Title:Integrated Rotor Spinning Drive SystemAuthor(s):Siegfried Silber, Jiri Sloupensky, Milan Moravec, Martin Reisinger, Wolfgang AmrheinAbstract:This paper presents a novel drive and frictionless suspension system for a rotor spinning unit which opens the field for further textile technology development, possibly leading to higher productivity, less trash deposit and reduced power consumption. In contrast to conventional rotor spinning machines individually driven rotors are open on both sides allowing advanced arrangement of related spinning components. To achieve a very high lifetime the rotor is suspended by active magnetic bearing. Outstanding energy efficiency can be achieved by the frictionless suspension of the rotor and by a slotless electronically commutated permanent magnet motor in conjunction with an optimized frequency inverter.Booktitle:Mechatronics 2012, The 13th Mechatronics ForumPage Reference:5 page(s)Publishing:9/2012
