Design of a Voice Coil Motor Used in the Focusing System of a Digital Video Camera

摘要

This paper raises a valid method to design a voice coil motor (VCM) used in the focusing system of a digital video camera (DYC). A better VCM performance, such as lower battery consumption, higher efficiency, and shorter focusing time, can be achieved by turning the diameter of a winding coil, the thickness of the magnet, and the winding spaces in a VCM.
