The Allen-Bradley 1326AB-C2E-11-K7 servo motor is a high-performance three-phase servo motor. It can be used with the Allen-Bradley 1391 AC servo controllers. Amplifiers can also be used with the servo motor. The 1326AB-C2E-11-K7 servo motor includes a 400 pounds on an inch rated holding brake with a 24 Volts DC coil. The frame diameter of the motor is 7.63 inches. The standard motor rated speed is 3000 RPM which improves to 4000 RPM with an Allen-Bradley 1391B-AA45 servo amplifier. The rated output power of the motor is 5.2 kilowatts.

* The Allen Bradley 1326AB-C2E-11-K7 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-C2E-11-K7 units instead of migration.
The Allen-Bradley 1326AB-C2E-11-K7 servo motor is a high-performance three-phase servo motor. It can be used with the Allen-Bradley 1391 AC servo controllers. Amplifiers can also be used with the servo motor. The 1326AB-C2E-11-K7 servo motor is part of the 1326AB series from Allen-Bradley which has standard rotor speeds ranging from 1600 RPM to 5000 RPM and a peak stall torque ranging from 840 pounds on an inch to 48 pounds on an inch. With amplification, the speed range extends from 2000 RPM to 6000 RPM and the peak stall torque range extends from 989 pounds on an inch to 48 pounds on an inch. Allen-Bradley provides the following options for this motor series: holding brakes, NEMA or IEC rated flange mounts, and a shaft seal kit.
The 1326AB-C2E-11-K7 servo motor includes a 400 pounds on an inch rated holding brake with a 24 Volts DC rated coil. The frame diameter of the motor is 7.63 inches. The standard motor rated speed is 3000 RPM which improves to 4000 RPM with a 1391B-AA45 servo amplifier. The rated output power of the motor is 5.2 kilowatts. The stator on the motor is a three-phase sinusoidal wound rotor which improves operation at low speeds. The motor winding has a torque constant of 7.44 pounds on an inch, an inductance of 1.5 Millihenry, and a terminal resistance rating of 0.088 ohms at 25 degrees Celsius. The performance specifications for the motor include a mechanical time constant of 5.3 milliseconds, 210 pounds on an inch of continuous stall torque (at 40 degrees Celsius), 420 pounds on an inch of peak stall torque, and continuous and peak stall current ratings of 33.2 and 66.4 Amps, respectively. The motor weight is 102 pounds and the rotor polar moment of inertia is 0.140 lb-in.s2.
