Yaskawa SGMSH-20DCA6F-OY Sigma II Servo Motor

Description:

The Yaskawa SGMSH-20DCA6F-OY AC Servo Motor is part of the Sigma-II SGMSH series, designed for high-speed, high-precision motion control in industrial automation systems. This model is a 2.0 kW class servo motor typically operating on 400V and engineered for applications requiring fast response, high torque density, and compact size. The SGMSH series uses a segmented stator design to reduce size while maintaining strong torque-to-inertia performance, making it well-suited for high-cycle-rate applications.

Applications:

The Yaskawa SGMSH-20DCA6F-OY AC Servo Motor is used in industrial environments requiring high-speed and high-accuracy motion control. It is commonly deployed in CNC machining centers, robotics, packaging systems, and automated production lines where rapid acceleration, precise positioning, and continuous-duty performance are critical. It is frequently found in legacy Yaskawa Sigma-II systems still in operation.
