摘要：

It is difficult to calculate the offset angle of the built-in magnetic pole in the high-speed servo motor. This paper presents a cogging torque equivalent model (CTEM) of the interior permanent magnet servo motor (IPMSM). Taking the 4-pole and 24-slot IPMSM as an example, the equivalent model implementation steps from the IPMSM to the CTEM has been introduced firstly, then the optimization method of the interior pole-shifting angle and the finite element analysis are executed to verify the equivalent model. The results show that the cogging torque of the IPMSM can be reduced by 90.1% according to the optimized equivalent angle of the CTEM, which verifies the rationality and validity of the CTEM.
