Problems solved by technology
However, in the case of constant power, the larger the speed, the smaller the corresponding torque of the motor. Therefore, although the existing two-stage permanent magnet synchronous motor can meet more requirements for no-load operation, in actual use, When the load is completed, the torque started by the load usually cannot meet the existing use requirements

The invention discloses a self-starting three-phase two-stage permanent magnet synchronous motor. The motor comprises: a body, wherein an accommodating cavity is formed in the body and is used for mounting a stator assembly and a rotor assembly; the stator assembly fixedly mounted in the accommodating cavity in the machine body and comprising a plurality of stacked stator units, wherein a stator notch is formed in the inner circumference of each stator unit, and the stator notches in the plurality of mutually stacked stator units form a stator groove; and the rotor assembly comprising a core body, wherein a mouse cage winding is arranged on the outer layer of the core body, the core body is provided with four cavities, the cavities are used for containing magnetic steel pieces, and when the magnetic steel pieces are contained in the cavities, magnetic isolation gaps are formed between the two ends of the magnetic steel pieces and the two ends of the cavities. The structure of the rotor assembly is optimized through optimization design, and the running balance of the motor is improved by reducing stray loss of the motor, so that the starting traction torque is increased.
Description
technical field [0001] The invention relates to the technical field of synchronous motors, in particular to a self-starting three-phase two-stage permanent magnet synchronous motor. Background technique [0002] In recent years, permanent magnet synchronous motors have developed rapidly, and are characterized by high power factor and high efficiency. They have gradually replaced the most commonly used AC asynchronous motors in many occasions. Permanent magnet synchronous motors are usually composed of stators, rotors, end covers, body and other components. The stator structure is usually the same as that of ordinary induction motors, and a drop-through structure is usually used to reduce iron loss during motor operation. The rotor core usually adopts a solid structure, and can also be formed by lamination. The biggest difference between the permanent magnet synchronous motor and other motors is the difference in the structure of the rotor magnetic circuit, which makes its o...
