Man, this thread has really become a wealth of info... Matt, those links are great. I'm definitely planning on putting a belly pan (at least up front) on my truck.
Simple: Shunt Wound Motor. The controller's only load is the field coils in the traction motor. A single TO-3 high current/high voltage transistor handles the current. It's mounted on a small aluminum plate, enclosed within the larger controller enclosure. No heat sinks, cooling fans or atmospheric radiation necessary.OK Sharkey, fill me in here. HOW does your car's controller only handle 10A?
