Abstract
Majority of braking systems work on the principle of dissipation of kinetic energy to heat energy through friction. This method has drawbacks such as wear, fading, complex actuation and maintenance requirements. A more reliable braking system that is quick in response, does not heat up excessively and is maintenance-free is needed.
This project designs an eddy-current braking system and optimizes key operational parameters. A conductive metal disc is placed in a magnetic field generated by electromagnets. As the disc rotates, eddy currents are induced, producing a magnetic field that opposes the motion and generates braking torque. The system is wear-free, less temperature-sensitive than friction brakes, offers fast and simple actuation, and has reduced sensitivity to wheel lock.
It is an excellent final-year project for Mechanical, Automobile, Production, Manufacturing and Mechatronics Engineering students, combining electromagnetism, machine design and safety principles.
