The only motor in DW is part of the Time Expander. It's a 12 Volt DC motor which is connected to a gear box which moves the Expander up and down. The motor is not sold separately; it and the gear box are one piece. The motor+gearbox is manufactured by a company named Multi-Products in Racine, Wisconsin (262-554-3700). The Spec number is on the gearbox itself (#3228). Cost: $65. Older versions of the gearbox have a flaw in that they don't deal very well with the Time Expander getting stuck. If that happens then either the gears tend to strip or the gear on the central shaft disconnects itself from the shaft. In either case, the box is mostly useless after that. Later versions have reinforced the design to be more resiliant. As for the ym3012, what did you want to know? Oh, BTW, that webpage up above is Great! I'm gonna build me a moving head !-) -- Peter A.
