Long story short, I want to convert one to use a new control board but without sacrificing the step motors. So I have now carefully removed one step motor (Z-axiz) and opened it up to see what's inside it.
Based on what I have gathered from searching around and posting a question on stack exchangel, this motor is most likely a bipolar motor with 10 windings.
|Removed connector housing.
|10 wires + ground.
|Motor removed from belt
|Belt drive with tacho generator
|Heat-sink with thermal paste.
