1326AB-B740C-21-K7

The Allen-Bradley 1326AB-B740C-21-K7 is an AC servo motor from Torque Plus series. This servo motor can be supplied with 380 or 460 Volts AC of three-phase voltage. It rotates with 2200 Revolutions Per Minute when connected to 480 Volts AC and with 1800 RPM when connected to 380 Volts AC. It is engineered to save space with its reduced length housing. With the 1326AB-B740C-21-K7, smaller housing does not mean reduction of a torque. This servo motor with a small 194 millimeter (5.88 inches) frame diameter has a 53.0 N-m (469 pounds on an inch) rated torque. It produces 8.7kW at its output and it can be mounted over an IEC Metric Flange. This module also has a keyway on its shaft and it can be mounted either horizontally or vertically or at any angle. The 1326AB-B740C-21-K7 features 45.2 N-m (400 pounds on an inch) holding brake (spring-set). This holding brake is actuated with a 24 Volt DC voltage. The 1326AB-B740C-21-K7, like all bulletin 1326 servo motors, has a brushless resolver at the back part of its housing. This resolver is integrated inside the motor in order to ensure durability in tough environments. The resolver supplies position feedback information to the 1391-DES AC Servo Drive with a 2048 ppr resolution. The Allen-Bradley 1326AB-B740C-21-K7 is IP65 enclosed. There are two thermal switches inside of its housing. They are connected in series for alarming purposes if motor’s internal temperature goes over 155 degrees Celsius (311 degrees Fahrenheit). The servo motor is shipped with the approximate weight of 14.5 kilograms. The item’s dimensions are 498.2 millimeters (19.61 inches) x 207.5 millimeters (8.17 inches) x 207.5 millimeters (8.17 inches).
