Less rare earth hybrid excitation stator and rotor double partition adjustable magnetic flux permanent magnet motor

The invention discloses a less rare earth hybrid excitation stator and rotor double partition adjustable magnetic flux permanent magnet motor. The motor comprises an external partition stator, an external partition rotor, an intermediate partition stator, an internal partition rotor and an internal partition stator which are arranged in a partitioning way from outside to inside along a radial direction. The doubly salient intermediate partition stator is composed of a stator yoke, stator slots, stator teeth which radially and bilaterally protrude and fault tolerant teeth, wherein centralized distributed three-phase armature windings are wound on the stator teeth. Tangentially magnetized rare earth NdFeB permanent magnets are uniformly embedded in the internal partition stator along a circumferential direction. Radially magnetized AlNiCo permanent magnets are uniformly installed in the external partition stator along the circumferential direction in a surface-mounting way. Slots are reserved between the adjace
