Abstract

Compared with interior permanent magnet synchronous motors (IPMSMs), the conventional spoke-type permanent magnet synchronous motors (STPMSMs) have a problem of poor linearity of torque. The main reason is that the working point of PMs for STPMSMs under load drops significantly. In response to this problem, this paper proposes an improved STPMSM. The article introduces the structure of the motor in detail, and compares the difference in linearity of torque for the improved STPMSM, conventional STPMSM and IPMSM. Finite element analysis (FEA) and experimental results show that the linearity of torque under heavy load for the improved STPMSM is improved significantly, and the output capacity of torque is enhanced.
