SGMSH Sigma II
1.0kW to 5.0kW, Rated Speed 3,000 RPM
The SGMSH Sigma II servo motor is a legacy product and no longer promoted in the Americas. The SGMSH servo motor series had a high torque-to-inertia ratio and incorporated the segmented stator design, which dramatically reduced overall size. These servo motors were well suited for high-cycle-rate applications.
