Method for converting wind energy into electrical energy, in which, in a first phase (25) of an operating cycle, a kite (14) is used to exert a tractive force upon a traction-cable winch (16), and the tractive force is converted into a driving force for an electrical machine (17), such that the electrical machine (17) generates electrical energy, and in which, in a second phase (26) of the operating cycle, the electrical machine (17) is used to drive the traction-cable winch (16) to reel-in the traction cable (15). The electrical machine (17) comprises a first rotor (29), a second rotor (30) that interacts electrically with the first rotor (29), and an axial portion in which the magnetic components of the first rotor (29) overlap with the magnetic components of the second rotor (30). The first rotor (29) is mechanically coupled to the traction-cable winch (16). In the second phase (26) of the operating cycle, kinetic energy of the second rotor (30) is used to drive the traction-cable winch (16). The invention also relates to a corresponding device.
