Abstract

A multi-objective optimization of PMSMs (permanent-magnet synchronous machines) for electric vehicles is presented in this paper. Besides of typical KPIs (key performance indicators: e.g.: power, machine losses, torque ripple, etc.), the capability to control the PMSMs without a rotor position sensor is considered. The objectives for the self-sensing (rotor position sensorless) control capability are on the one hand to keep an adequate primary magnetic anisotropy of the machine up to the maximum torque. On the other hand, both the mean and the peak to peak values of the estimated rotor position error due to secondary magnetic anisotropies are kept small. It is shown that, the optimized design is competitive compared to an optimized design without considering the SSCC (self-sensing control capability). The good self-sensing control performance of the optimized design is confirmed by simulation results.
