摘要： The invention relates to a method for correcting variations of parameters of components of active magnetic bearing and/or assembly of active magnetic bearing as a whole. At the latest before starting to operate the active magnetic bearing are detected mechanical and/or electrical and/or installation variations and/or other variations of parameters of at least one component of the active magnetic bearing and/or of the whole active magnetic bearing assembly, whereupon the detected variations and/or correction values based on the variations are recorded in memory (M), which is an integral part of the active magnetic bearing assembly, and subsequently these variations and/or correction values are used from the memory (M) for adjustment of system for detecting position of the rotating working means in the active magnetic bearing during operation of the active magnetic bearing. The invention further relates to an active magnetic bearing for bearing a rotating working means which comprises in the basic body placed means of creating a magnetic field, in which the rotating working means is arranged and which further comprises sensors of position of the rotating working means, whereby, with each said sensor of position are aligned detector of its output signal and evaluation circuits. In the active magnetic bearing assembly there is arranged a memory (M), in which are stored values of production and/or electrical and/or installation variations of at least one component of the active magnetic bearing and/or variations of the whole active magnetic bearing assembly and/or in the memory (M) are stored correction values formed from said variations, whereby the memory (M), the control system and/or the detectors (D) of the output signal of the sensors (A) of the position and/or the evaluation circuits are interconnected or interconnectable.

摘要： A spinning unit and method for detecting changes of position of a shaftless spinning rotor (1) of an open-end spinning machine in a cavity of an active magnetic bearing, in which the position of the spinning rotor (1) is detected by a system of sensors (A, B) and on basis of the detected changes in the position of the spinning rotor (1) is adjusted controlling of the active magnetic bearing in order to eliminate undesirable changes in the position of the spinning rotor (1) in the cavity of the active magnetic bearing. Continuously is detected radial shifting of the spinning rotor (1) and simultaneously is continuously detected inclination of the spinning rotor (1), whereupon according to the detected changes in the position of the spinning rotor (1) is determined shifting and/or inclination of the spinning rotor (1) which is used for subsequent adjustment of the controlling of position of the spinning rotor (1) in the active magnetic bearing, wherein both radial shifting and inclination of the spinning rotor are each detected by at least two pairs of sensors of the distance of monitored surface of the spinning rotor, the pairs of sensors for detecting radial shifting of the spinning rotor detect changes of distances of the cylindrical wall of the spinning rotor from the sensors. The sensors (A, B) of the position of the spinning rotor (1) are grouped into pairs, whereby two pairs of sensors (A1, A2) for detecting of radial shifting of the spinning rotor (1) are arranged on the opposite sides of the spinning rotor (1) against the cylindrical wall (10) of the spinning rotor (1) and at the same time another two pairs of sensors (B1, B2) for detecting of inclination of the spinning rotor (1) are arranged on the opposite sides of the spinning rotor (1) against the wall (11) of the spinning rotor (1), which is perpendicular to the rotation axis (OA) of the spinning rotor (1).
