Feb 08, 2010 · Gear Box Efficiency • New, large (100 kW) gearboxes may have efficiencies of 90% to 93%. Efficiency declines with age. • The number of stages of RPM reduction impact efficiency. Most aerator gear boxes have two or three stages • Small gearboxes have much lower efficiencies and combined motor-gearbox efficiency for 20 kW devices may be 80%
