Product Overview
The Allen-Bradley MPL-A310F-HK74AA Servo Motor is a premium MP-Series Low-Inertia Brushless AC Rotary Servo Motor designed for demanding industrial motion control applications. As part of the Rockwell Automation MP-Series servo motor family, this model combines fast dynamic response, precise positioning, and dependable torque output to meet the requirements of modern automation systems.
The MPL-A310F-HK74AA 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 keyless shaft extension, a SpeedTEC right-angle 180° rotatable DIN connector, and an integrated 24 V DC electromagnetic holding brake. The keyless shaft design simplifies coupling installation while the holding brake securely maintains shaft position whenever servo power is removed.
Designed for seamless integration with Allen-Bradley Kinetix servo drive systems, the motor provides accurate position, speed, and torque control while ensuring excellent repeatability and smooth motion. The low-inertia rotor minimizes response time, making it suitable for high-speed automation equipment requiring precise motion control.
With a 100 mm frame size and an approximate weight of 2.7 kg, the MPL-A310F-HK74AA is widely used in robotics, packaging machinery, CNC equipment, semiconductor manufacturing, material handling systems, printing equipment, and automated production lines.
