The Allen-Bradley 1326AB-B720F-21 servo motor is a 5000 RPM rated AC servo motor. The frame diameter of the motor is 194 millimeters (215 millimeters bolt center). The magnet stack length is 20 millimeters. The motor comes with IEC metric flange with a keyway. The 1326AB-B720F-21 servo motor is part of the Allen-Bradley 1326AB 460 Volts AC Torque Plus series of servo motors. Torque plus servo motors have a special housing designed to reduce the motor length and increase the continuous torque rating of the motor. This family of 3-phase brushless motors is engineered to meet the strict requirements of high-performance systems. The 1326AB servo motors are designed for use with Allen-Bradley 1394 Motion Control systems.

The 1326AB-B720F-21 servo motor has a rated speed of 5000 RPM at 460 Volts AC and one of 4100 RPM at 380 Volts AC. The motor rated torque is 31.8 N-m. The rated power output of the motor is 11.7 kilowatts. The 1326AB-B720F-21 servo motor is compatible with the AM50 and AM75 1394 axis modules. The continuous torque and continuous stall current ratings are 31.8 N-m and 27.5 Amps, respectively. When used with the AM50 axis module, the peak stall torque and peak stall current are 38 N-m and 33.2 Amps. When used with the AM75 axis module the peak stall torque and peak stall current ratings are 56 N-m and 50 Amps, respectively. The mechanical time constant is 6.6 milliseconds and the electrical time constant is 9.5 milliseconds. The rotor inertia for the 1326AB-B720F-21 servo motor is 0.015 kg-m2. The weight of the motor is 62.6 kilograms. Thermal specifications include maximum ambient temperature rating of 40 degrees Celsius, insulation Class H, and thermal time constant of 60 minutes.
