Patent ID: 8610322

Claim:
A method for operating a magnetic bearing that contains a ferromagnetic, movably supported bearing element ( 1 ) and at least two magnetic devices ( 3 o , 3 u ) disposed on opposite sides of the bearing element ( 1 ) and equipped with windings ( 6 ), wherein during operation of the magnetic bearing, electric currents are conducted through the windings ( 6 ) and these currents are regulated such that in an equilibrium state between the bearing element ( 1 ) and the two magnetic devices ( 3 o , 3 u ), bearing gaps ( 10 o , 10 u ) of preselected size (So, Su) form, characterized in that the temperatures produced in the magnetic devices ( 3 o , 3 u ) during operation are measured and the currents are regulated such that in the equilibrium state, regardless of the load situation, the same temperatures develop in the magnetic devices ( 3 o , 3 u ) or in the windings ( 6 ) thereof.
