4. Electronic nameplate inside motor, automatic parameter identification with Lenze servo drives
5. Wide operating temperature range, stable performance under -20°C ~ +40°C ambient
6. cURus, EAC, CE global safety certifications for worldwide equipment export
7. Optimized electromagnetic design, low torque ripple and smooth low-speed operation

Working Principle

Material & Structural Characteristics

• Motor Housing: Die-cast aluminum alloy with black anti-corrosion electrophoretic coating
• Stator Core: Laminated silicon steel sheet to reduce eddy current loss
• Rotor: High-strength steel shaft + sintered neodymium iron boron permanent magnets
• Shaft Seal: Nitrile rubber rotary shaft seal, dust and splash water resistance
• Connector Housing: Reinforced PA66 plastic, anti-vibration locking plug structure
• Cooling Structure: External radial heat sink ribs + axial self-ventilation fan integrated at rear end

Installation Requirements

1. Standard IEC flange mounting, four M8 fixing bolts evenly tightened with torque 12 Nm
2. Shaft parallelism error ≤0.05 mm when coupling with load to avoid radial bearing damage
3. Install fan side facing ventilation space, blockage of fan air inlet strictly prohibited
4. Power and feedback cables must use shielded servo dedicated cables, shield grounding at motor and drive double ends
5. Vertical mounting allowed; add auxiliary brake module separately for vertical axis load holding
6. Ambient installation height ≤1000 m above sea level; derate power by 10% for altitude above 1000 m

Application Scenarios

• High-speed packaging machine cross cutter, film stretching axis
• Printing press register adjustment and paper transport servo axes
• CNC routing machine small spindle auxiliary feed axis
• Automated assembly line pick-and-place linear motion module
• Textile machinery warp feeding and fabric tension control axes
• Injection molding machine ejection and mold clamping auxiliary servo

Operation & Maintenance Notes

1. Complete shaft alignment test before trial run to prevent premature bearing wear
2. Check fan air inlet for dust accumulation every 3 months, clean compressed air blowing allowed
3. Do not operate motor without resolver feedback connection; drive will report position fault
4. Avoid long-term continuous operation at 300% peak torque, only for short acceleration cycles
5. Lubricate front and rear bearings every 8000 operating hours with Lenze specified grease
6. Prevent chemical liquid splashing onto motor housing; IP65 only resists water spray, not full immersion
