摘要： The invention concerns a rotating electric machine comprising a stator (10) equipped with armature coils (18) and a rotor (20) mounted rotating inside the stator, the rotor having a series of magnets (22N, 22S) with alternating polarities juxtaposed with magnetic parts having magnetic resistance (24a, 24b) respectively associated with said magnets, each assembly of one magnet and one associated magnetic part defining a rotor pole (PP). The invention is characterised in that at least some of said poles have alternately, along a generally tangential direction, a magnet (22S) followed by its magnetic part (24a) and a magnet (22N) preceded by its magnetic part (24b). The invention is particularly applicable to motor vehicle alternators and AC starters.

摘要： The invention concerns an electric machine comprising a stator (1) and a rotor (2), the stator including at least a stator coil (14) housed in at least a couple of slots (13), the rotor including at least two successive excitation magnets which in the rotor generate two magnetic fluxes having, tangentially along the rotor structure, components of opposite directions, said rotor having between said two magnets an even number of slots defining between them two projecting poles wherein are received winding strands capable of being powered to define alternate poles with the magnets. The invention is characterised in that each of the slots (23) receiving winding strands (26) is occupied by only one strand or several strands wound around the same projecting pole and the rotor shaft (A) is made of a magnetic material, said machine comprising in the proximity of said shaft (A) and magnets (27) at least a non-magnetic zone (28, 28a; 30) which reduces to a minimum or cancels the leakage flux towards the rotor shaft.
