They are DC motors that seem to be able to go fairly fast at 30V.
This is the assembly for the mill option on the converted lathe I had to throw away.
This is the bit I really wanted to look at as it would be the part to simulate.
After I got a few screws undone it came apart fairly easily.
Being able to easily use these motors and spindles means that I can shave a fair bit of the potential cost of this project and I can focus on more important things like how to get the rotational speed of the spindle when it uses a plastic belt and a DC motor to drive it. I'm thinking some kind of back EMF based system. However the lighting conditions probably won't change too much so some kind of light based system could also be used. This is particularly true of the lathe which has all of the mechanism inside the headstock and is fairly well sealed to light.
