Humidity: 10%–90% (non-condensing).
Altitude: ≤1000 m (no power derating).
Vibration resistance: Up to 5G (machine tool compatible).
6. Main Product Features
High-speed performance: 3000 rpm rated speed, ideal for high-feed machining.
Medium-inertia rotor: Balances dynamic response and stability for frequent start/stop and reversing.
Alpha A64 absolute encoder: High precision, no external battery needed, supports power-on homing-free operation.
Brake-free design: Lower cost and lighter weight for horizontal-axis applications.
Standard IP54 sealing: Protects against dust and light coolant splash for general workshops.
Fanless cooling: Reduces maintenance and failure risk.
Amplifier compatibility: Fully compatible with FANUC Alpha i-B series servo amplifiers (e.g., SVM1-130).
7. Installation Instructions
Power Off: Disconnect all motor/driver power before installation, wiring, or maintenance.
Mounting: Flange-mount horizontally (preferred) or vertically; tighten four bolts evenly to ensure flatness and concentricity.
Coupling: Use a precision coupling; maintain shaft coaxiality to avoid vibration, noise, or bearing damage.
Shaft Handling: Do not hammer the shaft end; avoid excessive radial/axial loads.
Wiring: Use FANUC shielded power/encoder cables; avoid high-voltage parallel runs; maintain minimum bending radius.
Connectors: Secure all connectors; ensure seal integrity to preserve IP54 rating.
Grounding: Earth the motor shell reliably to prevent leakage and electromagnetic interference.
8. Operation Precautions
Do not exceed rated voltage, speed, or torque (risk of overheating, demagnetization, or insulation failure).
No holding brake: Not suitable for vertical or suspended loads (risk of free fall during power loss).
Avoid explosive, corrosive, or conductive dust environments.
Do not disassemble the motor/encoder (voids warranty and damages sealing).
Stop immediately if abnormal noise, vibration, housing temperature >80°C, or servo alarms occur.
Minimize frequent jogging to reduce current surge and thermal stress.
9. Maintenance and Storage Requirements
Cleaning: Regularly remove dust/oil from the housing for effective heat dissipation.
Inspections: Check mounting bolts, coupling tightness, and connector seals periodically.
Bearings: Factory-lubricated (no scheduled oiling); replace if noise/vibration arises.
Seals: Verify shaft/connector seals to maintain IP54 protection.
Storage: Store indoors (5°C–35°C, ≤85% humidity, non-condensing) in original packaging; avoid sunlight, moisture, or heavy loads.
