Product Details

FANUC A06B-0141-B175#7008 is αi A12/2000 AC servo motor with straight keyway shaft and built-in 24V holding brake, 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 1.8kW, rated speed 2000rpm, stall torque 12Nm. The #7008 suffix represents standard A64 multi-turn absolute encoder variant for overseas machine retrofit and spare replacement projects. The integrated spring-loaded electromagnetic brake automatically locks the shaft once power supply fails, effectively preventing vertical axis dropping and holding position steadily for vertical machining centers and heavy-duty mold milling machines. The A64 absolute serial encoder retains coordinate data after power loss and skips homing steps, providing stable high-precision serial feedback even under continuous low-speed heavy cutting conditions. The straight keyway shaft matches timing belt pulley assembly, delivering stable anti-slip torque transmission for heavy-load milling, boring and tapping processes. It is commonly installed on Z axes and rotary fourth axes of vertical machining centers that require static axis holding.

This servo motor integrates stator winding, high inertia rotor assembly, A64 absolute serial encoder and spring static holding brake inside aluminum housing. The encoder transmits high-precision angle feedback signals to servo amplifier to realize closed-loop position, speed and torque control. It adopts straight keyed shaft for belt transmission layout. 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 low-speed heavy-load operation. Its high rotor inertia brings excellent vibration suppression during hard material heavy cutting, suitable for high-precision mold processing and repeated positioning. Users can adjust servo gain, soft limit and brake delay parameters on CNC system to match vertical axis gravity balance and heavy-load low-speed belt transmission characteristics.

It serves as a direct replacement spare part for original #7008 coded αi A12/2000 keyed shaft 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 heavy-load stable vertical feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and vertical axis sliding. It is widely deployed in vertical machining centers, mold CNC milling equipment and other belt-driven CNC vertical feed axis applications.
