The Allen-Bradley 1326ABB730E-21-K7L Torque Plus Servo Motor is a high-performance 3-phase, brushless AC synchronous motor with a permanent magnet rotor which is designed to meet the stringent requirements of industrial servo applications. This resolver-based servo motors in the 1326AB family of high-performance servo drives feature a 3-phase sine-coded wound stator field for smooth operation, with a rugged brushless resolver which provides communication and velocity feedback information, and this servo motor is capable of providing 100% torque even at a stall (0 RPM). The 1326ABB730E-21-K7L has a nominal 3-phase AC input voltage of 460 Volts AC, with minimum and maximum acceptable voltage range of 380 to 460 Volts AC, and it has a maximum output power rating of 9.6 KiloWatts. This motor has a system stall current of 22.8 Amps, which peaks at 50.0 Amps, and it has a rated rotor speed of 2800 RPM at 380 Volts AC and 3350 RPM at 460 Volts AC.
The 1326ABB730E-21-K7L has a rated motor torque of 39.0 N-m, with a peak system stall torque of 85.4 N-m, and it has rotor inertia value of 0.024 Kg-m2. It has 9.6 milliseconds mechanical time constant, with 11.92 milliseconds electrical time constant, and it has a rated thermal constant of 60 minutes with Class H Rated Thermal Insulation. The 1326ABB730E-21-K7L has a winding resistance of 0.426 Ohms, with a winding voltage of 126.2 Volt per 1000 RPM, and it has a 2.01 N-m winding torque. This servo motor is designed with a rugged brushless resolver feedback device which provides accurate position feedback, and it has an integral holding brake option with a 24 Volts DC coil, and a holding brake torque of 41 N-m. It has an IP67 rated industrial enclosure, with a 194 millimeters frame diameter and a 30 millimeters magnetic stack length, and it has an IEC-rated flange mounting option with a keyway. The 1326ABB730E-21-K7L weighs approximately 62.6 kilograms (with a holding brake), and it has total dimensions of 207.5 x 514.7 x 173.6 millimeters.
