Abstract
A method for producing a pole housing for an electric motor includes preparing a tube lateral surface from a preferably pre-galvanized sheet metal material and shaping the tube lateral surface to form a cylindrical pole tube from the sheet metal material in such a way that longitudinal edges of the tube lateral surface extended in the tube longitudinal direction face towards one another. The longitudinal edges of the tube lateral surface are joined to one another to form a closed pole tube. A previously-provided cover is form-lockingly and/or force-lockingly fastened as a bearing plate to a front end face of the pole tube and a fluid-impermeable joint is formed between the cover and the pole tube. A pole housing for an electric motor and an electric motor having a pole housing are also provided.
