Abstract

The present invention concerns an electric generator as component of an electric drive at variable speed, able to deliver electric power to a three-phases power grid. The generator comprises essentially a stator winding whose core is allocated on the generator case, a rotor winding, whose core is assembled to the generator shaft. On this shaft a slip rings collector is mounted, supported and rotating inside the case. An hollow ferromagnetic cylindrical core presents slots in which bar conductors are arranged. This cylindrical core is a rigid element and free to turn between the stator and the rotor by means of revolving bearings disposed on the same generator shaft or in the case.
