Cylindrical Voice Coil Motor

  • 格物光学7-圆筒式音圈电机-1.png




    The Gewu optical voice coil motor is a linear motor based on the Lorentz principle, which has the characteristics of simple structure, small size, high acceleration, and fast response. It is widely used in ultra precision positioning systems, semiconductor manufacturing and assembly, high-end CNC machine tools, and optical electron microscopes. At the same time, it is also frequently used in high excitation motion systems such as medical, vibration platforms, and active vibration reduction systems.
