Why is electric braking smooth and resilient?

To determine

Explain why electric braking is smooth and resilient.

Explanation of Solution

Electric braking:

Electric braking is the effective braking method that is performed by applying direct current to one or all three phases of the motor after AC voltage is removed completely. Then, there will be a stationary DC field in stator instead of rotating AC field.

When electric braking is applied to a motor, the motor is braked smoothly and quickly to a standstill. Hence, the electric braking controller provides a smoother positive stop since braking torque decreases rapidly as the speed approaches zero...
