The 1326AB-B720F-S2K7L servo motor is an Allen-Bradley AC servo motor rated for 31.8 N-m of continuous stall torque at 40 degrees Celsius. The rated output of the motor is 11.7 kilowatts and the rated motor speed is 5000 RPM at 460 Volts AC. The 1326AB-B720F-S2K7L servo motor belongs to the 1326AB series of servo motors. The 1326AB-B720F-S2K7L servo motor has a 194-millimeter frame diameter and it comes with magnet stack length of 20 millimeters. The feedback option available on the 1326AB-B720F-S2K7L servo motor is a single turn high-resolution encoder. A holding brake rated for 140 pounds on an inch is included with the servo motor. The holding brake comes with a 24 Volts DC coil. The motor enclosure is rated as an IP 67 enclosure.

The 1326AB-B720F-S2K7L servo motor can be used with two 1394 series axis modules, namely the AM50 and AM75 modules. The peak stall toque with the AM50 module is 38 N-m and with the AM75 module, it is 56 N-m. The rated continuous stall current with both AM50 and AM75 module is 27.5 Amps. The peak stall current with the AM50 is 33.2 Amps and with the AM75, it is 50 Amps. The electrical time constant for the 1326AB-B720F-S2K7L servo motor is 9.5 milliseconds and the mechanical time constant is 6.6 milliseconds. The peak ambient temperature rating for the 1326AB-B720F-S2K7L servo motor is 40 degrees Celsius (104 degrees Fahrenheit). The thermal time constant is 60 minutes and the insulation class for the motor is Class H. For the motor winging, the torque constant at 25 degrees Celsius is 1.37 N-m and its inductance is 4.15 Millihenry. The approximate weight of the 1326AB-B720F-S2K7L servo motor is 138 pounds. The motor can be mounted vertically at any angle.
