∙ 10y ago'Windage' is air resistance. So, 'windage losses' are losses sustained by the rotor in order to overcome air resistance.
'Windage' is pronounced 'wind- (as in air movement) age'.

What are the possible losses for a dc generator?
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Why friction and windage loss for an induction motor remain constant with change of stator voltage?
Because the RPM remains same
What is the important of brush in DC machine?
The slip rings are the most important brush in DC machine.
What is swinburne's test of DC shunt motor?
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
What is mechanical loss in dc machines?
Friction and windage causes mechanical loss in DC machines.
What are the possible losses for a dc generator?
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Is there any windage loss in transformer?
In this context, 'wind', in 'windage', is pronounced as 'wind' -as in 'breeze' or 'gale'. 'Windage means air-resistance, and this only applies to rotating machines, such as generators and motors, whose rotors have to overcome air-resistance (windage) as they rotate. As transformers have no moving parts, they are NOT subject to windage loss!
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
Why iron loss cald constant power loss?
How to calculate iron losses in dc machine
Why cant a machine be one hundred percent affective?
The reason why amachine cant be one hundred percent effective is as a result of losses.For Electrical machine such as alternator we have Mechanical losses(such as windage and frictional losses)and Electrical losses(such as copper loss in the rotor winding and stator winding).In Mechanical machine the main losses are windage and frictional losses.NOTE;ALL THIS LOSSES RESULT IN THE PRODUCTION OF HEAT,THUS REDUCING THE EFFICIENCY OF THE MACHINE.
Why are some parts of some dc machine laminated?
Some parts ǎ̜̣̍r̶̲̥̅̊ε̲̣̣̣̥ laminated because it reduces eddy curent loss i̶̲̥̅̊n̶̲̥̅̊ †ђξ machine
