摘要： The invention relates to a blade edge of at least one blade of an air-conveying wheel with an axial-side blade edge contour which extends from the blade leading edge to the blade trailing edge along a curve. The blade edge contour has at least one front section which adjoins the blade leading edge in the radial direction, a rear section which adjoins the blade trailing edge in the radial direction, and a central section which lies between the front section and the rear section. The blade edge contour has an S-shaped curve progression in the central section in a lateral cross-sectional view, thus increasing the axial height of the blade in the direction of the blade trailing edge.

摘要： The present invention relates to a rotating electrical machine (1) in the form of a generator or motor, having a stator (4) which is arranged in a housing (2) and a rotor (10) which is mounted such that it can rotate about a rotation axis (8) via a shaft (6). The housing (2) has a peripheral wall (12) and two end walls (14, 16) which are situated axially opposite one another and are in the form of bearing flanges with rotary mounts (18) for the shaft (6). Two cooling fan impellers (20, 22) are connected to the shaft (6), specifically firstly, within the housing (2), an inner cooling fan impeller (20) which generates an inner cooling air circuit (A) within the housing (2) when it rotates, and secondly, outside the housing (2), an outer cooling fan impeller (22) which generates a cooling air flow (B) which flows over the housing (2) when it rotates. The first end wall (14) which is arranged on the side of the outer cooling fan impeller (22) is formed with a high degree of thermal conductivity of at least (formula I), and has, on its outer face which faces the outer cooling fan impeller (22), an outer cooling rib geometry (28) and also, on its opposite inner face, an inner cooling rib geometry (30).

摘要： The invention relates to an electric motor comprising an electronics housing in which motor electronics are accommodated, a stator bush for accommodating a stator, which bush is axially adjacent to the electronics housing, and a cooling impeller which is axially adjacent to the stator bush and which can be driven via a rotor, wherein an axial through-channel that is connected for flow is provided in the stator bush and in the electronics housing, through which channel a cooling air flow generated by the cooling impeller can be conveyed, and wherein the cooling impeller has a blade geometry such that in normal operation of the electric motor, the cooling air flow is drawn in radially from outside at a circumferentially radial air inlet of the cooling impeller and is pressed through the through-channel in an axial direction.

摘要： The invention relates to a diffuser (3) for a fan (2) of axial, radial, or diagonal construction, having an inlet opening (10) and an outlet opening (20) for a gaseous medium flowing through a diffuser interior (I) enclosed by an outer housing (30) in an axially directed main flow direction (S) from the inlet opening (10) to the outlet opening (20), wherein the cross section (21) of the outlet opening (20) is greater than the cross section (11) of the inlet opening (10) and the cross section of the diffuser interior (I) increases from the cross section (11) of the inlet opening to the cross section (21) of the outlet opening (20), wherein the outer housing (30) forms an outer diffuser part (AD) bounding the diffuser interior (I) on the outside. In order to achieve improvement of the operating behavior with respect to efficiency and noise, according to the invention the cross section of the outer diffuser part (AD) transitions along the main flow direction (S) from a circular cross section (31) at the inlet opening (10) to a non-circular cross section (32) at the outlet opening (20).
