Performance:

The brake, mounted on a shaft, starts to brake a drive shaft at a defined speed. Centrifugal force causes the flyweights to lift from the hub so that their linings contact the inside diameter of the brake drum. This action creates a braking torque.

As soon as the speed of rotation of the system falls, the tension springs return the flyweights to their initial position. It is a fundamental principle of centrifugal brakes that they cannot brake a system to a standstill, i.e. the system speed searches for an equilibrium condition between the speed determined by load torque and braking torque.
