A-B H-4050-P-H04AN Servo Component

Allen-Bradley H-4050-P-H04AN Servo Motor (H-Series Brushless Servo)

 

 

The Allen-Bradley H-4050-P-H04AN is a legacy H-Series low-inertia brushless AC servo motor used in high-performance motion control systems. It works together with Allen-Bradley servo drives (such as 1398 Ultra or legacy Kinetix/BRU systems) to provide precise position, speed, and torque control for industrial machines.

This is a servo motor (mechanical + electromagnetic actuator), not a drive or controller.
