Patent ID: 6869378

Claim:
A plurality of selectable and configurable driving apparatuses, with at least one driving apparatus comprising: a motor having a first output shaft; a cover; a speed reducer; and a first simple planetary roller mechanism, said first simple planetary roller mechanism including a first ring roller, a plurality of first planetary rollers, and a first sun roller, said plurality of first planetary rollers being contiguous with an inner periphery of the first ring roller, and an outer periphery of the first sun roller, wherein the cover is fixed to an output end of the motor around the first output shaft, said first simple planetary roller mechanism is coupled to an inner periphery of the cover and connected to the motor through the first sun roller, thereby forming a configurable predetermined-speed motor, and wherein a plurality of types of speed reducers are selectable and connectable to a plurality of types of first simple planetary roller mechanisms through a first carrier of the speed reducer for synchronizing a revolution component of the speed reducer with a revolution component of the plurality of first planetary rollers.
