SPINDLE MOTOR

摘要

PURPOSE: The spindle motor improves the driving characteristic by getting the protecting of the deformation of the generation of the stable dynamic and bearing part in the rotation process. CONSTITUTION: A herb(150) is used in order to load the magnetic disc or the optical disc. The rotary shaft(140) supports Hub to shaft. The rotary shaft is composed of the rotatable body and bearing part forming journal fluid dynamic bearing. The sleeve(120) has the hollow cylindrical shape phase in order to pivotally support the rotary shaft. The plate(110) supports sleeve.
