Lets say that I'm building a DC motor. If I want to make it more efficient I could increase the number of windings. This actually doesn't make sense to me because if you want to double the amount of windings you need to use thinner wire so that you can fit them. So if you use wire that is twice as thin it also has twice the resistance. If you are doubling the loops you are also doubling the length of wire. So this seems to be 4x the resistance. If you have 4 times the resistance you need to double the original voltage. This works out to roughly the same power consumption, so what is the point?
Unless I'm totally miscalculating.
