HF-SN202J-S100| Mitsubishi Electric | Moteur Servo AC

Description

Optimized for high-inertia load applications requiring precise speed and position control, the Mitsubishi Electric HF-SN202J-S100 is an industrial-grade AC Servo Motor within the HF-SN Series family. This motor delivers a 2.0 kW rated output at a rated speed of 2000 r/min, making it highly effective for heavy industrial positioning tasks. Built to withstand demanding manufacturing environments, the unit features an integrated shaft oil seal (indicated by the "J" suffix) and is rated at IP67 protection, safeguarding internal windings against dust, oil mist, and moisture. It pairs seamlessly with matching Mitsubishi MELSERVO series servo amplifiers to deliver smooth torque distribution across its entire operational envelope.

Features

• High-Inertia Performance: Well-suited for machines with high load-to-motor inertia ratios, ensuring stable acceleration profiles.
• Integrated Oil Seal: Built-in mechanical oil seal prevents lubricant or coolant penetration along the motor shaft.
• IP67 Protection Class: Offers superior environmental sealing against fine particulates and direct fluid splashes.
• High-Resolution Feedback: Features native encoder feedback for strict closed-loop positioning accuracy.
• Rugged Housing Design: Heavy-duty industrial housing optimized for conductive heat dissipation.

Applications

• Material Handling Systems: Conveyors, heavy-duty transfers, and sorting systems requiring controlled acceleration.
• Packaging Machinery: Rotary indexing tables, sealing systems, and carton loaders.
• Automated Tool Changers: Precision positioning of heavy mechanical assemblies in CNC environments.
• Gantry and Cartesian Robots: High-inertia axis movements in automotive assembly lines.

Empirical Engineering Insights

Alternative Models & Compatibility

The HF-SN202J-S100 is engineered specifically for use within the Mitsubishi MR-JE control architecture (matching MR-JE-200A or MR-JE-200B amplifiers). If replacing older HF-SP series models of the same wattage, ensure mounting frame compatibility and verify encoder connector compatibility, as pin orientations may vary between older generation cables and newer S100-suffix configurations.

Application Pitfalls & Engineering Notes

To prevent premature motor bearing degradation, radial and axial load limits must strictly follow OEM specifications. Under continuous cyclic duty cycles, ensure that the mechanical mounting surface behaves as an effective thermal heatsink (ideally a 300 mm x 300 mm x 12 mm steel plate or larger). Insufficient heat dissipation will elevate internal coil temperatures, leading to a thermal overload alarm (AL.50 or AL.51) on the matching drive.

Commissioning & Wiring Tips

When routing cables in environments prone to coolant or water splash, always install a drip loop before the cables enter the motor connectors. Even with an IP67 rating, constant liquid accumulation at the cable entry point can seep past the seals over extended operational periods. Ensure encoder cables are shielded and routed separately from the high-voltage motor power cables to mitigate high-frequency electromagnetic interference.
