Electric Motor for Rotating Cylinder

Seem to me electric gear motor are too noise

Well use something else, then.

You might also search on line for 20-rpm shaded-pole gearmotors.

I would go with a microwave oven rotational base motor....

good idea, I wonder about continuous duty?

"As you can see in the picture the cylinder (4'' diameter x 8'' long) is connect to a electric motor"

What picture?

This may or may not be the picture....

Why not have the wheel with a hub motor and eliminate the cylinder and drive all together?

how much weight are we talking about??

on top of the cylinder will be a car tire, I guess about 7/8 pounds

A typical tire weighs 17-25 pounds. Add the weight of a wheel and you're at 40 pounds.

Typical artist. Don't know what you want, just what you don't want.

This↓ should be quite enough for you:

Your answer is to insult the poster if you can't provide them an answer because the poster isn't providing all the information ( in your opinion maybe) necessary for your response. If you don't have an answer to the subject, ignore the post. Your unprofessional, rude and obnoxious comments are meaningless and offensive.

Just adjust the heat applied to get the desired rotational speed.

Can't get much quieter unless you use a noisy candle.

I see no picture. May be I am blind or it is a transparent one.

There are means and ways to make it insonor even if it is an electric gear motor.

You can also use a weight motor as in old clocks, some run for a week!

What happened to your vertical lift motor project of 2010 ?

Thank you to ask me, I used a gear electric motor and it worked well but it's too noise. Here the project I have in mind

I'm curious as to what your going to do with your design? It sure looks like the mounting and spin up motor for the WWII Bouncing Bombs

Great link ! I remember them, nice to see the details. There was a movie made about them wasn't there? Dam Busters I think it was called. For this application OP is talking about only 3 rpm I think, as opposed to the inventor's specified 500 rpm. Any useable implementation of the original design IMHO would be "difficult" and not something that would be aided by suggestions on this site.

A record turntable motor could work. They are silent, and some are belt drive.

Check out drum motors. These are motors built into a conveyor roller. Various manufacturers but try Interroll or Vandegraff,

Thank you to all for the suggestions, I did some modifications from my first idea and I show how the project it will be, all the turntable and microwave motor are fine but it will be not powerfull enought as you will see in my mew image to make turn a car tire that weight about 20 pound. Seem to me a windscreen wiper motor it is a compromise for price and noise. Do you know any web side were I can find belt, pulley, flange to enclose the motor, cylinder, belt?(the electric motor, belt will be not visible but inside a box, the tire will be visible)

Thank you

You might take a look at this, U.S. Patent 3633295, Rotating tire display. Some one may have beat you to it?
