Product Details

FANUC A06B-0115-B075#0008 is βiS B1/6000 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. The #0008 suffix represents keyed shaft standard encoder version, widely used for original machine matching and aftermarket replacement. It adopts 200V three-phase AC power supply, rated power 0.4kW, rated speed 6000rpm, engineered for ultra-high-speed operation with rapid dynamic response for light and medium load positioning tasks. The high-resolution serial encoder preserves axis position data after power failure and eliminates homing steps, delivering stable position feedback during continuous high-speed running. The keyway shaft is matched with timing belt and pulley assembly, maintaining steady torque transfer and preventing slippage under medium cutting loads. It is commonly fitted on X/Y feed axes and rotary fourth axes of high-speed engraving machines and small high-speed tapping centers.

This servo motor integrates stator winding, ultra-low inertia rotor assembly and high-resolution serial encoder inside red-capped aluminum housing. The encoder transmits high-precision angle feedback signals to servo amplifier to realize closed-loop position, speed and torque control. It comes with keyway shaft for belt-driven mechanical layout. Without built-in brake, this unit cannot lock shaft position during power outage; external brake set is required if installed on vertical Z-axis. Two separate connectors are reserved 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 support continuous high-speed cyclic operation. Its ultra-low rotor inertia supports fast acceleration and deceleration, perfectly suited for high-frequency short-stroke reciprocating movement and rapid positioning. Users can adjust servo gain and soft limit parameters on CNC system to match medium-load ultra-high-speed feed and the elastic property of belt transmission.

It serves as a direct replacement spare part for original #0008 coded keyway shaft βiS B1/6000 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 medium-load ultra-high-speed feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and positioning deviation. It is widely deployed in high-speed tapping machines, compact engraving equipment and other belt-driven CNC feed axis applications.
