thanks for the reply. I'm still so far away from actually building a car it's still just a dream. Life just keeps getting in the way, but I'm thinking I may still try to get these motors anyway, if I can, since you have proven they can work. If I can get something better before I'm ready to start building something I might. My thought was to run the two together in tandem at 72 volts. Either that or find a really light car. It would complicate the build but give me twice the power. I should be able to run both motors off of one controller, I think. Kelly actually makes sepex controllers up to 144v, but I don't think those motors would take it. I know they don't have the best rep. but some guys are happy with them. So your field peaks at 50amps, what voltage are you running the field at? What gear are you in at top speed and what is your motor rpm? Hope you don't mind all the questions, but you are the guy that made it work.
