In many practical applications, it is necessary to stop the motor quickly than quick starting. Delay in starting a motor keeps machinery idle causing no adverse effects. But a delay in stopping a motor can cause heavy damage to equipments arid even loss of life of operator. Hence electric braking is important which stops the electric machines quickly than the mechanical brakes.
In electric braking, the stored energy in the rotating parts of an electric machine is converted into electrical energy and dissipated by the resistance in the form of heat or returned back to the supply.
