  • Patent number: 5631510
    Abstract: An electric drive with brakes, in particular for hoists, lifting devices or positioning transporting systems, having a brake disk which is movable axially on a motor shaft so as to rotate therewith via a toothing. The brake disk has brake faces at both sides and can be pressed against a stationary counter-brake disk by a spring force. An electromagnetic device is provided which, when connected to current, causes the brake to be released against the spring force. The electromagnetic device has a.c. magnets and E-shaped magnet coil yokes. The counter-pole faces associated with the coil yokes are arranged at magnet yokes which can move angularly on all sides so that the counter-pole faces can be aligned at the end faces of the E-shaped magnet coil yokes located opposite thereto when current is applied to the a.c. magnet.
