Product Details

FANUC A06B-0086-B203#0100 is βiS B30/2000 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. The #0100 suffix stands for sealed B128iA absolute encoder configuration, which is specially produced for spare replacement of overseas exported machine tools. It adopts 200V three-phase AC power supply, rated speed 2000rpm, delivering the maximum torque output of this low-speed series to handle ultra-heavy roughing tasks. The sealed B128iA absolute encoder preserves axis position data after power failure and removes the homing requirement, and its reinforced sealing structure effectively blocks coolant mist and fine dust in harsh workshop environments. The keyway shaft is made for timing belt and pulley transmission, maintaining stable torque transfer and preventing slippage under extreme heavy cutting load. It is widely installed on horizontal X and Y feed axes of super heavy-duty mold machining centers and large gantry milling machines requiring stable low-speed roughing performance.

This servo motor integrates stator winding, high inertia rotor assembly and sealed B128iA absolute encoder inside red-capped aluminum housing. The B128iA absolute encoder sends high-precision angle feedback signals to servo amplifier to realize closed-loop position, speed and torque control. It is equipped with keyway shaft matched with synchronous pulley and gear set for belt-driven mechanical layout. Without built-in brake, this unit cannot hold shaft position during power outage; external brake assembly is mandatory if used on vertical Z-axis. Two separate connectors are arranged 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 adopts long-life grease lubrication to support continuous low-speed heavy cutting cycles. Its high inertia rotor shows excellent anti-interference capacity during massive material removal, keeping consistent and smooth feed movement for large mold roughing and finishing. Users can adjust servo gain and soft limit parameters on CNC system to match ultra-heavy low-speed feed and the elastic property of belt transmission.

It serves as a direct replacement spare part for original #0100 coded keyway shaft βiS B30/2000 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 ultra-heavy-load low-speed feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and positioning deviation. It is widely deployed in export heavy gantry machining centers, super large mold processing equipment and other belt-driven CNC feed axis applications.
