Motor Speed Calculator

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
