The Allen-Bradley 1326AB-B730E-M2K7L is a high-performance brushless AC servo motor designed for demanding applications. Featuring a 30 mm magnet stack and 194 mm frame diameter, it operates on 3-phase input at either 460 Volts AC or 380 Volts AC, with rated speeds of 3350 RPM and 2800 RPM, respectively. The motor integrates a multi-turn high-resolution encoder and a 140 pounds-per-inch holding brake powered by a 24 Volts DC coil. It boasts an IP67-rated enclosure with a preinstalled shaft oil seal kit and can operate in environments up to 104 degrees Fahrenheit. With a power output of 9.6 kW, the motor demonstrates strong performance metrics, including a torque constant of 2.01 N-m and a voltage constant of 126.2 RMS at 77 degrees Fahrenheit. When paired with the AM50 axis module, it achieves a peak stall current of 33.2 Amps and delivers a peak stall torque of 502 pounds-per-inch, while the AM75 module elevates these ratings to a peak current of 85.4 Amps and a peak torque of 756 pounds-per-inch.
