Abstract
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.
