The rotor (1) according to the invention includes a plurality of alternating north poles (N) and south poles (S) that are from a plurality of permanent magnets (3) arranged in first recesses (4). Said first recesses are evenly distributed about an axis (5) of the rotor and axially extend into a magnetic body (2) thereof, so as to define a predetermined number of circumferential pole sections (9). Said pole sections comprise second recesses (12), which are arranged between the permanent magnets and which axially extend into the magnetic body so as to define a plurality of magnetic bridges (14, 15), having a plurality of heights (htr1), in a circumferential portion (11) of the rotor. According to the invention, a first height (htr1) and a second height (htr2) of two of said consecutive magnetic bridges (14, 15) are different. |
