Abstract
A centrifugally triggered brake mechanism is used to halt a rotating assembly. The brake mechanism includes a braking surface, a brake shoe, and a rotating centrifugal trigger. Upon attaining a selected rotational speed the trigger releases the brake pad to engage the drum. The mechanism may be useful for instance in providing backup overspeed protection for wind turbines.
