Abstract
Inductance is an important parameter of PMSM due to its direct impact on the dynamic performance, especially on the precise control of the system. In this paper, an improved calculation method for the incremental inductance of motor winding is adopted, and a data processing technique is presented. Nonlinear incremental inductance of the motor winding was tested with the dynamic hysteresis loop method. The validity of the parameters FEM simulation results was confirmed by the measuring method. Accordingly, a mathematical model of nonlinear incremental inductance of SPMSM was built which provides a practical gist to determine uncertainty range of inductance parameter.
