Geared motor

This mighty little motor actually rotates at more than 1,000 RPM (rotations per minute), but the tiny gears attached to the motor shaft reduce the rotations to about 75 RPM. This ensures maximum torque to turn the wheels or gears of your projects.

The Geared Motor Cube is just one part of a circuit. Add a battery to power your creations, an LED to light them up, and a switch to take control!
