Abstract :
A method for the sensorless control of a switched reluctance motor (SRM) at standstill is presented in this paper. At standstill, each SRM phase is excited in sequence with a narrow voltage pulse. The most suitable phase to be excited first for starting the SRM can be detected by comparing the amplitudes of the resultant phase currents. Other sensorless control techniques, such as AM method, can be adopted to control the SRM during running conditions. Simulation and experimental results are presented to verify the proposed method
