A rotating electrical machine including a rotor (2), the magnetic circuit of which carries excitation members, and a stator (16), the magnetic circuit of which carries a stator coil. The magnetic circuit of the rotor includes a shaft (1) on which are mounted end flanges (3) and at least one toothed disk (4) disposed between the end flanges, the teeth of the toothed disk being regularly spaced at its periphery, and at least one annular member (9) mounted on the end flanges and having slots (10) regularly distributed at its periphery and in each of which is engaged one tooth of at least one toothed disk. The end flanges and the toothed disk are spaced apart by gaps in which excitation members (14, 15) are accommodated.
