Ok so I did figure out that this is a megatorque motor with analog resolvers on it.
It seems to be a 3 phase motor with A+, A-, B+, B-, C+, C connections. I'm thinking about attempting to build a controller for this thing. The problem is, I'm not sure how this operates compared to a standard 3 phase AC motor with U,V,B windings? The inside looks like a giant stepper motor but I'm fairly sure its a "servo" and not a stepper. Has anyone ever messed around with one of these?

Version control is standard for application code, but databases havent caught up. So what steps can you take to put your SQL databases under version control? Why should you start doing it?
