1326AB-B730E-M2K7L

The 1326AB-B730E-M2K7L servo motor is an Allen-Bradley 1326AB series brushless AC servo motor with a magnet stack length of 30 millimeters and frame diameters of 194 millimeters. The motor supports 3-phase input at 460 Volts AC or 380 Volts AC. At 77 degrees Fahrenheit, the rated motor speeds are 3350 and 2800 RPM at 460 and 380 Volts AC input voltage, respectively. Integrated features available on the motor include a multi-turn high-resolution encoder and a 140 pounds on an inch rated holding brake. The integrated brake has a 24 Volts DC coil. The environmental rating of the motor enclosure is IP 67 and the motor comes with shaft oil seal kit preinstalled. The maximum ambient temperature, which is the temperature at which the motor can be operated at rated loads without exceeding the insulation temperature limits, is 104 degrees Fahrenheit. The thermal time constant, which is the time required for the motor windings to reach 63% of the continuous temperature rise with a stable power loss, is 60 minutes.

The motor rotor polar moment of inertia for the 1326AB-B730E-M2K7L servo motor is 0.22 lb-in-s2. The motor weighs 138 pounds. The torque constant is 2.01 N-m (at 77 degrees Fahrenheit). The voltage constant is 126.2 RMS (at 77 degrees Fahrenheit). The power output for the motor is 9.6 kilowatts. When used with the AM50 axis module, the peak and continuous stall current ratings are 33.2 Amps and 22.8 Amps, respectively, while the peak and constant stall torque are 502 pounds on an inch and 345 pounds on an inch, respectively. When used with the AM75 axis module, peak and continuous stall current ratings are 85.4 Amps and 22.8 Amps, respectively, while the peak and constant stall torque ratings are 756 pounds on an inch and 345 pounds on an inch, respectively.
