The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator . Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower--namely, water engines and water motors--but in today's terminology the name usually refers more specifically to motors that use hydraulic fluid as part of closed hydraulic circuits in modern hydraulic machinery . </P> <P> Conceptually, a hydraulic motor should be interchangeable with a hydraulic pump because it performs the opposite function - similar to the way a DC electric motor is theoretically interchangeable with a DC electrical generator . However, most hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven . Also, a hydraulic motor is usually designed for working pressure at both sides of the motor . </P> <P> Hydraulic pumps, motors, and cylinders can be combined into hydraulic drive systems . One or more hydraulic pumps, coupled to one or more hydraulic motors, constitute a hydraulic transmission . </P>
