This paper aims at studying the energy distribution in each subsystem during the closing process based on the equivalent electrical and mechanical models of contactor. On one hand, the more dynamic behaviors are related to contactor can be obtained; on the other hand, the end result is helpful to improve the performance of contactor. Based on easy modeling and high calculating efficiency, the magnetic circuit analysis method is adopted as the establishing approach of contactor model. The simulation model of contactor is implemented by using Matlab/Simulink software tool. The simulation results showed that the energy distribution in each subsystem critically depends on the initial phase angle of ac voltage source. If the contactor is supplied to some ac voltage source at a specified initial voltage phase angle, the moving velocity or kinetic energy of movable contact prior to collision is allowed to be effectively controlled. Therefore, the rebounding time of contacts after the first time close with fixed contact can then be reduced greatly.
