ABSTRACT:
The invention relates to a spindle motor having a fluid dynamic bearing system that contains a rotor component taking the form of an integrated hub/bearing bush arrangement which encloses a straight, stationary shaft, which in turn is connected at both its ends to axially aligned bearing components, formed in such a way that they seal the fluid dynamic bearing system formed between the shaft and the rotor component and open at both ends. The open ends of the bearing gap are sealed by capillary seals or pumping seals or a combination of capillary and pumping seal.
