Spindle motor with casing for hard disk drive, has separate, pot-shaped casing closed on one side with stator fitted to outer periphery and outer rings of roller bearing fitted to inner periphery

摘要

The motor has a stator (5) fixed with respect to a base plate (10), a rotor (1) whose shaft is rotatably mounted relative to the stator using roller bearings (2,6) and a casing (11) in the form of a separate, pot-shaped part closed on one side with the stator fitted to its outer periphery and the outer rings (3,7) of the roller bearing fitted to its inner periphery.
