Reluctance - motor / - generator is excited by a winding in the air gap.

摘要

The invention concerns a machine forming a motor or generator comprising a stator and a rotor, characterised in that the rotor (6) is a passive rotor, consisting of two ferromagnetic discs whereof at least one is toothed, and the stator comprises a fixed polyphase (P1, P2, P3) field coil (13) arranged in an air gap defined by the space (12) provided between the two discs (8, 9) and generating a rotating magnetic field, and a field coil (14) likewise fixed. The invention is likewise applicable to a cylindrical rotary machine or to a machine with linear displacement.
