The disclosure concerns a method for operating a wind turbine having a generator, the generator having for each phase a plurality of coils, wherein the plurality of coils of each phase includes at least one group of coils including at least two coils, the group of coils including at least two subgroups including at least one coil, wherein the generator has a first state in which the coils of the group of coils are electrically connected in series, and, the generator has a second state in which the at least two subgroups are switched electrically in parallel; the method including: changing the state of the generator. Further, the disclosure concerns a coil arrangement for an electric machine for a wind turbine, the electrical machine having for each phase a plurality of coils, wherein the plurality of coils of each phase includes at least one group of coils including at least two coils, the group of coils including at least two subgroups including at least one coil, wherein the electrical machine has a first state in which the coils of the group of coils are electrically connected in series, and, the electrical machine has a second state in which the at least two subgroups are switched electrically in parallel.
