Design Strategy And Performance Of Hybrid-Type Single-Phase Srms

Switched reluctance motor (SRM) is a low-cost, robust motor that is suitable for a wide range of applications. However, SRM has high torque ripple and acoustic noise, which is most apparent in the single-phase configurations. In this paper, the strategy and considerations in designing single-phase SRMs are presented. Permanent magnets (PMs) are included, making the structure hybrid. PMs help to secure the initial rotating position and act as another phase for continuous rotation. Finite element analysis (FEA) is performed to observe the characteristics of the models. Each proposed design is manufactured, and experiments were done to verify the effectiveness in practical application.
