Embodiment Construction
[0035] Both the stator and the rotor of the dual-channel fault-tolerant magnetic flux switching permanent magnet motor of the present invention adopt a double salient pole structure. Figure 1 shows a dual-channel fault-tolerant flux-switching permanent magnet motor with 12 poles in the stator and 10 poles in the rotor. The stator is composed of a stator core and a permanent magnet. The permanent magnet is sandwiched between the stator tooth core along the circumference. The iron core and the permanent magnet and the machine base adopt an interference fit to ensure that the position of the iron core and the permanent magnet is fixed. There are neither windings nor permanent magnets on the rotor. The stator and rotor cores are made of laminated silicon steel sheets. The permanent magnets with windings and armature teeth are combined into a whole. The permanent magnets are magnetized alternately along the tangential direction of the circumference.
