    Hello I have just purchased a synchronous motor for my Christmas tree - AC 12v 50/60Hz 1-2W
    I now want to purchase a mains power adapter to plug into the tree base.
    I have tried many Webb sites but no one understands what I am wanting.
    What exactly should I type into the search bar? Should the label on the adapter read the same as the motor, ( Output 12v ac 50/60Hz 1-2W) ?
    Hope someone can help.
    Many thanks
    John :)

    See if you can obtain a mains bell transformer here they come just above 12vac, the voltage is not critical.
    A straight transformer is not exactly a precise component anyway.

    Just one last question please, I have noticed that on my sync motor that both the wires are black.
    Not 1 red and 1 black? Which is + and - ?
    Thanks again.. John :)

    Gee, it's only June 1St and you're already planning for Christmas???

    I thought Christmas was getting too commercialized and the holiday season is getting moved up earlier and earlier. When Christmas does finally arrive, don't forget to start planning for the 4Th Of July. In some places, fire crackers go on sale in January. :D:p:)

    There is no + &- with AC, they 'Alternate';)
    The leads are bi-polar.

    Is it better to blow up government buildings in the summer?:confused:

    You might check with the Celts or Druids about Yule.;)

    DC is Direct Current - or current that is always moving in one direction - hence the need for a positive and a negative, and usually a red wire and black wire for positive and negative.

    AC is Alternating Current - or current that is constantly changing direction. There is no positive and negative in an AC motor or AC power supply. So you don't need a red and black wire; two black wires will do the job just fine.
