Abstract: A segmented stator has a plurality of individual teeth (12) connected to one another in the direction of rotation. Each individual tooth (12) has a connecting portion (17) to produce a nonpositive mechanical connection with at least one directly adjacent individual tooth (12). The respective connecting portion (17) has a groove-shaped fastening contour (18, 18a, 19, 19a), at least on one connecting side (17a, 17b), facing toward the directly adjacent individual tooth (12). The fastening contour (18, 18a, 19, 19a) of an adjacent individual tooth (12) can be connected to its connecting portion (17), such that a nonpositive connection is produced which ensures a magnetic flux.

Abstract: A component holding device for the fixed-position arrangement of an electric component on a circuit board, having a support side for receiving the electric component, wherein at least one pretensioning element and at least one first latching element for the fixed-position latching of the electric component are provided on the support side, and the at least one pretensioning element is designed to exert a pretensioning force on the electric component, which presses the electric component against the at least one first latching element, and having at least one second latching element on an underside lying opposite the support side, wherein the second latching element is designed to fix the component holding device in a predefined location in a fixed position on the circuit board.

Abstract: A holder has a holding body, a spring member, and a tensioning member. The holding body forms a cavity to receive the electronic component. A connecting section has a thermally conductive heat conductive section adjacent to the cavity. The tensioning member tensions the spring member. The spring member supports itself in a tensioned state on a counter-holding member. The spring member moves a connecting surface of the holding body to the cooling body and/or presses it against the cooling body.

Abstract: A holder (1) for thermally contacting a component (42). The holder (1) has a holding body (20), a spring member (30), and a tensioning member (10). The holding body (20) forms a cavity that corresponds to the electronic component (42) to receive the electronic component (42). A connecting section (21) has a thermally conductive heat conductive section (22) adjacent to the cavity. The tensioning member (10) is configured to tension the spring member (30). The spring member (30) supports itself in a tensioned state on a counter-holding member (51). The spring member (30) applies a force onto the holding body (20) and/or onto the component (42). The spring member (30) moves a connecting surface (28) of the holding body (20) to the cooling body (54) and/or presses it against the cooling body.

Abstract: The invention concerns a housing of a fan with an external covering, wherein the housing comprises a housing body to accommodate fan components, and a radial exterior face of the housing body is surrounded by the external covering in the circumferential direction over its full surface, so that a radial exterior surface of the housing is formed by an exterior surface of the external covering, and the external covering is detachably fastened to the housing body.

Abstract: A connecting system for a stator assembly (2) and a plug housing (3) can be inserted into an opening in a stator housing (4). A plug housing receptacle (6) is provided in the stator assembly (2). The plug housing (3) engages the housing receptacle such that it is movable relative to the stator assembly (2) in at least two perpendicular directions when mounted.

Abstract: A housing for a fan or blower, in particular an axial fan, includes a wall ring (2) having an inlet nozzle section (3), an outer diffuser (6) having an inlet flow opening (7) and an outlet flow opening (8), and a holder for an electric motor (9) of the fan. The holder is arranged in an inner space of the housing. The outer diffuser (6) is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts (14) that are fastened to an inner circumferential surface of the outer diffuser (6) by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (7). The struts can be installed by their other end to a motor flange (16) of the motor housing (17) of the electric motor (9).
