Abstract
An axial bearing device includes an annular electrical sheet arrangement having individual sheets which protrude radially outward. In addition, an electrical coil is provided in the axial bearing device and is inserted into the electrical sheet arrangement to generate a magnetic field in the electrical sheet arrangement. The electric sheet arrangement includes at least two concentric electrical sheet rings. All adjacent electrical sheets of each electrical sheet ring substantially abut at the inner circumference of the respective electrical sheet ring.
Claims14
A magnetic axial bearing device, comprising:
- an annular electrical sheet arrangement having individual sheets which protrude radially outward, with adjacent sheets forming a gap in a circumferential direction, said electrical sheet arrangement having at least two concentric electrical sheet rings, with essentially all the adjacent sheets of each electrical sheet ring meeting at the inner circumference of the electrical sheet ring;
- and
- an electrical coil inserted into the electrical sheet arrangement for producing a magnetic field in the electrical sheet arrangement,
- wherein the electrical sheet arrangement has at least three concentric electrical sheet rings, with an outer one, an inner one, and at least one middle one, wherein the at least one middle one of the electrical sheet rings having a depression for insertion of the electrical coil, wherein the depression runs through at least one of the inner sheet ring or the at least one middle sheet ring.
