摘要： The present invention relates to a motor assembly and a hair dryer having same. The motor assembly of the present invention comprises: an impeller; an outer housing and an inner housing arranged concentrically; a stator accommodated inside the inner housing; a rotor disposed inside the stator; a bearing supporting a rotary shaft of the rotor; a bracket having a bearing accommodating part in which the bearing is accommodated, and a plurality of bridges which are spaced apart from the outer surface of the bearing accommodating part in a circumferential direction thereof and protrude in an axial direction thereof so as to be coupled to the inner housing; and a vortex suppressing part blocking empty spaces between the plurality of bridges so that generation of air vortices can be suppressed. Thereby, it is possible to suppress vortex generation in a downstream region of the impeller, and flow loss caused by the vortex generation can be reduced.

摘要： 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.

摘要： A fan motor comprises 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.
