Long time between posts
I have gotten to a point. Time to document some of the process.
Splitting the Big Junction Box into a High voltage and a Low voltage box was an EXCELLENT idea. It has cleaned up the issues with large diameter conductors crowded beside small gauge conductors, small terminal blocks always getting in the way, breaking off the backplate when the larger cables are not tethered well ... many issues, one solution.
I have been working on an AC drive for the sprint. It is as simple as I can think of right now. The power is not battery, but an extension cord. 120V from the cord through a 2000 va transformer to get 220V. This voltage fed into the drive. Drive sends 3 phase to the motor. Speed potentiometer gives a voltage reference 0 - 5 V for 0 - 60 Hz. Enable to the drive is a simple switch.
