【Abstract】 This static character of electromagnetic field of an electromagnetic actuator used on AC contactor was analyzed by 3D finite element method. On the base of it,the paper uses the “virtual model” technique and presents the optimization design method of the AC contactor’s characters. At last the characters of old model were compared with that of the new one.更多还原
