Disclosed is a method and apparatus for detecting an excitation position of an SRM by comparison of detected currents. The method includes detecting a current by applying a first test voltage to each phase of the SRM, detecting a current by applying a second test voltage to each phase, determining an...http://www.google.fr/patents/US7279863?utm_source=gb-gplus-shareBrevet US7279863 - Method and apparatus for detecting excitation position of SRM by comparison of detected current
