【Abstract】 A high-power DC contactor with double windings in series and the equivalence of the double-winding structure were introduced.The dynamic model of the contactor was built with the help of FLUX 3D based on FEM and multi-object dynamic simulation software ADAMS while Simulink was employed to combine the electromagnetic and mechanic system.The accuracy and efficiency of this method made it possible to optimize the electromagnetic system of contactors.更多还原
