An Analysis of the Effect of the Disc Geometry on the Braking Rate of a Magnetic Braking System

In many cases of the friction braking process will cause an excessive friction that leads to some problems such as thermal damages, excessive wear, and decreased brake performance. Magnetic brakes can be used as an option to conventional brakes since there isno friction between the magnet and the disc with the principle of eddy current. In this paper, experiment and simulation studies are conducted for analyzing the effect of the disc geometry to the braking rate in a magnetic brake system. Three types of brake discs geometries are used, which every disc has a different disc whole geometry and size. Furthermore, the experiment also conducted in several magnetic field values and payload conditions. Simulation using FEAsoftware is also used to validate the experimental results as well as to analysis the distribution of the magnetic field around the disc brake. The results found that geometry in a disc brake and magnetic field distribution have a major effect on the braking rate.
