As background I’m converting my old Jeep Ute, aiming for around 100kW with a max RPM at about 4000RPM. Peak torque should hopefully be up around 850Nm at low RPM, which allows me to ditch the gearbox entirely and just run the TC.
I used to think that torque converters with their ≈2:1 torque multiplication were ideal for EV conversions, but there was some hitch that made them tricky; sadly I can't recall what that is right now.
There is a very large old topic on this, starting 2008: AC motors, multipoles, torque.I’ve found EV specific motors that meet these specs, intended for small busses and trucks, but cost and availability is prohibitive, which brought me to looking at rewinding industrial motors.
From what I can gather on forums, a 160 frame motor sounds like it may be suitable,
Weber managed to find an ABB 132 frame motor that is capable of 100 kW peak for his MX-5 conversion (also a huge topic; at least this one has an index). Though "only" 350 Nm of torque. Plus, it was not inexpensive, and took months to be manufactured and delivered.
and from options online even brand new the costs are quite reasonable, and availability is good.
As above, his motor was neither. [ Edit: But that doesn't mean you can't find one that is both reasonable cost and with good availability. ]
It's certainly doable, especially if you're on a tight budget. Though these days, second hand OEM drivetrains (e.g. Tesla, Leaf) should also be considered.Is anyone able to shed some light on if I’m heading down the right track,
