Abstract
Three kinds of structure of permanent magnetic actuator (PMA) are presented in this paper and the finite element method(FEM)is adopted to calculate the magnetic field. The calculation results are analyzed and the PMA configurations are compared. Besides
the PMA dynamic behavior is simulated. It is proved that the results with direct coupled method may meet the requirement of engineering design.
