SPINDLE MOTOR

摘要

Embodiments of the invention provide a spindle motor including a stator including a base plate having a through-hole formed therein, a core provided in the base plate, and a flexible printed circuit applying a current to the core. According to at least one embodiment, the spindle motor further includes a rotor including magnet facing the core, wherein the flexible printed circuit includes a land part formed on one surface of the flexible printed circuit to allow a coil which is wound around the core to be soldered and connected thereto, and a coil leading hole formed to be in communication with the through-hole and formed at a position out of the land part to be separated. According to various embodiments, cold soldering defect and disconnection of the coil is prevented.
