FANUC AC Servo Motor Model: A06B-0147-B175#7076 Detailed English Specification Manual No Pictures and No Tables 1. Product Overview This is a high-performance medium-inertia AC servo motor from the FANUC Alpha i A22 series, rated at 2000 rpm. It features a straight shaft with keyway, a built-in power-off holding brake, and a high-resolution Alpha A64 absolute encoder. The #7076 suffix denotes an enhanced sealed structure (IP67), making it suitable for CNC machine tools, metalworking equipment, and automation systems in harsh environments with oil mist, dust, and coolant splash. Ideal for both horizontal and vertical axis installation, it delivers high positioning accuracy, stable operation, and long service life. 2. Part Number Definition A06B: FANUC servo motor series prefix. 0147: A22 frame size, medium-inertia rotor, 2000 rpm rated speed. B175: Straight shaft with keyway, with holding brake, integrated Alpha A64 absolute encoder. #7076: Factory enhanced sealing specification (IP67), upgraded shaft seals and environmental protection for harsh conditions. 3. Electrical Performance Parameters Rated output power: 3.8 kW. Rated speed: 2000 rpm. Rated voltage: 3-phase 157 V AC. Rated frequency: 133 Hz. Continuous rated torque: 22 Nm. Rotor inertia: Medium inertia. Encoder: Alpha A64 serial absolute encoder, 65536 ppr resolution. Holding brake: Built-in power-off brake (engages on power loss). Insulation class: Class F (max 155°C). Cooling method: Natural air cooling (surface heat dissipation). Stall torque: 22 Nm (locked rotor). Rated current: 15 A; Stall current: 19 A. 4. Mechanical Structure Features Mounting: Standard square flange (A22 frame dimensions). Shaft: Straight with standard keyway; #7076 uses reinforced lip seals for IP67 protection. Housing: Compact cast aluminum, high rigidity, low noise. Bearings: High-precision assembly for smooth operation. Net weight: Approx. 29.5 kg. 5. Environmental Protection Grade and Working Conditions Protection class: IP67 (#7076) (dust-tight, protected against temporary immersion). Operating temperature: 0°C to 55°C. Storage temperature: -20°C to 70°C. Humidity: 10%–90% (non-condensing). Altitude: ≤1000 m (no power derating). Vibration resistance: Up to 5G (machine tool compatible). 6. Main Product Features Medium-inertia rotor: Balances dynamic response and stability for frequent start/stop, reversing, and variable loads. Alpha A64 absolute encoder: High precision, no external battery needed, supports power-on homing-free operation. Built-in holding brake: Safe for vertical/suspended loads (prevents free fall on power loss). IP67 enhanced sealing: Withstands oil mist, dust, and coolant splash; ideal for harsh workshops. Natural cooling: Fanless design reduces maintenance and failure risk. High rigidity construction: Low noise/vibration at high speeds. Amplifier compatibility: Fully compatible with FANUC Alpha i-B series servo amplifiers. 7. Installation Instructions Power Off: Disconnect all motor/driver power before installation, wiring, or maintenance. Mounting: Flange-mount horizontally/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 bending radius. Connectors: Secure all connectors; ensure seal integrity to preserve IP67 rating. Grounding: Earth the motor shell reliably to prevent leakage and interference. 8. Operation Precautions Do not exceed rated voltage, speed, or torque (risk of overheating, demagnetization, or insulation failure). The built-in brake is for holding only; do not use for dynamic stopping. Test brake performance regularly for vertical axes. Avoid explosive, corrosive, or conductive dust environments. Do not disassemble the motor/encoder (voids warranty and damages sealing). Stop immediately if abnormal noise, vibration, >80°C housing temperature, 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 IP67 protection. Storage: Store indoors (5°C–35°C, ≤85% humidity, non-condensing) in original packaging; avoid sunlight, moisture, or heavy loads. 10.
