Beschreibung
Zusammenfassung:	Provided are a motor and a vacuum cleaner. The motor includes a housing, an impeller (30), a diffuser (40), a rotor assembly (50) and a stator assembly (60), the motor has an air inlet and an air outlet, the air inlet is disposed on the housing, the impeller (30) and the diffuser (40) are disposed in the housing, the impeller (30) is disposed adjacent to the air inlet and is connected to the rotor assembly (50), the diffuser (40) is located downstream of the impeller (30), the stator assembly (60) is located downstream of the diffuser (40), the housing includes a front housing (10) and a rear housing (20) which are connected to each other, a first air duct is enclosed among a rear inner wall of the front housing (10), a front inner wall of the rear housing (20) and the diffuser (40), the first air duct is in communication with an outlet of the impeller (30) and the air outlet, and an inner diameter size of the rear end of the rear inner wall is less than or equal to an inner diameter size of the front end of the front inner wall. In the technical solution of the motor, energy loss and noise can be reduced.
