Re: Serial PWM motor controller

Extremely useful information, thanks dtengineering.

To Daniel_LaFleur:

Car batteries usually have 40 Amp hours.
20% of that is 8 Amp hours.
Yes but what I said is that the battery cannot be drained lower then 20% charge. So if I'm right then that gives me 80% usable charge with is 32 Amp hours. Of course I'm the newbie here, maybe I'm wrong.

While I'm here, whats the difference between a stepper motor and a regular DC motor? I remember finding a small stepper motor in a hard drive and doing a bit of research on it but besides that their foreign to me.

Also, where would be a good place to look for cheap DC motors? I need something in between Vex motor size and FRC motor size. We'll call Vex small and FRC extra large, I want a medium.

Thanks,
