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.
