Abstract (en)
[origin: CN107893270A] The present invention relates to a method for operating an open-end rotor spinning device (1) with an exchangeable, single-motor driven spinning rotor (2). According to the invention, the spinning rotor (2) is accelerated from a first rotational speed (n1) to a second rotational speed (n2) and the acceleration time (tA, tB) required for the acceleration from the first rotational speed (n1) to thesecond rotational speed (n2) is detected and evaluated as an evaluation value or the spinning rotor (2) is accelerated by a first speed (n1) for a predetermined acceleration time (tA, tB) and the second speed (n2) reached in this time detected and evaluated as an evaluation variable. The invention further relates to the open-end rotor spinning device (1).
