Braking systems in motor vehicles generally use a braking system that utilizes friction. The braking performance will decrease caused by using friction rapidly. To overcome this, as an alternative, an electromagnetic braking system can be used by utilizing eddy currents, such as eddy current brakes (ECB). Eddy currents are generated when the rotor pass the magnetic field of the electromagnet. The research aim is to design an ECB system. The performance of the disk design will be determined in this study. The study is about the tendency of the ECB properties. The finite element (FEM) method is used by modeling ECB performance. The experimental results were used to validate the result. The test showed the results of braking using aluminum disk showed the best performance in 12.03 Nm. From these results, the combination of the disks is needed by an appropriate disk design.

Distributions of normal stress, shear stress, and coefficient of friction were determined at the interface between a steel tool and a plastically deforming aluminum disk, using two pressure-sensitive pins imbedded in the tool. Comparisons were made with the normal-stress predictions of plasticity analyses, assuming constant shear stress or friction coefficient across the interface. Agreement was improved by considering actual variations in shear stress from lubricant-film deterioration but interesting and unpredicted features were still encountered. The course of liquid-lubricant breakdown was modified significantly by compression with periodic cycles of loading and unloading which resulted in lower friction stress for reactive lubricants, such as fatty acids, and in higher friction stress for inert lubricants, such as mineral oil.
