Abstract
The invention relates to a method for mounting permanent magnets in a rotor body and a method for manufacturing an axial flux electric machine rotor, the rotor body being made of non-magnetic material and comprising annular portions connected by radial portions (3), the radial portions (3) creating openings for positioning said permanent magnets (5), each radial portion (3) comprising an internal radial cavity (4). The following steps are carried out: a) the permanent magnets (5) are positioned in said openings and the concave surfaces (7) of the permanent magnets (5) are opposite the radial portions (3) at each circumferential end of each permanent magnet (5); b) the external surfaces of the radial portions (3) are deformed, these external surfaces fitting into the concave surfaces (7). The invention also relates to an electric machine rotor. Figure 2 to be published
