Abstract
Spřádací rotor pro uložení v elektromagnetickém ložiskovém a hnacím systému obsahuje oboustranně otevřenou spřádací misku (1), která je uložena na jednom konci dutého nosného tělesa (2), na jehož obvodu je uložen feromagnetický prstenec (5) pro funkci magnetického ložiska a v jehož dutině je uložen prstencový permanentní magnet (3) vícepólově zmagnetovaný nebo složený z několika segmentů pro funkci elektrického pohonu. Nosné těleso (2) je z feromagnetického materiálu a je na konci, v němž je uložena spřádací miska (1) opatřeno vnějším obvodovým lemem (21), vedle něhož je na vnějším obvodu nosného tělesa (2) uložen neferomagnetický prstenec (4), vedle kterého je na vnějším obvodu nosného tělesa (2) uložen feromagnetický prstenec (5). Nosné těleso (2) se před montáží permanentního magnetu (3) předehřeje a permanentní magnet (3) se ochladí, čímž se po vložení permanentního magnetu (3) do nosného tělesa a vyrovnání teplot s okolím dosáhne mechanického předpětí mezi nosným tělesem (2) a permanentním magnetem (3).The spinning rotor for housing in the electromagnetic bearing and drive system comprises a spinning cup (1) which is open on both sides and which is supported on one end of the hollow support body (2), on whose circumference a ferromagnetic ring (5) is provided for the function of the magnetic bearing and in the cavity of which there is an annular permanent magnet (3) multi-pole magnetized or composed of several segments for the electric drive function. The support body (2) is of ferromagnetic material and is provided at the end in which the spinning cup (1) is provided with an outer peripheral rim (21) next to which a non-ferromagnetic ring (4) is placed on the outer periphery of the support body (2). in which a ferromagnetic ring (5) is mounted on the outer periphery of the support body (2). The support body (2) is preheated before the permanent magnet (3) is mounted and the permanent magnet (3) is cooled, whereby a mechanical bias between the support body (2) and the mechanical magnet (3) is obtained after inserting the permanent magnet (3) into the support body and permanent magnet (3).
