Abstract
A machine (1) having a rotor (11) including permanent magnets (PM) and field coils (EC). The magnets are housed in first axial recesses (E1) distributed within a circumferential portion of the magnetic body, thus defining circumferential polar sections. The coils are housed in second axial recesses (E2) distributed within an intermediate portion of the magnetic body and defining pole teeth (RT). The ratio of a width of a pole tooth to a height of a permanent magnet is around 0.65 to around 1.
