the efficiency. The shaft is the same as a normal motor. The above has a prototype demonstration.
