Abstract

An optimal permanent magnet synchronous motor (PMSM) should be a low cogging torque and a sinusoidal back-EMF. In this paper, different magnetizations and shaping models of permanent magnets (PMs) are investigated for achieving an optimal performance. The technique of slot opening shift is simultaneously implemented on the stator slots for more reducing of the cogging torque. To this end, the conformal mapping (CM) method as an accurate and fast technique is used to calculate the motor performance under each condition. In final, the optimal results obtained through the CM method are verified by comparing with the corresponding results obtained from the finite element method (FEM).
