* The Allen Bradley 1326AB-B530E-21MK5 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1326AB-B530E-21MK5 units instead of migration.
The 1326AB-B530E-21MK5 servo motor is an AC servo motor from Allen-Bradley. The servo motor has a holding brake with a torque of 126 pounds on an inch. Additionally, the brake has a rated input power of 24 Volts DC. Unless the system power is interrupted, the holding brake should not be used as a stopping brake. The 1326AB-B530E-21MK5 servo motor has a continuous stall torque of 159 pounds on an inch and a peak stall torque of 480 pounds on an inch. For the current, the motor’s rated current stands at 13.4 Amps. The 1326AB-B530E-21MK5 servo motor has a horsepower rating and an apparent power rating of 5.6 Horsepower and 4.2 kilowatts, respectively. The 1326AB-B530E-21MK5 servo motor belongs to the Allen-Bradley 1326AB series of servo motors that are used to run high-performance motion systems. The motor’s winding has a phase to phase resistance of 1.6 ohms at plus or minus 15%.
Note that the resistance is calibrated when the 1326AB-B530E-21MK5 servo motor is subjected to an ambient temperature of 25 degrees Celsius with an allowance of plus or minus 5 degrees Celsius. Additionally, the phase-to-phase winding inductance for the 1326AB-B530E-21MK5 stands at 16.4 milliHenrys. The motor has a dielectric rating of 1500 Volts AC at a frequency of 50 to 60 Hertz for 1 minute for power leads to the ground. The 1326AB-B530E-21MK5 servo motor has maximum operating and storage temperatures of 40 degrees Celsius and 70 degrees Celsius, respectively. Also, the minimum operating and storage temperatures for the 1326AB-B530E-21MK5 servo motor stand at 0 degrees Celsius and -30 degrees Celsius, respectively. To avoid fatal injuries from short-circuits, the servo motor should not be operated in environments with condensing humidity.
