Electric braking performance analysis of PMSM for electric vehicle applications

Abstract

This paper analyzed the performances of plug braking and regenerative braking of Permanent Magnet Synchronous Motor (PMSM), which is often used as the driving motor of electric vehicles. The electric braking principles are briefly explained at first. The performance analysis focuses on maximum braking torque, braking torque ripple and the feedback power of braking energy. The two main control methods for PMSM, six step commutation control and field oriented control (FOC), have been analyzed. A simulation system has also been developed in this paper and the analysis is supported by the results of simulation and preliminary experiments.
