Abstract

In this paper, a switched reluctance motor (SRM) with an auto-transformer like winding in each phase is presented. The new winding structure allows for fast demagnetization, which enhances the machine performance at high speeds. During demagnetization, the DC bus voltage is applied across a portion of the phase winding and accordingly, a higher negative demagnetization voltage/turn is applied, which leads to an increment in the discharge rate for the phase excitation currents. The proposed concept is verified through Finite Element Analysis (FEA) circuit simulations on a case study motor. The power electronic converters that can be used with the proposed winding configuration and its associated control have been investigated.
