Abstract：Permanent magnet synchronous reluctance motor (PMSRM) is one of the most promising motor to replace permanent magnet synchronous motor (PMSRM), the high power factor of PMSRM in whole load range must be addressed. In this paper, Power factor characteristics of PMSRM in whole load range are analyzed with improved lumped parameter method and finite element method. Three typical states of power factor characteristics are obtained: local concave state in light load range, overall droop state in light load range, and the high power factor state in whole load range, which can effectively guide the engineering design of PMSRM. Furthermore, the correctness of the analysis conclusion is verified by the prototype test of a 5.5kW PMSRM.
