Rotating electric machine rotor configuration of permanent magnets OPTIMIZED

The invention focuses on a rotor (10) for a rotary electric machine comprising: - a rotor body (11), particularly formed by a stack of laminations, and - a set of permanent magnets (22), characterized in that a ratio between a greatest thickness (L3) of a permanent magnet (22) of the permanent magnet assembly (22) measured in a radial direction and the greatest width of said magnet (22) of the assembly permanent magnets (22) measured along a orthoradial direction is at least equal to 30%.
