Abstract: A method for controlling an electric machine using measurement coils arranged in an air gap situated between a stator and a rotor of the electric machine, a plurality of phase windings assigned to different electrical phases being present. Magnetic linkage fluxes are measured in the air gap via the measurement coils, Magnetic linkage fluxes are determined of the plurality of phase windings of the different phases. The determined magnetic linkage fluxes are transformed into a stator-fixed orthogonal coordinate system in order to obtain orthogonal magnetic linkage fluxes. Phase currents flowing through the plurality of phase windings are measured. The measured phase currents are transformed into the stator-fixed orthogonal coordinate system in order to obtain orthogonal phase currents. An instantaneous torque and/or a flux-forming component of a phase current vector are ascertained. The electric machine is controlled based on the instantaneous torque and/or the flux-forming component.
