Abstract :
The development of switched reluctance (SR) technology has progressed rapidly and successfully without any detailed knowledge of inter-phase mutual inductances. The authors examine experimentally the mutually induced voltages in SR motor windings and provide a theoretical explanation for their shapes based on a lumped reluctance model for the motor. The authors focus on the mutually induced voltages in phases adjacent to the one(s) producing torque. This is only possible if the adjacent phases are not themselves used for torque production, but are temporarily disconnected from the power converter for the purpose
