I purchased this on CL for almost nothing, yet I'm not really sure what I bought. My hope was that I could use it to create a rotary table for a mill, or perhaps I could use the motor by itself to replace the single-phase turd on my drill press. Unfortunately, I don't know the motor specs (voltage or RPM), and I don't know why it has so many wires. I also don't know why the seller let it go for nothing when he made specific references to how much these cost on eBay. Here are my questions in a simpler format:
1. What type of machine was this likely used on? The owner said he had 3 of these in total, which made me think of XYZ motion.
2. How do I determine the motor RPM and Voltage?
3. Why does it have 3 wires? It spins when you simply hook the red and black wires to a benchtop psu at 12 volts, so I'm assuming it's a brushed DC motor. I don't know what the 3rd wire is then?
4. What's the deal with the 8 smaller wires? Are those simply for the rotary encoder?
5. Why are these so expensive? Do they have super-precision bearings inside? I imagine if those are shot, that would explain the low price on CL.
None of the numbers on the motor match anything on Google btw. I think it must've been a bespoke design for a specific piece of automation equipment.
