Abstract :
This paper presents a computation method for analyzing the impact torque characteristics of a new noncontact electromagnetic impact mechanism employing our 3-D FEM code. In this method, magnetic field analysis is coupled with electric circuit analysis and motion analysis. The operating principle of this mechanism is described, and torque performances are shown. The validity of the analysis is verified by carrying out the measurement on a prototype.
