Re: 72v motor in a 60v system? Keyway VS. Spline?
Just checked out the blog. The fact that you have motor braking means cart either has an AC or Sepex system. The performance you stated going up a hill says it most likely a separately excited DC motor. That changed things a little bit but as long as you are comfortable with wiring and mechanical work what you want can be accomplished.
You're in for some work and a little more than your budget most likely to build a sepex system, especially at your voltage. I would now recommend a Curtis 1244-64xx controller, 400 amps is more than enough for your car. Call D&D and talk to Vic and tell him what you have. He can build a motor for your setup to paid with that controller that you will love. Your budget just increased by at least 1.5% though..
