摘要： Provided is a high-speed rotating spindle motor that achieves a smooth circulation of oil without any congestion regions of oil on an oil path taking place in a bearing housing. The spindle motor includes: a rotor; a rotating shaft whose one end is combined with the rotor; a sleeve bearing whose inner circumference rotatably supports the outer circumferential surface of the rotating shaft, and on the outer circumferential surface of which at least one oil circulation recess is provided along the lengthy direction of the sleeve bearing, and that is made of an oil-containing sintered metal; a bearing housing having a first recess accommodating the sleeve bearing and a second recess that supports the other end of the rotating shaft at a central portion of the first recess, and made of a resin; and a number of protrusions that are protrudingly formed at a gap radially spaced apart from each other around the rotating shaft so that a plurality of guide grooves through which oil passes are formed on the bottom of the first recess, and on which the bottom of the sleeve bearing is mounted.

摘要： Provided is a spindle motor having an electrostatic discharge (ESD) path that can stably discharge electric charges introduced from the outside to a rotating shaft through a base plate, in a structure of forming a bearing housing by using a resin and insert-molding the base plate. The spindle motor includes: a rotor to the central portion of which one end of a rotating shaft is coupled; a bearing that rotatably supports the rotating shaft; a bearing housing that accommodates the bearing in the inside of a groove and that is made of a resin; and a base plate whose inner circumferential portion is buried and combined in the inside of the bearing housing, wherein part of the base plate is in contact with the bearing to thus discharge externally introduced static electricity through the rotating shaft, bearing, and the base plate.
