Ok so some of the PLCs.net vetrens may remember we/I started an electric go-cart project, but for various reasons it died on the vine. However, it's about to be re-born in a bigger and more elaborate fashon... I hope.
The plan is to construct a small two seater sporty looking car on a tubular alum frame powered by a 5hp 230v 3ph ac motor. Suspension, stearing, braking and the other chasis related components will be supplied by my good friend Kevin (who owns the junkyard two blocks down the street). I plan on spending a few (3 or 4)weekends this summer salvaging good looking used components from Horizons & Geos and the like.
To the meat of the issue:
The AC Drive: I've never applied DC to an AC drive, and am not quite sure how to select a drive for this type of application. I've figured that it's going to take 20-12volt batteries = 240vdc.
What's going to happen when I apply 240vdc to the drive?
What shuold be the low voltage cut-off?
How can I apply the regen from coasting & slowing or stopping?
RE-Charging? Should I recharge the batteries with 240v or 12v?
Budget for entire project ~$5K, much of will be eaten by the batteries, body & framework.
Open for discuession... Thanks, Mike.
