1. Rotating electrical machine with assembled stator, the stator being formed of a pile of sheets obtained by punching from a strip of magnetic sheet the width of which is that of the stator, each sheet comprising successively along the axis (8) of the strip : - a rectangular projection (7), - a rotor bore, - a window (10, 12, 13) which is such that the base of the sheet has the shape of an inverted "U" adapted to contain an excitation coil (6) formed of a core (5) and a winding, the rectangular projection (7) originating from punching within a low portion of the window (10, 12, 13) of the sheet preceding in the strip, characterized in that the core is formed by a pile of sheets in the form of a rod (5), each sheet of the rod (5) originating from a second, high punching (10) of the sheet window, the rod (5) being located in the low portion of the window, and in that the sum of the height (9) of the projection (7) and of the height (10) of the rod (5) being equal to the depth of the hollow of the "U" of the sheet base in such a manner that no loss of material occurs in the longitudinal direction of the sheet strip (14). |
