N2 - In this paper, the effects of driving current and voice coil motor's (VCM) structure parameters (e.g. magnetizer height, width of working air gap and damping hole angle) on the static electromagnetic characteristics are numerically investigated. The results show that the driving current has remarkable effects on the electromagnetic force before magnetic saturation; the oversize current applied to the coil would weaken the electromagnetic conversation because of the energy losses. Besides, the permanent magnets' structure were researched, in order to achieve the stronger electromagnetic force, the magnetizer was embedded in the middle of two permanent magnets, and the static electromagnetic characteristics were investigated. Furthermore, damping holes have significant influence on magnetic flux, the tendency of magnetic saturation will be enhanced with the further increase of damping hole. Among other parameters studied, air gap is the most important parameter affecting electromagnetic force owing to the variation of magnetic induction intensity.
