Hydraulic motors are used in any application requiring rotational force, also known as torque. A hydraulic engine converts hydrostatic energy into mechanical energy by pushing vanes, gears or pistons mounted on a crankshaft.

Hydraulic motors are utilized for many applications now such as winches and crane drives, wheel motors for military vehicles, self-driven cranes, excavators, conveyor and feeder drives, cooling fan drives, mixer and agitator drives, roll mills, drum drives for digesters, trommels and kilns, shredders, drilling rigs, trench

Hydraulic motors are rotary actuators that convert hydraulic, or liquid energy into mechanical power. They work in tandem with a hydraulic pump, which converts mechanical power into fluid, or hydraulic power. … Fixed-displacement motors drive a load at a continuous speed while a constant input circulation is provided.
