Product Details

FANUC A06B-0113-B175#7008 is βiS B0.5/3000 AC servo motor with keyway shaft and built-in 24V 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 0.2kW, rated speed 3000rpm, stall torque 0.65Nm. The #7008 suffix stands for A32B absolute encoder variant, which is widely selected for overseas machine tool after-sales replacement. The integrated spring-loaded electromagnetic brake locks the shaft once power is cut off, effectively preventing vertical axis drop for small vertical sliding axes. It is equipped with high-resolution absolute encoder that retains position information after power outage and removes homing steps. The keyway shaft matches synchronous pulley for belt transmission, delivering stable torque transfer for light and medium load movements. It is commonly installed on Z-axis, fourth rotary axis and auxiliary sliding axes of small engraving machines and compact CNC machining centers.

This servo motor integrates stator winding, low inertia rotor assembly, A32B absolute encoder and spring static holding brake inside red-capped aluminum housing. The encoder sends high-precision angle feedback signals to servo amplifier for closed-loop position, speed and torque control. The built-in brake is power-release type, only designed for static shaft holding instead of dynamic braking during high-speed operation. Two separate connectors are reserved at the rear for power cable and encoder cable, complying with 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 high-speed light-load cycles. Its low rotor inertia realizes fast acceleration and deceleration response, suitable for frequent short-stroke positioning tasks. Users can adjust servo gain, soft limit and brake delay parameters on CNC system to fit vertical axis gravity balance and light-load high-speed belt transmission characteristics.

It serves as a direct replacement spare part for original #7008 coded keyway shaft βiS B0.5/3000 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 light-load high-speed vertical feed axis motion rapidly, avoid machine shutdown caused by cutting interruption and vertical axis sliding. It is widely deployed in small engraving equipment, compact CNC machining centers and other belt-driven auxiliary feed axis applications.
