The influence on the electromagnetic parameters , by the change of air ply , permanment magnet length and the magnetic pole arc coefficient , are calculated by the ansys software . the optimum parameter of the magnetic pole is obtained by solving the magnetic field
2.
The process of design in this paper is : lto select the stator configuration of pmsm refer to asynchronous motors whose capacity is similar to pmsm ' s . 2 . to research the no - load airgap flux distribution , so as to select the rotor configuration , which consists of some important parameters , such as the permanent magnet dimension and pole arc figuration . 3 . to calculate the important parameters x ~ and xa
