Worried about the direction of rotation of the dynamo I mentioned in the Maytag thread, I had a look at it and there appears to be nothing to indicate which way it ought to go. It is a two pole machine with fixed brushes on the neutral axis between the main field poles, on which basis it should be equally happy in either direction. There are however two smaller interpoles in line with the brushes, I believe these assist spark free commutation - does their wiring determine the correct rotation?
