The Allen-Bradley 1326AB-B740E-21-L servo motor is a ferrite AC servo motor. The servo motor operates with an input voltage not exceeding 460 Volts AC and not falling below 380 Volts AC. The 1326AB-B740E-21-L servo motor has a frame size with a diameter of 194 millimeters while its bolt center measures 215 millimeters. The motor uses a resolver based feedback and it has an enclosure with an ingress protection rating of IP 67. The 1326AB-B740E-21-L servo motor is shipped with standard plug-in style connectors that have an ingress protection rating of IP 65. The connectors are mounted radially to the servo motor.

The 1326AB-B740E-21-L servo motor supports a motor junction box kit. With the kit, the connectors can be brought out axially to the motor without further wiring. Note that the junction box kit contains a motor junction box and mounting hardware. The servo motor’s maximum speed is defined by the input power. For example, the 1326AB-B740E-21-L servo motor is capable of reaching a maximum speed of 3400 revolutions per minute when the input power rating is 460 Volts AC. However, when the servo motor is operated with an input power of 380 Volts AC, it is capable of reaching a maximum speed of 2800 revolutions per minute. The 1326AB-B740E-21-L servo motor has a rated torque of 50 N-m and a rated output of 12.7 kilowatts. The system continuous stall current is 32 Amps while the system peak stall current is 50 Amps. The 1326AB-B740E-21-L servo motor is rated to be mounted and operated in an environment that has an ambient temperature of up to 40 degrees Celsius and a relative humidity rating of up to 95% without condensation.
