Disclosed is an electric machine () comprising a pole housing () and a printed circuit board () for controlling the electric machine (). The circuit board () is arranged on a flanged side () of the pole housing (), and a protective wall () which protects the circuit board () from loose small parts is arranged between the circuit board () and the pole housing ().

Electric machine comprising a pole housing

Electrical machine () having a shielding plate (), wherein the electrical machine () comprises a housing part () in which is arranged an electronic unit (), and said electrical machine also comprises a metal heat sink () that is arranged on the housing part (), wherein the electronic unit () is arranged between the shielding plate () and the heat sink ().

Electrical machine having a shielding plate

A fan arrangement (), in particular for cooling an engine system, comprising: an impeller () having one or more blades () which in operation convey a medium in the direction of an axis of rotation of the impeller () from an inlet side (E) to an outlet side (A); a housing shroud () having a base part () which extends in the direction of the axis of rotation and surrounds the impeller () completely or partially, wherein, on an end of the base part () oriented towards the outlet side (A) of the impeller (), there is provided a discharge flow element () which extends radially outwards from the end of the base part ().

Fan arrangement

A fan () comprises a fan hub (), fan blades () which are mounted on the fan hub (), and a drive motor having an outer rotor (), wherein the outer rotor () is arranged inside the fan hub (). The outer rotor () is arranged in the fan hub () in such a way that the outer rotor () is supported in a radially outward direction on the radial outer wall () of the fan hub (), by means of cooling fins () which are formed integrally with the fan hub ().

Fan module

A fan includes a hub and blades. A first edge of each blade is proximate an open end of the hub. A first rib is coupled to the hub and substantially aligned with a first plane intersecting the central axis and an intersection of the first edge of the first blade with the hub. The first plane is angularly spaced from a reference plane intersecting the central axis and an intersection of the first edge of the second blade with the hub. An angular spacing between the first plane and the reference plane defines one sector. A second rib is aligned with a second plane angularly positioned between the first plane and the reference plane at a location less than or equal to about (1/nR&#x2212;0.05) sectors from the first plane, in which nR equals the number of ribs divided by the number of blades.
