Intelligent Electromagnetic Braking System

Abstract

Abstract

The principle of conventional braking system involves the conversion of kinetic energy into heat. It uses development of contact friction for retardation. When the brake is applied, the brake shoes having a friction material lining are forced by hydraulic wheel cylinders against the inner surface of a rotating drum. The result of this contact produces friction, enabling the vehicle to slow down and stop. The design consideration is such that the heat dissipated is less. But the heat cannot be avoided but only be reduced. To avoid the heat phenomenon, electromagnetic braking system can be used which is contactless system and can provide better response time and in general to keep the whole braking system work longer and safer. Being electrically operated there is very less time-lag between the application of the brake pedal and the wheels as compared to other systems. In contactless braking system, there is elimination of wheel drum, brake shoes, brake pads and lubrication. Using a disk plate and electromagnetic coils which generates electromagnetic force to stop the rotations of the disk without contact (also known as Eddy currents). Using IR sensor mounted on the vehicle improves the safety and making it more prevalent.
