Hrm. AC is much more complicated than DC. EV West's graphs for their dual AC-34 motors show a nice sounding amount of power and torque. Certainly makes two (not joined) motors look like a good idea, but as you say the diff ratio isn't really high enough. If max continuous rpm is matched to top speed (say 70mph/112km/h, at 5000rmp, I get a 5.28:1 ratio diff. This will mean I get a decent speed range, and ~ 633 foot-pounds of torque at the start(?) per AC-50 motor. So 1266ft-lbs for a two motor setup.

I dunno. I picked the AC-50 because it seemed good. I'm open to other motors, of course. And I'd much rather use Paul's motor controller than the Curtis one that EV West would bundle with the motor. But that's also just a personal preference. Those controllers are $1900 each on their own O_o

This is an expensive hobby. :P
