The inner rotor, typically with N teeth, meshes with the outer rotor, which has N+1 teeth. This unique epicyclic gearing arrangement creates expanding and contracting chambers as the rotors turn. In a hydraulic motor, high-pressure hydraulic fluid is directed into the expanding chambers, exerting force on the inner rotor and causing it to rotate. As the rotor turns, the chambers contract, expelling the lower-pressure fluid to the return line.
