Claim:
1. A synchronous electric motor comprising: a central stator; an external rotor; and a plurality of reels for the stator windings arranged according to a predefined pitch and intended to receive respective windings of a conducting wire, each reel comprising a base portion and a winding portion, wherein said stator comprises a mobile body which can be articulated from an initial arrangement, suitable for receiving the conducting wire by winding on said reels, to a final arrangement of substantially annular configuration in which the wire wound on the reels has ends electrically connected to corresponding terminals of an electronic printed circuit board associated with the stator of the motor, wherein said mobile body comprises said reels and connection portions between the base portions of adjacent reels, each connection portion having a first link, hingedly attached at the base portion of a reel, and a second link hingedly attached at the base portion of the adjacent reel, said first and second links being connected together at a bending point, a line of weakening being provided that allows bending of said connection portion at said bending point, wherein, in the initial arrangement, each connection portion is set in a first configuration, in which said first and second links are substantially linearly aligned and define a first pitch between the base portions of adjacent reels; wherein, in the final arrangement, each connection portion is set in a second configuration, in which said first and second links form an acute angle, the connecting portion being folded about the bending point, with the bending point toward, the centre of the substantially annular configuration and ends of the links attached to the reels pointing away from the centre of the substantially annular configuration, defining a second pitch between the base portions of adjacent reels; wherein said first pitch is longer than said second pitch thus reducing a spacing between the base portions in the final arrangement.
