Abstract

This paper describes the performances of eddy current brake according to the design parameters. The characteristics are analyzed by using 2-dimensional Finite Element Method (2-D FEM) in order to predict the effect of the design parameters. The magnet stack width is determined from equivalent stack width that is calculated by solution of the field with scalar potential. The validity of available calculation program with FEM is achieved by comparing with experimental value. From the results, the optimized magnet configuration of the eddy current braking system is designed to obtain not only the maximum braking force but also the minimum attraction force
