Product Details

FANUC A06B-0116-B203#0100 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. It adopts 200V three-phase AC power supply, rated power 0.5kW, rated speed 6000rpm, stall torque 1.2Nm. The #0100 suffix represents B64iA absolute encoder and IP67 high sealing variant, upgraded for harsh workshop environments with coolant splash and mist. The B64iA absolute encoder retains axis coordinate data after power loss and eliminates homing operation, delivering stable high-precision serial feedback during continuous ultra-high-speed operation. The keyway shaft matches timing belt and pulley assembly, maintaining reliable torque transfer for light and medium milling loads. It is widely used on X/Y feed axes and fourth rotary axes of high-speed tapping centers and compact vertical machining centers that require better waterproof and oil-proof performance.

This servo motor integrates stator winding, medium-low inertia rotor assembly and B64iA serial absolute 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 variant cannot lock the shaft during power loss; external brake assembly must be equipped if deployed 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 IP67 protection grade, capable of resisting direct coolant splashing, 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 fast acceleration and deceleration, suitable for frequent 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 #0100 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 CNC milling equipment and other belt-driven CNC feed axis applications.
