Description

Technical Field

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

[0002] There are two types of electric motors available today. The first is the DC motor, which suffers from complex construction and high cost. The second is the AC motor, which has the advantage of a simple structure and ease of manufacturing. However, these motors suffer from low efficiency and poor performance. In AC and DC motors, permanent magnets are mounted on the rotor or stator. Opposite the permanent magnets are slots in the rotor or stator, each containing a conductive wire. When energized, each coil generates a pair of north and south magnetic poles. However, during operation, only one magnetic pole performs work, while the other pole is transformed into a magnetic circuit plate by the outer iron of the rotor's central axis. This short-circuit with the other pole of the opposite polarity causes the circuit to disappear, or the stator's outer iron frame acts as a magnetic circuit plate, creating a short-circuit with the opposite pole, causing the circuit to disappear. In essence, conventional AC and DC permanent magnet motors lose nearly half their power. This is because the opposite poles generate a closed-circuit power loss, so conventional AC and DC motors can only perform work in one direction.

[0003] After years of intensive research on the internal structure of electric motors, the inventor of the present invention has improved existing electric 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 electric motor, and a bidirectional three-stroke electric motor. The electric motor of the present application is a structural optimization and improvement based on the shortcomings existing in the actual use of bidirectional three-stroke electric motors. The patent "Bidirectional Three-Stroke Electric Motor" 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 prevent the magnetic force in the motor from short-circuiting and closing, 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 and do work, and the power of the motor is much greater than that of a traditional motor. However, subsequent studies found that since the stator and rotor use disc type, the overall structure of the motor is relatively complex. If the production and processing of large motors is more difficult, 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 outward, 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. Utility Model Content

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

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A three-stroke transverse slot salient pole circular motor comprises a rotor and a stator, wherein the rotor is rotatably arranged in the middle of the stator and is provided with rotor salient poles, the number of the rotor salient poles being a;

[0007] The stator is provided with transverse through slots on the inner side, the number of which is b, and coils are wound around the outer peripheries of the transverse through slots, and stator salient poles are formed by energizing the coils; magnetic isolation plates are provided around the outer peripheries of the stator salient poles;

[0008] The number of the rotor salient poles is a≥2 and is a multiple of 2, the number of the transverse slots is b≥3 and is a multiple of 3, wherein the ratio of the rotor salient poles to the transverse slots is always maintained at 2:3, ba=1,2,3,4...A.

[0009] 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 conjunction 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. The second transverse slot is energized, generating an electromagnetic force that continues to attract one of the two rotor salient poles to the stator salient pole, causing the rotor to rotate. The coil in the second transverse slot is then de-energized, while the coil in the third transverse slot is energized, causing the third transverse slot to generate an electromagnetic force that continues to attract one of the two rotor salient poles, causing the rotor to rotate. This completes the drive of the rotor in a single cycle. Repeating the cycle causes the rotor to rotate. At the upper ends of the two rotor salient poles, one salient pole is constantly attracted and pulled by the electromagnetic force of the stator salient pole, causing the rotor to rotate continuously. This is how the three-stroke transverse slot salient pole circular motor was born. A digital inverter is installed on the coil side to allow the coils to be energized in turn.

[0010] 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.

[0011] As mentioned above, there are four magnetic isolation plates on the periphery of the stator salient pole. 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.

[0012] The coil side mentioned above is provided with an energizing frequency converter connected to the coil, and the frequency converter enables the current to energize the coil in sequence.

[0013] The above-mentioned transverse through groove is a convex hollow structure, and the coil is wound on the convex structure.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0015] 1. The utility model has the advantages of simple structure, no permanent magnet structure and low manufacturing cost.

[0016] 2. The utility model 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 working efficiency of the motor.

[0017] 3. In the utility model, the rotor salient poles and the stator salient poles are arranged in a ratio of 2:3. The multiple stator salient poles generate electromagnetic force by circulating electricity in turn, attracting the rotor salient poles to rotate, and the motor has high work efficiency.
