Product Details

FANUC A06B-0116-B403#0100 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 adopts 200V three-phase AC power supply, rated power 0.5kW, rated speed 6000rpm. The #0100 suffix stands for B64iA absolute encoder configuration, which is widely selected for overseas machine retrofitting and spare replacement projects. The integrated spring-loaded electromagnetic brake automatically locks the shaft once power supply fails, preventing vertical axis sliding on compact tapping centers and small vertical machining centers. The B64iA absolute encoder retains coordinate data after power outage and removes homing steps, delivering stable high-precision serial feedback even under continuous ultra-high-speed operation. The keyway shaft matches synchronous pulley assembly for belt transmission, maintaining reliable torque transfer for light and medium milling loads. It is commonly installed on Z axes and auxiliary rotary axes of high-speed tapping machines and compact CNC milling equipment that need position holding.

This servo motor integrates stator winding, medium-low inertia rotor assembly, B64iA absolute 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 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 ultra-high-speed cyclic operation. Its moderate-low rotor inertia supports rapid acceleration and deceleration, suitable for frequent short-stroke reciprocating positioning tasks. 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 #0100 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 CNC milling equipment and other belt-driven vertical feed axis applications.
