ABSTRACT:
An alternator of the single-phase type in particular is composed of an armature (1) provided with at least one winding (2) and an inductor (3) comprising on the one hand a magnetic circuit (4) having at least one pair of poles (5) with lateral pole shoes (6) and on the other hand at least one excitation winding (2) formed around said magnetic circuit (4), the inductor (3) and armature (1) being rotatable with respect to each other. At least one pole (5) is provided in the vicinity of at least one pole shoe (6) with a slot (9) occupied by a corrector winding (8) which embraces the pole shoe (6) and is connected electrically so as to permit the flow of substantially direct current through the corrector winding during service.
