| Abstract: | The permanent magnet synchronous motor (PMSM) for electric vehicles (EV) is studied, and the selection of performance parameters such as power, armature diameter, rotor structure and electromagnetic design method of a permanent magnet synchronous motor for electric vehicles is analyzed. Aiming at the problems of the air gap harmonic distortion rate and torque ripple of PMSM for EV, an eccentric air gap structure is proposed to improve the air gap harmonic distortion rate and torque ripple characteristics of PMSM. And speed control system of PMSM for EV is built by Maximum Torque Per Ampere (MTPA) strategy. The correctness and effectiveness of the design method and control strategy of PMSM for EV proposed in this paper are verified by AnsoftMaxwell and Matlab simulation and experiment. |
