<p>The machine ( 1 ) comprises: a rotor ( 2 ) with a permanent magnet ( 5 ), for producing an annular distribution of magnetic polarities (N, S) of angularly alternating sign about the axis of rotation (A-A) of the rotor ( 2 ), within a magnetized surface ( 5 ) lying in a plane essentially perpendicular to said axis (A-A), and a stator ( 3 ) including: a flow-conveying structure ( 16 ) formed as one piece with a pressure-shaped mass of insulated ferromagnetic particles; this structure ( 16 ) having an annular base portion ( 17 ) from which first and second arms ( 18; 19 ) extend substantially parallel to the axis of the rotor (A-A), said arms being situated at a first and a second radial distance, respectively, from this axis (A-A) and angularly alternating with respect to each other; the ends ( 18 a ; 19 a) of these first and second arms ( 18, 19 ) frontally facing said magnetized surface ( 5 a) of the rotor ( 5 ) from which they are separated by an air-gap ( 21 ); and a winding ( 23 ) arranged coaxially with the rotor ( 2 ), in an annular region lying between the first and second arms ( 18; 19 ) of the flow-conveying structure ( 16 ).</p> |
