I agree, I have been irritated with D&D and others by their desire to hide motor specs...
And actually motor power curves for EVs are almost as impossible to get as BSFC charts for gasoline engines, its some type of closely guarded secret you need big pockets to see. Never could understand it either though.
Miles is useless, they don't even know who made the motor or charger, I tried when I first got the miles to get the company names who made the components and Miles said they don't have any information.
As a result of their incompetitence I can't fix the onboard voltmeter (in the dash), I can't program the programmable chinese charger for silicate gel battery profile I have and I couldn't order brushes and springs for the motor and had to have them fabricated
Heck I can't even get a title. luckily I live in Wisconsin and can get plates under a provision in the law but now if I ever wanted to sell
Quite irritating I agree, only choice is to work around the problem, in any event.
Antidotally your big motor should be good to about 5000rpm, real world there are folks who have run much more but I have also seen my fair share of reports of my Miles goes 65mph and then a little later they need a motor.
The big motor should not have much issue with 96v, it will have LOTS of issues past 5000rpm, some will do more others won't. The big motor is very durable unlike my little 6.8" bugger which is strong but overheats.
Field reduction will get you to about 35mph and its easy, 96v will also but there is more cost involved and problems with the 72v dash working correctly.
The odd part is my small motor can actually spin faster meaning I can drive up to 46mph max but run the risk of overheating, because I have kept the powerfull
275amp controller I can throw 60v and field reduction for 45mph and the motor does not appear to overheat in the duration I drive, but it takes a mile or two to get up to full speed.
If you plan on making your miles go fast remember your range will suck and stuff won't be as reliable. I would strongly recommend a $200 transmission if you want to move faster or if you talk to the guy in Ohio you can buy an OR70 transmission which has the gears but no external way of shifting then you can go faster but can't shift.
