Abstract: The core inside a combined radial-axial magnetic bearing is stacked with coated laminations each equipped with at least one radial cut. These cuts prevent the inducement of circulating currents caused by varying axial control fluxes through the central hole of the stack. Magnetic symmetry is preserved by pivoting every lamination with respect to the previous one over a particular angle. This arrangement not only reduces the losses in the bearing, but improves the performance of the axial channel as well.
Abstract translation: 组合的径向轴向磁性轴承内的芯体与每个装备有至少一个径向切口的涂覆的叠片堆叠。 这些切割阻止了通过堆叠的中心孔改变轴向控制通量引起的循环电流的诱导。 通过在特定角度上相对于前一个层叠枢转每个层压来保持磁对称性。 这种布置不仅减少了轴承的损耗，而且提高了轴向通道的性能。

Abstract: The core of a combined radial -axial magnetic bearing is stacked with coated laminations each equipped with at least one radial cut ( 9 ). These cuts ( 9 ) prevent the induction of circulating currents caused by varying axial control fluxes through the central hole of the lamination stack. Magnetic symmetry is preserved by rotating every lamination with respect to the previous one.
