Abstract

Vehicle generally require an optimal braking system, eddy current brake (ECB) can be used as an alternative to the conventional braking system. Unipolar Axial ECB was discussed in this paper. Performance of ECB is influenced by several factors, like the distance of the pole location to center of the shaft. The pole location determine the braking torque because the change of braking force arm. In this paper, finite element method (FEM) based modeling are used to describe the eddy current change. Size and design of ECB are based on a conventional hydraulic braking system. The standard pole location will be similar to the brake pad on a conventional hydraulic braking system. The pole location will be varied to profile the changes in braking torque. From data, it was found that the pole location near than standard tends to have good braking torque at high speeds. In reverse, at low speeds it has lower braking torque compared to standard pole location. Then at the pole location far than standard give the resulting braking torque is lower in both while low speed and high speed. It is because the eddy current turn path area become narrow on the rotor when the pole location far from standard.
