A motor includes a rotor rotatable about a central axis and a stator including coils. The stator opposes the rotor with a gap interposed therebetween. A housing defines at least a portion of a closed chamber in which a cooling medium is housed. Heat dissipation portions are able to release heat of the cooling medium in the closed chamber to an outside. A pressure adjustment portion is able to adjust a pressure in the closed chamber. At least a portion of the coils and the rotor is housed in the closed chamber.
