An electronic motor braking device works on the principle of feeding direct current into the stator winding of three-phase induction motors. This generates a standing magnetic field which inhibits the movement of the squirrel-cage rotor. The braking effect depends on the size of the braking current. This is generated by rectifying the supply voltage. The use of thyristors with phase control allows the braking torque to be set over a wide range. DC braking causes a heating up of the motor.
In soft start and braking units or combi units, soft start and DC braking are represented in one unit. This enables very compact, universally applicable solutions.
