SPINDLE MOTOR AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A spindle motor, and a manufacturing method thereof are provided to minimize the gap between adjacent combining parts by coiling a protrusion part and fixing·combining a combining part to the protrusion part, thereby improving the motor performance and reducing a coking torque. CONSTITUTION: A spindle motor comprises an armature. The armature comprises a core and a coil which is coiled on the core. The core (110) comprises a protrusion part (112) on which the coil is coiled, and a fixing part (113) which is fixed·combined to the end part of the protrusion part.
