Yaskawa Electric Corporation SGMPH-15D4AJ36B Servo Motor

The Yaskawa SGMPH-15D4AJ36B is a brushless AC servo motor in the Sigma-II family, delivering approximately 1.5 kW of continuous power for high-precision speed and position control in industrial automation. Designed for medium-to-high power motion, it's commonly used in CNC machining centers, robotic axes, material handling systems, and packaging lines where accurate positioning and torque consistency under continuous duty are critical. Key specifications include 400 VAC operation (D-series denotes a higher voltage class), a rated current of roughly 3–5 A, a rated torque of about 4.7 Nm, and a typical speed around 3000 RPM, with a flange-mount form factor and an approximate weight of 20 lb; the encoder can be incremental or absolute depending on configuration. This legacy/discontinued platform is often kept in service as a replacement or maintenance option, with the SGMGH-13A2A-YR23 listed as a common replacement.
