Abstract: A stator structure according to an embodiment includes a stator core having a plurality of teeth; insulators configured to cover the teeth; a coil wound around each of the teeth with the insulators interposed therebetween; and first and second coil covers configured to cover the coil, each of the first and second coil covers being formed in an annular shape. The insulators have respective flange parts configured to cover respective distal end portions of the teeth. Each of the first and second coil covers has a first peripheral wall. The first peripheral wall of the first coil cover and the flange part located on one side of the insulator are arranged to face each other with a space therebetween. The first peripheral wall of the second coil cover and the flange part located on the other side of the insulator are arranged to face each other with a space therebetween.

Abstract: A fan motor according to an embodiment includes a bearing holder, a stator, a circuit board, and a synthetic resin. The stator is mounted at an outer circumference of the bearing holder. The circuit board is electrically connected to a coil of the stator, is mounted at a surface of the base part at an opposite side to the bearing holder, and extends from a base part to a connector housing. The synthetic resin seals the bearing holder, the stator, and the circuit board, except for both end faces of the bearing holder. The connector housing has a gate opening that is injected with the synthetic resin at the time of sealing and ribs that are at an opposite side to the gate opening with the circuit board between the ribs, and tops of the ribs making contact with the circuit board.
