Abstract
This invention relates to a rotor (1) with semi-embedded magnets for an axial flux motor or generator, comprising a body (2) in the form of a disc with two circular faces, the disc having an inner and an outer periphery which delimit a recess for a rotating shaft (7), at least two permanent magnets (2a) being applied against at least one of the two circular faces of the body (2) being held on said face by holding means (3a, 5, 5a, 6, 6a), with a gap between the at least two magnets (2a). The holding means (3, 3a, 5, 5a, 6, 6a) are in the form of at least one lateral, axial holding means (3, 3a) housed in the gap comprising at least one tenon (3a) locally covering at least one of the two magnets (2a) or an axial holding means (5a, 6a) forming a ring.
