1326AB-B420H-21-ML

The Allen-Bradley 1326AB-B420H-21-ML servo motor is a 1326AB series servo motor. This servo motor has an input voltage rating of between 380 Volts AC and 480 Volts AC. The 1326AB-B420H-21-ML servo motor has a frame diameter of 108 millimeters and a bolt center of 115 millimeters. The motor can reach a maximum speed of 6000 revolutions per minute. However, this speed is affected by the input voltage and the load on the servo motor. The 1326AB-B420H-21-ML servo motor has a Horsepower rating of 3 Horsepower and an apparent power rating of 2.2 kilowatts.

The 1326AB-B420H-21-ML servo motor, like other motors in the 1326AB series, accommodates the 1326AB planetary gearboxes which provide increased torque. The gearboxes provide a cost-effective way to increase torque, it mounts easily, and it only adds a small inline package. The gearboxes have standard features such as the twin torque-tube bearings and multiple-contact planetary design which helps in providing enhanced load carrying capabilities in a compact package. Additionally, the gearboxes have an efficiency rating of more than 90%, it has accurate and smooth output from precision gears, it is permanently lubricated to eliminate maintenance, and it has a maximum backlash of 10 arc-minutes at the output shaft. The 1326AB-B420H-21-ML servo motor, in addition to supporting planetary gearboxes, also supports the use of a holding brake. The motor is designed for factory use only. The 1326AB-B420H-21-ML servo motor has a NEMA metric flange and an environmental rating of IP 67. The servo motor, like other servo motors in the 1326AB series, has an operating non-condensing relative humidity rating of between 5 and 95%.
