Product Overview
The Allen Bradley MPL-A1530U-EJ72AA Servo Motor is a high-performance Kinetix MP-Series MPL low-inertia AC servo motor developed by Rockwell Automation for precision industrial motion control applications. Featuring a 63 mm frame size and a larger magnet stack than the MPL-A1520 series, this servo motor delivers increased continuous torque, rapid acceleration, excellent positioning accuracy, and superior dynamic response for demanding automation systems.
As a member of the Allen-Bradley MP-Series MPL family, the MPL-A1530U-EJ72AA is engineered 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 single-turn high-resolution absolute encoder, a keyed shaft extension, a SpeedTEC right-angle 180° rotatable quick-connect connector, and no holding brake, making it suitable for high-speed motion applications where external braking is not required.
Its low-inertia permanent magnet rotor enables rapid response to command changes while minimizing settling time and improving machine productivity. The compact mechanical design allows installation in equipment with limited mounting space while maintaining reliable long-term performance.
With a 63 mm frame size and an approximate weight of 1.6 kg, the MPL-A1530U-EJ72AA is widely used in robotics, CNC machine tools, packaging equipment, semiconductor manufacturing, electronics assembly, pharmaceutical machinery, material handling systems, and high-speed automated production lines.
