More Information
Summary:The invention relates to an electric machine (1) having: a rotor (3); a stator (2); multiple winding pieces (5) which are in the form of hollow conductors, form different coils of a winding (4) of the electric machine (1) and are each part of a coolant circuit of the electric machine (1); and multiple external phase connections (L1-L3) which are electrically connected to the winding pieces (5). According to the invention, a hydraulic connection part (15) to which a number of the winding pieces (5) are hydraulically connected, and a seal (27) which has multiple passages (28), in each of which an end portion (8) of one of the winding pieces (5) is situated, are provided, the hydraulic connection part (15) and the seal (27) having opposing surfaces (29, 30) which rest against each other in order to ensure sealing of the individual connections of the winding pieces (5) to the hydraulic connection part (15).
