Finite Element Analysis and Experimental Validation of Loss Reduction Strategies in Synchronous Reluctance Motors with Combined Star-Delta Winding

This paper investigates a combined star-delta winding for a synchronous reluctance motor. Finite Element Analysis shows that with this winding d- and q-axes inductances increase, which leads to a higher torque density and offers different possibilities to reduce losses. A measurement technique for loss separation to verify the theoretical findings is discussed and corresponding results are shown.
