| Abstract: | By using the function of Maxwell two-dimensional transient electromagnetism, the no-load and load performances of PMSM with some sudden short-circuit are simulated. In the moment of maximum short-circuit current of permanent magnet, demagnetization degree is analyzed, Which provides a theoretical basis for the demagnetization of PMSM. |
