Example Embodiment
[0042] A new type of high torque density and high power factor fault-tolerant permanent magnet vernier motor of the present invention includes an inner stator 1, an inner rotor 2 and an outer rotor 3 from the inside to the outside, between the inner stator 1 and the inner rotor 2, and the inner rotor 2 and the outer rotor 3 are both left with an air gap; the inner rotor 2 is embedded with radial permanent magnets 4, using tangential excitation, the N poles and S poles of the radial permanent magnets 4 are alternately arranged along the circumference; the inner rotor 2 A number of surface-embedded permanent magnets 5 are embedded between the outer rotor 3 and the outer rotor 3. The surface-embedded permanent magnets 5 are unipolar, and they are all excited in the direction of the center of the circle; the inner stator 1 is alternately arranged with armature teeth 6 and fault-tolerant tooth 7; the armature tooth 6 and the fault-tolerant tooth 7 are evenly arranged with equal-sized...
