    Abstract: The invention relates to a radial impeller (1), preferably on an electric motor (10), especially an electric vacuum cleaner motor, with an impeller disc (8) on which are fitted preferably curved blades (2) with an outer curve (3) and an inner curve (4). Through apertures (6) are provided in the impeller disc (8). To reduce noise, the invention proposes that the through apertures (6) allocated to a blade (2) be formed on the outer curve (3).

    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).

    Abstract: An air stream, in particular for cooling, may be applied to an electric motor (3), in particular a universal motor. A movable, preferably rotary flow guiding part is arranged in a flowpath of the air stream. The air stream passes through at least part of the flow guiding part and is deflected within the flow guiding part. A pocket (10) is designed for receiving the deflected air stream. In order to effectively filter out the finest particles, in particular coal dust particles, with as simple a design as possible, one wall (11) of the pocket may be moved together with the flow guiding path at substantially the same (angular) speed. The flow guiding path is arranged in the flowpath of the air stream preferably downstream of the moving parts of the electric motor.

    Abstract: The invention relates to an electric plug connection (1) with a plug holder (7) and a pin (3), especially a round-section pin (3), in which the plug holder (7) has a holding compartment in which is an axially compressible coil spring (2) having individual turns (5, 6) with the turns (5) largely having the same main diameter (dh). In order to reduce wear to the minimum even with frequent plug-in cycles and also not to increase the plugging force excessively, the invention proposes that the main diameter (dh) be larger than the outside diameter (d) of the pin (3) and that one or a few of the contact windings (6) have a smaller contact diameter than the main diameter (dh) and than the outside diameter (d) of the pin (3).
