Abstract

The combination of high stator currents and rotor temperatures in PMSMs can lead to PM edge demagnetization (ED). This will produce a torque derating as well as a displacement of the rotor magnetic dq- axes. Under these circumstances, optimized torque trajectories, e.g., maximum-torque-per-ampere (MTPA), maximum-torque-per-voltage (MTPV) or maximum-torque-per-flux (MTPF), can be altered. This paper analyzes the effects of edge demagnetization on torque production capability and control performance. The use of a search coil (SC) is proposed for on-line edge demagnetization detection and control reconfiguration.
