Abstract :
Stepping motors are widely used for various electric instruments. It is necessary for the optimum design to analyze the dynamic characteristics accurately. Our method, which is the 3-D finite element method with edge elements taking into account the rotation of the armature, has been expanded to analyze the dynamic characteristics of a stepping motor for a wristwatch excited from square pulse voltage source. The validity of our method is confirmed by experiments
