Yaskawa SGMPH-04A2A-YR22 Servo Motor

The Yaskawa SGMPH-04A2A-YR22 AC Servo Motor is a 400 W brushless servo motor in the Sigma-II series, engineered for precise speed and position control in medium-duty industrial automation. It runs on 200 VAC three-phase power, delivers up to 3000 RPM and 1.27 Nm of rated torque, with a typical current of about 2–3 A, making it suitable for CNC machines, Motoman robotic axes, packaging lines, and automated production cells, and it is commonly used for replacement and maintenance in legacy Yaskawa systems. With a flange-mount design and compact profile, the SGMPH-04A2A-YR22 belongs to a medium-inertia family known for strong dynamic performance in continuous-duty applications, and its encoder configuration can be incremental or absolute depending on options. As a legacy Sigma-II model, common replacements include the SGMAV-04ADA61 and SGMJV-04ADA21.
