Centrifugal clutches and brakes use centrifugal forces to transmit power (clutch) or to limit speed (brake). As the brakes are based on a physical principle, centrifugal clutches or brakes do not require any additional external power supply, which makes them a perfect solution for safety applications.

Centrifugal clutches and brakes consist of a driving shaft with flyweights mounted around it. Flyweights are kept on the shaft by springs, on the outer side of the flyweights there are friction pads.
