Abstract

The invention discloses a dual-channel switched reluctance fault-tolerant motor which comprises an outer stator iron core (1), a rotor iron core (3) and an inner stator iron core (6) which are concentrically nested, main winding poles (2) protruding inwards are arranged on the circumferential inner wall of the outer stator iron core (1) at equal intervals, and each main winding pole (2) is provided with a set of main winding (8). Rotor inner salient poles (5) and rotor outer salient poles (4) which are not provided with windings are arranged on the inner wall and the outer wall of the circumference of the rotor iron core (3) at equal intervals respectively, secondary winding poles (7) protruding outwards are arranged on the outer wall of the circumference of the inner stator iron core (6) at equal intervals, and each secondary winding pole (7) is provided with a set of secondary windings (9). The pole arc width of the rotor outer salient poles (4) is equal to the pole arc width of the main winding poles (3), and the pole arc width of the rotor inner salient poles (5) is equal to the pole arc width of the secondary winding poles (7). The structure is simple and compact, and the reliability and fault tolerance of motor operation can be improved.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a dual-channel magnetic levitation switch reluctance fault-tolerant motor capable of dual-channel operation and improving the reliability and fault tolerance of the motor operation. Background technique [0002] The switched reluctance motor originated in the United Kingdom and has two basic characteristics: one is switching, that is, the motor must work in a continuous switching mode state, which is only after the development of various new power semiconductor devices. The main reason for the development; the second is reluctance, which is a real reluctance motor, the stator and rotor are salient pole structures, and have a variable reluctance circuit. [0003] Switched reluctance motors rely on the reluctance torque generated by the change of winding self-inductance to drive the rotor. Switched reluctance motors have the advantages of simple manufacture, low cost, firm structur...
