12 Pack DC Motor 1.5-3V 15000RPM Mini Electric Hobby Motor for DIY Toys Science Projects

Estos motores fueron comprados para reemplazar los motores de unos juguetes. La verdad es que ahora los juguetes funciona mejor y es mucho mas barato reemplazar los motores que reemplazar un juguete caro. Definitivamente valio la pena esta compra.

A good entry for me anyway as I knew nothing about them. I've run 4 of the 12 and they all run. They are smooth and start up fast with bare shafts but start slowly and run rough with some 2-inch diameter 3D printed wheels with 1/4 inch thick O-ring tires (which are probably out of balance and out of round).For the price, I'm very happy but will use these for lighter duty in the future. There are much more expensive motors out there for Nerf guns, etc. and they would certainly be interesting.

All of the motors I have installed work great. I replaced motors in several Gearation boards. My son was thrilled to have his favorite toys functional again. The motors fit perfect, work great, and were easy to install..

They worked for the Art Bot Science Project that my daughter needed. One of them got hot but still performed okay

These are Cheap 13g 103 motors. 13g motors require a 1/3rd more power to operate, have far less torque, and don't last as long as 16g motors. I assume it is because they have 3g less magnetic mass and/or windings. Weigh your motors before completing your purchase.
