Abstract
The invention relates to a magnetic bearing and to a method for operation thereof. The magnetic bearing contains a ferromagnetic, movably mounted bearing element () and at least two magnetic devices () arranged on opposing sides of the bearing element () and equipped with windings (), wherein during operation of the magnetic bearing, electric currents are conducted through the windings () and these currents are regulated such that in an equilibrium state between the bearing element () and the two magnetic devices (), bearing gaps () of predetermined size (So, Su) form. According to the invention, the temperatures produced in the magnetic devices () during operation are measured and the regulation of the currents takes place such that in the equilibrium state, regardless of the load situation, the same temperatures appear in the magnetic devices () or in the windings () thereof (FIG.).
