The hydraulic motor manufacturer states that hydraulic motors use fluid pressure to drive mechanical loads. Hydraulic motors cannot be used as isolation units like electric motors.
It must be part of a hydraulic circuit that includes hydraulic pumps and other hydraulic devices such as valves, filters, high pressure hoses, metal tubes, hydraulic tanks, and the like.
The pump draws hydraulic fluid from the reservoir and supplies it under pressure to a hydraulic motor that is mechanically coupled to the workload. The pump receives mechanical power through a prime mover (internal combustion engine or electric motor).
After passing through the hydraulic motor, the hydraulic fluid returns to the reservoir, is filtered and reused as needed. Hydraulic motors are fluid dynamic actuators that provide linear or rotational motion depending on their design.
They are rapidly becoming popular for a variety of technology applications. Due to their inherent advantages, they are preferably used to replace motors or systems that contain complex mechanical connections, as well as for new applications.
In the case where the motor can only provide rotational power and the size must be suitable for the load application, the hydraulic motor is much smaller in size even if the application involves heavy loads. In heavy-duty electromechanical systems, large motors need to be positioned directly on the moving shaft, which may not always be possible. It also requires continuous power supply, usually from an external source.
For the same application, a relatively small hydraulic motor can be easily placed and connected by a high pressure flexible hose arrangement to a remotely located pump within the system, which hose can even be conveniently arranged by unfavorable distortion and bending.
