Which device is used to convert hydraulic power into rotary mechanical motion in a hydraulic system?

• A. Hydraulic Pumps
• B. Hydraulic Motors
• C. Cylinders
• D. Accumulator

Answer: (B)

Hydraulic power is converted into rotary motion by a hydraulic motor. In a hydraulic system, a pump pressurizes fluid and creates flow, while the motor uses that pressurized fluid to produce torque and turn the output shaft. This rotary conversion is the motor’s primary function. Cylinders, in contrast, convert hydraulic energy into linear motion by extending or retracting a rod. An accumulator stores energy as pressurized fluid but doesn’t directly generate motion. So the device that transforms hydraulic power into rotational work is the hydraulic motor.
