Abstract
Single-layer winding configuration in a 12-slot 10-pole Permanent Magnet Synchronous Motor (PMSM) has been adopting in electrical power steering (EPS) systems to get the high fault tolerance capability of the motor. However, the motor with single-layer winding has magnetic circuit saturations in the teeth, which deteriorates its performance. In this paper, we propose asymmetric teeth widths to get over the demerit, and analyze the effect of the teeth width ratio variations on the performances of the PMSM. As a result, we suggest the most valuable teeth width ratio for designing the PMSM with a single-layer winding configuration.
