I am trying to figure out the easiest options for building a cake stand that rotates no more than 3 or 4 rpm. I have found microwave turntable motors that have the reuired specs on rpm but they have 21-24 vac on the labels. I am assuming you would need a transformer? I want to be able just to plug it in since I am really weak on my electronics knowledge. Can I use a different type of motor and build/buy something that will reduce the speed to what I want. I am open to suggestions.
