Hello all as you can tell by my question I'm new to DIY EV's and this is my first post. I came across this Youtube video and it got me wondering:


If this gentleman can run a Leaf motor from a generic e-bike controller and throttle pedal can a hacked high power Tesla inverter from a model s or model 3 do the same thing?
Will the position signal (encoder signal) need to be modified?
What signal inputs do the Tesla inverters need?
What are the Tesla inverters outputs? I'm assuming it's a voltage sign wave ?

For me its cost and just a general question to gain an understanding. The bare leaf motors are ~$800 on ebay, plentiful and compact. They also seem to have more power potential than what they are limited to from the factory. Again if this is not possible then thats cool. I'm in the learning phase right now. But i have seen Arlin Sansome's 300hp CRX and wonder if that is possible with something "off the shelf" with a few tweaks.

Sure, it can be done, But why use a tesla inverter? Because of the name?
for most tesla motor conversions, the OEM internal inverter control board gets removed and replaced with an aftermarket one. Its easier to do that than to figure out and interface all the can signals and proprietary coding. The telsa inverter control board is 'kinda' separate to the IGBT driver board, so its a little easier for the aftermarket board to plug in place

Id suggest you'd probably be better using an aftermarket inverter to control the leaf motor (Cascadia Motion?), or, a better solution, Using one of the aftermarket solutions designed to interface and run the leaf motor. That'll get you up and running quicker than approaching it from scratch. Google lots, you have a lot of research still to do.
