WIPO Patent Application WO/2022/035015
Kind Code:
A1
Abstract:
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 for cooling a stator can be formed inside a stator slot, and thus cooling of the stator can be facilitated.
