Search for a super small super strong vibrating motor
(OP)
Hi all,
I'm trying to build something that will help me clean the inside of a long thin metal tube I use in my lab. What I really need is to apply multiple strong hits on the inner surface of the tube.
What I had in mind is inserting a vibrating motor (let's say – an electric motor with an eccentric mass) in order to apply the force. I don't have any problem with bringing a strong power source (voltage and current), and I can go up in price to a few hundreds and even thousands of USD if needed. My main constraint is to find something that will give strong hits (in the order of tens of Newtons and more if possible) against a rigid surface but without too much support on the other side (my plans are to inflate something inside to get the counter force). The tube diameter is 10mm (ID in aluminum tube) and I need to go through a turn that will limit me to about 6mm in length.
Any ideas for motors? I couldn't find anything I was sure is strong enough in an online search.
Any ideas for other ways to achieve the same goal?
Thank you very much in advance,
Gedanken

But first I'd notice that aluminum tube is cheap, and think about how many brand new clean tubes I could purchase for thousands of dollars plus my time designing and building a custom cleaner.

Obviously, if I were able to just throw away the aluminum and replace the piping, it would be much cheaper.
The idea is to clean a flowing system during an experiment, in which sediment is being created, and has to be removed with non-chemical means. I tried sonication, which did not work out well at all. The only thing that does work for me is scraping off the material, which is still not very effective. I tried removing it after an experiment with a vibrating part I took from a knitting machine, and it worked very well. What I had in mind was using the same effect with something much smaller, so I can actually insert it during an expriment (I don't mind it being there permanently, but I'd prefer to avoid it).
The idea of taking a motor from an electric toothbrush sounds very interesting, and I'm trying to get one. Also, I was unaware of the concept of "pigging", and it sounds exactly like what I am looking for. I will look into it.
Any specific suggestions for such a motor I can buy will be very helpful.
Thank you again,

Google search for "mini motors" - sponsored search had better results.
The whole "Make" (Make magazine), STEM, etc. movement is just full of cool, cheap parts.

Thanks again for the useful tips and suggestions. I bought several electrical toothbrushes, but the motors inside where rotating and not vibrating (causing linear up/sown motion of the head). Regardless, I am currently trying to use vibration motors by Q Motor from the 6A series. The motors are rated for 3V, which yields too weak vibration motion. I am currently applying 7V instead of 3V and get significantly more violent vibration (knowing I'll burn the motors in a much higher rate than they are designed for).
For now, it seems to be working OK. If there are any more suggestions - I'll be grateful for any idea or tip.
Thank you all again!

Fasten a mass on the shaft to the motor you have, off center, and it will vibrate like crazy.
