N2 - In switched reluctance machine (SRM), the power density is increased by using full pitched winding instead of concentrated winding. It is reported that segmented switched reluctance machine (SSRM) using full pitched winding can give 40 - 75 % higher torque than conventional SRM for the same frame size. This increase in torque is due to the increase in aligned inductance. However, full pitch winding results in high copper loss, and high active weight. Hence, in this paper, single tooth or concentric winding to replace the full pitch winding of SSRM is proposed. In order to obtain the same flux paths as with full pitch winding, all the three phases must be excited simultaneously. The torque is produced due to changes in mutual inductance. This method of winding results in reduction of copper, and therefore, weight. With such an arrangement, one phase only requires DC supply, while other two phases must be excited with AC.
