* The Allen Bradley 1326AB-B720E-21-K7L has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B720E-21-K7L units instead of migration.
The Allen-Bradley 1326AB-B720E-21-K7L is a Servo Motor that belongs to the 1326AB Torque Plus Series. It is a three-phase, brushless motor with a 194mm millimeter frame diameter and a 215 millimeter bolt center). The voltage rating for this synchronous servo motor is 460 Volts AC. It is particularly engineered to increase constant torque rating and reduce motor length. It helps satisfy the strict demands of high-level motion systems. This efficient servo motor also comes with an IEC Metric Flange with Keyway feature. The 1326AB 460 Volts Torque Plus AC Servo Motors (including the 1326AB-B720E-21-K7L) are UL Listed insulation motors. They reach speeds of up to 7250 RPM and have a relentless torque capability from 2.3 to 53 N-m. The high-performance servo motors under this series are meant to be used with the Allen-Bradley 1394 Motion Control System, Ultra3000 Digital Servo Drives, and Kinetix 6000 Servo Drives. For an improved heat transfer, each of the servo motors features an extruded aluminum housing.
This series also has multiple feedback options including Rugged, brushless resolver and Absolute multi-turn and single-turn encoder. They also feature a three-phase sinusoidal wound stator field and a special flux profile permanent magnets. These features are used for smooth operation and increased servo response. The motor speed rating for 1326AB-B720E-21-K7L is 3500 RPM while its motor output rating is 6.8 kW. It has a 30.9 N-m system of continuous torque and 88.1 N-m system peak stall torque rating. This servo motor also has a holding brake with 24V DC coil and IP67 environmental rating (standard option). The 1326AB-B720E-21-K7L, as well as the other torque plus servo motors, can be installed vertically or at an angle with the shaft elevated or lowered.
