Overview
The Yaskawa USASEM-30AE2K is a 30-size AC servo motor from Yaskawa’s S Series, designed for high-precision positioning and motion control in industrial automation applications. This compact yet powerful servomotor features a rare-earth magnet design and delivers responsive torque output across a wide speed range. The USASEM-30AE2K integrates with Yaskawa’s Sigma servo drive family and is widely used in CNC machinery, robotic systems, and factory automation environments where repeatability and accuracy are critical.
