ELEVATOR BRAKE AND HOISTING MACHINE

摘要

The invention relates to a brake (94) and a hoisting machine for an elevator. The brakes of the hoisting machine comprise a brake frame (14), an electromagnet consisting of a coil (15) and a magnet body (4) and a moving frame (9) with a brake shoe (95) secured to it. In the brake, the thermal conductivity of the material of the brake frame (14) is better than the thermal conductivity of the material of the magnet body (4).
