Abstract:
1. A centrifugal de-clutch coupled to a motor including a rotating part and stationary part, the centrifugal de-clutch comprising: a ring including an inner circumference and an outer circumference, the ring including a plurality of flexures extending circumferentially from the inner circumference of the ring in a same direction along the inner circumference of the ring, each of the plurality of flexures including a first end and a second end, the first end of each flexure extending from the inner circumference of the ring and each flexure extending circumferentially along the inner circumference of the ring from the first end of the flexure to the second end of the flexure; and a plurality of friction pads, each friction pad coupled to one of the plurality of flexures; wherein each of the plurality of flexures is configured to preload the friction pad coupled to the flexure against the stationary part of the motor to resist rotation of the rotating part below a speed threshold of the rotating part to engage the centrifugal de-clutch; and wherein each of the plurality of flexures is configured to bend outward to disengage the friction pad coupled to the flexure from the stationary part of the motor to allow the rotating part to freely rotate above the speed threshold to disengage the centrifugal de-clutch.
