Explain why there is no danger of the motor reversing after it is braked to a stop.

To determine

Explain why there is no danger in reversing of motor after it is stopped by braking.

Explanation of Solution

The electric braking is utilized frequently to stop the motor whenever the braking is needed. Electric braking provides a smooth braking action at any time by applying direct current to the motor and turning the shaft by hand. The electric braking controller provides a smoother positive stop since braking torque decreases rapidly as speed approaches zero...
