  • Abstract
    This paper discusses the beneficial and detrimental effects of unbalanced magnetic forces developed in a fluid bearing spindle motor used for hard disk drives. The analysis made in this paper shows that unbalanced forces can be useful for magnetic preloading and stabilizing the fluid bearing system of a hard disk drive spindle motor
