摘要:
A spindle motor in one inventive implementation includes a rotor hub (10) for retaining a rotor magnet (70) and a stator (80) which is faced to the radial inner side of the rotor magnet (70) with a gap interposed therebetween. A shield sheet (90) is placed between the upper side of the winding (82) of the stator (80) and the disk mounting portion (13) of the rotor hub (10) and the outer peripheral edge of the shield sheet (90) is placed radially inside of the outer peripheral edge of the core back (83) of the stator (80).
