Enhancement of Conventional Braking System using Eddy Current

Brakes play vital role in stopping any mechanical system. A well known application is in automobiles. The brake is very essential part of any automobile or any moving system. So we focus on the enhancement of the brakes in this project. We reviewed the available literature thoroughly and got many ideas about fabrication and testing of Eddy current brakes and methods to enhance its effect in the application. Review of research study concluded that adhesive wear and thermal degradation are the main sources of ageing or fading of mechanical friction brakes. The braking effect get reduced due to degradation of friction surfaces which ultimately results in less braking and reduced safety. Also there are chances of leakage of brake fluid in conventional hydraulic brakes due to high stresses beard by it throughout its life. In order to overcome these limitations innovative electromagnetic brakes are developed Previous research studies give some idea about the design, size, and capacity of eddy current brakes. In present work we carried out few experiments whose data is given in the paper. The experiments include finding MI of system, design of solenoid coil, design and fabrication of a model, testing eddy current effect on model. The conclusions drawn from the experimentations are mentioned in the closure of the paper. It was concluded that Eddy current braking effect depends uponarea of solenoid coil, resistivity of disc material, angular velocity, thickness of disc, etc. It is observed that the design of solenoid coils, their radial position and the dimensions of disc play vital role in braking with eddy currents.
