Yaskawa Electric Corporation SGMPH-04AAA4C AC Servo Motor

The Yaskawa SGMPH-04AAA4C AC Servo Motor is a 400 W brushless servo from the Sigma-II series designed for precise speed and position control in industrial automation. It operates on 200 VAC three-phase power, delivering a typical 3000 RPM with about 1.27 Nm of torque and uses a ~13-bit incremental encoder for reliable feedback. Its compact, medium-inertia frame with flange mounting supports continuous-duty operation and is commonly deployed in CNC machines, robotics (Motoman), packaging equipment, and automated production lines as a direct replacement or maintenance component for legacy Yaskawa servo systems; common replacements include SGMPH-04AAA41, SGMAH-04AAA41, and SGMJV-04AAA6C.
