Abrégé
(EN)

The present invention concerns a rotor of a rotating electric machine, comprising a rotor body (2) in which recesses (3) are provided in such a way as to define the poles (4) of the rotor, in particular at least three recesses per pole, each pole having a radial axis of the pole, the recesses (3) having an elongated shape and each comprising two short sides, the recesses being disposed in one or a plurality of rows per pole, one row comprising at least two, or indeed at least three recesses (3) disposed consecutively, the short sides thereof defining, between two consecutive recesses of a given row, a material bridge, said material bridge generally extending along a longitudinal axis (2) of the bridge oriented closer to the radial axis of the corresponding pole of the rotor, the further one is from the rotational axis.
