24V/82.6Kg-cm/33RPM 76:1 DC Gear Motor

The 3273 is a 24 volt gear motor, generating 82.6 Kg-cm of torque at 33 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 3273 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

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.
