Abstract：The stator core saturation and armature reaction restrict the permanent magnet synchronous motor (PMSM) to improve the output torque, which is unable to meet the demand in some applications. In this article, the torque overload ability of PMSM was enhanced. Firstly, according to the output power of the PMSM, the contributions of phase current, d-axis reactance and no-load back EMF to the output power were analyzed. Secondly, by changing the stator and rotor structural parameters, the influence of the slot/pole combination, magnets depth, stator split-ratio and stator tooth width on the output torque was analyzed. The design method of high overload PM motor is obtained. Finally, the finite element analyses and electromagnetic design were carried out, and a PMSM with 10 times torque-overload ability was developed. With the dynamometer test platform, the resistance, inductance and torque-current curves of the high torque-overload motor and the conventional motor were tested and compared. The experimental results verified the correctness of the theory.
