6pcs DC Coreless Vibration Motor 7x25mm Micro Vibration Motor 1-6V 8000-20000RPM for Electronic Vibration Equipment and DIY Projects

I used these for haptic feedback on an electronics project. I had distributed them evenly around a belt and used some other devices to create a digital compass that always points to magnetic north. These are the second set of vibratory motors I purchased for this project. The first set were smaller disc motors that were not adequate for my needs. These worked super well and always provided feedback I could sense. I've heard that they can die out quickly if powered for too long. For small bursts of haptic feedback they seem to be a perfect fit and have not worn out. I also found that they all seem to provide consistent output. Sometimes motors outputs differ greatly when dealing with small motors like these.

I work a lot with molds. I use resin and plasters which need to be shaken down to get the bubbles out. I have tried all kinds of vibrators attached to the leveling tables I use, but each had their own issues, mostly the noise. I thought maybe these six mini vibrators might be enough to get things going, but I was wrong. All I needed to use was two of them. These little gems are a lot more powerful when it comes to vibration than they look. So don’t let the size fool you when you first see them. The construction is quality and yes they are very waterproof should you need to use them under water. With a variable power source you can easily adjust the amount of vibration you get with these. I find the best is around 4 volts. I use a very micro thin piece of silicone that is 2ml thick that I made to fit the vibrator to silence any noise as it hits the metal 2 foot square table I am using. Finally, with just two of these little guys I am getting perfect product from the molds. The frequency of the vibrations is very fast which won’t give a thumping sensation. The wiring coming out of it is very delicate so you need to be careful as you could snap them. I work with a lot of 22 gauge wire so I know they are delicate. But the way it is connected makes sure it won’t come off the connection to the motor. I would definitely recommend these vibrators mostly because they can be useful for so many things. I know these are going to last a long time and I don’t think I will need more. However, if I need a different type of larger one, etc., I am definitely going to be going to this company for them as this is pure quality.

My title seems negative but it is merely me stating that I lack the creative prowess to find a decent purpose for these. However, the motors work perfectly fine and are variable in power. Its speed adjusts depending on how much voltage runs through these motors. From the postings, the most realistic use case I have for these would be the bristle toothbrush or vibration motor robot.

These are great little motors that really vibrate fast enough to make some noise. Be careful attaching leads to the very very very thin black and white leads coming out the bottom. After that, it's a breeze.
