* The Allen Bradley 1326AS-B440G-21-K4 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AS-B440G-21-K4 units instead of migration.
The Allen-Bradley 1326AS-B440G-21-K4 Servo Motor runs on a 460V AC voltage and it has a frame diameter of 100 mm. It has a rated motor speed of 5250 RPM with an IEC metric flange with a keyway flange and shaft series. This servo motor has a motor rated torque of 6.4 Nm. It also has a motor rated output of 2.0 kW. The product has a system continuous torque of 6.4 Nm and a 10.5 Nm system peak stall torque. The 1326AS-B440G-21-K4 also features a 10.2 Nm holding brake w/24V DC coil standard option. This servo motor also features neodymium-iron-boron-permanent magnet motors which are useful in providing high peak torques, low inertias, and high accelerations.
The 1326AS-B440G-21-K4 servo motor which is compact, brushless, and environmentally rugged, has a variety of features including a UL listed insulation system, a TENV construction, an economical and compact design which can function even in harsh environments, a three-phase sinusoidally-wound stator field for smooth operation at a low speed, and neodymium-iron-boron motors which function to provide a high-torque-to-inertia rating. This allows for faster machinery acceleration. It also has quick-release IP65 rated connectors for easy maintenance and installation. This servo motor also has the ability to vertically mounted with the shaft positioned up or down and at any angle.
This servo motor has catalog numbers which indicate various components. A specific version of that component is identified by each character of the catalog number. The peak current of the 1326AS-B440G-21-K4 can be easily applied to the motor without causing any damage. It also features a mechanical time constant which is the time required for the motor to achieve its final speed of 63% when a voltage step has been applied. There is also the thermal time constant which is the time required for the motor windings to reach a continuous temperature rise of 63% with a constant watts loss.
