Fanuc AC Servo Motor Alpha iS 22/4000-B, Straight Shaft, 90VDC Brake, aiAR128

The Fanuc A06B-2265-B705 AC Servomotor represents an absolutely critical electromechanical drive module meticulously engineered to provide massive rotational power for the most demanding primary axes of high-capacity Fanuc industrial robotic systems and heavy-duty machinery. This specific Alpha iS 22/4000-B variant is structurally optimized with a robust straight shaft, ensuring a completely slip-free, ultra-rigid mechanical coupling to heavy planetary gearboxes or direct-drive linkages, completely eliminating mechanical play and catastrophic backlash. Furthermore, it is equipped with a highly dependable internal 90VDC holding brake, which is absolutely essential for safely locking massive gravitational payloads in strict position during unexpected power interruptions or emergency stops. Delivering exceptional torsional rigidity and blistering multi-axis acceleration capabilities up to 4000 RPM, this heavy-duty servo motor guarantees that massive payloads are maneuvered with completely vibration-free continuous-path accuracy. The integration of the advanced aiAR128 absolute encoder flawlessly guarantees unparalleled spatial orientation tracking over millions of relentless continuous-duty operational cycles, pushing the boundaries of kinematic interpolation.
