Design and Analysis of Radial-Flux Hybrid Excitation Eddy Current Brake

Abstract

An electromagnetic design approach and performance analysis for a radial-flux eddy current brake that has hybrid excitation are presented. In this study, the brake design is done using magnetic equivalent circuit and then the eddy currents, and braking torque are calculated by numerical methods. Also, the sensitivity analysis of torque characteristics for two important parameters are performed. The presented method could be used for design and optimization of a brake for specific application.
