A connecting element () interacting with a fan blade () to transfer torque of a drive to the fan blade (). An attachment portion () connects the connecting element () with the fan blade. The attachment portion () forms an outer edge portion () adjoining the outer contour of the connecting element (). The attachment portion () cross-sectional shape is designed to taper toward the outer edge in at least some portions.

A rotating electric machine () having a stator () in a housing () and a rotor () supported by a shaft (). The housing () circumferential wall () and first and second axially opposing end walls () support bearing flanges with bearings () for the shaft (). Two cooling fan impellers () are connected to the shaft (). An inner cooling fan impeller () positioned inside the housing () generates an inner cooling air circuit (A) inside the housing (). An outer cooling fan impeller () provided outside the housing (), generates an outer cooling air flow (B). The first end wall () is formed with a thermal conductivity of at least a specified value and has an outer cooling rib geometry () on its outer side facing the outer cooling fan impeller (), and an inner cooling rib geometry () on its opposing inner side.

Rotating electrical machine

The invention relates to a fitting arrangement for an antivibration mounting of an electromotor ( ) on a load-bearing component by means of several interelements ( ) arranged distributed around the perimeter and consisting of an elastic material. To always achieve an optimum vibration isolation independently of the motor's fitting position, it is provided that the interelements ( ) are designed as oblong, radially aligned web elements ( ) and are arranged axially, clamped under elastic prestress, between a mounting surface ( ) on the motor side.

Fitting arrangement for an antivibration mounting for an electromotor

The present invention relates to an arrangement for the vibration-isolating mounting of an electric motor (2) on a support part (6) via an essentially disk-shaped support element (12). The support element (12) has a motor-holding section (24) for connection to the electric motor (2) and a support-holding section (26) for connection to the support part (6), and the two holding sections (24, 26) are connected via elastic, web-like connecting pieces (28). The connecting pieces (28) are designed such that the two holding sections (24, 26) are elastically movable relative to each other three-dimensionally in all directions in space, specifically axially, radially and tangentially, over a certain movement play. The support element (12) has integrated stop means for the three-dimensional limiting of the elastic relative movements of the holding sections (24, 26) and/or an additional mass (110) to influence the vibration behavior.
