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).
