Product Lifecycle Status*Discontinued/Obsolete

* The Allen Bradley 1326AB-B420E-21-K4 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B420E-21-K4 units instead of migration.

The Allen-Bradley 1326AB-B420E-21-K4 is a high-quality servo motor with 380 and 460 Volts AC voltage, providing maximum Amps and requiring proper handling and installation. This model has a 108-millimeter frame diameter, a 3000 rpm-rated motor speed which ensures constant power on even the most demanding tasks, a 5 N-m continuous torque for adequate streamlining, and a 1.1 kW-rated motor output. All these features give the motor an advantage over its competitors and enable it to perform excellently in the long term. In addition,

The Allen-Bradley 1326AB-B420E-21-K4 operates in 3 phases to ensure energy saving and continuous functionality regardless of any condition. As long as the servo motor is well-connected with the other components and hardware parts, the motor and the whole factory will operate at the maximum efficiency. It has a 2.84 Amps current rating along with a 250 Hertz quality line frequency. The actuator is a component of a system that involves relative adjustable positions between certain components. A servo motor is a component that acts directly or indirectly on components with adjustable relative positions. The actuator may be fixed, blocked on the system in its immediate vicinity, or contained in the subsystem of an adjustable positioning member. The power of the 1326AB-B420E-21-K4 servo motor determines the rate of change when it comes to the relative position and the frequency of that position. The power of the servo motor is inversely proportional to the precision of the actuator. The 1326AB-B420E-21-K4 servo motor provides simple, constructive solutions that require only low energy consumption, kinematics defined by linear, circular, or other combinations of motion. The technical solution defining the actuator has a wide range of applicability, being designed for a multitude of systems, inducing technical and constructive solutions for the systems where it is functionally approved, resulting in compact, modular, interchangeable, and standardized servo motor solutions.
