Torque Analysis and Dynamic Performance Improvement of a PMSM for EVs by Skew Angle Optimization
IEEE Transactions on Applied Superconductivity(2019)
摘要
In this paper, a permanent magnet synchronous machine (PMSM) for electric vehicles (EVs) is studied. Since EVs need to face some low speed road conditions, it is necessary to drive the machine to maintain a stable torque at low speed. The stator skew slot is often adopted to reduce torque ripple; however, it declines the output torque at same time. Besides, the difference between positive rotation...
