Abstract

A spindle motor is disclosed, wherein a bearing housing is coupled to a base by press-fit, adhesion or welding to make an assembly process simple and make the manufacturing cost reduced. The bearing housing is formed with a metal sheet to further save the manufacturing cost. A lower end of a support portion of the base coupled with the bearing housing is extended to a lower end of the bearing housing to broaden a coupled area between the base and the bearing housing. Therefore, a coupled strength between the base and the bearing housing can be improved to enhance a perpendicularity of the bearing housing to the base.
