A turbomachine (10) comprises a turbine shaft (42), first (36) and second (40) rotors, first (12) and second (14) propulsion stages, and a magnetic stator (38). The first rotor (36) is rotationally coupled to the turbine shaft (42), and coaxially arranged along an axis (C L ). The first propulsion stage (12) is rotationally coupled to the first rotor (36), opposite the turbine shaft (42). The second rotor (40) is coaxially arranged about the first rotor (36), and the second propulsion stage (14) is rotationally coupled to second rotor (40), opposite the turbine shaft (42) and adjacent the first propulsion stage (12). The magnetic stator (38) is coaxially arranged between the first rotor (36) and the second rotor (40), forming a magnetic coupling between the first (36) and second (40) rotors to drive the second propulsion stage (14) in contra-rotation with respect to the first propulsion stage (12).
