Product Lifecycle Status*Discontinued/Obsolete

* The Allen Bradley 1326AB-B430E-21-K7 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B430E-21-K7 units instead of migration.

The Allen-Bradley 1326AB-B430E-21-K7 servo motor is a 1326 series servo motor. It is a high-performance device which works with a servo. The 1326AB-B430E-21-K7 servo motor is a 3-phase device that is also known as a brushless AC synchronous motor. All the servo motors from the 1326 series are equipped with permanent magnet rotors which help to increase the servo’s response. The 1326AB-B430E-21-K7 servo motor can be operated with a minimum temperature of 0 degrees Celsius and a maximum temperature of 40 degrees Celsius. The device can be stored in a clean environment with relative humidity between 5 and 95% when not in use. The storage area should be free from dust, dirt, and other corrosive vapors. Electromagnetic noise should not be present in the installation area of the device. Such noise reduces the performance of the servo motor.

The 1326AB-B430E-21-K7 servo motor is manufactured with the TENV construction. The housing of the device comes inside a 108-millimeter frame with a bolt center that measures 115 millimeters. The servo motor can be mounted with the shaft pointing up or down by using the IEC metric flange that is included by the manufacturer. The device has a precision balance of 0.0127 millimeters with the total peak displacement. The 1326AB-B430E-21-K7 servo motor has been recognized by the UL standards for its insulation system. The servo motor comes with an integral holding brake with a 24 Volts DC coil. The brake has been designed to hold any given load at rest and provide limited braking torque for emergency stopping purposes. The servo motor is equipped with a resolver-based feedback device which tracks the operation of the servo motor and then sends the information to the users. The servo motor can be operated with both 460 Volts AC and 380 Volts AC voltage. The rated speed of the servo motor is determined by the amount of voltage that is applied.
