The 1326AB-A3E-21-A4 Servo Motor is a high-performance AC servo motor manufactured by Allen-Bradley and belonging to the 1326AB Servo Motor series. It is fully compatible with the Allen-Bradley 1391 AC Servo Controller series. Its maximum operation speed and rated motor speed are both 3000 rpm. The rated continuous torque (at 40 degrees Celsius) is 5.4 Nm (48 pounds on an inch). The rated maximum stall torque is 10.84 N-m (96 pounds on an inch). The 1326AB-A3E-21-A4 Servo Motor has a 108-millimeter frame diameter and a stack length of 3 millimeters. It includes a 72 pounds on an inch (8.1 N-m) holding brake with a 90 Volts DC Coil. The motor has 16.8 kilograms (37 pounds) of weight. It can produce a rated output power of 1.2 kilowatts.

The 1326AB-A3E-21-A4 Servo Motor comes with a brushless resolver that provides feedback information on machine position, commutation, and velocity. It has a three-phase sinusoidal wound stator field to directly transfer heat for smooth and consistent operation at lower speeds. Ferrite magnets are used for cost-effective performance. It comes with a NEMA/IEC Metric Flange with a keyway. They can be vertically installed at any angle with the shaft up or down. This motor includes a 1326-MOD-BPS Brake Power Supply option that converts 115 Volts AC to the voltage needed for the 90 Volts DC brakes. The users can add an integral holding brake for keeping a load at a rest state if there is a need for an emergency stop. There are numerous applications and kits that can be applied to this servo motor, some of which are brake power supplies, shaft oil seal kits, blower cooling kits, and cables for power with extra length. For the 1326AB-A3E-21-A4 AC Servo Motor, an amplifier can be chosen individually based on the requirement of the specific motion control application.
