Also I think I misspoke about the E20 motor. I was thinking of the snowblower motor when I described it as mostly series with a bit of shunt. Of course the E20 is a separate field - how else would you be able to do field-weakening?
Thanks Robert and Jeff for the added info. I'm starting to get excited about this project!
