Abstract

The brake friction element (1), is when the motor is energised, pulled to the off position against a spring pressure by an electromagnet energised with the motor. When the motor is switched OFF the spring presses it into the braking position. When the motor is switched on, the friction element is moved to the OFF position by a pulse magnet which automatically switches itself OFF. It uses a lever and bar system, and the friction element is locked in the OFF position by means depending on motor current suppl. When the motor is switched OFF the locking device releases the spring pressure on the friction element.
