Product Details
FANUC A06B-0115-B175#0008 is βiS B1/6000 AC servo motor with keyway shaft and built-in 24V holding brake, belonging to FANUC Beta iS servo series, compatible with βiS servo amplifiers and FANUC 0i-MF, 0i-MF Plus CNC systems. It is the brake version of A06B-0115-B075#0008. It adopts 200V three-phase AC power supply, rated power 0.4kW, rated speed 6000rpm, designed for ultra-high-speed operation and fast dynamic response for light and medium load positioning. The #0008 suffix stands for standard encoder configuration for aftermarket replacement. The integrated spring-loaded electromagnetic brake locks the shaft immediately once power cuts off, effectively preventing vertical axis drop on small high-speed tapping centers and engraving machines. The high-resolution serial encoder retains axis position data after power failure and skips homing operation, delivering stable position feedback during continuous high-speed cycles. The keyway shaft matches timing belt and pulley assembly, maintaining steady torque transfer and preventing slippage under medium cutting loads. It is widely installed on vertical Z axes and auxiliary rotary axes of high-speed engraving equipment and compact tapping machines.
This servo motor integrates stator winding, ultra-low inertia rotor assembly, high-resolution serial encoder and spring static holding brake 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. The built-in brake is power-release type, only for static shaft holding instead of dynamic braking during high-speed running. 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 rapid acceleration and deceleration, perfectly suited for high-frequency short-stroke reciprocating movement and fast positioning. Users can adjust servo gain, soft limit and brake delay parameters on CNC system to match vertical axis gravity balance and ultra-high-speed medium-load belt transmission characteristics.
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, brake slip, shaft wear and winding burnout. Every unit will pass winding insulation test, encoder position reading test, brake holding force verification and servo amplifier matching test before shipment, ensuring stable torque output and reliable static locking performance. Replacing this servo motor can restore medium-load ultra-high-speed vertical feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and vertical axis sliding. It is widely deployed in high-speed tapping machines, compact engraving equipment and other belt-driven CNC feed axis applications.
