The Allen-Bradley 1326AB-C2C-21 High-Performance AC Servo Motor is a high-performance brushless servo motor in the Allen-Bradley 1326AB family of high-performance 3-phase brushless synchronous motors, designed to meet the tough and precise requirements of servo system applications. The 1326AB-C2C-21 features a permanent magnetic rotor, 3-phase Sine-coded wound stator filed 100% output torque at zero RPM, and a standard rotation speed of 2000 RPM. It has a rated 460V AC operating voltage, with an output power of 3.5kW, and a continuous stall torque of 23.7N-m (210lb-in) at 23.3A and a peak stall torque of 47.5N-m (420lb-in) at 46.6A. The 1326AB-C2C-21 has a rated standard motor speed of 2,000 RPM at 460V AC when used with the 1391B servo system, and it can attain a speed of up to 3,000 RPM when used with the Allen-Bradley 1391B-ES/DE servo system. It has an operational mechanical time constant of 5.4ms (time for the motor to reach 60% of its final velocity), with an electrical time constant of 13.1ms, and it has a thermal time constant of 71 minutes.

The 1326AB-C2C-21 offers a load-to-motor ratio (Inertia) of 0.016Kg-m2 (0.140lb-in-S2), with an e.m.f constant (KE constant) of 72.4V/RPM, and it offers a Sine Wave Torque constant of 1.20N-m/A (10.60lb-in/A). The 1326AB-C2C-21 has a rated phase-to-phase winding inductance of 0.18mH, and it has a rated 194mm frame diameter, with double stacking. It offers a high precision balance of up to 0.0127mm peak-to-peak displacement, with 100% rated torque output at a stall, and it is designed with an integral resolver feedback device which provides accurate position, commutation, and velocity feedback, and it generates 2048ppr A Quad B encoder output. The 1326AB-C2C-21 has a NEMA/IEC Metric Flange mounting option with a keyhole shaft, and it comes in IP65 rated dust-tight enclosure, designed to withstand harsh environmental condition, and to prevent liquid from entering the motor. The 1326AB-C2C-21 has a functioning temperature range of 30 to 70°C (-25 to 158°F) at 5 to 95% non-condensing relative humidity, and it is designed to withstand a 10G shock for 6ms and a 2.5G vibration at 3 to 2000Hz. It weighs about 46.3Kg (102lb), and it has total shipping dimensions of 193.8mm x 468.4mm x 173.7mm (7.62in x 18.44in x 6.84in) with a keyhole dimension of 10mm x 8mm x 50mm (0.31in x 0.31in x 2.00in).
