Abstract: The invention relates to a device for the contactless transfer of electric power to a load arranged on a rotor 20 of an electric machine and for detecting the angular position of the rotor 20. The device comprises an inductive power transfer path for the inductive transfer of electric power to the electrical load and a resolver for detecting an angular position of the rotor 20, wherein the inductive power transfer path and the resolver use one magnetic circuit.
The invention furthermore relates to a corresponding method and to a corresponding electric machine.
