DC injection braking is a method of slowing AC electric motors. A DC voltage is injected into the winding of the AC motor after the AC voltage is disconnected, providing braking force to the rotor.

28 Jan 2010 I've built a few of these. The simplest system is to add an off-delay timer to the 'run' contactor and a 'brake' contactor mechanically interlocked to the 'run' one. The coil on 'brake' connects via a normally closed contact on 'run' and a normally open on the timer. That setup brings the brake contactor in for a

DC Injection Braking is a braking system used with 3-phase motors. The VFD outputs a DC current that gets applied to two of the windings of the motor, which causes the motor to quickly brake. DC injection braking really is only effective at low speeds (less than 8 Hz). DC Injection can also be used to preheat the motor, and

This is very different to the DC injection braking typically used in drives. In the DC injection method DC current is injected to the motor so that control of the motor flux is lost during braking. The flux braking method based on DTC enables the motor to shift quickly from braking to motoring power when requested. In flux braking
