Hydraulic motors transform hydraulic flow into rotating speed and hydraulic pressure into mechanical torque. Motor rotating speed is proportional to the flow which is supplied to it. Torque produced is proportional to the hydraulic pressure the motor receives.
Typical applications are those requiring high torque within a small size. The hydraulic motor is essential for rotations where:
- mechanical solutions are complex or even impossible,
- electrical or pneumatic power sources are not available,
- environments are dangerous (i.e. risk of explosion or extreme temperatures).
