Abstract: A rotor for a rotary electric machine includes a rotor shaft configured to rotate around an axis of rotation, a rotor body formed of a stack of laminations having a plurality of teeth projecting radially and being configured to be mounted coaxially on the rotor shaft. A field coil is wound around each tooth of the plurality of teeth. At least one tooth of the plurality of teeth includes at least one weld seam on a lateral face of the corresponding tooth, the lateral face extending radially and axially along the axis of rotation.

Abstract: Stator for an electric machine, having a stator core with two axial end sides, a stator winding which extends through the stator core in the axial direction and is formed from a plurality of conductor segments, and covers of a first and a second type. The conductor segments have, at one of the end sides, end sections which are electrically conductively and mechanically connected to one another in pairs to form end section arrangements. The covers of the first type each cover at least two end section arrangements at their free end, and the covers of the second type each cover at least one end section arrangement at their free end.
