Product Details:

Allen-Bradley 1326AS-B440G-21-K4/A belongs to Rockwell Automation 1326AS low inertia brushless AC servo motor series. Rated 2.3kW, 380-460V three-phase AC input, rated speed 4500RPM. 21 stands for resolver feedback, K4 is custom shaft and connector option, /A represents Series A hardware revision. This is a discontinued compact low-inertia servo motor, designed to match Allen-Bradley 1394 servo drive system for closed-loop industrial motion control.

This servo motor adopts neodymium-iron-boron permanent magnet rotor, featuring low rotor inertia, high acceleration performance and high peak torque output, suitable for fast start-stop and high dynamic positioning applications. Built-in rugged 2-pole resolver for position and speed feedback, resistant to high vibration and wide temperature range. It adopts TENV totally enclosed non-vented construction with IP65 protection grade, aluminum extruded housing for better heat dissipation. Integrated thermal switch inside winding to trigger over-temperature alarm. It uses metric flange mounting with keyway shaft. It complies with UL industrial standards and is widely used for spare part replacement and maintenance of legacy automation equipment such as packaging machinery, material handling and CNC auxiliary axes.

Each Allen-Bradley 1326AS-B440G-21-K4/A undergoes strict factory testing before shipment, including running test, insulation resistance test and resolver signal verification to ensure reliable performance in industrial environments.
