12FGT

12FGT is a Kollmorgen motor in the ServoDisc Pancake DC Motors series. It uses an integral tachometer to provide motor-speed feedback to the control system. The maximum motor-shaft inertia is 1,780 g·cm², indicating the maximum rotational inertia associated with the motor shaft. The motor wiring is 18 AWG, while the tachometer uses 22 AWG wiring for its feedback connections.

The motor has a basic length of 3.80 inches, a housing diameter of 6 inches, and a basic weight of 6.20 pounds. Its mounting interface has a 5.500-inch bolt-circle diameter and 0.500-inch-deep mounting holes with 1/4-20 UNC-2B threads. A 1.313-inch pilot diameter supports alignment during installation.

The output shaft is 0.625 inches in diameter and extends 1.375 inches from the motor. A 0.1875-inch-wide square key provides a mechanical connection for transmitting torque to the driven component. The motor supports an axial load of 150 lbf along the shaft axis. It also supports a radial load of 125 lbf when the load is applied 1 inch from the mounting surface.
