The 3261 is a 12 volt gear motor, generating 0.24 Kg-cm of torque at 1080 RPM. It's a small, inexpensive motor suitable for low torque, high speed applications. This motor is quite compact considering the amout of power it can output.

The planetary gearbox on this motor is more sophisticated than a typical spur gearbox and will provide greater efficiency, higher torque, and quieter motor operation.

Connection

This motor can be controlled by a DC motor controller. You can find a list of suitable controllers on the Connection & Compatibility tab.

DC Motor Controllers

DC motors can be simply connected to a power supply according to their rated voltage in order to make them run, but if you want to have control over direction, velocity, and acceleration in real-time, you'll need to use a motor controller. In order to connect this motor to a controller, you'll need to solder wires to the contacts on the back of the motor and connect those wires to the motor terminal on the controller. Don't worry about wiring the motor backwards; doing so will only reverse the direction of rotation.

Pulleys and Sprockets

If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Primer. Here is a list of our 6mm bore pulleys and sprockets:
