Yaskawa SGMGH-44A2A-YR15 AC Servo Motor 4400W Encoder UTSAE-B17BBF

Description:

The Yaskawa SGMGH-44A2A-YR15 is a Sigma-II AC servo motor used in high-power industrial motion control systems for precise speed and torque regulation, commonly installed in Motoman robotic axes (L/U axis) and heavy-duty CNC automation equipment requiring 4.4 kW performance, and purchased by maintenance teams, OEMs, and integrators for replacement of failed motors, system rebuilds, and retrofit of legacy high-load automation systems.

Applications:

The Yaskawa SGMGH-44A2A-YR15 servo motor is used in industrial automation environments where high torque and stable low-speed performance are required. It is commonly deployed in robotic welding systems, heavy material handling robots, large CNC machining centers, and automated production lines where synchronized multi-axis motion and precise control are critical. This motor is specifically used in Motoman UP-series robots for L/U axis movement.
