Zusammenfassung:The invention relates to a stator (2) for an electric machine (3), in particular for electric drive motors for motor vehicles, said stator (2) having an electric winding (5) that comprises electric conductors (4) and forms a respective winding head (6) at the end faces of the stator (2). A temperature sensor (7), which is used to measure a temperature and which has a temperature measuring element (8) and in particular a sensor casing (22) that surrounds the temperature measuring element (8), can be secured in a receiving area (9) of a receiving element (10) that is connected to an electric conductor (4) of the electric winding (5) in the region of one of the winding heads (6), in particular the receiving element is secured thereto. According to the invention, at least one spring ring (15) is provided that is used to secure the temperature sensor (7) in the receiving chamber (9) of the receiving element (10), and in the installed state, the spring ring (15) at least partly surrounds the temperature sensor (7) and is at least partly arranged in the receiving chamber (9) of the receiving element (10) such that the temperature measuring element (8) is connected to the receiving element (10) in a thermally conductive manner.
