Hi all, as you can tell from the title, I am attempting to make a go kart from an old power chair (mobility scooter). There are two large DC motors but a lot of the electrical components are missing. We have the motors and that's it. No batteries, no nothing. So how do we make them spin? Here is what I have done so far. I am looking for verification on my spotty electrical knowledge.
First, I found the chair's replacement batteries on the internet. They have 12v and about 15A. The chair is called the Jazzy Select GT if you want to verify that information. The chair takes 2 batteries in series, and the motors are parallel. Since the actual batteries for the chair are too expensive, can we get away with using these batteries?
So that covers current (kinda) and voltage, but we need to steer the think by having variable speeds in each motor independently. So we need to control each motor's speed on its own, and I was thinking of doing this by having two variable resistors. If RI=V and V is 24, we would want 50 or so Ohms of variable resistance for each side. What resistors could you recommend?
Thanks in advance for all the wonderful help!
