摘要： A motor 1 includes a stator 3, a rotor 2, and a housing 52. The housing 52 includes a one-side space 52a, an other-side space 52b, a one-side communication hole 52c, and an other-side communication hole 52d. The one-side space 52a and the other-side space 52b communicate with each other via a gap G, the one-side communication hole is connected to a first airflow generator 64, and the other-side communication hole is connected to a second airflow generator 65. The motor 1 includes a forced inflow hole 52c1 connected to the first airflow generator 64 and a natural exhaust hole 52c2 through which air is naturally exhausted as the one-side communication hole, and includes a forced exhaust hole 52d1 connected to the second airflow generator 65 and a natural intake hole 52d2 through which air is naturally sucked into inside of the other-side space 52b as the other-side communication hole.
