The FANUC A06B-0075-B103 is a high‑performance AC servo motor from the beta iS 8/3000 series, designed for accurate and responsive feed axes on CNC lathes, machining centers, and automation equipment. It delivers a rated output of roughly 1.2 kW with a stall torque of 7 Nm and a maximum speed of 3000 rpm, giving an excellent balance of torque and speed for small to medium‑size machine axes. The motor operates at a nominal voltage of around 153 V AC and uses a modern beta iA128 encoder for precise position and speed feedback to the FANUC servo drive.
The motor is built with a straight output shaft for easy mechanical integration with couplings, pulleys, or gearboxes, and many listings indicate versions with or without a holding brake, depending on the exact variant supplied. Typical rotor inertia values are approximately 0.00117 kg·m² (without brake) and 0.00124 kg·m² (with brake), making it suitable for applications that need quick acceleration and deceleration without excessive load on the drive. With a maximum torque of about 15 Nm, the motor can provide short‑term overload for rapid moves and cutting operations when commanded by the matched FANUC amplifier.
This beta iS servo motor is commonly used as an OEM part on machines equipped with FANUC controls and is widely available as new, refurbished, or exchange units from industrial automation suppliers, typically supplied tested and backed by warranty. It is designed for standard industrial environments and cabinet‑mounted drives, following the thermal and protection ratings defined for FANUC beta iS series motors in the official data sheet.
