This revision of the 3274 is the same as the previous revision except that it has a metal plate on the back to make encoder mounting possible.

The 3274 is a 24 volt gear motor, generating 173 Kg-cm of torque at 15 RPM. It's a large motor that provides an amazing amount of torque.

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.

This revision of the 3274 has had its rear shaft and mounting holes changed to be compatible with the 3531 - Optical Rotary Encoder HKT22.

Connection

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

Warnings

warning The torque this motor produces when it stalls exceeds the rated strength of the gearbox. This means that stalling or very heavily loading this motor can cause serious damage to the gearbox. To avoid damage, avoid sudden loads or any load higher than the Maximum Strength of Gears spec.

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 can connect the 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. This motor requires higher voltage than our small motors, so only the following controllers are suitable:

Shaft Couplers

If you need to connect the main shaft of this motor to another device with a shaft, you can use a shaft coupler:

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 12mm bore pulleys and sprockets:

Rotary Bearings

Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the motor shaft. If you're using this motor to drive such a system, you can use rotary bearings to protect the motor:

Encoders

The rear shaft of this motor can be equipped with an encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor. The mounting holes on the back of this motor are compatible with the following encoders:
