Abstract:
1. A turbomachine arranged with a rotor and a stator, the turbomachine comprising: a fluid-flow portion enabling energy to be exchanged between a fluid passing therethrough and the rotor, including at least one bladed wheel mounted on a shaft of the rotor; an electrical portion suitable for converting electricity into work or vice versa; radial positioning device configured to position the rotor radially; and a contactless axial balancing device arranged on said bladed wheel, providing axial balancing for the rotor at high speed; wherein: the turbomachine further comprises a thrust bearing distinct from the radial positioning device, which thrust bearing provides axial balancing of the rotor at low speed, and is contactless at high speed; and the radial positioning device is constituted solely by hydrostatic bearings to comprise the sole radial positioning device, the turbomachine including hydrostatic bearing feed circuits suitable for connecting said bearings to a source of fluid under pressure.
