Abstract
Disclosed is an asynchronous rotating electric machine in which none of the electrical windings is rotating, said machine having a homopolar compound structure. The machine comprises: a rotor including magnetic flux return parts; and a stator formed by a pair of armatures and a magnetic wedge connecting the armatures and providing the magnetic flux in the direction of the axis of rotation, an annular induction coil being supplied with alternating current and housed between the air gap and the wedge, and one or two armature coils being received by one or both of the armatures generating an alternating magnetic flux.
