Abstract
In the article the problem of formulation of mathematical models of voice coil motors (VCM), used in hard disk drive head positioning system is presented. In first step finite element models of VCM motors were implemented in Comsol/Matlab programs according to spatial space distribution of magnetic field in air-gap determination. In second step circuit model of VCM motors were formulated in which the calculated space distributions of magnetic field were used, Finally the prepared mathematical models were verified by comparison between measured and simulated steady state and dynamic characteristic.
