ABSTRACT:
A spindle motor comprises a stationary shaft, a rotor hub having an annular rotor magnet and rotatably mounted by bearings to the stationary shaft, a stator fixedly mounted to the stationary shaft so as to face the rotor magnet, a flexible printed circuit board connected to leads from the stator, and a reinforcement member composed of an annular plate portion and a tubular portion extending axially from the inner edge of the plate portion and disposed between the stationary shaft and the stator. For assembly, the stator is fitted onto the outer side of the tubular portion and then, the flexible printed circuit board is mounted to the plate portion of the reinforcement member. The tubular portion of the reinforcement member is joined to the outer side of the stationary shaft. Accordingly, the flexible printed circuit board is strengthened effectively and the assembly of the components will be eased.
