Embodiment Construction
[0014] Such as figure 1 As shown, the fault-tolerant single-winding bearingless permanent magnet motor of the present invention includes a stator yoke 1, an armature tooth 2, a fault-tolerant tooth 3, an armature winding 4, a permanent magnet 5, a rotating shaft 6 and a rotor core 7. The stator yoke 1 is cylindrical, made of laminated electrical silicon steel sheets, and is located at the outermost part of the entire motor; The rotor core 7 is fixed on the circumferential surface, and the rotor core 7 is coaxial with the rotating shaft 6; a plurality of permanent magnets 5 are fixed on the outer circumferential surface of the rotor core 7, and the plurality of permanent magnets 5 are all used with high coercive force and It is made of NdFeB permanent magnet material with high remanence density, is formed into a cylinder, and is uniformly distributed on the outer surface of the rotor core 7 by adopting a Halbach array structure.
