20PCS Vibration Motor DC3V 12000rpm Mini Vibration Motor Vibrating Motors for Projects Electronic Device Repair Single Board Computers Project Classroom Project Bristle Bots Cable 2in

My class was using these to make bristle bots and they worked just fine! The ends of the wires needed stripped a little more in order to connect to the batteries better, but for the price and such these fit the bill.

These 20 vibration motors are perfect for making mini cup robots and other DIY electronics. They run smoothly at 3V with a strong vibration at 12,000 rpm. The pack offers excellent value with plenty of motors for multiple projects or replacements. Ideal for hobbyists and educators looking for reliable parts on a budget.

Works like it should. Used for a stem bristle bot project with kids k-5th.

Great pack of button vibrations. Just attach to a button battery (not included) to make a Bristle bot for a student science experiment.

The motors themselves can take some abuse but the wires can come off if pulled too forcefully. Perfect for middle school bristle bot projects.

Perfect speed.for my purpose, making a wash mop on my robot vacuum/floor mopper vibrate, making it clean much better by causing it to scrub.

I used these to assemble kits for a Cub Scout activity making toothbrush robots. These were the perfect size to mount on the back of the toothbrush head and vibrates enough to move the robots around an obstacle course. The Scouts will be so excited to make and race these. These arrived within the timeframe given by the seller and were packaged well. If I need more, I'll definitely buy from this seller.

I did not like that it was smaller than expected. The expose wire was very short and it was hard to make contact with some of them.
