Allen Bradley 1326AB-C2E-11-A7

The 1326AB-C2E-11-A7 is a 3000 RPM rated AC servo motor. Is belongs to the 1326AB product line from Allen-Bradley which is designed for use in conjunction with servo controllers from the 1391 series. The 1326AB motor can be used with selected amplifiers, leading to increased motor speed and power output. The standard features available on the 1326AB motor include a permanent magnet rotor, a three-phase stator field for smooth low-speed operation, a brushless resolver based feedback, TENV construction, precision balance, and support for vertical mounting. Options available from Allen-Bradley for the 1326AB series include spring-set holding brakes with DC coils, a power supply for converting AC voltage to DC voltage for brakes, shaft oil seal kits, a junction box, and resolver feedback kits. Kits are supplied as accessories and need to be ordered separately.

The 1326AB-C2E-11-A7 servo motor has a 7.63 inches (194 millimeters) frame diameter. The standard peak operation speed of the motor is 3000 RPM which increases to 4000 RPM with a compatible amplifier. The 1326AB-C2E-11-A7 servo motor includes a 45.2 N-m holding brake with a 90 Volts DC coil. The standard power output of 5.2 kilowatts increases to 6.9 kilowatts with an amplifier. The standard continuous stall torque is 23 N-m. However, the peak stall torque of 47.5 N-m increases to 64.3 N-m with an amplifier. The current at the continuous torque for the 1326AB-C2E-11-A7 servo motor is 33.2 Amps. The electrical and mechanical time constant for the 1326AB-C2E-11-A7 servo motor is 13.1 minutes and 5.2 minutes, respectively. Allen-Bradley recommends that the motor be operated at ambient temperatures that do not exceed 40 degrees Celsius. At higher temperatures, motor performance degrades, leading to output derating. The motor weighs approximately 46.3 kilograms. The rated moment of inertia for the 1326AB-C2E-11-A7 servo motor is 0.015 kg-m2.
