2. Product Introduction

Machine tools and high-speed automated assembly lines subject drive actuators to aggressive cutting fluid mists, extreme thermal cycling, and relentless multi-axis vibration. Maintenance engineers specify this heavy-duty synchronous servo motor to maintain high dynamic response under continuous industrial loading. (—which is crucial for avoiding unexpected downtime on high-throughput metal-cutting machinery.)

Physical integration involves bolting the flanged housing directly to precision-machined machine tool beds, utilizing high-tensile fasteners to manage peak acceleration torque. The totally enclosed surface-cooled structure features an integrated IP65-rated sealing system, protecting the internal stator windings and high-resolution feedback electronics from liquid ingress and metal chip accumulation.

4. Global Compliance & Industry Certifications

Compliance auditors require explicit documentation verifying that heavy industrial drives meet international safety and environmental standards. This motor design aligns with strict global regulatory frameworks.

  • CE Mark: Confirms compliance with European Low Voltage and Electromagnetic Compatibility directives.

  • UL / cUL Recognition: Validates electrical insulation and safety standards for North American industrial machinery.

  • ATEX / IECEx: Certified for operation in designated non-sparking hazardous areas where explosive vapors or gases may be present.

  • EAC / RoHS: Satisfies Eurasian conformity and restriction of hazardous substances mandates.

Audit Note: The IP65 environmental seal integrity combined with certified non-sparking construction prevents external ignition risks in wet or volatile production zones. Verify specific lot certifications with OEM.

5. Long-Term Storage & Asset Preservation Guide

Industrial servo motors sitting idle in warehouse stock require structured intervention to prevent mechanical seizure and winding insulation breakdown. Follow these preservation directives:

  • Shaft Rotation Protocol: Manually rotate the output shaft through several complete revolutions every three months to redistribute bearing grease and prevent micro-fretting corrosion on the internal ball races.

  • Moisture Protection: Keep storage facility relative humidity below 60% and insert active desiccant packs inside the packaging crate to protect the unpainted shaft extension and connector pins from oxidation.

  • Corrosion Defense: Inspect the protective anti-corrosion coating on the shaft stub periodically, reapplying approved preservation oil if minor surface blemishes appear.

6. Physical Installation Prerequisites

  • Clearance Requirements: Allow a minimum of 100mm surrounding the motor housing to facilitate natural thermal radiation and prevent heat pooling around the feedback connector.

  • Mechanical Alignment: Couple the smooth shaft to the load using precision backlash-free clamping mechanisms, ensuring radial runout stays well within micrometer tolerances to protect internal bearings from premature side-load wear.

7. Buyer’s FAQ (Logistics & Compliance Focus)

  • Q: What Harmonized System (HS) Tariff Code governs international customs clearance for this servo motor?

    • A: This industrial AC motor typically clears under HS code 8501.52 (AC motors, multi-phase, of an output exceeding 750W), subject to local customs broker verification.

  • Q: Does importing this drive component require explicit Country of Origin (COO) documentation?

    • A: Yes. Commercial shipping invoices must clearly state the exact manufacturing country of origin to satisfy preferential trade pacts and avoid port-of-entry customs holds.

  • Q: Does this specific part number include a keyed or unkeyed shaft design?

    • A: The suffix code “NN” indicates a smooth shaft execution without a keyway, which requires a friction-clamp style coupling mechanism.

  • Q: Is comprehensive cargo insurance required during international freight transit?

    • A: Absolutely. Secure full-value transit insurance to protect against heavy shock and handling damage inherent in moving heavy industrial machinery.
