1326AB-B720E-21

The 1326AB-B720E-21 servo motor is a 3500 RPM rated Allen-Bradley servo motor. It is designed and manufactured as part of the Allen-Bradley 1326AB series of servo motors. Applications for 1326AB series servo motors include metal forming, packing, automotive, and machine tool applications. The 1326AB-B720E-21 servo motor delivers 3000 and 3500 RPM at 380 and 460 Volts AC, respectively. Additional motor specifications include 27.3 pounds on an inch of motor torque, 6.8 kilowatts power output, and 0.14 lb-in-s2 rotor inertia. The 1326AB-B720E-21 servo motor is designed for use with Allen-Bradley 1394 motor control systems. The motor can be used with 2 different 1394 axis modules. With both the Allen-Bradley AM50 and the AM75 modules, the motor offers 273 pounds on an inch of steady-state stall torque while the maximum stall torque is 518 pounds on an inch with the AM50 module and it is 780 pounds on an inch with the AM75 module. With the AM50 and the AM75 modules, the 1326AB-B720E-21 servo motor delivers 17.5 Amps of continuous stall current while the maximum stall current is 33.2 Amps with the AM50 module and is 50 Amps with the AM75 module.

The mechanical specifications of the 1326AB-B720E-21 servo motor include a frame diameter of 194 millimeters, a 20-millimeter magnet stack length, and 102 pounds of motor weight. Also available on the servo motor are an IEC 72-1 metric flange and resolver-based feedback. Allen-Bradley recommends that the 1326AB-B720E-21 servo motor should be operated in an environment where the temperature of the air surrounding the motor does not exceed 104 degrees Fahrenheit. The motor can be mounted with the shaft facing vertically downwards or upwards. The extruded aluminum housing of the 1326AB-B720E-21 servo motor enables it to have improved heat transfer. The environmental protection rating of the motor is IP 65.
