Allen Bradley 1326AB-B3E-21

The 1326AB-B3E-21 is an efficient 3-phase servo motor manufactured by Allen-Bradley to fulfill the stringent requirements of critical motion systems. This servo motor, which belongs to the Torque Plus Series, features a specially designed housing that shrinks motor length and boosts continuous torque ratings. This 40 Volt AC servo motor is uniquely designed to be used with the 1394 Motion Control System. Each part incorporates special flux permanent magnets to improve servo response, TENV construction, an extruded aluminum cover for better heat transfer, a 3-phase, sinusoidal-wound stator field to boost smooth operation, a thermal switch (rated 115 Volts AC to 24 Volt DC) which offers thermal overload indication, and an AUL listed insulation system. The 1326AB-B3E-21 servo motor comes with either standard resolver or high-resolution encoder systems. Resolver-based designs that generate 2048 ppr encoder output are furnished with a brushless resolver which provides precise position feedback, withstands high operating temperatures and harsh shock, and eliminate the necessity of onboard electronics. High-resolution servo motors, on the other hand, are obtainable in single or multi-turn designs that provide exceptional encoder feedback for stringent applications requiring accurate tolerance.

Considering other motor servos performing the same purpose, the 1326AB-B3E-21 has the features to make it a valuable industrial investment. The single-turn configuration offers accurate machine positions of 2 million counts/revolution while the multi-turn configuration provides perfect machine positions over numerous revolutions to prevent machine re-homing from active power. It provides 1 million feedback counts/revolution and accurate positioning within 4,096 revolts. The two configurations have a built-in EEPROM memory that helps with the storage of motor configuration information. Belonging to the Torque Plus Series, the 1326AB-B3E-21 comes with multiple servo motor options, including spring-set holding brakes featuring 24 Volt DC coils (-K7, -K5, and-K4) and a shaft oil seal gear for installing an oil shaft on a running motor. It isn’t always necessary to disassemble the motor while this is being done. Installing the shaft oil seal helps keep the motor dust tight, tolerant to pulsating water jets, and able to meet the IP65 standard (IEC 529) requirements. When using the 1326AB-B3E-21 drive with a 1394 Servo System, a secondary encoder will not need to be installed, since these drives derive an output feedback of 2048 from the motor’s feedback. When an externally fitted encoder package is utilized, the 1326AB servo motors tend to lose their IP65 or IP67 rating.

A Junction Box set with axially-mounted comes with front/exit connections. The unit also has right-angled connector cables. With the junction box, motor connectors should be brought out axially instead of radially. The 1326AB-B3E-21 loses its IP rating when the optional junction kit is utilized. The 1326AB-B3E-21 catalog numbers are comprised of various modules. Each character identifies a specific option for that particular component. With the 1326AB-B3E-21, users benefit from enhanced system performance, great product functionality, advanced diagnostics, improved accuracy, ease of installation and maintenance, increased flexibility and decreased downtime.  In a nutshell, this brushless AC synchronous motor drive comes with high-tech features that make it versatile for almost all industrial applications.
