A Continuous Toroidal Winding SRM with 6 or 12 Switch DC Converter

A new toroidally wound switched reluctance machine (TSRM) with a single continuous multi-tapped winding (CW) is presented. This machine may be driven by a 6 switch asymmetric converter which supplies uni-polar coil currents, or a 12 switch voltage source converter that supplies bi-polar coil currents. The TSRM magnetic design and power electronic control is described, and its performance is compared to a conventional switched reluctance motor (CSRM) and, to a previously reported toroidal format switched reluctance machine that utilizes 6 discrete winding (DW) coils in a 3-phase wye connection (WSRM) driven by a voltage source inverter (VSI). A fixed 6–4 CSRM magnetic circuit design is selected for comparative analysis of the three machine topologies by static and dynamic finite element simulation, the hardware of which has been validated via test data, thus forming the benchmark for this study.
