MPL-A320P-SK72AA Allen‑Bradley servo motor

Description

MPL-A320P-SK72AA Allen‑Bradley servo motor

Product Dimensions：

The MPL-A320P-SK72AA is a low-inertia brushless servo motor from the MP-Series™ lineup manufactured by Allen-Bradley (a Rockwell Automation brand). It is a premium permanent magnet AC synchronous servo motor designed for high-performance motion control applications. This motor features a compact aluminum housing that provides efficient heat dissipation, enabling high power density in a small form factor. It is brushless, utilizing strong neodymium-iron-boron (NdFeB) permanent magnets for enhanced power output and reliability. The motor is rated for 230V AC operation and is optimized for use with Kinetix® servo drives, offering precise positioning, velocity, and torque control. It includes a single-turn high-resolution Hiperface® absolute encoder for feedback, a keyless shaft extension, and no built-in brake, making it suitable for applications requiring fast acceleration and deceleration without the need for holding torque at rest.

Product Parameters

The following table summarizes the key specifications of the MPL-A320P-SK72AA servo motor:

These parameters are derived from Rockwell Automation’s MP-Series documentation and product datasheets.

Product Advantages

• High Power Density: Delivers 1.3 kW of continuous power in a compact 100 mm frame, ideal for space-constrained installations while maintaining robust torque output (up to 7.91 N·m peak).
• Low Inertia Design: With rotor inertia of just 0.000078 kg·m², it enables rapid acceleration/deceleration, improving dynamic response and machine cycle times in high-speed applications.
• Efficient Thermal Management: Aluminum housing facilitates quick heat dissipation, supporting continuous operation without overheating and extending motor lifespan.
• Brushless Construction: Eliminates brushes for reduced maintenance, lower wear, and higher reliability, with strong permanent magnets providing consistent torque across the speed range.
• Flexible Integration: Features a rotatable SpeedTEC DIN connector for easy wiring and IEC metric mounting for global compatibility. The Hiperface encoder ensures precise absolute positioning without homing routines.
• Energy Efficiency: Optimized for Allen-Bradley Kinetix drives, reducing energy consumption and operational costs in automated systems.
• Compact and Lightweight: Weighs only 3.7 kg, facilitating easier installation in multi-axis setups.

Precautions and Notes

• Installation: Ensure proper alignment during mounting to avoid shaft misalignment, which can cause premature bearing wear. Use the IEC metric flange holes for secure attachment. The rotatable connector allows 180° adjustment, but for similar models (e.g., with M58 connectors), physically remove and reposition in 90° increments if needed.
• Environmental Conditions: Operate within 0–40°C ambient temperature and 5–95% non-condensing humidity. Avoid corrosive environments or exposure to dust/moisture beyond IP65 rating (add optional shaft seal for enhanced protection).
• Wiring and Power: Connect to compatible 230V AC servo drives only. Verify grounding to prevent electrical noise. No built-in brake means external stopping mechanisms are required for vertical loads to avoid freewheeling.
• Maintenance: Inspect for contamination or damage periodically. Do not exceed rated torque/speed to prevent demagnetization of permanent magnets. Storage should be in a dry, non-magnetic environment.
• Safety Warnings: Disconnect power before servicing. The motor can generate high temperatures during operation—allow cooldown before handling. Comply with UL/CSA standards for hazardous locations if applicable.
• Compatibility: This model replaces discontinued variants like MPL-A320P-SK22AA; confirm firmware compatibility with drives. Consult Rockwell Automation installation instructions for torque specifications during assembly.

Product Applications

The MPL-A320P-SK72AA is versatile for demanding motion control tasks requiring precision and speed. Common use cases include:

• Packaging Machinery: High-speed indexing, filling, and sealing operations where low inertia supports quick start-stop cycles.
• Material Handling: Conveyor positioning, pick-and-place robots, and sorting systems benefiting from accurate torque control.
• Machine Tools: CNC spindles or axes needing rapid response and high-resolution feedback for milling or engraving.
• Printing and Converting: Web tension control and registration for consistent quality in high-throughput processes.
• Assembly Automation: Multi-axis robotic arms for electronics or automotive assembly, leveraging compact size for tight spaces.
• General Industrial Automation: Any servo-driven system paired with Allen-Bradley PLCs/PACs, such as in food/beverage or semiconductor manufacturing, where energy efficiency and reliability are critical.
