Abstract (en)
[origin: EP0919507A2] The brake (1) ensures a brake force can be applied to the motor shaft (2) and/or a brake movement can be applied to a shaft coupled with the stepped belt. The brake moment of the operating brake can be varied at least during a time interval in the course of braking. The operating brake is preferably designed so that the brake moment is set to a predetermined starting value and then during operation of the brake increases as time progresses. The brake moment can be applied to the motor shaft by a main spring unit (13) whilst a secondary spring unit (17) is used to reduce the brake moment produced by the main spring unit. A damper (18) is connected in series with the secondary spring unit.
