Arrangement for non-contact revolution counting of an open-end spinning rotor |
摘要 |
The spinning rotors of open-end spinning aggregates are supported on supporting discs. For the purposes of non-contact revolution counting, a front side of a supporting disc is provided with at least one permanent magnet. A signal receiver of a maintenance device selectively arrangeable at the spinning aggregates is arranged at the permanent magnet. The distance between the permanent magnet and the signal receiver is bridged by a ferromagnetic information transmitter, which is preferably arranged on a swivelling housing section of the spinning aggregate.
