Abstract
Disclosed are a spindle motor and a method of manufacturing the same. A base plate is integrated with a bearing housing using an insert molding or insert injection method at the same time when the bearing housing is made of resin, thereby being capable of securing the verticality of a bearing and a pivot assembled with the bearing housing and the base plate, reducing the manufacturing cost, and improving the efficiency of a manufacturing process. The motor includes a rotor, a pivot configured to have one end connected to the rotor, a bearing configured to rotatably support the outer circumferential face of the pivot, and a bearing housing made of resin and configured to comprise a first concave groove for receiving the bearing and a second concave groove for supporting the other end of the pivot.
