Design & Implementation of a Contactless Electromechanical Braking System.

Abstract

This project, an Electromechanical Braking System is developed following, drivers and other road users' safety and comfort. Most of the conventional braking systems like mechanical systems, hydraulic systems, and pneumatic systems have certain limitations. In mechanical brake systems, erosion of the mechanical pads is carried out by frictional force and requires periodic replacement of the bearing. and electromechanical braking system is used to respond to stoppages or slowing down of the vehicle quickly. This braking system has also been more efficient. This project aims to create an electromechanical braking system model capable of applying brakes without any friction loss and without losing the energy supplied. It uses two electromagnets which runs by the supply of power from the Battery. Also, there is a wheel which is attached to the motor so when the power is supplied, by the help of motor the wheel rotates. We tested some performance test to verify its performance. We tested input voltage (12V DC) to the electromagnet system and the current of motor (0.4A) and the electromagnet coil (5.5A). We also tested vibration (0 mm/s) of our system. We tested the temperature of the coil (39.7 ˚C) and the braking disc (34.2˚C) of the wheel. In our system, the wheel was running at a speed of 104 RPM. When we applied electromagnet brake, the wheel stopped within 0.9 second without any heat generation at brake disc.
