- Abstract
In view of low chassis and limited space of small vehicles, this paper presents an integrated electromagnetic auxiliary disc brake device. The device is formed by an excitation winding and the main magnetic circuit, both of which are located on the structure of the conventional brake caliper. The excitation winding is powered synergistically with the antilock braking system. Based on the presented main magnetic circuit, we construct the physical model of the proposed system, analyze the working principle, electromagnetic braking power, and torque, and calculate electromagnetic braking torque with conventional algorithms. To calculate the eddy current and magnetic field distribution on the disc, using three-dimensional finite element simulation method taking full account of the penetration depth and the marginal effect, we compare the electromagnetic braking torques obtained using the conventional algorithm and finite element simulation. Results show that the braking effect is effective and obvious, especially at medium and high speeds. © 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
