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. The transient co-simulation is used to study the making process. Experiments are carried out on a prototype to validate the proposed method.
