Product Detailed Description

The Allen-Bradley MPL-B420P-HJ72AA is a high-performance, low-inertia brushless servo motor from the MP-Series™ family, designed for precise motion control in demanding industrial applications. It is a 460V AC rotary servo motor with a compact frame size of 115 mm (4.53 in.) and a magnet stack length of 50.8 mm (2.0 in.), enabling faster acceleration and high torque output in a reduced footprint. This motor features a permanent magnet rotor with high-energy rare earth magnets, advanced winding technology for up to 40% higher torque density compared to traditional servo motors, and an incremental encoder for accurate position feedback. It includes a keyed shaft extension for secure coupling, a SpeedTEC DIN connector for reliable wiring, and IEC metric mounting holes (Type FF) for versatile installation. The motor is optimized for integration with Allen-Bradley motion control systems, such as Kinetix drives, and complies with UL and CSA standards for safety and reliability.

Product Parameters

Product Advantages

• High Torque Density: Delivers up to 40% more torque per unit volume than conventional servo motors due to innovative winding technology and rare earth magnets, allowing for smaller motor sizes without sacrificing performance.
• Low Inertia Design: Minimizes rotor inertia for rapid acceleration and deceleration, ideal for high-dynamic-response applications requiring precise positioning.
• Smart Motor Technology: On-board memory retains motor identity and parameters, enabling automatic recognition and simplified commissioning in networked systems.
• Flexible Connectivity: SpeedTEC DIN connectors provide secure, vibration-resistant wiring with 180° rotatable options for easy installation in tight spaces, supporting single-cable solutions.
• Enhanced Thermal Management: Improved insulation materials promote efficient heat dissipation, supporting continuous operation in demanding environments.
• Compact and Versatile: Standard IEC 72-1 dimensions and metric mounting ensure compatibility with global standards and seamless integration into existing machinery.
• Reliability and Safety: UL/CSA certifications, robust construction, and no battery-required encoders (for similar models) reduce maintenance needs and downtime.

Precautions and Notes

• Installation Precautions: Ensure proper alignment during shaft coupling to avoid misalignment, which can cause premature wear. Use the provided Type FF mounting holes for secure attachment; torque bolts to manufacturer specifications (refer to installation manual). For motors without a shaft seal (like this model), apply an optional shaft seal kit (e.g., MPL-SSN-A4B4) in environments with potential contaminant ingress to prevent damage.
• Electrical Warnings: Connect only to compatible Allen-Bradley drives (e.g., Kinetix 2000/6000/7000 or Ultra 3000 series) rated for 460V AC. Verify grounding and shielding to minimize electromagnetic interference (EMI). Do not exceed peak current ratings to avoid overheating.
• Environmental Notes: Operate within 0…40°C (32…104°F) ambient temperature and 5…95% non-condensing humidity. Avoid exposure to corrosive substances, excessive vibration (>5g), or altitudes above 1000 m without derating. Store in a dry, dust-free environment at -40…70°C.
• Maintenance and Safety: Disconnect power before servicing. Inspect connectors periodically for secure seating; M58-style connectors (if applicable in series) require physical repositioning in 90° increments for orientation. No user-serviceable parts inside—contact Rockwell Automation for repairs. Follow lockout/tagout procedures during installation to prevent accidental energization.
• General Warning: This motor is intended for industrial use only. Improper handling may void warranty. Consult the full installation instructions (Publication MP-IN001) for detailed wiring diagrams and commissioning steps.

Product Applications

The MPL-B420P-HJ72AA is suited for high-precision, high-speed motion control in various industrial sectors, including:

• Packaging Machinery: For rapid indexing, filling, and sealing operations requiring accurate servo positioning.
• Material Handling: In conveyor systems, pick-and-place robots, and automated guided vehicles (AGVs) for smooth acceleration and load handling.
• Machine Tools: CNC routers, lathes, and mills benefiting from low-inertia response for fast tool changes and contouring.
• Printing and Converting: High-speed web handling, die cutting, and registration control in presses and rewinders.
• Food and Beverage: Hygienic automation for sorting, capping, and labeling, where compact size and reliability are critical.
• General Automation: Integration with PLC-based systems for assembly lines, electronics manufacturing, and semiconductor handling, leveraging compatibility with Kinetix and Ultra drive families for synchronized multi-axis control.
