A rotor for an electric machine comprising a rotor core having a plurality of flux guide sections (FG1, FG2, FG3, FG4), each of the plurality of flux guide sections comprising: a plurality of flux paths (P1, P2, P3, P4) and a plurality of flux barriers (B1, B2, B3, B4); the rotor core comprising a plurality of bridges (BR11, BR12, BR12P) made of a material of high permeance, each of the plurality of bridges extending across a corresponding flux barrier. The rotor core further comprises a plurality of permanent magnets (M11, M12, M12P) each one of which is located adjacent a corresponding bridge (BR11, BR12, BR12P) and adapted to saturate the corresponding bridge, a magnetization direction (MD11, MD12, MD12P) of each of the plurality of permanent magnets diverging from the direction in which the corresponding bridge extends across the flux barrier. |
