Hi!So, I'm currently going through the design process for a high performance '82 Corvette electric car conversion. I'm looking at using AMR-250 90 single motors from EVWest, and after building a rather nifty calculator for spec analysis, I've figured out that the best way for me to meet my performance goals is to use 4 of them, one to power each wheel. I've looked at in wheel hub, and because of the associated performance issues with unsprung mass and the size of the motors, it's not practical. Because of this, I'm now looking at putting the motors in the axle assemblies: each motor will have a planetary gear reduction on the output, and that will be connected to a halfshaft connecting it to the wheels. It's essentially 2 motors pretending to be a very large differential. My problems are twofold:
First, what is the best way to convert an '82 corvette from having a nondriven front axle to having a driven front axle? I don't need most of the features associated with AWD. The way I see it, I just need an FWD axle that can go in an '82 Corvette, but what would that be? Tell me if I would be better off posting this in another forum, by the way.
Second, would my plan with the motors work?
That certainly sounds interesting. Can you quantify the performance goals you want? As I think about this, I would be more concerned about the batteries. Specifically, when the throttle is applied assuming 4 controllers, that's a lot of current. To get a battery pack to supply that much current is a very high discharge rate, meaning not a lot of range. What type of range are you looking to achieve? Simiilar to ICE engines, the whole system has to work together, fuel supply, cams, compression ratios, suspension, tires... Some depends on how much of the car you are willing to
alter. Where can you put all those batteries. Look forward to hearing more about this project.
