Product Details

FANUC A06B-0127 is αi A6/2000 AC servo motor with tapered shaft, belonging to FANUC Alpha i servo series, compatible with αi servo amplifiers and FANUC 0i-MF, 0i-MF Plus CNC systems. It adopts 200V three-phase AC power supply, rated power 1.0kW, rated speed 2000rpm, stall torque 6.0Nm. This medium-speed high-torque alpha servo motor is designed for heavy load cutting and stable feed movement for vertical machining centers and medium gantry machines. It supports multiple encoder options including absolute and incremental serial encoder versions to satisfy different CNC configuration demands. The tapered shaft is designed for direct coupling connection with ball screw, delivering rigid torque transmission and minimizing backlash during heavy milling and boring cycles. It is widely used on X/Y/Z main feed axes of medium vertical machining centers and mold processing CNC machines.

This servo motor integrates stator winding, medium inertia rotor assembly and serial 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 adopts tapered shaft for rigid coupling layout. The base model does not include built-in holding brake; brake variant is selected separately for vertical axis installation. 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 stable medium-speed operation. Its medium rotor inertia maintains excellent anti-vibration performance during heavy cutting, suitable for mold milling and high-precision boring tasks. Users can adjust servo gain and soft limit parameters on CNC system to match heavy-load medium-speed feed and rigid coupling transmission characteristics.

It serves as a direct replacement spare part for original αi A6/2000 tapered shaft 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 heavy-load stable feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and positioning deviation. It is widely deployed in vertical machining centers, mold CNC milling equipment and other rigid-coupling CNC feed axis applications.
