In this paper, a novel permanent magnet (PM) actuator for low voltage controlled vacuum contactor is proposed. Magnetic field is analyzed using finite element method. The simulation being carried out couples the electrical circuit equation, mechanical equation and magnetic field. A prototype is manufactured and tested, which shows that the contactor equipped with the proposed PM actuator has good...
A new type of low voltage circuit breaker with permanent magnet (PM) actuator is proposed. The magnetic field is computed using finite element method (FEM) to find out the relationship among the flux linkage, displacement and different currents and these information are stored in a look-up table. The control model, which is built in Matlab, is connected with the Adams model via input and output interfaces...
This paper presents a permanent magnet actuator to substitute spring mechanic actuator of air circuit breaker. The permanent magnet actuator has only several components and has high reliability. The magnetic field of the actuator is investigated by finite element method to obtain electromagnetic force. Direct discretization method is employed to consider the effect of the PM so as to standardize the...
