Switched reluctance machines (SRMs) have been comprehensively researched, and they play an important role in the modern industrial field. The topology of SRMs is quite simple and only one set of windings is employed. Consequently, the winding configuration has an essential impact on performance. In this paper, a new winding configuration for SRMs with only half-teeth wound (HT-SRM) is proposed, which is totally different from the conventional SRMs with full-teeth wound (FT-SRM). First, the basic topology and operating principle of HT-SRMs are presented by a three-phase 12/8 prototype. Then, based on the 2-D finite element analysis, an optimization of the original 12/8 HT-SRM is conducted and a series of static characteristics of three SRMs, namely, a conventional 12/8 FT-SRM, an original 12/8 HT-SRM with the same iron laminations, and an optimal HT-SRM with the optimized dimensions, are compared. Finally, three 12/8 SRM prototypes are fabricated and the experimental results verify the theoretical analysis and the corresponding finite element analysis-based predictions.
