In recent years, high speeds have been required to reduce the size of motors, but motors driven at high speeds are prone to increased losses. Among others, the generation of cogging torque due to spatial harmonics and the reduction in efficiency due to heat generation are considered. Therefore, this study proposes an interior-winding synchronous motor (IWSM) with a magnetic composite ring in the stator to suppress spatial harmonics. The efficiency of this IWSM is 7.3% higher than that of conventional motors.
