BRUSHLESS MOTOR, DISK DRIVE APPARATUS, AND METHOD OF MANUFACTURING THE BRUSHLESS MOTOR

摘要

A stationary unit of a brushless motor includes a flat armature and a base member arranged to support the armature. The armature includes a power supply portion to which a lead wire is connected. The base member includes a wall portion and a window portion. The wall portion is radially opposed to an outer edge portion of the armature. The window portion is positioned below the power supply portion to axially extend through the base member. An adhesive agent exists between the wall portion and the outer edge portion of the armature. Accordingly, the base member and the armature are strongly fixed to each other. Further, a sealing material is interposed between a whole periphery of an edge of the window portion and the armature, so that the window portion is sealed. (FIG. 1)
