A control device for controlling an electric motor of an electrical device may include a flat plate and a power electronics. The plate may extend in a plate plane. The power electronics may include a plurality of electronic components arranged and interconnected on the plate. The power electronics may have at least one electronic power component that produces waste heat during operation. The at least one electronic power component may be arranged such that a body of the at least one electronic power component penetrates the plate plane. A plurality of power connections, via which the at least one electronic power component may be interconnected to the plurality of electronic components, may be arranged at an edge of the plate.

Control device for controlling an electric motor comprising a plate penetrated by an electronic power component

An electric fluid pump may include a pump housing and an electric motor. A rotor may have a rotor shaft and may be mounted in a rotatable manner in a stator body, which may have a stator embedded at least regionally therein. The pump housing may be subdivided into a dry and a wet region containing the rotor. The rotor shaft may be mounted on a bottom side and may be connected to a pump impeller on a pump-impeller side, facing away from the bottom side. The pump housing may have, on the pump-impeller side, an aperture out of which the rotor shaft may project. The pump housing may have an internal first bearing collar arranged around the aperture, the dry region located radially around the first bearing collar, and an outside diameter of the first bearing collar being less than a maximum diameter of the rotor.

Fluid pump having an internal bearing collar and method for assembling the fluid pump

A housing for accommodating electrical components, in particular in a liquid pump, includes a housing pot including a bottom and a surrounding wall protruding from the bottom, as well as a housing cover closing the housing pot, including a shoulder protruding in the direction of the bottom. A simplified and cost-efficient production of the housing as well as an increased operational safety of the liquid pump are attained in that the housing cover forms a caulking connection with the surrounding wall of the housing pot with the help of at least one recess formed in the shoulder. The disclosure furthermore relates to a liquid pump including a housing of this type as well as a method for producing a liquid pump of this type.

Housing

An electric fluid pump may include a pump housing and an electric motor arranged in the pump housing. A rotor of the electric motor may have a rotor shaft and may be mounted in a stator of the electric motor so as to be rotatable about an axis of rotation. The pump housing may be divided into a dry region and a wet region in which the rotor may be disposed. The dry region and the wet region may be separated by a stator support piece which may at least regionally enclose the stator.

Electric fluid pump

A fluid pump for conveying a fluid may include an internal rotor rotatable about an axis of rotation relative to an external stator and an impeller connected to the internal rotor in a rotationally fixed manner configured to convey a fluid. The internal rotor may include a rotor receiving sleeve having a base body. The base body may include a receiving chamber configured to receive an anchor unit. The internal rotor may further include a bearing bushing penetrating the rotor receiving sleeve coaxially to the axis of rotation. The bearing bushing may be configured to receive a rotor shaft. The impeller may be directly connected to the rotor receiving sleeve in a rotationally fixed manner.
