A synchronous rotating electrical machine is disclosed, of the type including a stator (10) and a rotor (11). The rotor is of the flux concentration type and includes a plurality of alternate North and South poles formed from permanent magnets (PM). The magnets are housed in slots (E1) arranged in the magnetic body of the rotor. Each pole comprises a second slot (E3) roughly radial and arranged in the magnetic body of the pole, between two consecutive magnets delimiting the pole. In accordance with the invention, each pole includes a portion forming a bridge (BR) between the magnetic bodies of the rotor, on either side of the second slot, this part forming a bridge including a magnetic body height not greater than approximately one times the dimensional value of the width of the permanent magnets. |
