Motors • Hydraulic Motors

Used to convert hydraulic pressure and flow into torque and angular rotation. Interchangeable with hydraulic pumps.

Considered more efficient than electrical motors or pneumatic motors, hydraulic motors convert flow and hydraulic pressure (hydraulic energy) into continuous rotation and flow (mechanical energy).Commonly found within construction and agriculture equipment, hydraulic motors are found in winches, crane drives, self-driven cranes, excavators, conveyor and feeder drives, mixer and agitator drives, roll mills, drum drives, kilns, shredders, drilling rigs and trench cutters.Three primary types of hydraulic motors exist: gear and vane motors, axial piston motors, and radial piston motors.Gear and vane motors are used in basic rotating systems, and feature low initial cost and high rpm. Axial piston motors are commonly used in hydraulic systems, while radial piston motors are available in two types: crankshaft and multi-lobe.
