The Bentley site has some interesting products, I noticed a rating of 98% on the gear box and 96% on at least one of the motors.
The mention of a generator head 10" X 10" X 22" is the same size as mine.

You mentioned heat on the generator, now here is part of my mental blockage, If you consider bearing and air friction, they will produce some of that heat and the loss is not affecting the generator, it is accounted to the power that the prime mover provides.
The iron and copper losses are a product of motion induced by the prime mover, would they not fall into the same category as the bearings and air ?

Now the electric motor taking electric energy from some source is inducing it's own rotation, in this case the four sources of resistance are a loss that is taken out of the power delivered by the motor. This is to me what makes the 96% efficiency claimed by Bentley, a little bit suspect.????
