Abstract
A method is provided for identifying a spinning rotor on a rotor spinning machine, wherein the spinning rotor is mounted in a suspended manner in a radially acting magnetic bearing during a spinning operation. At least one system variable that varies between different spinning rotors is identified. The system variable is detected and compared to at least one reference value. The system variable is one or a combination of: an energy consumption of the magnetic bearing; a radial position of the spinning rotor; or a resonant frequency of the spinning rotor. A rotor spinning machine that carries out the method is also provided.
