Claim 6:
7. The method of claim 6, wherein, when a device for modeling one or more die-pressed hairpins prior to assembly thereof in a winding set, wherein
each die-pressed hairpin has an insulating coating and comprises two or more legs having corresponding pitches such that they are insertable into a stator or rotor core, and a bridge-like head portion, said two or more legs including respective one or more free ends opposite to said bridge-like head portion, wherein an angle between a first plane passing through at least three points of said two or more legs and a second plane passing through ends of the bridge-like head portion and through at least one point of the bridge-like head portion takes a predetermined value (γ), the device comprising:
one circular frame which includes one or more respective housing portions configured to partially house said one or more die-pressed hairpins having said corresponding pitches, each housing portion being integrally connected to or formed in said one circular frame; and
a circular spreader wedge having a pushing tapered side configured to push and deform said one or more die-pressed hairpins;

wherein:
said one or more respective housing portions are configured so that when said one or more die-pressed hairpins are a plurality of die-pressed hairpins, they are housable so as to be at a predetermined angular distance from one another along the one circular frame and spaced apart from one another;
said circular spreader wedge is configured and adapted to move downwardly from an initial position above the one circular frame, in which the pushing tapered side does not apply any action on said one or more die-pressed hairpins, to a final deformation position of said one or more die-pressed hairpins, wherein said angle takes a value (γ+x) different from said predetermined value (γ) is provided in step S1, said one or more die-pressed hairpins in said step S2 are inserted so that said head portions are at a predetermined angular distance from one another along the one circular frame.
