Yaskawa Electric Corporation SGMPH-02A1A-YR31 AC Servo Motor

The Yaskawa Electric Corporation SGMPH-02A1A-YR31 AC Servo Motor is a Sigma-II series brushless servo motor designed for precise speed and position control in industrial automation systems. Rated at 200 W and 3000 RPM, it operates on 200 VAC three-phase power with a rated current of about 2.0 A and a rated torque of 0.637 Nm, and weighs approximately 1.9 kg. Commonly used in Motoman robotic systems, CNC machinery, and automated production equipment, it is well suited for replacement and maintenance in legacy Yaskawa installations, offering fast dynamic response and stable torque for light-to-medium duty applications. Encoders can be incremental or absolute depending on configuration, and this model is part of the legacy Sigma-II platform (discontinued). Common replacements include SGMPH-02A1A-YR32 and SGMJV-02ADA61.
