What is a hydraulic motor?

The design of a hydraulic motor and a hydraulic pump are very similar. For this reason, some hydraulic pumps with fixed displacement volumes can also be supplied as hydraulic motors. A hydraulic motor works the other way round as it converts hydraulic energy into mechanical energy, resulting in a rotating shaft. It uses hydraulic pressure and flow to generate the required torque and rotation. The power produced by a hydraulic motor is determined by the flow and pressure drop of the motor.

Some pumps can be used as hydraulic motor

You can use hydraulic motors and hydraulic pumps as supplies for many applications, such as winches, crane drives, self-driven cranes, excavators, mixer and agitator drives, roll mills, and much more. The hydraulic motor must be geared to hydraulic system requirements; issues such as load, range of load, speed, and serviceability must be taken into account. There are different types of hydraulic motors, such as hydraulic gear motors, piston motors and hydraulic vane motors.

Flow and pressure equal power of the motor whereas displacement and pressure drop determine torque

The power produced by a hydraulic motor is determined by the flow and pressure drop of the motor supplies. The displacement and pressure drop of the motor determines the torque it generates. The power output is thus directly proportional to the speed. The hydraulic motors range from high-speed motors of up to 10,000 rpm to low-speed hydraulic motors with a minimum of 0.5 rpm. Low speed hydraulic motors generate large torques at low speeds. You can find both at our Parker distributor hydraulics company.
