Ah, gearing is nice, didn't know it was that sort of budget
fyi, saw this vid and thought I'd put it here. The 123kw mg2 on the highlander looks pretty much the same as the 47kw mg2 in the prius (or the mgr).
but the additional planetary set allows it to spin to 14000 rpm. Which requires high voltage (or lower voltage requirements/higher amps). Napkin guess says triple the turns in hand, third the number of turns, and throw 220v @ 600A at the mgr and see if just one mgr makes 125kw
(or sort out 650v@200a) and increase the gear ratio accordingly (or put go-kart wheels on it), and wonder why they didn't add the extra rpm drop to the mgr.
of course if mg1 is putting out more like 800v then adjustments will be necessary.
If you can approach your power goals with half the motor weight, that would be good. What is different about the highlander mg2 vs the mgr besides gearing?
anyway, I'm eyeing some toyota parts for the bike.
