Parametric analysis of eddy-current brake performance by 3-D finite-element analysis

Eddy-current brakes as primary brakes in automobiles can potentially remedy the problems posed by conventional friction brakes. First, however, it will be necessary to analyze the effece of each design parameter on the performance of the eddy-current brake before designing a conceptual brake for a practical application and evaluating its behavior in real-life driving situations. In this paper, we analyze the effects of design parameters on the torque-speed curve of the eddy-current brake by the means of three-dimensional (2-D) finite-element analysis. The paper follows a previous work in which analysis was performed with a 2-D analytical model.
