Yaskawa Electric Corporation USADED-40YRW11 AC Servo Motor

The Yaskawa USADED-40YRW11 is a 4.0 kW brushless AC servo motor designed for high-torque, precise control in industrial robotics and CNC motion systems. It provides a rated speed of 2000 RPM at 230 VAC with a rated current of 23.2 A and comes in a ~100 mm frame with a 4-bolt flange mount, plus an incremental encoder (~2500 PPR) for accurate positioning and repeatability. This IP65-sealed motor uses natural convection cooling and a spline gear shaft (13-tooth typical), making it suitable for Motoman robot axes, robotic welding, heavy material handling, CNC machining centers, and automated production lines where reliable multi-axis synchronization is critical. A 24 V DC holding brake is available as an option, and the unit is commonly used for replacement or retrofit in high-load automation systems requiring continuous operation.
