Energetic Pulley: The “input” pulley in a dual-pulley technique. The shaft of this pulley is pushed by anything like a motor, a crank, or maybe one more pulley in bigger techniques. This pulley controls the motion of the belt.
Roller: A regular pulley has a slot for a belt, chain or cable. A reel is a wider pulley generally utilized in cable systems, making it possible for the cable to be wound around many times the diameter of the reel.
