How Do Hydraulic Motors Work?

Hydraulic motors work by channeling the power generated from fluid pressure to move mechanical loads. Unlike an electric motor, a hydraulic motor cannot run as a separate unit.

Hydraulic motors convert pressure from fluids (gases and liquids) into forces like torque and angular displacement. A hydraulic motor is typically the rotary part of a hydraulic machine and works in sync with the hydraulic cylinder.

A hydraulic pump connected to the motor channels fluid from a reservoir into pressurized tubes with the help of a combustion process. As the fluid flows through the tubes, the motor turns, and the used fluid returns to the reservoir to be filtered. The cycle repeats so that the motor keeps running.

Hydraulic motors come in a variety of types, and many applications that use these motors have been made. Regardless of the type of hydraulic motor, they all perform the same basic function, which is to actuate fluid power and deliver liner or rotary motion depending on the design.

Due to the inherent benefits of hydraulic motors, they are becoming more popular than electric motors. Some common applications of hydraulic motors include cranes, excavators, roll mills, conveyor drives, drilling rigs, trench cutters and car shredders.
