vibrating motor

I would imagine it's a small low voltage dc permanent magnet motor/gearbox with an eccentric weight or roller. Take the machine apart and have a look.

The vibrator in a play station hand controls is slightly bigger.

Actually it is a small DC motor with an off balance flywheel.

The vibrator in an sander is just a cam with a small offset.

I haven't opened a massage machine yet and I don't know if the circular motion is desired.

An ultra sound welder generates the vibrations using a crystal. Maybe that is what is required.

Somehow I doubt that cell phones use wee little motors . They probably use some type of piezo-electric gizmo that gets the shakes when zapped by battery volts.

I think it is a tiny motor and eccentric

Correct. I've played with them. No... not for that purpose.

What an eccentric idea. Quickly now, who can open up his/her cellphone first to check? As Engineers, it would not do to actually obtain a manual. Much more elegant to grab a screwdriver and pop the thing open. However, I'm still in favour of piezo's.

Have you seen the bristlebot that uses the motor from a mobile or pager to drive it along!

Tiny motor with eccentric... not induced piezo.

Probably the same kind of motor in bedroom toys...

Try RS Electronics they have a wide range of DC motors of different voltage ratings. Best of all they available in most countries... a quick internet search will get you on your way.

I have "Oysterizer" massager it has a solenoid coil and plunger which vibrates and gives massage.

"...or what kind of vibrating motor can i use which is stronger tha the one used in cell phones..."

Just how strong do you want it to be? Some Barcaloungers used to have built-in vibrators (don't know if they make 'em any more) and they can be researched at:

Beyond that, there are vibrators available (not readily nor cheap, but they exist) that can simulate earthquakes for room-sized building mock-ups. Maybe some detail on the application will get better results?

"there are vibrators available (not readily nor cheap, but they exist) that can simulate earthquakes for room-sized building mock-ups."

I have actually been in one of them. Down in Florida, there is a tourist attraction that has a lot of "illusions" on display. Most of which are interactive also.

Trying to remember what it's called, I believe it's The House of Wonders?

That would be one hell of a massage.

AC Current + coil, = 60 hrtz vibration. recripocating head electric shavers and clippers do not use motors and gears. Too many parts to break and wear out. KISS

What a welcome message. Even though I didn't contribute much on this thread, I'm sure everyone here appreciates the thanks and acknowledgment. If only more people would do this.

What type of project are you working on? We manufacture a wide variety of vibrators for all kinds of industrial applications... force ranging from 20 lbs up to 10,000...
