Abstract

A stator bar for an electrical machine (1), having two opposed ends (7), is provided with a main body (10) defined by: a plurality of substantially parallel elongated conductive elements (15) stacked on columns (16) that are set alongside one another, in which each elongated conductive element (15) extends along a path having a plurality of transpositions (20) from one column (16) to the other; and a filling element (18) adapted for filling empty spaces of the main body (10) generated by the transpositions (20); the stator bar (6) is moreover provided with at least one lamina (12) made of conductive material having one end (24) electrically connected to an elongated conductive element (15) of the main body (10).
