1. An electrical multiphase machine with a stator (3) which includes a winding (5;

  • 6) having at least two strands (51, 52, 53;

    61, 62) for generating an electromagnetic field, each strand (51, 52, 53;

    61, 62) belonging to a different electrical phase;

    furthermore with a setting device (4) which supplies each strand (51, 52, 53;

    61, 62) with a phase current (Ia, Ib, Ic) or phase voltage (Ua, Ub, Uc) in each case as a setting parameter, said setting device (4) including a separate power amplifier (41a, 41b, 41c, 41d) for each strand (51, 52, 53;

    61, 62), so that the setting parameter can be regulated for each strand (51, 52, 53;

    61, 62) independently of the setting parameters for the other strands (51, 52, 53;

    61, 62) and at least one common connection point (VP) being provided to which at least two of said strands (51, 52, 53;

    61, 62) are connected, characterized in that an additional active control element (44) is provided for shifting the potential of said connection point (VP).
