Abstract :
This paper describes impact torque characteristics of a new electromagnetic impact mechanism employing the 3-D FEM. In this mechanism, the induced current in a coil is controlled by switching current ON/OFF depending on the rotation angle of a rotor magnet. The effectiveness of this mechanism is verified by carrying out the measurement on a prototype.
