This paper studied the mathematical model of a monostable permanent magnetic actuator＇s dynamic characteristics, finishing the reduction of quality and counter-force. The dynamic behavior of the monostable permanent magnetic actuator was calculated by the finite element method. A few simulation curves such as current and position and movable contact velocity were obtained, and experiments were also carried out. In the test, the open and closing position of contacts were measured and the current parameters of the open and closing coil were also obtained. The results show that the simulation calculation is correct and reliable, and the dynamic behavior of the actuator is excellent.
