ID: 3274E_0

This DC motor has an encoder, a 168:1 gearbox, a rated speed of 15 RPM and rated torque of 173 Kg·cm.


Replaced by the 3274_1 and the 3531 - Optical Rotary Encoder HKT22, sold separately.

The 3274E 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.

This motor comes equipped with an E4P US Digital Encoder, which keeps track of the motor's rotation, allowing you to control your motor precisely.

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.

Comes packaged with


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.
