Product Overview
The Allen Bradley MPL-A1530U-HJ74AA Servo Motor is a high-performance Kinetix MP-Series MPL low-inertia AC servo motor engineered by Rockwell Automation for demanding industrial motion control applications. Designed with a 63 mm frame size, this compact servo motor delivers exceptional positioning accuracy, fast acceleration, stable torque output, and outstanding dynamic response, making it ideal for high-speed automation equipment and precision manufacturing systems.
As a member of the Allen-Bradley MP-Series MPL family, the MPL-A1530U-HJ74AA is designed for seamless integration with Kinetix servo drives, providing accurate closed-loop control of speed, torque, and position. This model features a 230 V AC voltage class, a 7000 RPM rated speed, a 76.2 mm magnet stack, a 2000-line incremental encoder, a keyed shaft extension, a SpeedTEC right-angle 180° rotatable quick-connect connector, and an integrated 24 V DC holding brake. These features make it particularly suitable for vertical-axis applications and machinery requiring secure load holding after power removal.
The low-inertia permanent magnet rotor minimizes settling time while maximizing positioning repeatability and machine productivity. Its compact construction allows installation in equipment where mounting space is limited while maintaining reliable long-term operation.
With a 63 mm frame size and an approximate weight of 1.6 kg, the MPL-A1530U-HJ74AA is widely used in robotics, CNC machine tools, packaging machinery, semiconductor manufacturing, electronics assembly, pharmaceutical equipment, automated material handling systems, and precision production lines.
