Design of an Axial Flux Permanent Magnet Eddy Current Brake for Application on Light Weight Motor Vehicles

Abstract

Axial flux permanent magnet designs are compact and becoming an attractive design for electric vehicles as an auxiliary braking system. This work develops the design of an Axial Flux Permanent Magnet Eddy current brake for application on Light Weight Motor Vehicles as guided by industry regulations. The work makes a link between the common Finite Element Method approach used in the literature and the Analytical approach previously done. The design is conducted to meet the torque requirements per wheel. The average torque over the operating range closest to the design requirement was used as the solution.
