BOJACK 7x25mm DC Coreless Motor Built-in Vibration Waterproof 1.5-3v 8000-16000RPM Motor for Electric Toothbrush (Pack of 5)

I bought these to make vibration wands for degassing silicone and pu when mold making and casting. an Old "ultrasonic" toothbrush seemed to work ok, so i figured i'd try something a little stronger at a similar vibrational frequency as I don't have the money or room for a vacuum chamber right now.

I had a student making toothbrush robots and these worked great. It was easy to use and made the robots move.

works well when hooked up to a simple 1.5v AA battery, pretty powerful.

These vibration motors are excellent for a product we are developing. All 5 motors worked perfectly. They draw 94mA @ 3VDC. They all worked well after being submitted to our drop tests (critical for the product we are developing. We did not test the waterproof feature ass it does not apply to our product. These provided strong vibration @ 3VDC. A little super glue easily and securely attaches them to the metal enclosure. We are planning to purchase in production quantities for our product. If you need a source of vibration, consider these little motors.
