Product Advantages
- High Torque Density: Delivers significantly higher torque (up to 7.91 N·m peak) in a compact 100 mm frame, reducing system size and weight while maintaining superior acceleration capabilities.
- Low Inertia Design: With rotor inertia as low as 0.000078 kg·m², it enables faster response times and smoother motion profiles, ideal for high-speed, precision tasks.
- Energy Efficiency: Rare-earth permanent magnets and optimized winding design minimize heat generation, improving overall system efficiency and extending service life.
- Flexible Integration: 180° rotatable DIN connectors and IEC metric mounting simplify installation in tight spaces; compatible with multiple Kinetix servo drive families (e.g., Kinetix 2000, 6000, 7000).
- Reliable Feedback: Integrated single-turn high-resolution encoder provides precise absolute positioning without batteries, reducing maintenance needs.
- Robust Construction: Aluminum housing for rapid heat dissipation and IP65-rated options (when sealed), ensuring durability in industrial environments.
These advantages make the MPL-B320P-SK72AA a cost-effective choice for performance-critical systems.
Precautions and Notes
- Handling: Do not lift or transport the motor by the shaft, as the protective cap may loosen, leading to potential drops, injury, or damage. Use proper lifting equipment or eyebolts on the motor housing.
- Installation: Ensure proper alignment during mounting to avoid shaft misalignment, which can cause premature wear. Verify compatibility with the servo drive and follow torque specifications for mounting bolts (e.g., M6 bolts at 10 N·m).
- Environmental: Operate within 0…40°C ambient temperature; derate power by 1.25% per °C above 40°C. Protect from excessive moisture, dust, or corrosive substances; the motor is not fully sealed without optional shaft seals.
- Electrical: Connect only to compatible Allen-Bradley drives rated for 460V AC. Ground the motor properly to prevent electrical noise. Avoid exceeding rated speeds or torques to prevent overheating or demagnetization.
- Maintenance: No user-serviceable parts; inspect cables and connectors periodically for wear. If storing for extended periods, apply rust preventive to the shaft.
- Safety: Disconnect power before servicing. UL/CSA compliance requires adherence to installation guidelines in the user manual.
Always consult the official Rockwell Automation installation instructions for site-specific precautions.
