Abstract (en)
[origin: CN111945260A] The invention relates to a method for detecting a spinning rotor (5) on an open-end spinning machine (1), in which the spinning rotor (5) is mounted in a floating manner in an at least radially actingmagnetic bearing (6) and rotates in the bearing (6) during spinning operation, and in which at least one variable system variable is compared with at least one reference value. It is proposed that the at least one variable system variable is the energy absorption of the support (6), the radial position of the spinning rotor (5) and/or the resonance frequency of the spinning rotor (5). The invention also relates to the rotor spinning machine (1) for carrying out the method.
