Product Overview

The Allen-Bradley MPL-B4560F-SJ72AA is a high-performance, brushless AC rotary servo motor engineered for the Kinetix motion control platform. As part of the MP-Series (Low Inertia) family, this motor is specifically designed to meet the rigorous demands of high-cycle industrial applications where rapid acceleration and precise deceleration are critical. Operating on a 460V AC power class, the motor features a 130 mm frame size and a 152.4 mm (6-inch) magnet stack, delivering a rated speed of 3,000 RPM. Its low-inertia rotor design allows for superior responsiveness, making it a foundational component for synchronized multi-axis motion systems.

Technical Characteristics

The MPL-B4560F-SJ72AA is defined by its precision feedback and robust mechanical architecture:

High-Resolution Optical Feedback Equipped with a single-turn high-resolution optical encoder, the motor provides 1,024 SIN/COS cycles per revolution. This high-fidelity feedback ensures absolute positioning accuracy and smooth velocity control when integrated with Kinetix 5500, 5700, or 6000 series drives.

Advanced Connection and Mounting The unit features a SpeedTec DIN connector that is 180-degree rotatable, providing maximum flexibility for cable routing in tight enclosures. It is built with an IEC metric mounting flange and a keyed shaft output, ensuring a secure mechanical interface for pulleys, gearheads, and couplings.

Thermal and Magnetic Efficiency Utilizing innovative winding technology and high-energy rare-earth magnets, the motor achieves exceptional torque density in a compact form factor. This brushless design reduces internal friction and heat generation, extending the operational life of the internal ball bearings and windings during continuous duty cycles.

Industrial Durability The motor housing is designed for rugged industrial use, featuring an IP50 rating (standard) or higher with the addition of a shaft seal. Its brakeless configuration is optimized for applications where the drive control handles the stopping logic, further reducing the overall weight and mechanical complexity of the unit.
