Transient Torque Analysis of Electromagnetic Impact Drive Mechanism Taking Into Account Motion Equation

摘要

This paper presents a transient torque analysis method of an electromagnetic impact (EMI) drive mechanism by 3-D finite element method (FEM). The transient torque is computed by coupling with motion analysis when the ring magnet rapidly passes through conductors and magnetic poles. The effect of rotation speed of magnet on the transient torque is clarified.
