Structure design and nonlinear analysis of synchronous reluctance motor

Aiming at the problem of multiple parameters and time-consuming design, the 36-slot 4-pole synchronous reluctance motor was designed by orthogonal experimental design method. The torque performance of synchronous reluctance motor were analyzed by analyzing the effects of slot and pole fit, the number of flux layers, the thickness of the flux layer and the deflection angle of the flux layer. The structural parameters of synchronous reluctance motor were designed. It is proved that the orthogonal experimental design method can improve the design efficiency of synchronous reluctance motor through the finite element simulation, and the designed motor has better performance. By analyzing the inductance and torque performance under different current, the strong coupling and nonlinear characteristics of synchronous reluctance motor are verified.
