Allen-Bradley F-4050-Q-H00AA Industrial Servo Motor

Allen-Bradley F-4050-Q-H00AA is a brushless servo motor from the F-Series, designed for medium-inertia applications and built around a 4050 frame with a standard flange. This 8-pole, 4050-frame motor delivers up to 4,000 rpm and uses a 2,000-line optical encoder for closed-loop feedback, enabling precise position, velocity, and torque control when paired with a compatible Rockwell servo drive. The unit supports a standard option set and flange, and its motion characteristics include approximately 0.10 Nm/krpm damping and 0.11 Nm friction torque, which influence response and wear in continuous automation cycles. The F-4050-Q-H00AA's combination of frame size, encoder resolution, and medium-inertia design makes it suitable for automation tasks such as automated assembly lines, conveyors, packaging machines, and machine tools that require repeatable, programmable motion. It is referenced in 1398 ULTRA documentation as part of the broader Allen-Bradley servo motor family, reinforcing compatibility with Rockwell drives and the wider Allen-Bradley motion ecosystem for integrated control and cabling.
