The Allen-Bradley/Rockwell Automation 1326AB-B520F-21-TJB servo motor is a permanent magnet servo motor from the Bulletin 1326 product line. Its permanent ferrite magnets are installed inside it in a stack that is 2 inches long and these magnets both reduce the motor’s friction and increase its servo response. The 1326AB-B520F-21-TJB servo motor has a motor voltage rating of 460 Volts AC and a maximum rated motor speed of 3500 RPM. Its continuous stall current rating is 7.5 to 8.8 Amps and its peak stall current rating is 15 to 26.4 Amps. The 1326AB-B520F-21-TJB servo motor features a metric flange that has a keyway.

* The Allen Bradley 1326AB-B520F-21-TJB has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B520F-21-TJB units instead of migration.
The 1326AB-B520F-21-TJB is an Allen-Bradley servo motor that is engineered under the 1326 motor series. The 1326AB-B520F-21-TJB features 460 or 380 Volts AC power and it comes with a 149 millimeters frame diameter. The 1326AB-B520F-21-TJB has 3500 revolutions per minute capacity and it contains 13.1 N-m system continuous torque with 2.9 kilowatts motor rated output. The motor comes with a specially engineered housing unit that helps in reducing the motor length and it also increases the continuous torque ratings. The 1326AB-B520F-21-TJB features high performance because it is a three-phase brushless AC synchronous servo motor that is designed by Allen-Bradley. Each of the 1326 motor series motors features a special flux profile permanent magnet that is engineered by Allen-Bradley to increase the motors servo response.
The 1326 series servo motors also come with a three-phase sinusoidal wound stator field, offering the motors a smooth operation capacity even at low speeds. The motors also feature a TENV construction with an IP65 standard rating and an extruded aluminum housing for improved heat transfer. The motor comes with 100% continuous rated output torque at a stall. The 1326AB-B520F-21-TJB is UL-listed and it has the ability to be vertically mounted at any angle with shaft position flexibility. The 1326AB-B520F-21-TJB is available with a reservoir and high-resolution encoder feedback device. The resolver-based servo motor features rugged brushless resolver providing an accurate position feedback and eliminates the need for onboard electronics. The 1326AB-B520F-21-TJB has the ability to withstand harsh shock, high operating temperatures, and high vibration. The 1326AB-B520F-21-TJB also features single-turn configuration, providing a precise machine position of two million counts per revolution.
