Abstract
A flux concerning electrical machine has a stator and a rotor, the stator including on its face a series of notches housing a series of stator coils, and further including a series of housings for excitation means, and the rotor including a plurality of flux commutator teeth for selectively making pairs of closed magnetic circuits through the stator coils. In accordance with invention the stator includes a plurality of independent stator coils defining as many phases and located in a series of individual cells angularly distributed on its circumference and the rotor teeth are equi-angularly spaced so that the angular positions of the various pairs of teeth have predetermined phases relative to the various individual cells. The invention is applicable in particular to brushless alternators for motor vehicles.
