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.

Welding of a stack of laminations for a rotor

An electromagnetic pole () for a rotary electric machine is disclosed. The pole has a tooth () comprising a tooth body (), the tooth () being radially oriented and the tooth () comprising a recess (), a coil () comprising a plurality of wire turns () wound around the tooth () between a first radial end () and a second radial end (), the wire turns () which are the most distant from the tooth body () between the first radial end () and the second radial end (), forming an outer wire layer (), the coil () comprising a bracing wire (), the bracing wire () being wound on the outer wire layer () from the first radial end () to the second radial end () in less than one turn around the tooth () so as to hold in position the outer wire layer ().
