Yaskawa AC Servo Motor 4.4kW SIGMA II L/U-Axis, UP130/UP165

The Yaskawa 142142-2 AC Servomotor is an extraordinarily robust, industrial-grade electrical power unit from the highly proven SIGMA II product line, featuring a massive 4.4-kilowatt power output rating. This exceptionally dynamic, heavy-duty motor is meticulously engineered to govern the most heavily stressed structural joints—specifically the L-axis and U-axis —of the high-capacity Yaskawa UP130 and UP165 industrial robotic manipulators. Its fundamental operational function is to seamlessly and instantaneously convert precise electrical input commands into the immense, highly localized rotational torque strictly required to safely elevate and articulate the massive primary arm structure under extreme payloads of up to 165 kilograms. The deployment of this high-performance servomotor is absolutely vital in demanding automated handling scenarios where incredibly smooth kinetic interpolation, massive lifting capabilities, and completely vibration-free motion are absolute requirements. Featuring an integrated high-resolution absolute encoder, this heavy-duty servo ensures flawless closed-loop trajectory control.
