The present invention relates to a fan motor comprising: a housing; a vane hub received in the housing; an insulator mounted inside the vane hub to insulate a stator comprising a stator core and a stator coil wound on the stator core; and a lower bracket coupled to the insulator, wherein a plurality of power line lead-out holes are formed in the lower bracket so as to allow a power line extending from the stator coil to pass therethrough, and a plurality of air holes are formed in the circumferential direction between the respective power line lead-out holes so as to allow air to be suctioned toward the stator. Accordingly, a flow channel of air to for cooling a stator can be formed inside a stator slot, and thus cooling of the stator can be facilitated.

Fan motor

A fan motor includes a motor mount, a motor part accommodated in an inner space of the motor mount, and an impeller disposed above the motor mount. The motor mount defines: an air discharge opening configured to discharge air discharged from the impeller to an outer space of the motor mount; a cooling flow path outlet disposed at the upper side of the motor mount at a position between the impeller and the air discharge opening; and a first cooling flow path inlet disposed at a position below the air discharge opening and the cooling flow path outlet. The fan motor further includes a guide that is configured to direct, to an upward direction, at least a portion of air that is discharged through the air discharge opening and introduced to the inner space through the first cooling flow path inlet.
