Claim:
1. A method for controlling an operation of a multi-phase electric machine with a stator and a rotor, wherein the stator or the rotor comprises permanent magnets, wherein the rotor or the stator comprises a plurality of conductor bars interconnected by connecting elements of at least one circuit board and disposed within a magnetic field of the permanent magnets and having an internal inductance connected, wherein the connecting elements are arranged outside the magnetic field and have an external inductance, wherein each phase includes at least one of the conductor bars, wherein the electric machine is controlled by regulating for each phase of the multi-phase electric machine at least one electrical quantity, which is dependent on the internal and external inductance of a respective phase, to a desired value determined in dependence on at least one mechanical operating parameter of the electric machine to provide the desired value of the at least one electrical quantity for each phase, wherein the at least one electrical quantity is a voltage, wherein an actual value of the at least one electrical quantity of the respective phase is tapped between the conductor bars and the connecting elements of the respective phase.
