Product Lifecycle Status*Discontinued/Obsolete

* The Allen Bradley 1326AB-B430G-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-B430G-21-K4 units instead of migration.

The 1326AB-B430G-21-K4 is a ferrite servo motor that uses 460 to 380 Volts AC power belonging to the 1326AB series of motors. It is manufactured by Rockwell Automation/Allen-Bradley. It has a frame diameter of 108 millimeters with a bolt center of 115 millimeters and it weighs 16.8 kilograms. It has a holding brake that uses a 24 Volts DC coil. Replacements are available for the servo motors from the manufacturer.

The replacement is also in no way inferior to the original 1326AB-B430G-21-K4 because it is also subjected to the tests that the original must pass through and only then is it certified as a suitable replacement. The performance of the 1326AB-B430G-21-K4 servo motor is as good as any of its counterparts in the 1326AB series. It has a rated speed of 5000 RPM (460 Volts) and 4000 RPM (380 Volts). Its rated output is 2.3 kW with a rotor inertia of 0.001 kH-m2. It enjoys a system continuous stall current of 4.5 Amps. With a balance of 0.0127 millimeters, it has a 38 minutes thermal time constant which is notable compared to other servo motors in the series.
