Abstract
The utility model discloses a mixed excitation doubly salient permanent magnet motor. The motor comprises an electrical excitation winding, permanent magnets, a rotor, phase windings, a stator yoke part and a stator inner iron core. The permanent magnets are arranged on the inner surface of the stator yoke, and the electrical excitation winding is arranged between the permanent magnets and is placed on the inner surface of the stator yoke. The stator inner iron core is disposed on the inner surfaces of the permanent magnets, and the phase windings are disposed between the rotor and the stator inner iron core. The motor mixes the electrical excitation winding and the permanent magnets, so that the motor is simple and firm in structure, can be cooled easily, and can achieve double current coordination control and online efficiency optimization.
