Embodiment Construction

[0029] figure 1 A schematic sectional view of an engine compartment of a motor vehicle is shown, in which an electric machine 10 known from the prior art is arranged. The electric machine 10 includes a core region 18 in which a rotor is mounted rotatably about a rotor axis of rotation 22 . The core region 18 has a circular cross-section with a diameter D1 and its perimeter is delimited by a circumferential profile 20 . In addition to the rotor, the core region 18 can include further components, in particular a stator, coil windings and a stator carrier. In this case, the coil winding can extend, for example, over the entire circumferential area of ​​the core region 18 inside the circumferential contour 20 . The coil windings can also be arranged only in partial sections of the circumferential contour 20 . This may be the case, for example, if the electric machine 10 is a three-phase electric machine. Furthermore, the electric machine 10 comprises cooling medium channels 24...

Abstract

#CMT# # / CMT# The machine (10) has a rotor arranged in a core region (18) that includes a circular cross section, where the core region is limited by a periphery contour (20). The rotor is rotated in a rotor rotational axle (22), and coolant channels (24) are arranged axially and parallely to the rotor rotational axle. The coolant channels are arranged along the periphery contour on an outer region of the core region for cooling the machine. One of the coolant channels includes various sizes, where the coolant channels are closed in circumference. #CMT# : # / CMT# An independent claim is also included for a method for designing a motor vehicle. #CMT#USE : # / CMT# Electrical machine for a motor vehicle (claimed). #CMT#ADVANTAGE : # / CMT# The coolant channels are arranged along the periphery contour on the outer region of the core region for cooling the machine, where one of the coolant channels includes various sizes, thus allowing the machine to be installed in the motor vehicle in a simple, space saving and maintenance-free manner with improved cooling performance. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a schematic sectional view of an electric machine in a motor chamber of a motor vehicle. 10 : Electrical machine 18 : Core region 20 : Periphery contour 22 : Rotor rotational axle 24 : Coolant channels.

Description

technical field [0001] The invention relates to an electric motor for a motor vehicle, the electric motor having a rotor and cooling medium channels, the rotor being located in the region of a core which is circular in cross-section and delimited by a peripheral contour, wherein the rotor is rotatable about a rotor axis of rotation, cooling A medium channel runs axially parallel to the rotor axis of rotation, said cooling medium channel being arranged outside the core region along the circumferential contour for cooling the electric machine. The invention also relates to an electric machine according to the preamble of claim 5 . Furthermore, the invention relates to a motor vehicle with an electric machine and a method for designing a motor vehicle. Background technique [0002] Generally, electric machines for motor vehicles have a core region which includes a rotatably mounted rotor and which determines the characteristic parameters of the electric machine, such as power ...
