Product Overview
The Allen-Bradley MPL-A310P-MK74AA Servo Motor is a high-performance 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 delivers exceptional positioning accuracy, fast dynamic response, and reliable torque output for high-speed automated manufacturing systems.
The MPL-A310P-MK74AA features a 230 V AC voltage class, a 100 mm IEC metric frame size, a 25.4 mm magnet stack length, a 5000 RPM rated speed, a multi-turn high-resolution absolute encoder, a keyless shaft extension, a SpeedTEC right-angle 180° rotatable DIN connector, and an integrated 24 V DC electromagnetic holding brake. The multi-turn absolute encoder preserves position information through multiple shaft revolutions, eliminating the need for homing after power restoration, while the integrated brake securely holds the load whenever servo power is removed.
Designed for seamless integration with Allen-Bradley Kinetix servo drive systems, the motor provides accurate closed-loop position, speed, and torque control. Its low-inertia rotor enables rapid acceleration and deceleration while maintaining outstanding motion stability and repeatability in demanding industrial environments.
With a 100 mm frame size and an approximate weight of 2.7 kg, the MPL-A310P-MK74AA is widely used in robotics, CNC machining centers, semiconductor manufacturing, packaging machinery, printing equipment, electronics assembly, material handling systems, and automated production lines.
