FANUC AC Servo Motor A06B-0286-B310 General Description The A06B-0286-B310 is a high-performance AC servo motor from the FANUC αiF series, engineered for 200V-class industrial automation systems. It features a straight shaft with keyway, a built-in high-resolution incremental encoder, and a holding brake. Designed with a compact, lightweight structure and natural cooling, this motor delivers high torque density, smooth low-speed operation, and precise positioning. It is ideal for medium-duty CNC machines, industrial robots, and automation equipment requiring static holding. Main Technical Specifications Model: A06B-0286-B310 (αiF series) Rated Continuous Output Power: 0.75 kW Rated Continuous Torque: 2.4 Nm; Maximum Torque: 8.3 Nm Rated Speed: 3000 rpm; Maximum Speed: 5000 rpm Rated Voltage: Three-phase 200–230 V AC Rated Current: 3.5 A; Peak Current: 10.5 A Encoder: Built-in incremental encoder (1000 ppr) Shaft: Straight shaft (ST) with keyway (KEY) Brake: With 24 V DC holding brake Cooling: Natural convection (self-cooled) Protection Class: IP65 (dust-tight, splash-proof) Insulation Class: F (155 °C) Rotor Inertia: 0.00053 kg·m² Approximate Weight: 4.7 kg Product Features Integrated Holding Brake: Equipped with a 24 V DC brake to maintain load position during power-off, preventing axis drift in vertical or inclined applications. Compact & Lightweight: Space-saving design (4.7 kg) reduces installation footprint and mechanical stress on support structures. High Torque Density: Delivers 2.4 Nm continuous torque at 3000 rpm, optimized for high-speed, medium-load operations. Fast Dynamic Response: Low rotor inertia enables rapid acceleration/deceleration and stable low-speed performance for precision motion control. IP65 Protection: Sealed housing resists dust, coolant, and oil mist, ensuring reliability in harsh industrial environments. High-Reliability Encoder: Built-in incremental encoder provides accurate position/speed feedback for consistent positioning accuracy. Natural Cooling: Self-cooled design eliminates external fans, reducing maintenance needs and operational noise. Wide Compatibility: Matches FANUC αiSV series 200V servo amplifiers and 0i‑D/30i‑B series CNC systems for seamless integration. Application Scope CNC Machine Tools: Medium CNC lathes, milling machines, and vertical machining centers for feed axes requiring holding (e.g., Z-axis). Industrial Robotics: Light-to-medium duty robot arms, SCARA robots, and gantry robots with vertical joints. Automation Equipment: Packaging machinery, material handling systems, and assembly lines needing static position retention. Special Machines: Precision positioning stages, laser cutters, and automated testing equipment with vertical or inclined axes. Installation Instructions Mount the motor on a rigid, flat base to avoid resonance and misalignment. Keep the mounting surface clean, flat, and free of debris or burrs. Align the motor shaft with the load; use a flexible coupling to compensate for minor misalignment. Tighten flange bolts evenly to the specified torque to prevent housing distortion. Reserve sufficient clearance around the motor for ventilation, brake wiring, and maintenance access. Ensure the brake is electrically connected and functional before applying load. Wiring Requirements Perform all wiring with the power disconnected to avoid electric shock. Use FANUC-approved power, encoder, brake, and ground cables. Connect three-phase power lines (U, V, W), protective earth (PE), and 24 V DC brake terminals securely. Route encoder signal cables separately from main power and brake cables to avoid electromagnetic interference (EMI). Ensure all wiring terminals are tightly fastened with good insulation performance. Follow FANUC’s official wiring diagram for proper brake polarity and operation. Working Environment Operating Temperature: 0 °C to +40 °C Storage Temperature: −20 °C to +60 °C (non-condensing) Humidity: ≤80% RH (non-condensing) Altitude: ≤1000 m (derate output above 1000 m) Atmosphere: Free of corrosive gases, explosive dust, or excessive oil mist Maintenance Instructions Regularly cut off the power and clean dust and oil stains from the motor housing and brake assembly. Periodically check mounting bolts, coupling tightness, encoder connectors, and brake wiring for security. Listen for abnormal bearing noise during operation; replace bearings if noise occurs. Test brake operation monthly: verify holding torque and release function under no-load conditions. Use the CNC system’s diagnostic function to check encoder signal quality regularly. Do not disassemble the motor, encoder, or brake privately; this will damage precision components and void the warranty. Safety Precautions Only qualified personnel may install, wire, or maintain the motor and brake system. Disconnect all power (main and brake) before maintenance or wiring; wait for capacitors to fully discharge. Never touch the rotating shaft, live electrical components, or brake parts during motor operation. Ensure reliable grounding to prevent electric shock and reduce EMI. Do not modify the motor’s internal structure, encoder configuration, or brake wiring arbitrarily. The brake is for static holding only; do not use it for dynamic braking or emergency stops.
