The electric machine (1) has stator (2) and rotor (3). The electromotive force between stator and rotor is corresponded with respect to magnetic base flow. The magnetic base flow in stator is radial tangential oriented to rotational axis (4). Several throttles (7) are arranged tangentially to rotational axis, to produce magnetic additional flow (B') acted upon by respective choke current (I') in stator. The region (8) of stator is oriented to rotational axis so that electromotive force between stator and rotor is not affected by magnetic additional flow. |
