WebAn eddy current brake, also known as an induction brake, electric brake or electric retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat. … WebThe DC injection braking method applies a DC current to the AC energized stator coils. This, in turn, causes the currents to be induced in the rotor bars, which creates a braking force in the rotor. DC injection braking provides a fast stop and can hold the motor through an applied braking force after the motor has stopped.
