These specifications are listed with the "rated" values (these are the values where the motor runs at peak efficiency). The motors can deliver considerably more than their rated values, refer to datasheet for more information.

We recommend controlling the motors with one of our motor speed controllers. See our motor controller support page for more information. We also recommend you use our wiring kit to wire your motors. The hookup kit will help suppress the electronic noise generated from any DC motor. See our motor wiring support page for more information.
These heavy duty gear motors have a rated speed of 285 RPM and a gear reduction of 1:12. They work great on our larger robots as well as many other applications.
These heavy duty gear motors have a rated speed of 136 RPM and a gear reduction of 1:26. These geared motors feature encoders and serve as excellent robot motors, but work great for other uses.
This robot uses custom length sides and 13 inch tires with IG52 136 RPM motors. We have included everything to make it ready to run including batteries, chargers, and a controller.
SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader.
