摘要： The present invention concerns an electronic housing for an electric motor, consisting of a housing holder part with a housing floor and a housing wall comprising the housing floor. A housing opening lies opposite the housing floor. Arranged in the housing holder part is a motor electronic component with an electronic printed circuit board, which is arranged parallel to the opening plane of the housing opening. Detachably arranged on the electronic printed circuit board or on the motor electronic component, on a side of the electronic printed circuit board facing away from the housing floor is a contact protecting component, which covers this surface, from an electrically insulating material, which has at least partially a grid structure as an air outlet.

摘要： A fan includes a sealed electronics housing, in which a printed circuit board having electronic components is arranged. The electronics housing is divided into an upper region and a lower region. A cooling wheel which is arranged in the lower region is axially adjacent to the printed circuit board. The printed circuit board has at least one central opening and a plurality of peripheral-edge openings or gaps in order to bring the upper region into fluid communication with the lower region. Air is drawn out of the upper region into the lower region by the cooling wheel via the at least one central opening and, via the plurality of peripheral-edge openings or gaps. The air is fed back into the upper region. An air circuit having at least one air flow develops along a surface of the printed circuit board on which the electronic components are arranged.

摘要： A stator (1) for an electric motor has a modular stator body (2) with at least two stator cores (10, 20) arranged axially in series. Each core (10, 20) is form from a plurality of stacked electrical laminations (11, 21). This forms winding poles (16, 26) with radially extending winding webs (17, 27). The stator cores (10, 20) each have a separate overmolding (U1, U2).

摘要： An electronics unit and a plug-in junction box for plug-in connection of a plug-in connector integrated therein in the plug-in direction (S) into a plug-compatible socket of an electronics housing of an electronics unit of an electric motor. The junction box has a housing with a pot-like accommodation region delimited by housing walls for accommodating a contact carrier of the plug-in connector. A plurality of hollow-cylindrical screw bushings extending in the plug-in direction (S) are provided in the accommodation region. At a plurality of positions corresponding to those positions of the screw bushings, the contact carrier has externally located guide elements at which the contact carrier can be guided into its final assembly position, and in the final assembly position, the respective guide elements at least partially engage around the cylindrical screw bushings.
