Furthermore, the magnet stack length is 20 millimeters. This servo motor also includes an IEC metric flange. Typical applications for the 1326AB-B520E-21 servo motor are packaging, automotive, machine tool, and converting applications. Feedback is provided through an onboard resolver. The environmental protection rating of the 1326AB-B520E-21 servo motor is IP 65.

The 1326AB- B520E-21 is an AC servomotor that is manufactured by Allen-Bradley. This product is particularly a 460V AC Servomotor that belongs to the Torque Plus series. This servo motor is capable of high-resolution motion / position control with the use of high-resolution encoder feedback. The Torque plus series of Allen-Bradley is designed with a housing that is intended to reduce the motor length while increasing the torque output. This AC servo motor is a 3-Phase, Brushless, synchronous motor which features special flux profile permanent magnets that improves the servo motor’s response, 3-Phase, sinusoidal-wound stator that enables the motor to operate smoothly even at low speeds and an IP65 rated housing. As the part number implies, this motor has a built-in resolver feedback to provide high-performance position feedback however, this servomotor is capable of Single turn configuration to provide accurate and precise machine position with resolution of 2 Million counts / revolution. Multi-turn configuration provides accurate absolute position of machine in multiple revolutions without the need of zero positioning the motor after each power cycle. Either of these configurations are stored in the servo motor’s on-board EEPROM memory to store motor information. These capabilities are enabled with the use of High-Resolution feedback CNC. This servo motor is provided has optional add-ons to fit the required operation in the process area. Such options include Integral Spring-Set holding brakes that is installed with 24VDC coils, Shaft oil seal kit, Secondary feedback mounting kit for installation of 845H Allen-Bradley Encoder, and Junction box kit.
