1. Product Overview

Product Model: MPL-A4540F-HK72AA

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-HK72AA is a high-performance low-inertia brushless AC servo motor designed for precision motion applications. It is part of the MP-Series MPL servo motor family and is mainly used in industrial automation systems that require fast response, accurate positioning, smooth operation, and reliable continuous performance.

This servo motor is designed for 230V AC class operation and features a compact 45 frame size with a 101.6 mm magnet stack length. The motor provides a rated speed of 3000 RPM and uses an incremental encoder feedback system for accurate motion monitoring and control.

The MPL-A4540F-HK72AA adopts a low-inertia rotor design, which allows the motor to achieve rapid acceleration and deceleration. This feature makes it especially suitable for machines with frequent movement cycles, high-speed indexing operations, and applications where positioning accuracy is important.

The motor configuration includes a 2000-line incremental encoder, keyless shaft extension, right-angle SpeedTEC DIN connector, 180° rotatable connector structure, and no mechanical holding brake. This configuration is commonly selected for horizontal-axis motion applications where fast response and compact installation are required.
