  About 1326AB-B720E-21-L

•  

   

  The 1326AB-B720E-21-L servo motor is a Torque Plus brushless servo motor manufactured by Allen-Bradley. Its speed ratings are 3500 revolutions per minute at 460 Volts AC, 3000 revolutions per minute at 380 Volts AC, 30.9 N-m of torque, 88.1 N-m of peak torque, and 0.015 rotor inertia. Its power rating is 6.8 kilowatts, and the continuous system stall current rating is 17.5 Amps. Its IP 67 rated enclosure provides the protection needed to operate this motor in hazardous environments. The aluminum enclosure is dust-tight and it is able to withstand pulsating water jets without liquid entering the motor because its shaft features a seal kit.

   

   

  A threaded hole is provided on the face of the 1326AB-B720E-21-L servo motor’s shaft to allow it to be connected to couplings. Its frame diameter is 194 millimeters and the motor is engineered to reduce motor length without any reduction in speed or torque performance. The magnets in this motor are specially designed to increase servo response and the insulation material for its windings is designed to optimize heat transfer to ensure that the motor’s temperature does not exceed its recommended range. Note that the 1326AB-B720E-21-L Torque Plus servo motor loses its IP 67 protection rating when it is used with junction box kits, resolver feedback devices, or blower packages. As a component of the Allen-Bradley 1394 motion system, the 1326AB-B720E-21-L Torque Plus servo motor works with specific axial modules. The mounting flange option on this motor is an IEC metric mounting flange with a keyway that allows it to be mounted vertically at different angles regardless of whether the shaft is facing up or down.
