"nr 15 most likely a stepper motor but could be a synchronous dc motor"
That's a new one on me. What could a "dc synchronous motor" possibly be in-synch with?
#15 has a name plate and lists a speed (can't be a stepper) and lists inductance (probably isn't DC). Two sets of wires could be windings/starting cap; windings/tachometer; run winding/start winding; dual-voltage windings.
#2 has three wire colors, black, white, green. From that, I'd assume it's an AC motor.
What is the point of all this, anyway?
