1. Product Overview
Product Model: MPL-A4540F-SK72AA
Brand: Allen-Bradley
Product Series: MP-Series MPL Low-Inertia Brushless Servo Motor Series
Product Type: AC Rotary Servo Motor
Application Category: Industrial Motion Control System
The MPL-A4540F-SK72AA is a low-inertia brushless AC servo motor designed for high-precision industrial motion applications.
This model belongs to the MP-Series MPL servo motor family and is designed for equipment requiring fast response, accurate positioning, smooth speed control, and reliable continuous operation.
The motor uses a 230V AC voltage class design with a 45 frame size and a 101.6 mm magnet stack length. It provides a rated speed of 3000 RPM and approximately 10.2 Nm continuous torque output, making it suitable for medium-load automation systems that require both high dynamic performance and compact installation.
The MPL-A4540F-SK72AA uses a single-turn high-resolution encoder feedback system. This feedback configuration provides accurate position detection and supports stable closed-loop motion control.
Unlike traditional feedback systems with lower resolution, the high-resolution encoder improves positioning accuracy, motion smoothness, and repeatability, making it suitable for precision automation equipment.
This model features a keyless shaft extension, right-angle SpeedTEC DIN connector, 180° rotatable connector structure, IEC metric mounting, and no brake configuration.
The keyless shaft design simplifies mechanical integration, while the no-brake configuration reduces motor weight and is suitable for applications where external holding mechanisms are not required.
The MPL-A4540F-SK72AA is commonly applied in packaging machinery, CNC equipment, robotics, electronic manufacturing systems, material handling equipment, and automated production lines.

5. Product Introduction
The MPL-A4540F-SK72AA is a precision servo motor developed for automation systems that require accurate movement control and fast dynamic response.
The motor adopts a low-inertia rotor structure, allowing it to respond quickly to speed and position commands from the motion controller.
During repeated acceleration and deceleration cycles, the motor can quickly reach target speed while maintaining smooth operation and accurate positioning.
The single-turn high-resolution encoder provides detailed feedback information to the control system. This allows the servo drive to continuously monitor motor position and adjust operation to maintain accuracy.
The keyless shaft design provides a flexible mechanical connection method. Compared with traditional keyed shafts, it can simplify coupling installation and reduce mechanical adjustment requirements.
The no-brake structure makes this model suitable for horizontal-axis applications where the load does not require mechanical holding after stopping.
The compact 45 frame design provides a good balance between installation size and motor performance.
