摘要：
The invention relates to a spindle motor having a stationary part and a rotating part that are rotatably supported with respect to each other by means of radial and axial bearing systems, the radial bearing system being a fluid bearing and the rotating part being driven by an electromagnetic drive system. The spindle motor is characterized in that the axial bearing system is designed as a magnetic bearing and that it operates against a magnetic preload.
