12V Black Lego motor (bb22)

[Burf2000]

Does anyone know any technical info on this. I have one and plan to use it to drive a compress or 12v track however I looked up Philohome.com Motor Comparison and sadly he only did 9v.

I trying to work out if its better to run a 9v motor at 12v or use the 12v which I would prefer.

The black 12V motor is externally identical to the old gray 4.5V motor. Both are ungeared, direct drive motors with about the same power. They just have different voltage requirements and therefore use different battery boxes. I think the 12V was really intended to be used with the old train regulators because the set didn't even come with a battery box. Neither of these motors is very well suited to modern use, although they can be integrated into a model with enough gearing down. It takes a LOT. The best way to do this is with the old gearboxes from set 872 which give you 100:1.
