1326AS-B330H-21-K3

The Allen-Bradley 1326AS-B330H-21-K3 Low Inertia Brushless Servo Motor is a resolver-based brushless AC servo motor used with the Allen-Bradley 1394 motion system which provides low inertia, high acceleration, and high peak torque in most applications. This servo motor features neodymium-iron-boron permanent magnet rotors which provide a high torque to inertia ratio, and it comes in a TENV class design with an IP65 standard industrial enclosure rating built for harsh industrial conditions. The 1326AS-B330H-21-K3 has an AC input voltage of 460 Volts AC, with a motor power rating of 0.9 KiloWatts, and with a system stall current of 2.1 Amps, which peaks at 6.0 Amps. This servo motor has rated rotor speed of 5370 RPM at 380 Volts AC and 6500 RPM maximum speed at 460 Volts AC, and it has rated motor inertia of 0.00009Kg-m2 (0.0008lb-in-S2). The 1326AS-B330H-21-K3 provides 2.1 N-m (18.0 pounds on an inch) of continuous stall torque with a peak torque value of 5.6 N-m (50.0 pounds on an inch), and it has a rated winding torque constant of 1.04 N-m (9.2 pounds on an inch) at 25 degrees Celsius.

It also has a 1.3 milliseconds mechanical time constant, with a 2.34 milliseconds electrical time constant, and it has a thermal constant of 21 minutes using Class B rated thermal insulation. This motor has a 2.5 Amps rated normally closed thermal switch which provides thermal overload indication, and it has a ruggedly built resolver which provides accurate position feedback and generates 1024 ppr (4096 counts/rev) A Quad B encoder output. It also has a 2.26 N-m (20 pounds on an inch) Holding Brake option with a 24 Volts DC coil which provides excellent braking, and it is designed with extruded aluminum housing for effective heat transfer. The 1326AS-B330H-21-K3 has a 75 millimeters frame diameter with 30 millimeters stack length, and it is designed with an IEC rated flange with a key, which provides the motor with the ability to be vertically mounted at any angle with the shaft facing up or down. It has an ambient temperature range of 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) at 5 to 95% non-condensing relative humidity range, and it has a storage range of -30 to 70 degrees Celsius (-22 to 158 degrees Fahrenheit). The 1326AS-B330H-21-K3 has an approximate weight of 4.3 kilograms with total shipping dimensions of 93 x 246 x 89 millimeters, and it is CE and UL certified.
