Ok got another gearbox today, a bit more robust, just a size comparison on planetary gearbox and motor along with one of our truck motors. gearbox is 4:1, 3:1, 3:1, and diff is another 3:1 reduction. Should end up around 90rpm. (Or 100) motor kv isn't an exact science) and with this gearbox I can make the last two or one stage a 4:1 if I need more reduction. I've settled on plans, rear with 3:1 differential, planetary gearbox with reduction in front of axle, two transfer gears to get driveshaft higher in frame, driveshaft to motor housed under hood. Very similar to the actual 1:1 machines.

All in my head at this point. I may start making some notes for reference[/QUOTE]


This has maybe been asked before but there did you buy those motors from?
