Abstract
A rapid-torque clutch/brake assembly has a hub secured to the driven shaft and connected to an axially displaceable ring by a pair of spring rings which flank interdigitating arms of the axially displaceable ring and the hub. An electromagnetic coil can be energized to selectively shift the axially displaceable ring into engagement with a clutch ring coupling the shaft to a driving element such as a pulley, or into engagement with a brake ring connected to a housing for braking rotation of the shaft.
