Product Details

FANUC A06B-0128-B675#7008 is αi A6/3000 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 1.4kW, rated speed 3000rpm, stall torque 6.0Nm. The #7008 suffix represents standard A64 multi-turn absolute encoder variant for overseas machine retrofit and spare replacement. The integrated spring-type electromagnetic brake engages automatically once power supply fails to lock the shaft firmly and prevent vertical axis drop on vertical machining centers and medium mold milling machines. The A64 absolute serial encoder retains coordinate data after power loss and eliminates homing routine, delivering stable high-precision feedback during continuous heavy cutting cycles. The straight keyway shaft matches timing belt pulley assembly, maintaining reliable torque transmission and anti-slip performance for medium and heavy load milling and drilling processes. It is widely fitted on Z axes and rotary fourth axes of vertical machining centers that need static position holding.

This servo motor integrates stator winding, medium 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 medium-high-speed operation. Its medium rotor inertia balances acceleration responsiveness and vibration suppression during heavy cutting, suitable for mold precision milling and repeated positioning tasks. Users can adjust servo gain, soft limit and brake delay parameters on CNC system to match vertical axis gravity balance and medium-heavy-load belt transmission characteristics.

It serves as a direct replacement spare part for original #7008 coded αi A6/3000 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 medium-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.
