I think that the universal motors wold probably work better on a chopped DC than they do on AC. They are shunt-wound (or so I understand) and that is what makes them "universal" as the field reverses when the armature does on the negative half-cycle, so the commutation still works. I agree that it would probably be best to take the internal electronics out of the equation. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
