Abstract
The invention concerns a machine forming a motor or generator including a stator and a rotor. The rotor is a passive rotor, consisting of two ferromagnetic discs whereof at least one is toothed. The stator includes a fixed polyphase field coil arranged in an air gap defined by the space provided between the two discs and generating a rotating magnetic field, and a field coil likewise fixed. The invention is applicable to a cylindrical rotary machine or to a machine with linear displacement.
