Abstract :
This paper deals with the design of a PM motor for zero-speed sensorless rotor position detection, by means of injection of a high frequency signal. Various aspects are investigated: influence of the rotor structure, stator and rotor saturation, reliability of finite element analysis to predict the motor performance, influence of rotor iron bridges and of rotor eddy currents induced. The results presented here give the key rules to design a PM motor suitable for sensorless rotor position detection.
