Abstract: The present invention is a variable air gap in a rotary electric machine, notably a permanent magnet-assisted synchronous reluctance electric machine.

Abstract: The present invention relates to a combustion chamber (10) of a turbine, in particular a turbine with a thermodynamic cycle comprising a recuperator, for producing energy, in particular electrical energy, comprising a casing (12) with an injection means (52) for injecting at least one fuel, and a hot compressed air intake (32), said casing housing a flame tube (22) with a perforated diffuser (26) for the passage of the hot compressed air and the fuel, and a flame stabiliser (54). According to the invention, the chamber comprises an air deflector (36) arranged facing the hot compressed air intake (32) in order to circulate this hot air in a single axial direction from this intake.

Abstract: The present invention relates to a rotor (1) for an electrical machine having N primary magnetic poles (13) and N secondary magnetic poles (14). the poles are flux barriers having opening angles (?1, ?2, ?3) for the poles to be asymmetrical. The invention further relates to an electrical machine comprising such a rotor.

Abstract: The present invention relates to a rotor (1) for an electric machine consisting of N primary magnetic poles (13) and N secondary magnetic poles (14), said poles consisting themselves of flux barriers (9, 10, 11) separated from axial housings (6) by magnetic bridges (19, 20, 21). According to the invention, on either side of axial housings (6), magnetic bridges (19, 20, 21) are aligned in a straight line, forming an angle ?1 for primary magnetic poles (13) and an angle ?2 for secondary magnetic poles (14) with respect to a radial direction, in such a way that ?2=?1+1±0.5. The invention further relates to an electric machine comprising such a rotor.

Abstract: The present invention relates to a compression device driven by an electric machine, for which the rotor (1) comprises a rotor shaft (31), a cylindrical magnet (34), and a non-magnetic shrink ring (33). According to the invention, the rotor shaft (31) includes a bore (36) for inserting one end of the compressor shaft (3) to unitize the two shafts.

Abstract: A combustion chamber (18) of a thermodynamic cycle turbine with a recuperator, for electrical energy production, comprising a casing (56) housing a flame tube (64) with a perforated diffuser for passage of the hot compressed air, a primary zone (ZP) that receives part of the hot compressed air flow and where combustion takes place, and a dilution zone (ZD) where the burnt gases from the primary zone mix with the remaining part of the hot compressed air flow, said chamber further comprising an injection means (76) for injecting at least one fuel. The flame tube carries a flame stabilizer (82) comprising perforated diffuser (88), at least one combustion gas recirculation passage (98) and a mixing tube (94).
