strange motor driver (early stepper?) what do you think? Answered

Hello everybody,
i got this motor out a damaged cine cam.playing about attaching power to the trailing wires from the board i get 2 speeds.

orange -0v
green +6v high speed
brown +6v low speed

motor makes a nice thrumming noise as it runs.looking forward to using it in something.
putting power direct to the motor wires is quite unresponsive.
going to try a pot between the 2 +ves that, work maybe getting variable speed.
(puting the +ves together got the same high speed as just the green wire)
anybody recognize this system? know how it works?

Boy, I've never seen one of those, and those circuit board components are strange too. I am going to guess that it is a shunt motor, I wish I could tell you more but I've never worked with them. . http://zone.ni.com/devzone/cda/ph/p/id/54
