|

The Allen-Bradley/Rockwell Automation 1326AS-B660E-21-K6 servo motor is a brushless rare earth magnet servo motor. It uses rare earth magnets made of iron, boron, and neodymium to reduce its inertia and increase its acceleration and torque for efficient operation. The 1326AS-B660E-21-K6 brushless servo motor is part of the Allen-Bradley Bulletin 1326 series and it can be connected to axis modules from the Allen-Bradley Bulletin 1394 series in certain applications. It has a holding brake with a 24 Volts DC coil and a rated torque of 325 pounds on an inch. The 1326AS-B660E-21-K6 brushless servo motor operates at a rated voltage of 460 Volts AC.

Product Lifecycle Status*Discontinued/Obsolete

* The Allen Bradley 1326AS-B660E-21-K6 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AS-B660E-21-K6 units instead of migration.

The 1326AS-B660E-21-K6 Servo Motor is manufactured by Allen-Bradley and it belongs to the 1326AS Servo Motor Series. The Allen-Bradley 1326AS-B660E-21-K6 has a frame diameter, a voltage, and a rated motor speed. The product features a system continuous torque as well as a motor rated output. The Allen-Bradley 1326AS-B660E-21-K6 Servo Motor and the entire line of 1326 Allen-Bradley Servo Motors are designed and intended for high continuous output and they also provide optimal performance. In general, these servo motors come in three frame sizes and they have a broad torque ranging between 2.7 and 50 N-m. Each servo motor in the 1326AS series is compatible with the Allen-Bradley 1391 or 1389 AC Servo Controllers. They also feature the IP65 enclosure rating type.

These servo motors are perfect for Allen-Bradley Kinetix 2098-HVs, 6000, or 1394 motion control systems and applications. The 1326AS-B660E-21-K6 comes with resolver feedback or an absolute encoder as standard features, thus allowing the motor to endure and survive severe shocks as well as vibration. Additionally, the motors can tolerate and survive high operating temperatures. These motors are also fixed with a modern magnet design, comprising the magnetic flux orientation responsible for increasing the flux density. These features aid in improving demagnetization protection and also lower the harmonics and losses. All the 1326AS Series servo motors are compact in design and economical and so they can function in severe environments. They also come with a Neodymium-iron-boron magnet rotor for providing high torque-to-inertia ratings for a quicker light machinery acceleration. These products have three-phase sinusoidally wound stator fields to enhance smooth operation even at slower speeds.
