Electric machine having an axial electrodynamic bearing

The invention relates to an electric machine extending along an axis Z, and comprising (i) a rotor portion configured for rotating around the Z axis at a defined position along the Z axis, and comprising a field source having p pole pairs; (ii) a stator portion comprising at least one pair of windings comprising each an upper (30) and a lower (40) winding, comprising each a plurality of p pole pairs, the upper (30) and lower (40) winding being arranged so as to form a passive axial electrodynamic bearing. According to the invention, the connections (31-42, 32-41 or 31-41,32-42) between the upper (30) and lower (40) windings comprise terminals of the electric machine connectable to an electric power supply or to an electric load.
