Product Details

FANUC A06B-0116-B175#0008 is βiS B2/4000 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-equipped variant of A06B-0116-B075#0008. It adopts 200V three-phase AC power supply, rated power 0.75kW, rated speed 4000rpm, stall torque 2.4Nm. The #0008 suffix stands for standard serial encoder configuration for overseas machine tool replacement projects. The integrated spring-loaded electromagnetic brake engages automatically on power loss, firmly locking the shaft and preventing vertical axis sliding on medium-sized vertical machining centers and tapping machines. The high-resolution serial encoder retains position data after power outage and eliminates homing steps, delivering stable closed-loop feedback during continuous milling cycles. The keyway shaft matches synchronous pulley assembly for belt transmission, offering reliable torque transfer for medium-load milling and positioning tasks. It is widely installed on Z axes and auxiliary rotary axes of medium CNC milling equipment and tapping centers.

This servo motor integrates stator winding, medium 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 designed for static shaft holding instead of dynamic braking during cutting operation. 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 medium-speed cyclic operation. Its moderate rotor inertia balances acceleration responsiveness and cutting anti-interference capacity, suitable for frequent reciprocating feed and light-medium milling processes. Users can adjust servo gain, soft limit and brake delay parameters on CNC system to match vertical axis gravity balance and medium-load medium-speed belt transmission characteristics.

It serves as a direct replacement spare part for original #0008 coded keyway shaft βiS B2/4000 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 medium-speed vertical feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and vertical axis sliding. It is widely deployed in vertical tapping centers, medium CNC milling machines and other belt-driven vertical feed axis applications.
