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.

Worked without issue and easy to solder wires. Great value as well.

These are great and they work

I was totally against this product because I couldn't get it to work the way I needed it to, but then I figured out how to use the field properties of the magnetism of the spin to modify the effect for lack of better terms. Since then it far as I know, it was pulled up to 20 volts and was still running fine I don't know the truth of that but that's what it is

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.

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.

bought for small projects. two of these were DOA. The rest worked great.

All units were clean and worked well, if a bit anemic. They draw about 11mA at 2.3VDC free on benchtop - up to 30mA when loaded down with my fingers.

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.

I was quite amazed at how low a voltage these little motors start turning at. In testing, I tried 2 different motors, and both would start at about 0.25V, and once running could be turned down to 0.2V and still keep going (albeit very slowly). This is very impressive! As for the other end of the spectrum, I think it is safe to say these are 3V motors, despite the ambiguity about 6V, since that is about where it reaches the specified max current of 70mA. I ran them up to 6V briefly, and they were at around 150mA. 100mA was between 4.2 and 4.7V (varies depending on how free it is to move about - more free, less current). Also, contrary to what some have reported, I did notice it getting warm when tested at and above the limit. Not hot, but certainly warmer than environment, so I wouldn't recommend going above the rated current for very long. I think the current draw is probably more of a hard limit than the voltage, since depending on how rigidly fixed the motor is, current draw will vary at a set voltage. I am now considering new applications for these given how low a voltage they work at - this is good news!

These little motors do vibrate pretty good, you can control the levels of vibration by controlling the voltage with a voltage regulator or similar product. I find that once the voltage gets above 6 the motors start to heat up, and at 8 to 10 they heat up really fast and very hot... don't go that high... I didn't test higher because I knew they'd burn out. They react kinda different at low vs high volts. They bounce around at some voltages but stay static and just vibrate at other voltages. So you can really modify and tweak what results you're going to get depending on what your plans are. The wires are VERY fine, so be careful with them. So if you're building your own wearable massager these should work great for you. Just have to get the right voltage control and secure the motors to ensure that's no stress on the wires.. I could see a lot of other uses too, like keeping powders flowing in a dispenser. Arts and crafts could use them to make things move... Anyways, they work well, and at lower voltages I think they'll have a really good life span.

I'm impressed with their performance. They are surprisingly powerful for their small size, generating strong vibrations that can be easily adjusted by varying the voltage. I found they started operating at very low voltages, which is a definite plus for my projects. The waterproof feature is also a standout; I tested one underwater, and it held up perfectly without any signs of water ingress. However, like another reviewer, I did notice that they heat up quickly when pushed beyond the 6V mark, so I’d recommend sticking to lower voltages to prevent any damage. The fine wires can be a bit delicate, so care is needed during installation. They can vibrate quite a bit, and the responsiveness varies with voltage, which is something to keep in mind depending on your application. Overall, these motors are a fantastic choice for hobby projects like VR feedback, model robotics, or even simple wearable devices. They’re compact, reliable, and offer great value for the price, making them a solid addition to my toolkit for future projects.

These little motors are quite responsive for their small size, I'm using these for a little VR haptic feedback project and depending on the voltage applied I am able to get a subtle movement or complete chaos. The size is perfect enough to be able to fit in a small cramped space, one of them I'm using in my mouse. One thing that I do not get is that in various parts of the listing it states 1.5 to 3v, and in others it says 1.5 to 6v, I'm not sure which one is true, however I did decide to risk sacrificing one of the motors to test, and after running it at 6v for 30 minutes it was only moderately warm, so it should be able to handle it. I also ran one of them under water for 30 minutes as well and although I am unable to confirm if any water penetrated the shell without tearing it apart, I can say that it still works great. Overall these are pretty capable little motors and I would be willing to recommend them
