  • Method for producing wound stator of rotary electrical machine
    Patent number: 10637335
    Abstract: The invention relates mainly to a method for producing a wound stator (1), including: a step of preparing a phase winding; an insertion step which includes inserting the phase winding into a corresponding series of notches (5) in said stator (1); and an intermediate step of forming lead out wires of the winding (26) each extending between two notches (5) of each series of the inserted phase windings, by applying a first radial force (F1) from an axis (X) of the stator (1) toward the outside of the stator (1), wherein the method also comprises a step of positioning a bearing surface facing at least one notch (5) such as to apply a second radial force (F2) resulting from the application of the first force (F1) from the outside toward the axis (X) of the stator (1).
