|All about brakes machines
Rotation of a drive shaft or similar component during motor operation disengages one or more brakes machines pads from frictional engagement with a stationary part of the motor or other stationary braking surface. When the motor is de-energized, slowing shaft rotation automatically brings one or more brake pads back into frictional engagement with the braking surface. Control of the brake pads' positioning is based on balancing the centrifugal force created by shaft rotation with a biasing centripetal force. Typically, only a supplemental braking force must be applied to the motor drive shaft due to a significant amount of internal friction against unwanted drive shaft rotation when the motor is not energized.
