Hm... so that prius motor is running at a voltage WAY out of the realm of any DIY project i've ever seen. I figured they'd use a 240v motor since their pack voltage is around there. So that at least proves that stepping up is a reasonable option (so a couple batts could be used to run a 120v motor, for example). Thanks, you can google things for me any time (at work, just making short responses, limited time at home to google things, mostly just interested in the title topic, not the prius)

I have my bike set up with 33 volt lithium batteries (36 volt controller) and it goes about 24mph with that set up, 72 volt should go 50mph or so but that is scarry fast and I don't tend to take my motorcycle that fast.

Thanks a lot for that info. You think double pack voltage could double the speed, eh? I'm thinking that on a motorcycle i wouldn't be able to go as fast as your bicycle with the same power. I'm thinking that a motorcycle is done best with either 2 hub motors or a larger motor inside the frame with a chain. I'd prefer the two hub motors, but then things get complicated.

What is the wattage rating of your motor and controller?

Wait a tick... is that hub an actual 3-phase AC motor? Or is it a 3-phase BLDC motor? I was thinking Induction motor when i came up with this thread.
