Abstract :
Due to the coupled effects between axial magnetic force and unbalanced magnetic force on the proposal geometry construction in spindle motor, the tracking status will be seriously affected during the data storage processing in media system. There are some types of axial geometric configurations are analyzed and discussed the unbalanced magnetic forces for high precious and high positioning spindle motor by 3D finite element method, which are including of permanent magnet rotor and slotted stator with coils in this paper, the variation of axial geometric configurations are investigated by experimental design parameter to calculate the electromagnetic forces, and to measure the vibrating magnitudes, to evaluate the coupling dynamic characteristics in spindle motor
