* The Allen Bradley 1326AB-B2E-21-A5 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B2E-21-A5 units instead of migration.
The 1326AB-B2E-21-A5 servo motor is a brushless servo motor manufactured by Allen-Bradley/Rockwell Automation as part of the 1326AB AC servo motor series and it is designed and intended for factory use only. The frame size of this servo motor measures 5.88 inches or 149 millimeters, and it has a frame stack length of 2. It has a motor rated speed of 3000 to 4000 RPM with a NEMA, IEC metric flange with a keyway option. Also, this brushless servo motor features a holding brake of 120 pounds on an inch or 13.6 N-m with a DC coil of 90 Volts. These motors are designed to help achieve high performance and enhance smooth operations. The entire series, including the 1326AB-B2E-21-A5 servo motor, is compatible and can be used with Allen-Bradley 1394 motion control systems or the ULTRA series operating on 460 Volts or 2098-HV.
The feedback options for the 1326AB-B2E-21-A5 servo motor and the whole 1326AB brushless servo motor series include a resolver of 4096 count revolutions. There is also a high-resolution absolute single-turn feedback option of up to 2 million counts per revolution, a smart motor functionality, and absolute single turn capability in 1 revolution. The third feedback option is the absolute multi-turn high resolution, with the smart motor feature, up to 2 million counts per revolution, and absolute feedback in more than 4096 revolutions. These motors are intended for use in applications requiring consistent high output and seamless operation. They are used in the automotive, packaging, machine tool, metal forming, and material handling. Additionally, the 1326AB servo motors come with a NEMA, IP 67 enclosure rating intended to offer protection from the harsh environments that the motors are used in. They feature an advanced magnet design that has magnet flux alignment to increase the flux density, strengthen demagnetization protection, and reduce harmonics as well as losses.
