Inexpensive motorized turntable up to 10 lb load

  1. Mar 22, 2010 #1
    I'm trying to design and fabricate a dc motorized turntable (24" diameter fairly light-weight pressed wood table top) to rotate at various slow speeds between 1 revolution per hour to perhaps as fast as one revolution per minute carrying a load of up to 10 pounds on a lazy susan type ball bearing fixture to serve as a stand for a revolving centerpiece.

    I've found hobby type motors (with planetary gear box, etc) that seem like they may work, but I believe they may be noisy and they range in power to 3v to 5v and I am wondering how long a 3 volt battery would last on a 3v motor (I realize it must depend on the load) but it would still be good to have a ball park idea.

    I would rather avoid the costly and time consuming trial and error method of buying and trying different motors and batteries but frankly I'm completely out of my depth here (yes, I realize it's like wading-pool depth to engineers). So, I was wondering if you would be so kind as to point me in the right direction for the simplest and least expensive solution to the problem at hand.
    Thank you very much,
