Comprehensive category for linear motors that generate linear motion through the interaction of magnetic fields and electric current. Unlike rotary motors, they provide direct linear drive systems with high-precision positioning without requiring ball screws or belt drive mechanisms. Used in NC machine tool feed axes, semiconductor manufacturing equipment wafer transport, automated assembly line linear conveyance, and high-speed scanning in inspection equipment. Handles various types including linear servo motors, linear stepping motors, magnetic levitation linear motors, and planar motors, including encoder-integrated and direct drive specifications. Clearly distinguished from conventional rotary motor plus conversion mechanisms, characterized by high responsiveness and high precision through linear motion-dedicated design.
