The hydraulic motor converts hydraulic flow into ______.

• A. Rotary Shaft Speed
• B. Linear Displacement
• C. Negative Displacement
• D. Hydraulic Pressure

Answer: (A)

A hydraulic motor turns the energy in pressurized fluid into rotational motion. The flow rate of the fluid determines how fast the motor’s output shaft can spin—the more fluid moving through per unit time, the higher the shaft speed, up to the limits set by the motor size and the load. The pressure provides the force that creates torque, but the observable result of the motor is rotation (speed) and torque, not linear movement. A hydraulic cylinder handles linear displacement, not rotation, and “negative displacement” isn’t a relevant idea here.
