Patent ID: 8212444

Claim:
A bearing arrangement comprising: a rotor component ( 16 ) including a shaft ( 14 ), a stator component ( 10 ) including a bearing bush ( 12 ), a fluid dynamic radial bearing ( 18 a , 18 b ) for rotatably supporting the shaft ( 14 ) about a rotational axis ( 20 ; 120 ) with respect to the bearing bush ( 12 ), a magnetic axial bearing ( 22 ) for taking up axial forces that act on the rotor component the magnetic axial bearing comprising: a first bearing part ( 24 ; 50 ; 124 ) comprising at least one permanent magnet ( 26 ; 126 ) and at least two flux guide elements ( 28 ; 128 ) associated with the permanent magnet ( 26 ; 126 ) that are disposed on opposing end faces of the permanent magnet and aligned substantially radial and perpendicular to the rotational axis, a second bearing part ( 30 ) comprising at least two flux guide elements ( 32 ; 132 ) that are disposed at a mutual spacing to one another and aligned substantially radial and perpendicular to the rotational axis, each flux guide element ( 32 ; 132 ) of the second bearing part ( 30 ) being associated with a flux guide element ( 28 ; 128 ) of the first bearing part ( 22 ) and lying directly opposite the latter in a radial direction and separated from it by an air gap ( 34 ), wherein the flux guide elements of one or both bearing parts narrow in cross section where they lie opposite of the respective flux guide element on the other bearing part in order to focus the magnetic flux that is generated by the permanent magnet.
