    Abstract: The passive axial magnet bearing comprises permanent magnets (1, 2) arranged with alternating polarization on a rotor (1, 2, 8). These cause an oscillating flow through the coils (L) on both sides of the rotor (1, 2, 8). All coils (L) are series connected in an electric circuit (3). As long as the rotor (1, 2, 8) rotates in the middle position, no current flows in the electric circuit (3), since the voltages across the coils (L) cancel each other due to the symmetry. However, when the rotor (1, 2, 8) deviates from the center position, a current flows and the coils (L) exert electromagnetically a restoring force on the permanent magnets (1, 2). The bearing can also be equipped with an integrated drive. For this purpose, it is extended by drive coils. The production of the bearing is simple and inexpensive.
