Abstract:
An electrical machine comprising:a stator including on an internal face at least one induction winding housed in a pair of recesses and a series of housings for excitation means;a rotor without windings and including a plurality of teeth adapted to selectively establish variable magnetic fluxes in the induction windings, the teeth of the rotor being adapted to effect a flux commutation in the stator; andsaid excitation means including at least one permanent magnet adapted to establish a magnetic flux in a circumferential direction of the stator and at least one excitation winding adapted to that of the flux produced by said permanent magnet, said permanent magnet occupying an angular position located between angular positions of two arms of a common induction winding of said at least one induction winding so as to produce an alternating magnetic flux in the induction winding during rotation of the rotor.
