Allen Bradley 1326AS-B330H-21

The Allen Bradley 1326AS-B330H-21 Low Inertia Servo Motor is a brushless AC synchronous servo motor with a neodymium-iron-boron permanent magnet rotor, which provides low motor inertia, high peak torque, and high acceleration in one compact unit. This servo motor is designed for use with the Allen Bradley 1394 motion control system, and it features sinusoidal wound stator which provides smooth motor operation even at low speed, and TENV constructed IP66 rated enclosure for a harsh industrial environment. The 1326AS-B330H-21  has a 3-phase rated input voltage of 460 Volt AC, with a rated output power of 0.9 kW, and it has a continuous stall current of 2.1Amps, with peak stall current of 6.0 Amps. This servo motor has a rated rotor speed of 5370 RPM at 360 Volt input, and it has a maximum rotor speed of 6500 RPM at 460 Volt rated motor input. It has a rated motor torque of 2.0 N-m (18.0 pounds on an inch), with peak system torque of 5.6 N-m (50 pounds on an inch), and it has rated rotor inertia of 0.00009 Kg-m2 (0.0008 pounds per inch per second).

The 1326AS-B330H-21 has a 1.3 milliseconds mechanical time, constant at 40 degrees Celsius, with a 2.4-millisecond Electrical time constant and a 21-minute thermal time constant using Class B thermal insulation. This servo motor has 36 Volts per 1000 RPM winding voltage constant, with a 10.2-Ohm rated winding resistance and a 24.3 Millihenry rated winding inductance. The 1326AS-B330H-21 like all low inertia servo motors in the family has a 2 pole rugged brushless resolver, which provides accurate position feedback, and generates up to 1024 ppr (4096 counts/rev) A Quad B encoder output, thereby eliminating the need for extra onboard electronics. This servo has 75 millimeters stator diameter, with 30 millimeters magnet stack length, and it is designed with a keyway and IEC metric flange mount option. It has a functional temperature range of 0 to 40 degree Celsius (32 to 104 degree Fahrenheit), at non-condensing 5% to 95% relative humidity range, and it is stored at -30 to 70 degree Celsius (-22 to 158 degree Fahrenheit) range. The 1326AS-B330H-21 has a net weight of 11.2 Kilogram, and a mounting volume of 246 x 89.5 x 93.0 millimeters.
