Hi all,
I had this possibly stupid idea to figure out how to make an electric car. This isn't to say I will make one, but hey, everyone needs that one neat idea, right? Just for fun, I was thinking a 400-hp sports car.
I know that one could get a 100-hp motor for like $4000 or so, and I figure if you have 4 of them you then have a 400-hp car (because simple math is always right, right?). Only problem I see with this is that most motors tend to be rated at a certain RPM, and cars tend to need variable RPM. How would one go about doing that? Could just a high-power potentiometer used as an attenuator on the power input on a pedal act as an accelerator? Then of course turns would be an issue given that wheels have to rotate at different rates. That could be made easier by using only 2 powered wheels, I suppose.
If you can't tell, I've never used an electric motor, so I have nearly no idea how they work. And yes, I do know that electric motors and required battery and possible other electronics (like a reverse switch or whatever) can weigh too much to make a viable car, but it's just an idea at the moment. I mean the braking system so far is just to let off the accelerator!
But seriously, if you know how motors work, know what kind would work best, and how to vary their speed, that would be useful, even for smaller motor projects. I build synthesizers, audio gear, and voltage processors; I have no experience doing this kind of work! Thanks in advance.
