This paper presents dynamic characteristic analysis of permanent magnetic actuators (PMA) for driving mechanism of vacuum circuit breakers. Using coupled 3-dimensional finite element method, we calculate electromagnetic and mechanical characteristics such as currents of winding, velocity, and force...
