Allen Bradley 1326AB-A420E-21

The Allen-Bradley 1326AB-A420E-21 AC Servo Motor is a high-performance, three-phase, synchronous motor from the 1326AB servo motor family. These servo motors are compatible with Allen-Bradley 1391 AC servo controllers. The 1326AB-A420E-21 comes with NEMA/IEC metric flange with a keyway. Its operating current at a continuous torque is 7 Amps. It has 1 kilowatt of motor rated output, 4.5 N-m (40 pounds on an inch) of system continuous torque, and a 108-millimeter of frame diameter.  There are two thermal switches wired in series in the motor winding that will open in an over-temperature condition. They are set to open at 150 degrees Celsius and close at 90 to 100 degrees Celsius. This AC servo motor has ferrite magnets that are used for cost-effective performance. The motor’s maximum operation speed and rated motor speed is 3000 rpm.

The 1326AB-A420E-21 servo motor has standard MIL-spec connectors and TENV construction. Its brushless resolver supplies position, commutation, and velocity feedback Information. It is specifically designed for factory use. The 1326AB-A420E-21 servo motor is IP 65 rated and it is suitable to function in harsh and extreme environments. It is not suitable for hazardous or explosive environments. But when it is not used with a shaft seal option (when externally mounted encoder/resolver feedback or blower packages are used), the motor loses its IP 65 rating. This high-performance servo motor is useful for applications where position control is critical. Its precision balance is 0.0005 inches (0.0127 millimeters) for total peak-peak displacement. These servo motors can be used for a variety of applications such as motion control, conveyor based applications, material handling, and advanced manufacturing while maintaining highly accurate position control.
