Abstract: The invention relates to an electric motor comprising a rotor, a stator (1) and an electronic housing (12), the installation space (13) of which accommodates electrical/electronic components (18). At least part of these components (18) is seated on a printed circuit board (19). A fan wheel (21) is located inside the installation space. It is arranged and designed in such a manner that it generates a cooling circuit stream in the installation space (13), in which the air is drawn in centrally from the fan wheel (21) and is discharged approximately radially to the outside. As a result of this defined cooling air stream, the components (18) are evenly cooled in the installation space (13). The fan wheel (21) consists at least of a base body which comprises blades (22) located between a cover disc (24) and a base disc (23). In this way, the fan wheel (21) generates a directed cooling air stream for cooling the heat-generating components.

Abstract: The invention relates to an electric motor having a stator and an electronics compartment which receives electric/electronic structural parts. Said electric motor is accommodated in an electronics housing and can be closed by a housing cover. In order to maintain leakage paths and/or air paths between the housing cover and the electric/electronic structural parts, the electric motor has an intermediate insulating part (1) which is made of an electrically insulating plastic and has a supporting part as hard component and at least one soft component as sealing part (14, 25). The soft component is connected cohesively and/or by positive engagement to the hard component. The intermediate insulating part (1) has at least one pressing element (33) by which at least one heat-generating structural part is pressed against a cooling surface. The intermediate insulating part (1) has a hood-shaped support which is made of a hard, electrically insulating plastic.

Abstract: An electric motor has a stator bushing in which components that generate heat are disposed. A rotor housing that has at least one air conveying element is rotatably connected to the stator bushing. The air conveying element has a top side that is facing the stator bushing and that is at least basically smooth. The air conveying element has an annular disk that is provided with the basically smooth top side. The air conveying element has flow guiding elements that are radially extending ribs provided on the bottom side of the annular disk.
