Abstract This invention is concerned with synchronous electric machines. The synchronous electric machine of the present invention comprises an excitation winding, a rectifier energizing said excitation winding, and a three-phase armature winding with at least two circuits in each phase being wound with different pitches. Therewith, the like terminals of each phase''s circuits are interconnected to form the terminal of a respective phase of the machine, the free terminals of the circuits of all the phases with one winding pitch being interconnected to form a neutral point and the free terminals of the circuits of all the phases with the other winding pitch being interconnected to form another neutral point with said rectifier being connected to said neutral points.
