WebAn advantage of using DC injection braking is that you can control the amount of braking torque Spring-engaged, electrically- released Which of the following statements best … 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 internal friction alone. To reduce downtime, or possibly as an emergency safety feature, DC injection braking can be used to quickly stop the rotor. A DC injection brake system can be used as an alternative to a friction brake system. DC injecti…
