Abstract

The present invention provides a spindle motor and a storage disk drive having the same. The spindle motor includes a base part which contains a through hole and expands radially around a central axis, a rotor hub which is positioned on the upper side of the base part, being rotatable around the central axis, a stator which is positioned on the upper side of the base part and contains a coil having a leader line, and a circuit board which is positioned on the lower surface of the base part. The base part contains a plurality of grooves on the lower surface, at least one through holes are arranged in the grooves, the leader line passes through the through holes and reaches the lower surface of the base part and is electrically connected with a welding disc part of the circuit board.

Description

[0001] This application is based on a divisional application of an invention patent application titled "Spindle Motor and Recording Disk Drive Device Having the Spindle Motor" with the filing date of December 31, 2010 and the application number of 201010620121.8. technical field [0002] The present invention relates to a spindle motor and a recording disk drive device having the same. Background technique [0003] In the disk drive motor disclosed in JP 2000-209804 A, the lead wires of the coils are passed through the lead wire holes of the motor bracket to be electrically connected to the flexible circuit board. The lead-out holes are closed by the flexible circuit board. Attach the flexible circuit board to the bottom surface of the motor bracket with an adhesive. [0004] However, as in JP 2000-209804 A, in the case of a structure in which the bottom surface of the motor bracket is soldered, it is necessary to plan the bottom surface of the motor bracket in consideratio...
