The present invention relates to a voice coil module (VCM), and more particularly, to a VCM used for lens fixation and displacement measurement in order to prevent and control power consumption. Accordingly, in the VCM, power is not additionally consumed in order to maintain a specific position of the lens in a state that a focus of the lens is adjusted. Further, the lens is not moved and an optical axis is not distorted when a vibration occurs while an image is captured. Furthermore, the lens can be accurately controlled by measuring the present position of the lens.
