Abstract (en)
[origin: WO2021176058A1] The invention relates to a rotor (100) for an axial flux electromagnetic machine, comprising a body (110) in the overall shape of a disc, with a peripheral edge having at least one slot (120) delimited by at least two edges (121), and at least one permanent magnet (130) which is situated in said slot and which has at least two edges (131) facing the at least two edges of the slot. According to the invention, one of the edges of the slot extends longitudinally along a mean line (D1) and has a cross section, at this mean line, the shape of which varies along the mean line so as to form at least one first relief (140), and a part of one of the edges of the permanent magnet has at least one second relief (141) of corresponding shape, in negative, so as to conform to the shape of said at least one first relief.
