Which formula calculates hydraulic motor torque?

The formula for calculating hydraulic motor torque is crucial in understanding how hydraulic systems generate and transmit force. The correct formula, which is T = (63025 x horsepower) / RPM, effectively relates torque (T) to the power output of the hydraulic motor measured in horsepower and its rotational speed in revolutions per minute (RPM).

This formula stems from the relationship between power, torque, and rotational speed. Power in hydraulic systems can be calculated using torque and rotational speed, where power (in horsepower) is equal to the torque (in foot-pounds) multiplied by the RPM, divided by a conversion factor of 5252. When rearranged, it provides the expression for torque as shown: Torque equals (Power in horsepower times 63025) divided by the RPM.

Understanding this relationship is important because it allows fluid power practitioners to quantify the performance of hydraulic motors and apply it in calculations involving machinery performance, ensuring that the system operates efficiently and effectively under various loads and speeds.
