The invention relates to an electric motor, in particular for a motor vehicle, comprising a housing (), a shaft () having an axle (), a stator and a rotor, at least one channel () for conducting a coolant for cooling the electric motor (), wherein the geometry of the alignment of at least one section () of the at least one channel () is designed such that the coolant flows in the direction of the axle () of the shaft () through the at least one channel (), having a deviation of less than 40&#xb0;.

Electrical machine comprising cooling channels

A method for manufacturing an electric machine, made up of a housing, a stator accommodated in the housing, which is formed from a stator body and stator windings, a rotor, which is supported in the housing so as to be rotatable about a rotor axis, and a bearing support fastened on the housing, includes a housing foam part manufactured from at least three individual foam parts and a housing cast blank manufactured using the housing foam part in accordance with a lost foam casting method. Individual foam parts are made up of a center disk having an essentially hollow-cylindrical design and forming an intermediate piece of a housing foam part, an annular disk having an essentially hollow-cylindrical design and forming another intermediate piece of the housing foam part, and a bearing support disk having an essentially cup-shaped design and forming an end of the housing foam part.
