I was wondering about the windings of the stationary coil on pre post war motors. I have had a couple of motors that I have put together from yard sales that the PO has unwound a few of the turns(the last one at least eight). How does this affect the running of the motor. This last one I just hooked it up, cleaned it, put new brushes in and tested it. I put it on the test stand and let it run for an hour and it didn't seem to have any effect. It ran fine, didn't get hot granted it was just free running no weight but it seemed fine. Any thoughts?
