Zusammenfassung:The invention relates to a rotor with claw-shaped poles for a rotary electric machine. The rotor includes a plurality of interpolar magnetic assemblies. In a radial cross-sectional plane, a first total surface of a magnet of a section of the magnetic assembly is smaller than a second surface defined by the product between the radial height of a surface (h) of the magnetic assembly (40), oriented towards the polar claw (44a), and the circumferential distance between the polar claws (44a, 44b) in the interpolar gap. The magnet is provided with at least one recess extending in an axial direction.
