发明名称 Spindle motor having a fluid dynamic bearing system
摘要 The invention relates to a spindle motor having a fluid dynamic bearing system, used particularly for driving the storage disks of hard disk drives, having a baseplate, a stationary bearing bush disposed in an opening in the baseplate, a shaft rotatably supported in an axial bore in the bearing bush by means of the fluid dynamic bearing system, a hub connected to the shaft, and an electromagnetic drive system.
