* The Allen Bradley 1326AB-B430G-21ML has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B430G-21ML units instead of migration.

The Allen-Bradley 1326AB-B430G-21ML is a servo motor that runs on 460/380V AC voltage. It has a 5000 RPM rated motor speed and it measures 108mm in its frame diameter. This device contains a 6.4 Nm system continuous torque and a 2.3 kW motor-rated output. The 1326AB-B430G-21ML is part of the torque plus motors series and it has a special engineering enclosure. This enclosure is meant to increase the continuous torque ratings and to protect the servo motor. These high performing 3-phase brushless, AC, synchronous servo motors are designed to meet the high requirements needed to ensure quality performance for industrial motion systems. These motors are equipped with a special flux profile and permanently fixed magnets. These usually serve to increase the servo’s response. They also feature a three-phase sinusoidal-wound stator that enables a smooth and uniform operation when the machines are operating at low speeds.

The 1326AB-B430G-21ML has an IP67 Environmental Rating that is available with an optionally installed shaft seal. With an extruded aluminum housing, this gives the device more heat transfer capabilities. This device is easy to install. This is because it can be vertically mounted at whatever angle the user chooses. The 1326AB-B430G-21ML also features a normally closed thermal switch located in its motor winding. This amazing feature provides thermal overload indication of the module. This is rated 115V AC/24V DC at 1A). It also has a threaded hole on the shaft’s face that helps in securing couplings. This module also features a precision balance of 0.0127 mm (0.0005 in.) total peak-to-peak displacement and a CEI/IEC 72-1 metric flange mount with metric shafts.
