Problems solved by technology

[0002] At present, the stator of a disc motor includes a stator core and a coil winding. Generally, the stator core is wound into a disc shape with a silicon steel sheet, and the coil is slotted on one end face of the disc. The stator of this motor has a simple structure and high efficiency. High, but the stator core processing process is complicated, the processing cycle is long, and when the motor speed is high, the ferromagnetic loss of the silicon steel sheet is very large, which seriously affects the efficiency of the motor
Therefore, in order to further reduce the core loss of the motor, the stator can adopt a coreless structure, which is directly wound by the stator coil and placed in a disc structure. Although this type of motor does not have the loss of the stator core, the stator is an air-core coil , the air gap of the motor is large, the magnetic flux leakage of the magnetic field is relatively large, and the eddy current loss of the air-core coil is relatively large, which is not conducive to designing a high-speed, high-efficiency motor
