The Allen Bradley MPL-A320P-HK72AA Servo Motor is a premium Kinetix MP-Series MPL low-inertia brushless AC servo motor engineered for demanding industrial motion control applications requiring high-speed operation, precise positioning, and reliable continuous-duty performance. As a member of the Rockwell Automation MP-Series MPL family, this servo motor integrates seamlessly with Kinetix servo drive systems, delivering accurate closed-loop control of position, speed, and torque for advanced automation equipment.
The HK72AA configuration features a 2000-line incremental encoder, a SpeedTEC right-angle 180° rotatable DIN connector, a keyless shaft extension, and no holding brake. Designed for 230 VAC servo systems, the motor incorporates a 100 mm frame size, a 50.8 mm magnet stack length, and a 5000 rpm rated speed. The keyless shaft design improves concentricity, minimizes backlash, and provides excellent torque transmission when used with precision locking assemblies.
Featuring a 100 mm frame size and an approximate weight of 3.7 kg, the MPL-A320P-HK72AA combines compact dimensions with high power density and excellent dynamic performance. Its low-inertia rotor enables rapid acceleration and deceleration while maintaining outstanding positioning repeatability and smooth torque output.
Typical applications include robotics, packaging machinery, CNC machining centers, semiconductor manufacturing equipment, electronic assembly systems, pharmaceutical production lines, material handling equipment, printing machinery, and automated manufacturing cells.
