Abstract
The invention relates to a spindle motor having a fluid dynamic bearing system comprising axial and radial bearings that contains a rotor component () which encloses a stationary shaft (), which in turn is connected at both its ends to axially aligned bearing parts () that are fashioned such that they form capillary sealing gaps (), a recirculation channel () filled with bearing fluid that connects the remote regions of the bearing to each other, and an electromagnetic drive system () for driving the rotor component.
