Less-rare-earth multi-excitation-source double-stator flux-switching memory motor

The invention discloses a less-rare-earth multi-excitation-source double-stator flux-switching memory motor, which belongs to the technical field of motor body design and operating principles. Coaxial outer stators, rotors and inner stators are sleeved together in turns from outside to inside to compose the memory motor, wherein a radial air gap exists between the outer stators and the rotors, the rotors and the inner stators, the outer stators are composed of armature core teeth, fault-tolerant teeth and stator yokes, and the rotors are composed of a rotor support, a magnetic silicon steel block and a magnetic insulation block, and meanwhile, the inner stators are composed of the inner stator core and a combined permanent-magnet cell block. The double-stator structure of the motor realizes the separation of armature winding and permanent magnet and solves the problem that multiple excitation sources inside the traditional flux-switching permanent magnet motors restrain each other, thereby easily increasing motor power density and torque density. The memory motor maintains high air-gap flux density and ensures of the motor power density and the torque density, meanwhile, the consumption of rare-earth permanent-magnetic materials is effectively lowered. On the other side, the memory motor can realize flexible adjustment of a motor air-gap field and expand the range of speed operation.
