24V/5.1Kg-cm/588RPM 4.25:1 DC Gear Motor

ID: 3269_2

This DC motor has a 4.25:1 gearbox, a rated speed of 588 RPM and rated torque of 5.1 Kg·cm.

Replaced by 3269_3
Replaced by the 3269_3.

The 3269 is a 24 volt gear motor, generating 5.1 Kg-cm of torque at 588 RPM. It's a large motor that provides lots of torque, even at higher speeds.

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 3269 has had its rear shaft and mounting holes changed to be compatible with the 3531 - Optical Rotary Encoder HKT22.

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:

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:

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.
