Applications of DC injection braking. When power is disconnected from the motor, the rotor spins freely until friction slows it to a stop. Large rotors and loads with a high moment of inertia may take a significant amount of time to stop through inherent friction alone. To reduce downtime, or possibly as an emergency safety feature, DC injection braking can be used to quickly stop the rotor. Speed Control of DC Motors: the speed of a motor is given by the relation 3- A dc shunt motor takes an armature current of 20 A from a 220 V supply. The excellent electric braking methods are available which eliminate the need of brake lining levers and other mechanical
