Product Details

FANUC A06B-0113-B075#0076 is βiS B0.5/3000 AC servo motor with keyway shaft and no built-in holding brake, belonging to FANUC Beta iS servo series, compatible with βiS servo amplifiers and FANUC 0i-MF, 0i-MF Plus CNC systems. It adopts 200V three-phase AC power supply, rated power 0.2kW, rated speed 3000rpm, stall torque 0.65Nm, equipped with high-resolution serial encoder that retains position data after power failure and skips homing operation. This compact lightweight motor features small frame size and low inertia rotor, delivering fast dynamic response for light-load feed motion. The keyway shaft is designed for timing belt and pulley transmission, keeping stable torque transfer and preventing slippage under light and medium cutting loads. It is widely used for auxiliary axes, fourth rotary axes and small sliding feed axes on compact engraving machines and small CNC machining centers.

This servo motor integrates stator winding, low inertia rotor assembly and high-resolution serial encoder inside red-capped aluminum housing. The encoder transmits high-precision angle feedback to servo amplifier, supporting closed-loop position, speed and torque control. It comes with keyway shaft matched with synchronous pulley for belt-driven mechanical layout. Without built-in brake, this variant cannot lock the shaft during power loss; external brake assembly must be equipped if deployed on vertical Z-axis. Two separate connectors are arranged at the rear for power cable and encoder cable, following FANUC standard pin definition for convenient wiring and maintenance.

The front shaft sealing structure reaches IP65 protection grade, resisting coolant splashes, cutting oil mist and fine metal dust in CNC workshops. The internal bearing set uses long-life grease lubrication to sustain continuous high-speed light-load cycles. Its low rotor inertia ensures quick acceleration and deceleration, ideal for high-speed positioning and frequent short-stroke movement. Users can adjust servo gain and soft limit parameters on CNC system to match light-load high-speed feed and the elastic property of belt transmission.

It serves as a direct replacement spare part for original #0076 coded keyway shaft βiS B0.5/3000 servo motors suffering from bearing abnormal noise, encoder signal loss, shaft wear and winding burnout. Every unit will pass winding insulation test, encoder position reading test and servo amplifier matching test before shipment, ensuring stable torque output and precise positioning performance. Replacing this servo motor can restore light-load high-speed feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and positioning deviation. It is widely deployed in small engraving machines, compact CNC equipment and other belt-driven auxiliary feed axis applications.
