Abstract

In order to improve the power density and torque density of the fault tolerant permanent magnet vernier rim driven machine, a new type of fault tolerant dual-permanent magnet excited vernier rim driven machine is proposed. Permanent magnets are placed on the stator and rotor of the machine, and more working harmonics are modulated by the dual-modulation effect of the air gap permeability by the teeth of the stator and rotor, thus improving the output performance of the machine. Aiming at the problem of more optimization parameters, a new optimization design method combining multi-objective genetic algorithm with single parameter scanning algorithm is proposed to optimize the design of machine. Compared with the traditional fault tolerant permanent magnet vernier rim driven machine, it shows that the machine has better output performance.
