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.

本发明涉及旋转电机的转子，该转子包括转子本体(2)，在转子本体中以使得限定转子的磁极(4)的方式设置有凹部(3)，特别是每个磁极具有至少三个凹部，每个磁极具有磁极的径向轴线，凹部(3)具有细长形状并且各自包括两个短边，凹部被设置在针对每个磁极而言的一排或多排中，一排包括连续地设置的至少两个或甚至至少三个凹部(3)，凹部的短边在给定排的两个连续的凹部之间限定材料桥状部，所述材料桥状部大体上沿着桥状部的纵向轴线(2)延伸，越远离旋转轴线，桥状部的纵向轴线越靠近转子的对应磁极的径向轴线定向。
