Product Details

FANUC A06B-0032-B075#7008 is the βi-B2/3000 AC servo motor with brake, belonging to FANUC Beta basic servo series, widely matched with FANUC βi servo amplifiers for small CNC milling machines, lathes and automation feed axes. The #7008 variant stands for built-in electromagnetic brake configuration, different from the non-brake #7000 version, which can lock the shaft position when servo power is cut off to prevent sliding of vertical axes. It adopts 200V three-phase AC drive design, rated power 0.5kW, rated speed 3000rpm, and is equipped with built-in A32B absolute encoder, supporting absolute position memory without zero return after power off.

This servo motor integrates stator winding, rotor, high-resolution absolute encoder and holding brake inside one compact aluminum housing. The A32B absolute encoder can feed back precise angular position data to the servo amplifier, achieving high-precision positioning for linear and rotary axes. The internal brake is spring-actuated and power-release type; it engages immediately once control power is lost, which is essential for Z-axis of vertical machining equipment and lifting axes of automation devices. The motor shaft is standard straight shaft, and the rear end is fitted with two separate locking connectors: one for encoder signal cable and one for three-phase power cable, with clear pin definition for quick wiring. It supports closed-loop position, speed and torque control modes, and can follow fast command pulses from FANUC 0i-MF, 0i-TD and other mainstream CNC systems.

The motor housing has good heat dissipation structure and IP65 front shaft sealing, resisting coolant splashes, cutting oil mist and fine metal dust in metal cutting workshops. The internal bearing assembly is pre-lubricated for long continuous operation, and the brake friction plate is optimized for static holding rather than dynamic braking. Compared with Alpha high-performance motors, this Beta series focuses on cost-effective stable operation for general machining axes, and it is the standard configuration for many entry-level and mid-size FANUC machine tools. Users can set servo gain, soft limit and brake delay logic via CNC servo parameters to match vertical axis gravity balance and motion requirements.

It is a direct replacement spare part for original βi B2/3000 servo motors suffering from bearing noise, encoder damage, brake failure, shaft runout and winding burnout. Every unit will pass winding insulation test, encoder position reading test, brake holding force verification and servo drive matching test before shipment, ensuring stable speed regulation and reliable shaft locking function. Replacing this servo motor can quickly restore the feed axis motion of the CNC machine, avoid machining shutdown caused by axis positioning failure or vertical axis dropping. It is widely deployed in CNC lathes, small vertical machining centers, automatic tapping machines and other general FANUC machine tool feed axes.
