Fanuc AC Servo Motor Alpha iS 30/4000-B, Straight Shaft, Key, DC90V Brake

The Fanuc A06B-2268-B805 AC Servomotor represents an absolutely critical electromechanical drive module meticulously engineered to provide massive rotational power for the most demanding primary axes of extreme-capacity Fanuc industrial robotic systems and heavy-duty machinery. This specific Alpha iS 30/4000-B variant is structurally optimized with a robust straight shaft and a precision keyway, ensuring a completely slip-free, ultra-rigid mechanical coupling to heavy planetary gearboxes or direct-drive linkages, completely eliminating mechanical play and catastrophic backlash under colossal stresses. Furthermore, it is equipped with a highly dependable internal DC90V holding brake, which is absolutely essential for safely locking massive 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 despite its size, this heavy-duty servo motor guarantees that massive 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 cycles.
