The Allen-Bradley MPL-A310F-HJ74AA Servo Motor is a high-performance MP-Series Low-Inertia Brushless AC Rotary Servo Motor designed for demanding industrial motion control applications. As a member of the Rockwell Automation MP-Series servo motor family, this motor delivers precise positioning, stable torque output, and rapid dynamic response for high-speed automated machinery.
The MPL-A310F-HJ74AA features a 230 V AC voltage class, a 100 mm IEC metric frame size, a 25.4 mm magnet stack length, a 3000 RPM rated speed, a 2000-line incremental encoder, a keyed shaft, a SpeedTEC right-angle 180° rotatable DIN connector, and an integrated 24 V DC electromagnetic holding brake. This configuration is particularly suitable for vertical-axis applications where reliable load holding and accurate motion control are required.
Designed for seamless integration with Allen-Bradley Kinetix servo drive systems, the motor provides highly responsive closed-loop position, speed, and torque control. The low-inertia rotor minimizes settling time, enabling faster machine cycles while maintaining excellent positioning repeatability.
With a 100 mm frame size and an approximate weight of 2.7 kg, the MPL-A310F-HJ74AA is widely used in robotics, CNC machine tools, packaging machinery, semiconductor manufacturing, printing equipment, material handling systems, and automated production lines.
