Ever seen a vibra-motor from a cell phone? It is just an usual dc motor with some weight on the shaft, but the weight is off axis to make it vibrate.Originally posted by micro@Apr 22 2006, 12:41 PM
I need a vibration motor but I cannot find it. May I know can I modify a DC motor or stepper motor to be a vibration motor? If it is possible, how do I modify it? Thanks.

Would this be applicable for a "back massager" as well?Originally posted by n9352527@Apr 22 2006, 07:07 AM
I usually use electrical screw terminal (cut one from a block), select the size that will fit the motor shaft. Get rid of the insulating plastic. Screw the motor shaft in one side and screw a load (piece of metal) in the other side. Make sure the load is unbalanced and the weight is appropriate.
Don't use stepper motor, cheap DC motor will do. You can scavenge one from broken tape player or whatever.

Sure... just make sure that you put the motor inside an appropriate case. You don't want the metal load to tear your "back", do you?Originally posted by dbwgwee@Apr 23 2006, 05:03 PM

Ah... If you'd mentioned the load would be 2-3kg then I wouldn't suggest the screw terminal block in the first place. It is just a block of terminal used to connect electrical wires in distribution (an example is here). It is quite small and only suitable for small motor and load. I had one with a 6V tape player motor and a small metal load connected.Originally posted by micro@Apr 24 2006, 02:15 AM
Thanks for your kind help. I have a look on pager and cell phone vibration motor. I think it is not enough vibration because I need it to vibrate a 2 - 3kg things. May I know what type of motor can I use or how do I modify DC motor to become vibration motor? Thanks.

If you need to vibrate up to 3kg load, you would need a proper chuck/mechanism to connect the load to the shaft to withstand the load _and_ you would need a motor with reinforced shaft bearing. As you can imagine vibrating 3kg load would exert quite substantial lateral force, depending on the speed.
May I ask why do you need the load to be so heavy?

I am quite amazed that the good old faithful vibrator hasn't been mentioned. Maybe the censors have been on the prowl.Originally posted by micro@Apr 22 2006, 09:41 PM

Not in so many words... I kind of perceived that the post about "back massager" has something to do with thatOriginally posted by windoze killa@Apr 25 2006, 08:58 AM

I guess that´s not 2-3kg, If you would make it that not all the coins are in the same time in the vibrating part.Originally posted by micro@Apr 25 2006, 05:49 AM
Sure, actually I plan to do a coin counter to vibrate the coin so that I may drop down one by one and count it. May I know how do I modify a DC motor and what size of DC motor can I use? Because I have visited many cell phone shops and toys shop to find the vibration motor and fail to find it. Thank you first for your kind help.
