[0002] Due to the structural characteristics of the disc motor, it is favored by the industrial motor field and the shipbuilding field. The disc motor is flat in design and flexible in layout for customers, but its power and torque cannot be further improved. Existing disc motor products are basically single motors, mainly using a double stator single rotor or a single stator double rotor structure, which makes the overall output power and torque of the existing disc motors relatively low. Therefore, some manufacturers increase the output power and torque of the disc motor by increasing the radial size. However, since the disc motor uses axial magnetic flux, it is impossible to increase the radial size all the time in order to increase the power and torque.
