Motor Speed


In order to calculate the Hydraulic Motor Speed n (rpm), you must enter the following figures:-

1) Pump Flow Q (lpm) and is the flow input to the motor from eg hydraulic power pack
2) Motor Efficiency, for hydraulic motors this is in the range 0.85-0.95.
3) Displacement Vg,, sizes for hydraulic motors  from 5cm3to 250cm3

Useful conversions factors:
1 cm3 = 0.061 cu.inch
1 Litre = 0.22 UK Gallons = 0.26 US Gallon
