The structure and working principle of hydraulic pumps and hydraulic motors are very similar, and some people often confuse the two. The hydraulic pump is the place where work is required to convert mechanical energy) into pressure energy, and the system that transports the pressure oil needs to do work. The hydraulic motor converts pressure energy into mechanical energy, and the pressure oil drives the blades in the hydraulic motor to rotate, thereby driving the mechanical work connected to the hydraulic motor shaft. ATO.com provides hydraulic pumps and hydraulic motors are energy conversion elements in hydraulic transmission systems. What's the difference between the two?
