Abstract:
1. An electromechanical converter comprising: a primary shaft having a rotor mounted thereon; a secondary shaft having an interrotor mounted thereon; and a stator fixedly mounted to a housing of the electromechanical converter, wherein, viewed from the primary shaft in a radial direction, the rotor, the interrotor, and the stator are arranged concentrically relative to each other, and wherein the rotor and the stator comprise one or more windings, and wherein the interrotor comprises one whole both mechanically and electromagnetically, and the interrotor further comprises a magnetic and an electric circuit, the magnetic circuit including a magnetic flux conducting cylinder and the electric circuit including a number of electric circuit-forming windings extending in the flux conducting cylinder, and wherein the interrotor is arranged as a conductor for the magnetic flux in a tangential and a radial direction so that exertion of a direct torque between rotor and stator can occur upon magnetic saturation of the interrotor.
