Question about motors and voltages
Hello,
I am working on a project that will require creating a motorized lazy susan. I found videos showing how to do this using a microwave oven motor, but all of the microwave oven motors I have found are either 220v or AC21v. Can either of these motors be used with 120v? Most of the motors I've seen are 4 watts.
Thank you.

Here are120V motors.
Search for syncronous motor, you will find various speed and voltages.

Welcome to the forums.
The motors for microwave oven turntables are not very strong.
Will they be strong enough to do your job ?

Hi Pete,
The videos I saw were demonstrated with considerably more weight than I plan to use. I want to put a plant on it and have it rotate slowly so that the sunlight is more distributed. I find it interesting how plants bend and move to get the best sunlight, and am curious how a plant will react to this type of rotation.
Thank you.

In a microwave oven application..... the platform that turns is sitting on a "ball bearing" type raceway so that it is balanced and spins easy. If you can maintain that it should be fine.

Hi Lambition,
Thank you for the examples. The best option I found was for a cup holder that ran at 1rpm, but since the videos I saw all used microwave motors I wasn't sure if the cup holders were strong enough for my needs. I want to put a plant on it and have it rotate slowly. The microwave motor in your first link runs at 5rpm. Is there a way to add a speed control?
Correction: It was a turntable motor. Here's a link: Turntable motor
Thank you.

Seems like you're re-inventing the 1,500 AD Tudor English gravity powered "spit jack" or "bottle jack" which was developed to evenly cook meat in front of a fire by using gravity to drive a rotisserie motion over several hours. A bottle jack works on gravity and clockwork cogs.
A simple lego-gear-reduction-chain, fan blades, and a spindle should allow you to construct a slowly turned-by-gravity gadget that rotates the plant as it drops down a rope.
If you get a looped rope/cord, then you should be able to do the spinning plant just based on clockwork and gravity.

There really isn't a easy way to control synchronous motors. You can control speed by changing frequency, but I doubt small motors like that will have enough torque at lower speed.
Turntable synchronous motors speeds are set at the factory using gears instead.

The best thing to is to get a timer that supplies power to the motor for xx seconds several times a day or once a day. There are hundreds of timers on ebay. The one in the link allows 16 settings per day but the interval is at least 1 minute. Look for one that runs on 120v and has multiple settings per day with a 1 second minimum.

FYI I have a planter full of herbs on a deep windowsill, to keep the herbs from growing in one direction, I set the planter on the rotating glass plate and 3 wheeled bearing salvaged from an old microwave oven.
The microwave turntable is easy to spin, just turn it an eighth turn each day when you water it.
