Embodiment Construction
[0025] Below in conjunction with accompanying drawing, the present invention will be further described.
[0026] The invention discloses a magnetic flux switching type permanent magnet memory motor, which comprises a stator, a rotor 2 and a non-magnetic shaft 8. The stator 1 is arranged outside the rotor 2, and the rotor 2 is fixed on the non-magnetic shaft 8. Salient pole type; stator includes stator core 1, first permanent magnet 3a, second permanent magnet 3b, three-phase armature winding 6, first pulse winding 4a and second pulse winding 4b; stator core 1 includes several stator yokes And the stator teeth protruding from the stator yoke to the center of the stator core, the stator slots are between adjacent stator teeth; the first permanent magnet 3a and the second permanent magnet 3b are embedded in the stator teeth and are separated by a certain distance, the same stator The part between the first permanent magnet 3a and the second permanent magnet 3b in the pole is the ...
