Description

Technical Field

[0001] The invention relates to the technical field of electric motors, and in particular to a three-stroke horizontal through-slot salient-pole circular electric motor. Background Art

[0002] There are two types of electric motors. The first type is a DC motor, which has the disadvantages of complex structure and high cost. The second type is an AC motor, which has the advantages of simple structure and convenient manufacturing, but the efficiency of this type of motor is low and the use effect is poor. Among them, a permanent magnet is installed on the rotor or stator of the AC and DC motor. The opposite of the permanent magnet is the rotor or stator. They are both provided with pits, and a conductive coil is embedded in the pit. When the coil is powered on, each coil can generate a pair of north and south magnetic poles. However, during operation, only one magnetic pole works, and the other magnetic pole is turned into a magnetic circuit iron plate by the outer round iron of the rotor center axis, and then short-circuited with other opposite magnetic poles, resulting in the disappearance of closure, or turned into a magnetic circuit iron plate by the outer round iron frame of the stator, resulting in the disappearance of short-circuit closure with the opposite magnetic poles. In fact, the power of traditional AC and DC permanent magnet motors is nearly half lost. Since the other electromagnetic poles generate closed-circuit power loss, traditional AC and DC motors can only work in one direction.

[0003] After years of intensive research on the internal structure of the motor, the inventor has improved the existing motors through repeated tests and experiments, and has successively applied for a device to replace the crankshaft system of an internal combustion engine, a bidirectional motor, and a bidirectional three-stroke motor. The motor of the present application is a structural optimization and improvement based on the deficiencies existing in the actual use of the bidirectional three-stroke motor. The patent "Bidirectional Three-Stroke Motor" that was applied for and disclosed in 2016 has the following working principle: in a motor coil, north and south magnetic poles are provided, and the principle that both magnetic pole surfaces of the coil can do work is used to make the magnetic force in the motor not short-circuit closed, thereby reducing the power loss of the motor. When the motor is in use, a pair of north and south magnetic poles are generated in an energized coil, and the magnetic field lines are cut vertically by the coil, so that both magnetic poles of the coil are subjected to force to do work, and the power of the motor is much greater than that of a traditional motor. However, subsequent studies found that due to the disc-type stator and rotor, the overall structure of the motor is relatively complex. If large-scale motors are manufactured and processed, it will be more difficult and the cost will increase accordingly. At the same time, a large part of the magnetic force generated by the internal coil during the operation of the existing motor will be lost to the outside, resulting in partial energy loss and waste. Therefore, the applicant has continued to study and improve the internal structure of the motor to reduce magnetic loss and improve the motor's work efficiency. Summary of the invention

[0004] In view of the shortcomings that the electric motor has a complex structure, is not easy to be processed into a large electric motor, and the magnetic force will be lost outward during the operation of the motor, the present invention provides a three-stroke transverse slot salient pole circular motor with a simple structure, which is convenient for the processing and manufacturing of large electric motors and can effectively reduce the magnetic force loss, reduce waste and improve the working power of the motor.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A three-stroke horizontal through-slot salient pole circular motor comprises a rotor and a stator, wherein the rotor is rotatably arranged in the middle of the stator, and the rotor is provided with rotor salient poles, and the number of the rotor salient poles is a; The inner side of the stator is provided with transverse through slots, the number of which is b, and the outer periphery of the transverse through slots is wound with coils, and the stator salient poles are formed by energizing the coils; the outer periphery of the stator salient poles is provided with magnetic isolation plates; The number of the rotor salient poles is a≥2 and is a multiple of 2, the number of the transverse through slots is b≥3 and is a multiple of 3, wherein the ratio of the rotor salient poles to the transverse through slots is always maintained at 2:3, ba=1,2,3,4...A.

[0006] In the present invention, rotor salient poles related to multiples of 2 and transverse slots related to multiples of 3 are set. Stator salient poles are formed by energizing the coils in the transverse slots. The rotating salient poles work in coordination with the stator salient poles, which can effectively improve the working power of the motor. Taking 2 rotor salient poles and 3 transverse slots as an example, the principle is: when working, the coils connected to the 3 transverse slots are energized in turn, so that the corresponding transverse slots generate electromagnetic force. At this time, one of the stator salient poles in the 2 rotor salient poles is attracted by the electromagnetic force, causing the rotor to rotate; then the coil in the first transverse slot is de-energized, and the coil in the second transverse slot is energized at the same time. , so that the second transverse slot generates electromagnetic force, which continues to attract one of the two rotor salient poles to the stator salient pole, so that the rotor rotates; then the coil in the second transverse slot is de-energized, and the coil in the third transverse slot is energized, so that the third transverse slot generates electromagnetic force, which continues to attract one of the two rotor salient poles to rotate the rotor, so that the drive of the rotor in a single cycle is completed, and the repeated cycle makes the rotor rotate. At the upper end of the two salient poles of the rotor, there is always a salient pole that is constantly attracted by the electromagnetic force of the stator salient pole, so that the rotor keeps rotating, and the three-stroke transverse slot salient pole circular motor is born. The above-mentioned coil side is equipped with a digital inverter to make the coils energized in turn.

[0007] The above-mentioned stator includes a body and a bearing seat, wherein the middle of the body is a cavity, and bearing seats are installed at both ends. Transverse grooves are evenly installed along the inner wall of the cavity, and magnetic isolation plates are also fixedly installed on the inner wall of the body around the transverse grooves; power shafts are fixed at both ends of the rotor, and the power shafts are matched and installed in the bearing seats at both ends of the body.

[0008] As mentioned above, there are four magnetic isolation plates on the outer periphery of the stator salient pole, and the four magnetic isolation plates are connected in sequence to form a ring structure, which wraps the stator salient pole in the middle to prevent the loss of electromagnetic force.

[0009] The coil side described above is provided with a power-on inverter connected to the coil, and the inverter enables the current to energize the coil in sequence.

[0010] The above-mentioned transverse through groove is a convex hollow structure, and the coil is wound on the convex structure.

[0011] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention has the advantages of simple structure, no permanent magnet structure and low manufacturing cost.

[0012] 2. The present invention can prevent the electromagnetic force generated by the coil from being lost outward through the design of the magnetic isolation plate, thereby improving the electromagnetic effect of the motor and further enhancing the work efficiency of the motor.

[0013] 3. In the present invention, the rotor salient poles and the stator salient poles are arranged in a quantity ratio of 2:3. The multiple stator salient poles generate electromagnetic force by passing electricity in turn, attracting the rotor salient poles to rotate, and the motor has high work efficiency.
