Title:
LAMINATED CORE FOR A COMBINED RADIAL -AXIAL MAGNETIC BEARING AND CORRESPONDING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/054065
Kind Code:
A3
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.
