magnetic brake

magnetic brake

A type of friction brake that automatically releases when current flows through the motor windings. As soon as current to the motor is shut off, a spring forces a stationary friction disk against a disk that rotates with the motor armature. The friction prevents the armature turning. An electromagnet pulls the stationary disk away from the rotating disk when current flows in the motor.
