Allen Bradley 1326AB-B720E-21-K7 Used Surplus

The Allen-Bradley 1326AB-B720E-21-K7 Torque Plus Servo Motor features a 460/380V AC voltage rating, with a 194 mm frame diameter, and a rated motor speed of 3500 RPM. This product also contains a 30.9 Nm system continuous torque as well as a 6.8 kW motor rated output. This Torque Plus motor has a specially designed housing which diminishes motor length and at the same time, it increases the continuous torque ratings. This results in creating high-performance, 3-phase, AC, brushless, synchronous servo motors which are products of Rockwell Automation/Allen-Bradley that are designed to meet the stringent needs of high-performance motion systems. The 460V series of AC servo motors are intended for use as part of the Allen-Bradley 1394 Motion Control System.

Each Allen-Bradley 1326AB-B720E-21-K7 Servo Motor features a special flux profile with permanent magnets specially designed by Rockwell Automation/Allen-Bradley to enhance the servo response. It also has a 3-phase, sinusoidal-wound stator field that improves low smooth operation speeds. These servo motors feature TENV construction, the IP65 is the standard enclosure, but the IP67 (-L) is also available as an enclosure option with an optional shaft seal (1326AB-MOD-SSV-xxx) installed. The Allen-Bradley 1326AB-B720E-21-K7 servo motor has an extruded aluminum housing for enhanced heat transfer. It has a 100% continuous-rated output torque when at a stall (0 RPM), a UL-Listed insulation system, and it can be mounted vertically at any angle with the shaft angled up or down. It usually has a closed thermal switch in its motor winding with a rating of 115V AC/ 24V DC at 1A offering a thermal overload indication.

The 1326AB servo motors come in either high-resolution or resolver (standard) encoder feedback devices. The resolver-based servo motors have a rugged brushless resolver which produces perfect position feedback, thus eliminating onboard electronics and allowing it to withstand harsh shocks and vibrations and high operating temperatures. The high-resolution 1326AB-B720E-21-K7 servo motor is accessible in either single or in multi-turn configurations which produce high-resolution encoder feedback for the applications that need precise tolerance.
