1326AB-B520E-21-L

The 1326AB-B520E-21-L servo motor manufactured by Allen-Bradley as a high-performance motor. Motors in this category that have an environmental protection rating of IP 67 can be employed for use in hazardous locations and in environments that are prone to high levels of gas and dust. Additionally, the servo motor has a rugged construction with a protruding frame for cooling down and high power and torque densities. The 1326AB-B520E-21-L servo motor has legacy support for original F series devices and it features medium inertia for matching heavy-duty loads. Note that the servo motors are customized in the factory. The 1326AB series servo motors have 480 Volts AC windings and a continuous stall torque ranging from 2.7 to 53 N-m. For the feedback, the servo motors use either a resolver or a high-resolution absolute feedback encoder.

The servo cable sets used by the Allen-Bradley 1326AB-B520E-21-L servo motor are shielded to guard against electromagnetic interference. Additionally, the cables are manufactured from extremely flexible materials. The flexibility guarantees a long life for the servo motor when it is interfaced with applications that require continuous cable flexing. Moreover, the cable sets are molded to meet certain ingress protections and they are built at the required lengths which reduce costs and waste. The 1326AB-B520E-21-L servo motor has a 149-millimeter frame diameter and a 165-millimeter bolt center while its magnet stack length stands at 2 inches. While operating at 460 Volts AC, the 1326AB-B520E-21-L servo motor has a rated maximum speed of 3000 revolutions per minute. However, when operating at 380 Volts AC, the motor can reach a maximum speed of only 2500 revolutions per minute.
