COPAL 30:1 Gearmotor

The built-on 30:1 gearhead provides a great amount of torque to the wheels while still being quite zippy. We recommend using our Foam Tires with this motor, as they provide good shock absorption for the small gearhead. Pre-wired with about 4" long leads.

Only 1.43" long, 5/8" diameter
weight: .88oz
52.49 oz-in torque @ 12V

770rpm @ 12V
390rpm @ 6V

Sanyo NA-Series Micro Geared Motors

This is truly the smallest gearmotor we've found, and it is top quality.

High quality all-metal gears with your choice of a very torquey 196.6:1 gear ratio, or a faster, but less torquey, 75.7:1 ratio. 

The entire motor with gears weighs only .3 ounces!  They are rated for 5.0V DC, but we have tested and run them at 9.0V, even up to 12V. Tires can be directly mounted to the 3 mm diameter output shaft. 

With these motors we will see a new evolution of tiny bots. YES, the prop adapter we sell will fit on these motors!
