摘要： A disk rotating motor is provided with: a stator including a stator core and a bracket for fixing the stator core; a rotor that can be rotated with respect to the stator and includes a shaft; and a bearing that rotatably supports the rotary shaft on the outer diameter side of the rotary shaft. The bracket includes a cylindrical portion extending along the shaft and a folded portion formed by folding the upper end of the cylindrical portion onto the outer diameter side. The bearing is fixed to the inner circumferential surface of the cylindrical portion whereas the stator core is fixed to the outer peripheral surface of the folded portion.

摘要： A disk rotating motor is provided with: a stator including a stator core and a bracket for fixing the stator core; a rotor that can be rotated with respect to the stator and includes a rotary shaft; and a bearing that rotatably supports the rotary shaft on the outer diameter side of the rotary shaft, the bearing being supported by the bracket.The bracket includes a cylindrical portion extending along the rotary shaft, and a folded portion formed by folding the upper end of the cylindrical portion onto the outer diameter side such that at least a coaxial part of the folded portion extends coaxially along an outer surface of the cylindrical portion. The cylindrical portion and the folded portion are sandwiched by the stator core and the bearing in a radial direction.
