  • Spindle motor, disk drive apparatus, and method of manufacturing spindle motor
    Patent number: 9450457
    Abstract: In a method of manufacturing a spindle motor, a sheet preferably made of a thermoplastic resin is closely adhered to an upper surface of a base portion of a spindle motor such that the sheet covers a base hole of the base portion. Next, heat is applied to a region of the sheet which coincides with the base hole to define a sheet hole continuous with the base hole. Thereafter, a coil is arranged over the base portion, and a conducting wire defining the coil is extended through the sheet hole and the base hole to be drawn downwardly out of the base portion. The sheet hole is thus defined after the sheet is closely adhered to the base portion. In addition, the sheet hole is defined by melting the resin through application of the heat. It is therefore easy to arrange the sheet and define the sheet hole.
