The aim of this research project is the study of a novel ring-twisting element system on the basis of a superconducting magnetic bearing (SMB) for textile machines, through theoretical modeling, simulation and metrological investigation of this novel combination of textile and superconductor technology under dynamic yarn path.In the first project phase, the theoretical and experimental basis for the introduction of a SMB twisting element system in the ring spinning machine have been developed, which allow a trouble-free spinning process up to 25,000 rpm. The interactions of process, technology and superconducting parameters were evaluated and laws for the SMB twisting element system were derived. The second funding phase will explore the SMB twisting element with regard to the yarn dynamics, nonlinear fiber expansion behavior and the vibration behavior of the SML and the yarn at higher spindle speeds up to 50,000 rpm. With the completion of this project, as a central objective, the scientific basis for the use of superconducting magnetic bearings in high-speed textile and processing machines is available.
