Abstract:
1. A synchronous electric machine (M), comprising an armature (A) and an inductor (B) between which is defined an air gap (G); the armature (A) having at least one pair of poles (N, S); the inductor (B) having, for each pair of poles (N, S) of the armature (A), n identical ferromagnetic tooth structures ( the surface of the armature (A) facing the air gap (G) is divided into 2N elements or samples ( each of the said ferromagnetic tooth structures of the inductor having at the air gap a sequence of teeth ( each sample ( each sample ( the armature (A) includes a plurality of magnetically distinct bodies ( the magnetic potentials (τ in which the inductor (B) is formed in such a way that it is able to generate a magnetomotive force distribution which is seen by the armature (A) identically in all relative positions which are separated from one another by one slot pitch (P), and in which in the 2N/n possible alignment conditions for each sample (
