摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braking device for a hoist, said braking device comprising a braking disc and a magnetic field directed towards said braking disc, wherein said magnetic field generates a reaction force for braking the movement of the braking disc. Form. Economically compact, low-wear, low-wear, hoist-driven driver, wherein the drive includes a brake and self-locking drive that does not include braking torque and / or is highly dependent on load In order to provide a braking device for a motor, the following is proposed. That is, two magnetic poles out of the equilibrium state can be respectively moved toward the rotational direction of the braking disc 1 against the elastic force of the elastic member 6 along the predetermined path by the restricted induction by the reaction force. The radial spacing formed during the movement along the way is controlled by the elastic force of the elastic member 6 and has a predetermined size by any braking force depending on the rotational direction and the rotational speed.
