Kind Code:
A1
Abstract:
The present invention relates to a stator and a fan motor comprising same, the stator comprising: a stator core including a back yoke and a plurality of teeth that extend to protrude in the radius direction from the inner surface of the back yoke toward the center of the back yoke; a plurality of stator coils respectively wound around the plurality of teeth; and a plurality of teeth insulators for insulating the plurality of teeth from the plurality of stator coils, wherein each of the plurality of teeth insulators comprises: an insulator body for encompassing the teeth; and a plurality of heat-dissipating fins formed to protrude from the side surface of the insulator body so as to expand a contact area with the stator coil, and thus discharge heat of the stator coil, thereby maximizing cooling of coils through convection and conduction.
