Problems solved by technology

[0002] Existing motors or generators are mainly composed of a stator and a rotor. The rotor windings or the stator windings are energized to generate a magnetic field. The rotor and the stator rotate under the interaction force of their respective magnetic fields, thereby converting electrical energy into mechanical energy or mechanical energy into electrical energy. The magnetic poles of the motor and motor of this structure are respectively arranged on the stator and the rotor, and the interacting magnetic poles mainly overlap in the radial direction of the rotor, so that the torque of the magnetic field force of the interacting magnetic poles (windings) is relatively small, so that the motor or The generator is in a high-efficiency working range, the range is narrow, the transmission torque is low, the power density ratio is low, and the volume is large
