    Abstract: An electromagnetic bearing including a stator portion having sixteen magnetic cores facing the rotor portion. The sixteen cores are divided into four groups of four cores, and each group is equipped with suspension electric windings disposed such that the magnetic flux produced thereby is in the same direction in the first two cores of the group and in the opposite direction in the following two cores, each core in each group further being equipped with a position-detection electric coil, the coils on the four cores in any one group being connected together in series and powered by an AC electric current, the magnetic flux produced by the coils at any determined time being in opposite directions in the first two cores of any group, and also in opposite directions in the following two cores.
