6 Pcs DC Coreless Vibration Motors 7x25mm Micro Vibrating Motors 1-6V 8000-20000RPM for Electronic Vibration equipments 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.

Better than expected!

I haven't Had these for more than a day, so I cant say how long they last. I plan to use these in small stuffed toy mouses for cats that will vibrate when the cat plays with them . Im unsure about some of the other reviewers that claim only a few worked. Thats why the first thing I did was test them all and they all worked great from 1 volt to 9 volts as they are designed to work at 3 but are given rating 1 volt to 6 volts but at 9 volts the one I placed aside for testing at 9 volts continuously worked for the 30 seconds until I turned off current and it was the fastest vibrating motor I've owned and the decibels didn't change, just the tone changing from low hum to a low high pitch sound if they burn out quickly at the 3 volt recommended by manufacturer that I will be using these at, I will Update this review.

I bought these for replacements for a massager and they perform great. Top of the line product at a decent price!

For customers who ask, "what do i do with them", um, consider the adult toy sector and you will have you answer.Let's just say that *waterproof* is your clue ;)Happy creating.

Strong for its size.

I added six of them to my Minni shaker table that holds 2 cups of dirt they right away started up strong and then start to loose there juice after about 10 mins they started dieing out .strange then I decided to remove one nope it was way to hot to grab i ended up removing and throwing them away in the trash once they all cooled down .

Nearly silent to 3v, with very little current draw and excellent vibration.Highly satisfied overall, will update with any interesting results found in further testing.
