Electromagnetic actuators are widely used for various electronic instruments. To determine the optimum design for actuators, it is necessary to analyze their dynamic characteristics accurately. This paper describes a method that uses the 3-D finite element method to analyze the dynamic characteristics of an actuator taking account of the motion of the armature. The method was used to obtain the dynamic characteristics of a linear solenoid actuator, the induced voltage characteristics of a permanent magnet motor taking account of the magnetizing process, the dynamic characteristics of a stepping motor for a wristwatch, and the dynamic characteristics of a claw-poled stepping motor. The validity of the 3-D method is confirmed by the results of the experiments for each model.
