How do I power an 21V AC motor?

I have a motor used for the rotating table in a microwave. I'd like to use it to slowly pan my camera at an even speed. The only problem is that now it's out of the microwave


The microwave must have a transformer to produce the proper voltage. Without that, you could use a 24 volt control transformer that is commonly used in home hydronic heating systems. These are available from any plumbing-heating supplier and will generally output about 25 to 26 volts which is a little high but should be O.K. Connect the transformer primary up to a conventional power cord and plug it in to a wall outlet. If you wish to reduce the voltage, you may be able to get good results by connecting the power to the transformer through a light dimmer, with a volt meter to measure the voltage to the motor.
