DESIGN AND FABRICATION OF ELECTROMAGNETIC BRAKING SYSTEM

Abstract

An electromagnetic brake is a new and revolutionary concept. These are totally friction less. Electromagnetic brakes are the
brakes working on the electric power & magnetic power. An Electromagnetic Braking system uses Magnetic force to engage the
brake, but the power required for braking is transmitted manually. Electromagnetic braking system is a modern technology braking
system used in light motor & heavy motor vehicles. This system is a combination of electro-mechanical concepts. The frequency of
accidents is now-a-days increasing due to inefficient braking system. It is apparent that the electromagnetic brake is an
essential complement to the safe braking of heavy vehicles. It aims to minimize the brake failure to avoid the road accidents.
It also reduces the maintenance of braking system. An advantage of this system is that it can be used on any vehicle with minor
modifications to the transmission and electrical systems. An Electromagnetic Braking system uses Magnetic force to engage
the brake, but the power required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet
is mounted on the frame .When electricity is applied to the coil a magnetic field is developed across the armature because of
the current flowing across the coil and causes armature to get attracted towards the coil. As a result, it develops a torque and
eventually the vehicle comes to rest. These brakes can be incorporated in heavy vehicles as an auxiliary brake. The electromagnetic
brakes can be used in commercial vehicles by controlling the current supplied to produce the magnetic flux. Making some improvements
in the brakes it can be used in automobiles in future.
