A method for manufacturing a rotor for electric motors is described, said method comprising the steps of: providing a central core with a predetermined cross-section; providing a plurality of ferromagnetic discs having a hole shaped in a complementary manner to the cross-section of the central core; stacking up said ferromagnetic discs around said central core, thus forming a cylindrical structure with a longitudinal cavity wherein said longitudinal cavity is formed by said holes of the stacked-up ferromagnetic discs; integrally locking together said stacked-up discs; and removing the central core. |
