It's an AC motor so it needs Paul's Magic Motivator between the batteries and the motor.
The coupler is the part that always had me nervous. Electrical stuff is a bit easier. Especially to modify, enhance, relocate etc. The mechanical stuff needs to be spot on and you won't know you have got it wrong until you are nearly finished. A bit of misalignment may not be obvious to look at. It might not even show up in stationary tests but then when you get on the highway and the engine bay sounds like it is holding a jackhammer captive then it is a big problem.
So we went a bit overboard on the coupler to get everything aligned, balanced and strong. I think it is probably a bit (lot) over engineered.
If you don't have the engineering background to correctly model something then just work out what seems reasonable and then double it.
