Abstract

PMSM is a heated research field in terms of the HEVs. In order to increase the efficiency and output characteristics of the PMSM, the design and modeling method which can design the PMSM according to its performance requirements is necessary. In this paper, a new modeling method for multi-field coupling dynamic analysis for PMSMs based on forward design theory is proposed and verified. In particular, given some performance parameters, stator and rotor structural parameters can be decided by electromagnetic load prefetching algorithm and maximum torque method. Besides, the mathematical model of the PMSM power losses achieves an evaluation of the motor output performance effectively. Simulation results compared with the PMSM experimental data show the proposed approach is valid.
