Abstract:
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.
