Design of a Non-contact Electromagnetic Impact Mechanism

Abstract

We have proposed a non-contact electromagnetic impact-torque mechanism (EMI mechanism) using induced current, and its characteristics have been verified by using 3-D finite element method (FEM) analysis and carrying out measurements on a prototype. This paper describes an optimization method of the parameters of the electromagnetic impact system - such as dimension and number of poles - using the Design of Experiments (DOE) method. From this result, we can obtain a design guide for constructing an efficient EMI mechanism by using the DOE method.
