A normal economy car can put out thousands of foot pounds of force, even anemic ones
This is why gearing does wonders for any system
Now if Ecky wants to reveal the type of ebike motor he uses I would love to put one on the back wheel of my Insight but I bet the bearings wouldn’t survive even in my 1800 lb car, I also bet the gas motor would need to launch the car.
That said, a hub motor would work fine at steady speed on flat ground but I bet it wouldcrud up and fail.
I would love to be proven wrong, cause I have wanted a workable hub motor for years, just none thus far work for a car  |
My car should weigh around 3000 lbs ish. I can't imagine that 200 ft lbs per hub motor, a combined 400 ft lbs, would be something to snub. At 4000 RPM my car produces 350 ft lbs torque, so think of the fuel required to get me there!
I don't know, the system offered by this University doesn't look cheap and under powered.
I suppose if worse comes to worse, I would have to figure out how to have this system programmed for those moments when my V8 starts to lose vacuum pressure under higher load conditions. This includes going from a stop, sudden acceleration, and even cruising on the highway and hitting a slight incline. I just thought it would make life easier to have the thing operating all the time and making sure that it was charging itself while it was in operation so that it wouldn't need to be manually recharged.
Certainly this is something that will require more time to research.
