As shown in FIG. 14, the air conditioner 300 includes an outdoor unit 310, an indoor unit 320, and a refrigerant pipe 330 for circulating a refrigerant between the outdoor unit 310 and the indoor unit 320. .

  The outdoor unit 310 has a compressor 311, a heat exchanger 312, a fan 313, and an electric motor 314 for rotating the fan 313. The motor 314 and the fan 313 constitute a blower for flowing air to the heat exchanger 312. The indoor unit 320 has a heat exchanger 321, a fan 322, and an electric motor 323 for rotating the fan 322.

  The motor 323 and the fan 322 constitute a blower for flowing air to the heat exchanger 321. In the air conditioner 300 according to the third embodiment, at least one of the motor 314 and the motor 323 is configured by the motor 200 according to the second embodiment. In the air conditioner 300 according to Embodiment 3, either the cooling operation of blowing cold air from the indoor unit 320 or the heating operation of blowing warm air from the indoor unit 320 can be selectively performed. An air conditioner 300 according to the third embodiment is the same as a conventional air conditioner except that the motor 200 according to the second embodiment is employed as at least one of the motor 314 and the motor 323. .

  According to the air conditioner 300 according to the third embodiment, in addition to the effects obtained by the stator 100 described in the first embodiment and the effects obtained by the motor 200 described in the second embodiment, The effect of improving the quality of the air conditioner 300 can be obtained.

  The air conditioner to which the present invention can be applied is not limited to the indoor air conditioner as shown in FIG. The present invention is applicable to various devices including an electric motor such as an air conditioner for a freezer storage and an air conditioner for a refrigerator.
