The friction and windage loss models are discussed in detail later.
The motor efficiency is discussed with the friction and windage loss models.
The mechanical losses include friction loss (WF) due to bearing friction and windage loss (WW) due to air resis tance, which is primarily caused by the cooling fan.
With this model, the friction loss is proportional to the motor frequency while the windage loss is proportional to the cube of the motor frequency (Dey et al.
Windage loss occurs when friction is created with the rotating parts of the machine and the surrounding air.
Unlike frictional loss, windage loss increases non-linearly with speed.
Windage and friction losses were segregated from the total mechanical loss after calculating the windage loss using Equation (12).

OEM specification compliance reduces windage loss
, optimizes electric generating capacity, reduces air emissions, extends equipment life and reduces contamination and corrosion for enhanced reliability.
According to Praxair, Proton's HOGEN hydrogen generators are capable of producing byproduct-free hydrogen from electricity and water as well as increasing the efficiency of a utility's electric generators by reducing windage loss
Using a patent pending process, these turnkey hydrogen generation systems can increase the efficiency of a utility's electric generators by reducing windage loss
, increasing output capacity and helping extend generator maintenance intervals, all of which can result in significant savings to the utility.
