    Hydraulic motors are rotary actuators that convert hydraulic pressure supplied by the hydraulic pump into mechanical energy (such as torque and speed) applied to its output shaft. In terms of energy conversion, hydraulic pumps are interchangeable with hydraulic motors when pouring fluid into a hy...Read more »

    The world of hydraulic motors is vast with numerous motor types available for various applications. To qualify as a hydraulic motor, a motor must utilize incompressible fluid to convert hydraulic pressure into torque and rotation. In applications that require low speeds (generally less than 1000 ...Read more »

    Using mechanical energy produced by a machine’s engine, a hydraulic pump can move hydraulic fluid from the pump’s own reservoir to a connected hydraulic motor, converting the mechanical energy to hydraulic energy. The incoming fluid/energy triggers the hydraulic motor to begin rotation, which can...Read more »
