WebFigure 2: DC Injection Braking Motor Current Waveform Note that DC injection braking always requires a power source. Therefore, it is not always a viable option for safety reasons when applications require a fail-safe braking mechanism. DC injection braking energy is dissipated by the control and motor in the form of heat. 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…
