How Do Hydraulic Motors Work?

Hydraulic motors use pressurized hydraulic fluid to transfer power between pistons, turning the motor for more force and requiring less start up power. The pressurized fluid replaces gears and levers. This approach is known as mechanical replacement, and it helps to increase the start-up power of the motor.

A basic hydraulic motor contains two pistons separated by tubes that hold hydraulic fluid. When one piston moves it displaces the hydraulic fluid, which cannot be compressed. The pressure from the first piston, plus the pressure from the fluid, is transferred via the tubes to the second piston. This is what turns the motor.

All hydraulic motors have three common features:

1.   A surface area that is subject to the pressure differential
2.  A method of controlling the porting of the pressurized fluid to the surface
3.  A connection between the surface area and an output shaft

The performance of the hydraulic motor depends on:

1.  The ability of the surface to withstand force
2. Leakage characteristics
3. Efficiency of the method used to link the pressure surface to the output shaft

The performance of a hydraulic motor is measured by:

1.  Pressure Flow
2. Torque Output
3. Speed
4. Volumetric and Mechanical Efficiencies
5. Service Life
6. Physical Configuration
