Allen-Bradley MPL-B320P-SJ72AA MP-Series Low-Inertia Servo Motor

Product Overview

The Allen-Bradley MPL-B320P-SJ72AA is a high-performance, low-inertia brushless AC servo motor manufactured by Rockwell Automation. This specialized motion control component provides high acceleration capabilities and precise positioning across automated industrial machinery.

Functional Operation

This premium servo motor executes high-speed positioning tasks by utilizing high-energy rare-earth permanent magnets. It excels in dynamic automation setups including assembly lines, automated sorting networks, and material handling systems. The motor interfaces directly with advanced Kinetix servo drive platforms. Specifically, it supports Kinetix 5500, 5700, and 6200/6500 drive architectures. An onboard high-resolution encoder continuously streams real-time feedback to the drive system. This feedback loop ensures precise closed-loop velocity and position control during intensive operations.

Mechanical and Environmental Features

Heavy-duty manufacturing environments subject machinery to demanding physical conditions. Therefore, Rockwell Automation houses this motor in a rugged Frame Size 3 enclosure. The physical design features right-angle, 180-degree rotatable DIN connectors to facilitate flexible cable routing. Depending on the mounting configuration and the use of an optional shaft seal, the housing achieves an IP53 or IP66 environmental protection rating. This sealing prevents ingress from ambient dust and industrial fluids. Furthermore, the brushless architecture significantly lowers maintenance requirements while simultaneously increasing operational efficiency.
