    Abstract: A vacuum cleaner includes a driven impeller that moves working air for the vacuum cleaner. A first housing includes a first wall and a second housing includes a second wall opposite the first wall, and an outlet for the working air. The impeller rotates and draws the working air through an opening and directs the working air radially outwardly toward the first wall and then through an annular passage formed between the first wall and the second wall. The annular passage restricts the flow of working air to provide back pressure on the impeller.

    Abstract: The invention relates to a high-speed electric motor (2) with a rotor (3), a stator (4) and an impeller (6) fastened to a rotor shaft (5), wherein due to a diversion, the motor cool air fed through the impeller (6) flows partially through the motor (2) and partially externally on a substantially cylindrical motor housing (7). Diversion is achieved by a diffuser (45) working together with a fan casing (50), and the diffuser (45) has a diffuser plate (51) on which return blades (48) turned towards a motor space (46) are constructed. A substantially annular outlet (43) for conveying cool air externally on the motor housing (7) is associated with the diffuser (45). To provide an improved, high-speed electric motor of said type, it is proposed that the width (h3) of the outlet (43) is approximately 50 to 70 % of a vertical distance (h4) (when measured parallel to the rotor shaft (5)) of the diffuser plate (51) from the outlet (43).
