Product Details

FANUC A06B-0116-B403 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, rated current 1.8A, designed for ultra-high-speed vertical feed applications. The integrated spring-loaded electromagnetic brake engages automatically once power is cut off, reliably holding vertical sliding axes and preventing axis drop for compact tapping centers and small vertical machining centers. It is equipped with high-resolution serial encoder that retains position data after power failure and eliminates homing routine. The keyway shaft matches synchronous pulley for belt transmission, delivering stable torque transfer for light and medium milling loads. It is widely fitted on Z axes and auxiliary rotary axes of high-speed tapping machines and small CNC milling equipment.

This servo motor integrates stator winding, medium-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 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 movement and fast 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 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.
