Centrifugal brake „SUCO-ZERO“ This brake is used to bring a system quickly to a standstill if a pre-defi ned speed is exceeded.The system can then be reset manually to its original condition. A decisive advantage is the ability to function independent of an external power supply. Fig. 5 Fig. 6 Self-inducing electromagnetic clutch A belt pulley driven by an internal-com-bustion engine is fi tted with permanent magnets and serves as the rotor of a ge-nerator. The stator consists of a pack of laminations with copper windings.The electric current induced in the win-dings is fed to the coil of an electromag-netic clutch. This switches automatically at a certain speed to connect the drive to a machine (in this case via a timing-belt pulley).Where necessary, it is possible for the electromagnetic clutch to be switched on or off at any speed manually or by a con-trol system.
