Abstract An electrical machine (20) coupled to a compressor (12) having a rotatable shaft (16), comprising: a rotor forming part of the rotatable shaft and having at least two magnetic portions (22A, 22B) separated by an inclined non-magnetic portion (24) and two elements (26A, 26B) of non-magnetic material at each end of the rotatable shaft, a stator comprising a laminate magnetic iron stack (28) surrounded by a winding (30) and disposed along a periphery of the rotor to define a first annular gap (32), a ring (34) of non-magnetic material disposed around the stator, a DC coil (38) disposed around the non-magnetic ring, and a casing (40) of magnetic material disposed around the DC coil and having radial walls (40A, 40B) that project inwardly towards the rotor by defining a second annular gap (42) therebetween. Une machine électrique (20) couplée à un compresseur (12) muni dun arbre rotatif (16), laquelle comprend un rotor formant une partie de larbre rotatif et comportant au moins deux parties magnétiques (22A, 22B) séparées par une partie non magnétique inclinée (24) et deux éléments (26A, 26B) composés dun matériau non magnétique à chaque extrémité de larbre rotatif. La machine comprend également un stator comprenant une pile de fer magnétique stratifié (28) entourée dun enroulement (30) et disposée le long dune périphérie du rotor pour définir un premier espace annulaire (32), un anneau (34) composé dun matériau non magnétique disposé autour du stator, une bobine à courant continu (38) disposée autour de lanneau non magnétique et un boîtier (40) composé dun matériau magnétique disposé autour de la bobine à courant continu et ayant des parois radiales (40A, 40B) qui font saillie vers lintérieur en direction du rotor en définissant un second espace annulaire (42) entre les elles.
