The GYS401DC2-T2A is a 400 W ultra-low inertia AC servo motor from the Fuji Electric FALDIC-W GYS Series, designed for high-speed positioning and frequent acceleration/deceleration applications.
Unlike general-purpose motors that focus mainly on continuous torque output, the GYS series is optimized for dynamic motion performance. Its low inertia rotor enables fast acceleration, rapid stopping and stable positioning during repeated machine cycles.
The integrated 17-bit incremental encoder provides high-resolution feedback for precise servo control, while the compact 400 W design delivers a balance of speed, torque and responsiveness.
The T2A configuration is a standard non-brake version, suitable for horizontal axes and compact automation mechanisms requiring reliable motion performance.
