Overview
The Allen-Bradley MPL-A1530U-HJ44AA is a compact 63 mm frame, low-inertia brushless servo motor from Rockwell Automation’s MP-Series family. Rated for 200V operation, this motor achieves 7000 RPM maximum speed with 0.39 kW continuous power output and 0.90 N·m continuous stall torque. The HJ44AA configuration includes a HIPERFACE absolute multi-turn encoder for high-resolution position feedback, shaft key mounting, and SpeedTec-ready DIN connectors for streamlined integration into Kinetix-based motion control systems.
Key Features
- High Torque-to-Size Ratio: Compact 63 mm frame delivers 0.90 N·m continuous stall torque in a small footprint, ideal for space-constrained applications requiring fast acceleration.
- Absolute Feedback with HIPERFACE Encoder: Multi-turn absolute feedback provides 260,000+ counts per revolution for smooth, precise position control without initialization.
- 200V AC Rated: Standard industrial AC voltage with 2.0 A continuous current, 7.1 A peak stall current for flexible drive compatibility.
- Advanced Winding Technology: High-energy rare-earth permanent magnets and improved thermal management windings deliver superior performance and reliability in demanding motion applications.
- SpeedTec DIN Connectors: 180-degree rotatable connectors enable quick one-quarter-turn connections for fast installation and field serviceability.
- Kinetix Drive Compatibility: Integrates directly with Allen-Bradley Kinetix 350, 6000, 7000, 6500, 6520, and Ultra3000 servo drive families.

Typical Applications
The MPL-A1530U-HJ44AA excels in precision motion control requiring high acceleration and compact form factor. Common applications include electronics assembly machines, converting equipment, packaging machinery, automotive production systems, material handling automation, and positioning applications where low inertia and fast response times are critical. The HIPERFACE absolute feedback makes it ideal for multi-axis coordinated motion systems that demand reliable commutation across power cycles.
Compatibility & Replacements
The MPL-A1530U-HJ44AA is compatible with Allen-Bradley Kinetix servo drives including the Kinetix 350, 6000, 7000, 6500, 6520, and Ultra3000 families. The motor requires appropriate power wiring and motion control cables (sold separately) compatible with SpeedTec DIN connectors. For applications requiring different feedback types, Rockwell Automation offers alternative MPL-A1530U configurations with incremental encoders or resolver feedback. The Series A specification aligns with current MP-Series technical documentation (Publication MP-PP001 and MP-IN006). Consult Rockwell Automation distributors or technical support for drop-in replacement guidance specific to your Kinetix drive version and firmware revision.
