Abstract
Various teachings of the present disclosure include a method for operating an electric motor of rotor-stator-rotor configuration and a first gap with a first thickness d1 between a first rotor and a stator and a second gap with a second thickness d2 between the stator and a second rotor, wherein the first rotor and the second rotor are electrically excitable separately from each other. An example includes: detecting a first open-circuit voltage of the first rotor; detecting a second open-circuit voltage of the second rotor; classifying the first open-circuit voltage and the second open-circuit voltage; and adjusting the electrical excitation of at least one from amongst the first rotor and the second rotor based on at least one of the classified open-circuit voltages.
