That's 97% of the power applied gets turned into work. The overall efficiency of the system might be improved?(electric motors can be >>97% efficient, little to be gained there).
I know most of the motor design theory says that copper wire is better than aluminum but those theories are dealing with ground based motors where size may be more critical than weight. Has anyone done any calculating or real world experimenting to see if the reduced weight of an aluminum wound motor in an aircraft is enough to offset its other disadvantages?
