How do you calculate hydraulic motor speed?
To find the output speed of a hydraulic motor, use the
Output RPM = (231 x Flow Rate) / Motor Displacement
Flow Rate = Rate of flow into motor in Gallons Per Minute (GPM)
Motor Displacement = Cubic Inches per Revolution
Example: The output speed of a motor with 25 GPM flow rate and
2.75 cubic inches of displacement is:
Speed (RPM) = (231 x 25) / 2.75
Calculated out this gives an output speed of 2100
