The Allen Bradley 1326AS-B330H-21 Low Inertia Servo Motor is a cutting-edge brushless AC synchronous motor engineered for robust industrial performance. Featuring a neodymium-iron-boron rotor, this motor ensures low inertia and impressive acceleration, delivering high peak torque with a compact form factor. Specifically optimized for integration with the Allen Bradley 1394 motion control system, it operates at a three-phase 460 Volt AC input with an output power of 0.9 kW and a speed capacity of up to 6500 RPM. Its IP66-rated TENV enclosure withstands harsh environments, while a sinusoidal wound stator guarantees smooth performance even at low speeds. With a 2-pole brushless resolver for precise feedback, the motor offsets extra onboard electronics by generating up to 1024 ppr encoder output. Designed with a keyway and IEC metric flange mount, it operates efficiently within a temperature range of 0 to 40 degrees Celsius and supports versatile mounting configurations with dimensions of 246 x 89.5 x 93.0 mm, weighing 11.2 kg.
