5. Straight shaft with keyway design enables convenient coupling installation and stable torque transmission.

6. Brushless motor structure features low running noise, no carbon brush wear and long service life, maintenance-free under normal working conditions.

7. Fanless natural air cooling structure reduces failure points, lowers operation noise and improves overall equipment reliability.

6. Application Scope

• 400V grade CNC lathes, milling machines and machining center medium-load feed axes

• High-voltage industrial automation production line medium-load positioning and transmission mechanisms

• Packaging machinery, printing machinery, textile machinery and general industrial equipment

• Servo systems requiring long-distance wiring and low current loss

• Horizontal installation axes and non-suspended load equipment without anti-fall brake requirement

7. Installation Guidelines

1. Install the motor on a rigid, flat and non-deformable mounting base to avoid resonance and mechanical stress deformation.

2. Maintain precise coaxial alignment between motor shaft and load shaft to reduce vibration, noise and premature bearing wear.

3. Use dedicated shielded high-voltage servo power cable and encoder cable; separate power wiring and signal wiring to reduce electromagnetic interference.

4. Reserve sufficient surrounding space for natural heat dissipation; do not cover or block the motor housing heat dissipation area.

5. Avoid strong impact, dropping and extrusion on motor body and encoder rear cover during handling and installation.

8. Maintenance Instructions

1. Regularly inspect motor running status including abnormal noise, vibration and temperature rise.

2. Keep motor surface clean, remove dust, metal chips and oil contamination periodically.

3. Built-in sealed bearings adopt lifetime lubrication, no regular refueling maintenance required under normal working conditions.

4. Inspect encoder cable integrity, connector fastening and aging status at regular intervals.

5. Avoid long-term overload operation and frequent forward and reverse start-stop beyond allowable load range.

9. Safety Precautions

1. Cut off all 380–400V high voltage power supply before installation, wiring and maintenance. Wait at least 15 minutes for internal capacitor discharge to prevent electric shock hazard.

2. Do not touch rotating shaft and moving parts during motor running state.

3. This model has no holding brake; it is forbidden to apply to vertical axis or suspended load with falling risk without additional mechanical locking device.

4. Do not disassemble motor and encoder privately; unauthorized disassembly will void warranty and damage assembly precision.

5. Do not use the motor in environment with conductive dust, heavy moisture condensation and chemical corrosion without special protection.

10. Troubleshooting

• Motor fails to start: Check 3-phase 400V power supply, wiring tightness, servo amplifier alarm code and servo enable signal.

• Abnormal noise and vibration: Check mounting rigidity, coupling alignment, bearing aging and mechanical load jamming.

• Motor overheating: Inspect long-term overload, ambient temperature over limit and poor ventilation.

• Positioning deviation out of tolerance: Check encoder cable breakage, loose connector, servo parameter mismatch and mechanical transmission backlash.

• Unstable speed: Verify power supply voltage fluctuation, sudden load change and encoder signal interference.
