Abstract (en)

[origin: WO2022175183A1] The invention relates to a method for producing an electric motor housing, comprising the steps of: (a) positioning at least one stator part (30) in a support body interior chamber of a support body (22), (b) arranging a casting core (42) on the support body (22), (c) subsequently casting liquid metal around the support body (22) and the casting core (42), so that a rotationally fixed connection is formed between the stator part (30) and a casting (26) which is produced by the solidification of the liquid metal.
