Maglev Voice Coil Motor

  • 格物光学6-磁浮式音圈电机-1.png




    The Gewu Optical Maglev Voice Coil Motor adopts a combination design method, integrating passive maglev technology into the structure of the voice coil motor. The structure is simple, small in size, and vertically capable of gravity compensation, achieving vertical high load motion. The gravity compensation force can be customized according to the customer's load situation, and the compensation force range is relatively wide. It can be widely applied in the medical field and semiconductor equipment.
