AC servo motor that directly generates linear motion without requiring mechanical conversion mechanisms such as ball screws or belts, achieving direct linear drive through electromagnetic force. Used in feed axes of NC machine tools, positioning mechanisms of automatic assembly equipment, wafer transport systems in semiconductor manufacturing equipment, and precision stages of inspection devices. Features high-precision position control and high-speed response as a direct-drive actuator with excellent maintainability, serving as a drive system alternative to conventional rotary motor plus ball screw mechanisms. Composed of mover (forcer) and stator, enabling position feedback control through linear encoders.
