This is completely random (as you know I tend to be), but has anyone considered a demolishion derby for vehicles like the Red Swift? Maybe it's the 4-years of living in the middle of nowhere and attending tractor pulls, but I yearn to experience a demo-derby. Big, rear-drive tanks are the norm, but what about a little maneuverable "firefly" with some un-drivable rust to buzz around the course and use the inertia to take out the opponents rad. Yeah, I have strange goals...
So you are building an electric car and know nothing about electric motors - god no wonder you are trying it - if you knew what I know you wouldn't even think of getting started. This is what keeps me from becoming successful. Anyway you need to measure the amps from the battery - a clamp on meter probably will not work unless it can measure DC current - most are only for 60 hertz AC measurements. If you have a shunt from the parts the rating on it indicates the voltage that develops across it when the amps are going through it. A 50amp 50mv shunt will generate 50 millivolts across it when 50 amps is flowing through it. If you have a DMM that has a 200mv scale like the $2.99 ones from Harbor Freight the lowest DC Voltage scale will show you up to 199.9 amps on the meter when connected to the shunt. Chances are the motor will draw about 5-20 amps but it will tell you how efficient the motor is and how much no load current it will draw. Which will tell you how much power you will loose driving around that doesn't get to the wheels.
Before eCycle would sell me a motor I had to prove that I knew what I was doing. Calculate torque gearing hill climbing ability etc. with fixed single speed gearing the design is much more critical. With the tranny gearing in your Geo(s) you should do ok.
had the flu this week, so didn't get much done on the forkenswift project (or any project).
but... as of today i've sold enough stuff from the red swift that we've made our money back on it. (and there's still a perfectly good motor - with decent compression even - that nobody seems to want.) i think it's reasonable to expect that by the time i'm done parting out the unnecessary stuff from both cars, they will be "free" or pretty close.
