Abstract

A stator of a motor has a structure including a plate portion coupled to a support structure for fixing a stator core and protrusions inserted into a bobbin. The support structure for fixing the stator core has a structure into which the protrusions of the stator core are inserted and extend into and on which the plate portion of the stator core is inserted and seated. The plate portion of the stator core is joined to the support structure while being coplanar with the support structure. Accordingly, the distance of a gap between the stator core of the stator and a permanent magnet of a rotor is minimized, thereby improving the performance of the motor.
