Calculation and simulation analysis on starting performance of the high-voltage line-start PMSM

摘要

In this paper, the starting process of high-voltage permanent magnet synchronous motor (HV-PMSM) was calculated and analyzed by the time-stepping Finite Element Method (FEM) coupling with field and circuits. First, the mathematical model of starting process of HV-PMSM was established. Then the starting performance was analyzed by calculating the equations of transient electromagnetic field and mechanical movement equations. And by increasing the number of rotor cage bar to 18 in order to verifying accuracy of simulation. While the simulation results and the experimental results were present. The two types of data are consistent so that the method of time-stepping FEM coupling with field and circuits verified accurately when are used in calculating the starting performance of HV-PMSM.
