Abstract
A centrifugal clutch is disclosed characterized by the use of an electromagnet to disengage a driven output load from a driving input member. In the clutch assembly, a rotatable output load is disposed about a rotatable drive shaft that carries centrifugal-responsive friction shoes. The shoes contain a magnetic pole an under centrifugal force move radially outwardly during rotation of the shaft to engage frictionally the output load for common rotation. A stationary electromagnetic coil disposed between the shaft and friction shoes attracts the shoes upon energization away from the output load to interrupt the frictional drive connection.
