Fanuc AC Servo Motor Beta iS 2/4000-B (Straight Shaft, Key, DC90V Brake)

The Fanuc A06B-2061-B805 AC Servomotor represents a critical electromechanical drive module meticulously engineered to provide rapid rotational power for the dynamic axes of precision Fanuc industrial robotic systems and specialized machinery. This specific Beta iS 2/4000-B variant is structurally optimized with a robust straight shaft and a precision keyway, ensuring a completely slip-free, ultra-rigid mechanical coupling to planetary gearboxes or direct-drive linkages, completely eliminating mechanical play and catastrophic backlash. Furthermore, it is equipped with a highly dependable internal DC90V holding brake, which is absolutely essential for safely locking gravitational payloads in position during unexpected power interruptions, thereby completely preventing dangerous tooling collisions and structural free-fall. Delivering exceptional torsional rigidity and blistering multi-axis acceleration capabilities, this precision servo motor guarantees that payloads are maneuvered with incredibly smooth, completely vibration-free continuous-path accuracy. Its integrated high-resolution absolute encoder flawlessly guarantees total spatial orientation tracking over millions of relentless continuous-duty operational cycles, maintaining absolute zero-backlash kinetic interpolation.
