SPINDLE MOTOR FOR PREVENTING WEAKENING OF COMBINATION FORCE BETWEEN A BURRING UNIT AND A ROTATION AXIS OF A YOKE BY FORMING A REINFORCEMENT MEMBER ON A LOWER SIDE OF THE YOKE

摘要

PURPOSE: A spindle motor is provided to arrange a thrust plate on an upper side of a clamping unit and to arrange an adhesive in a space between the thrust plate and a rotation axis, thereby strengthening combination force of the clamping unit, the rotation axis, and a burring unit.;CONSTITUTION: A stator is fixed to outer periphery of a bearing housing. A rotation axis(500) is connected to a bearing to be rotated. A rotator includes a yoke and a magnet. A clamping unit(700) is combined with a burring unit(613) of the yoke. A reinforcement member(800) is pressed in the rotation axis and is touched to a lower side of the yoke.;COPYRIGHT KIPO 2013
