Abstract

A rotor (10) of an electric motor includes several poles (10) arranged circumferentially relative to the rotor, each pole comprising a first set (S1) proximate a rotor outer edge (32) and a second set (S2) farther from the latter. The first (S1) and second (S2) sets are symmetrical relative to a d-axis (A). Each symmetrical part (S2.1, S2.2) in the second set (S2) has two opposite ends (40, 44, 42, 46) terminating respectively with an outer flux barrier (40, 42) proximate the outer edge (32) and an opposite inner flux barrier (44, 46), both inner flux barriers (44, 46) being separated from each other by an arrangement comprising two radially-extending inner bridges (48, 50) flanking a central radially-extending flux barrier (52) aligned along the d-axis (A).
