Abstract

This paper presents spindle motor with fluid dynamic hearing(FDB) for hard disk drives. Thrust hearing of FDB requires appropriate pressure to operate in smooth rotations. In this study, the thrust forte between rotor and thrust yoke is analyzed using 3D finite clement method and experimental results are compared with the simulated one.
