Description
Pittman GM8712-31 GM 8000 LO-COG Brush DC Gearmotor 19.1VDC 60.5:1 Ratio
The Pittman GM8712-31 is a compact brush-commutated DC gearmotor from Ametek's Pittman GM 8000 Series, featuring the brand's proprietary LO-COG design that minimizes cogging torque for smooth, low-noise rotation at low speeds. At 19.1 VDC with a 60.5:1 integral gear reduction, it delivers up to 0.325 Nm of continuous torque at a maximum output speed of 720 RPM. The motor terminates in a 2-pin connector with blue and orange lead wires.

Applications
Pittman LO-COG gearmotors from the GM 8000 Series are widely used in precision motion control applications where smooth, low-cogging rotation is critical. The "J13 Print Ribbon" tag attached to this unit's lead wires indicates it was originally used in a printer or document-handling mechanism — a common application for this motor series, which appeared in a range of office automation, medical, and industrial equipment from the 2000s onward. General applications include document feeders, label and ticket printers, lab instruments, robotic joints, camera and optical positioning stages, and other low-speed, moderate-torque automation tasks. The 60.5:1 gear reduction makes this motor well suited for applications requiring controlled, precise shaft movement rather than high speed.
This Pittman GM8712-31 GM 8000 Series LO-COG brush-commutated DC gearmotor is in used condition, pulled from a working environment where it was previously in service. It has not been powered or tested at our facility. The motor body shows typical used-equipment wear including some surface discoloration and handling marks; handwritten markings are visible on the housing. The lead wires and 2-pin connector appear intact. A paper label tag ("J13 Print Ribbon") is attached to the lead wires, indicating its prior application. Please review our photos for a full view of the cosmetic condition and contact us if you have any questions.
