Claim 18:
19. A rotor with a non-through shaft for a rotary electric machine, comprising
a cylindrical magnetic mass clamped between two half-shafts each comprising an attachment flange connected to the cylindrical magnetic mass,
axial housings being uniformly provided in the cylindrical magnetic mass on at least one diameter of the cylindrical magnetic mass to house conductive bars,
at least one attachment flange comprising insertion holes each disposed facing an axial housing of the plurality of axial housings for inserting the conductive bars into the axial housings with the exterior diameter of the attachment flange being substantially equal to the exterior diameter of the cylindrical magnetic mass, the attachment flange including as many insertion holes as the axial housings, and the attachment flange comprising a chamfer on its face opposite to the cylindrical magnetic mass and extending from the outer periphery of the attachment flange so as to cover the insertion holes,
two short-circuit discs each interposed between one of the attachment flanges of the half-shafts and one of the ends of the cylindrical magnetic mass, and
conductive bars inserted into the axial housings so that the conductive bars and the short-circuit discs form a squirrel cage.
