Braking due to unbalanced power supply in three-phase motors

The three-phase asynchronous motor is designed to be powered by a balanced three-phase voltage system. This generates a magnetic flux of constant amplitude in the rotating stator.

DC injection braking in three-phase motors

This braking procedure is achieved by disconnecting the motor from the AC power supply and connecting two terminals of its stator to a DC power source. These remain valid.
