12FGT by Kollmorgen

The Kollmorgen 12FGT is a robust addition to the ServoDisc Pancake DC Motors series, designed for demanding industrial environments. This compact gear motor delivers a continuous torque of 3.2 N-m while maintaining a low-profile form factor. Manufactured by Kollmorgen, the 12FGT combines a durable construction with high-performance output, ensuring reliability in heavy-duty applications. Key specifications include a gear ratio of 16.06:1 for enhanced torque multiplication and a rated speed of 189 RPM under load, making it ideal for precise motion control tasks. The module’s basic length of 3.80 in and basic weight of 6.20 lb enable flexible integration into constrained spaces without compromising structural integrity.

Technical capabilities of the 12FGT gear motor are centered around its precision-engineered drivetrain and electrical design. The peak torque of 7.7 N-m provides strong startup and overload capacity, while the maximum inertia of 0.0252 oz-in-sec2 ensures rapid response and reduced settling times. The motor operates at a nominal voltage of 19.4 volts and draws 7.4 amps under rated load, facilitating straightforward power supply design and thermal management. With a radial load capacity of 125 lb and an axial load rating of 150 lb, the shaft withstands significant side and end forces, supporting robust mechanical coupling in harsh conditions. The inclusion of a 16.06:1 gear ratio optimizes torque output, and the direct-drive tachometer interface guarantees stable speed feedback.

Operational features and benefits of the 12FGT highlight its advanced feedback systems and low-maintenance architecture. The integrated M23 optical encoder delivers high-resolution position information for closed-loop control, while the integral analog tachometer offers real-time speed monitoring and loop tuning. Brush design enhancements minimize wear, extending service intervals and reducing downtime in continuous-duty scenarios. Low rotor inertia contributes to rapid acceleration and deceleration, enabling precise motion sequences and smooth startup behavior. The gear motor’s balanced assembly ensures minimal vibration and noise, enhancing reliability in vibration-sensitive installations.

Integration of the 12FGT into industrial automation systems is straightforward thanks to its standard footprint and compatible mounting interfaces. The compact pancake design allows installation in tight mechanical assemblies, conveyor drives, robotic joints, and packaging machinery. Engineers benefit from Kollmorgen’s extensive support for electronic compatibility, including easy connection to controllers and drives. Whether deployed in factory automation, machine tools, or material handling equipment, the 12FGT gear motor delivers consistent performance and seamless integration across a wide range of industrial applications.
