This paper introduces a promising technique for detecting the rotor position of a PM motor at standstill. The technique is based on the B-H hysteresis characteristics of the stator iron. Depending on the rotor position, a very particular phenomenon related to B-H hysteresis appears. This phenomenon permits to detect the electrical position of a non-salient rotor.
