Summary:Position sensorless control of PMSMs is one of the important research object in terms of lowering cost, saving installation space and improvement of reliability. A previous research proposed a method to estimate EEMF(Extended Electromotive Force) excited by signal injection and speed for all speed range and confirmed its performance in EV. In this paper, position sensorless control including overmodulation is implemented to EV and evaluated its performance.
