I can't help with the more electronical questions posed here, but a minor point - the original Leopard motor is not series wound. It's a compound wound. Not sure if that's pertinent to the discussion. Also, I've never heard of anyone with an electric motor with a manual transmission or direct drive that chooses to use the clutch. That's generally considered an awkward work-around for a problem that should be fixed. As for Cor's suggestion of using a microwave transformer core to make an inductor, my township's municipal services yard has an area where residents can drop off old appliances. There are almost always several discarded microwaves there that haven't been hauled away yet. Chris -------------- next part -------------- An HTML attachment was scrubbed...
