Abstract
An electrical machine includes a stator and a rotor. The stator includes on its internal face at least one induction winding housed in a pair of recesses and a series of housings for excitation means. The rotor does not have windings and includes teeth for establishing variable magnetic fluxes in the induction winding. The excitation brings into play permanent magnets adapted to establish a closed circumferential magnetic flux in the stator and excitation windings locally establishing an adjustable magnetic flux in the reverse circumferential direction. The rotor teeth are adapted to effect a flux commutation in the stator and the, or each, permanent magnet occupies an angular position located between the angular positions of the two arms of a common induction winding. In this way an alternating magnetic flux is produced in the induction winding or windings during the rotation of the rotor.
