Firstly,the common problems such as local electromagnetic force,electromagnetic torque computation,and field-circuit-motion directly coupled solution problems were studied. And then dynamic process including starting,losing step,reclosing and open-phase operations were analyzed with tine-stepping finite element method(FEM) and field experiments.
