Design and Analysis of a1-DOF magnetic bearing (English)
Abstract [sv]

SammanfattningEtt nytt magnetlager med ett aktivt reglersystem i en frihetsgrad, 1-DOF, utvecklas och analyseras.Lagret är ett konventionellt radial permanent magnetlager, PMB, med en integrerad spole föraxiell stabilitet med tillhörande reglersystem för en riktning.En förenklad 2,5D-modell härledds, och resultaten jämförs med FEM resultat, samt med resultatetfrån en 3D-analytisk metod.Resultaten visar på god överensstämmelse och avvikelser diskuteras.Steg svar för varierande belastning visar på att ett nytt jämviktsläge snabbt uppnås, där strömmenoch lagerförlusterna går mot noll.

Abstract [en]

AbstractA novel magnetic bearing with one actively controlled degree of freedom, 1-DOF, isanalyzed.The bearing is a conventional radial permanent magnetic bearing, PMB, with an integratedcoil for axial stability.A simplified 2,5D-model is derived, and results are compared to FEM-results, as well as a3D-analytical method.Results show good agreement, and the deviations are discussed.Step response to varying load shows that a new equilibrium position is quickly reached, wherethe current and bearing losses approaches zero.
