DCコアレスモーター内蔵振動防水1.5-3v 8000-16000RPM 電動歯ブラシ用モーター 7x25mm 5個

I got these for a Raspberry Pi project and use them as a vibration alert. You can see the variety of vibrations in my video where I cycle up from 0.5 VDC through to 3VDC, max current draw is approximately 0.09 amps. These appear to run cool even at max voltage.

I used 1v, 2v, 3v, 4v and 5v and they all worked just fine. These are strong and powerful for their size. I'm happy.

Tough little motors. A little smaller than I needed, but the description was 100% accurate. Overall, a good value!

Using it with a 3V remote controlled switch activation. Vibrator lays between two metal squirrel baffles, resting on the top of the bottom one. As the nasty birds fly in to ravage my seed intended for my song birds, a small momentary press and the device bangs on the baffle and scares the birds away. Rather therapeutic given the annoyance these birds are. Bluejays, Cardinals, Doves ignore the clanging, but not the black birds. Not sure if strain relief will be needed or if the device is durable in this unique application, but more than worth the price to find out and far more efficient than my remote RV car wheel with 3 AA batteries per week. Smaller than expected, but even better. Thank you.

These are small and powerful for their size. Just what I needed to build therapy stimulators. Runs great using 1 AA battery.
