Abstract
A stator of an electric machine includes: a laminated stator core having sheet-metal blanks which have apertures, the apertures being closed radially on an inside thereof by a web when viewed in a cross section extending in a radial direction of the stator; and stator windings, which are accommodated in the apertures of the laminated stator core. The web which closes a respective aperture radially on the inside is plastically deformed so as to introduce a mechanical stress into the web.
