Claim 0:
1. 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 an implantation diameter of the cylindrical magnetic mass in order 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 each insertion hole comprising an internal thread, a plug being screwed into the internal thread so as to close the free end of the attachment flange,
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.
