Preliminary studies are conducted at SEP to clarify the advantages and drawbacks of using S2M ACTIVE MAGNETIC BEARINGS (AMB) to suspend rotors of rocket engine turbopumps. After having pointed out their specific interest for rocket propulsion, technological keys for development will be presented. These latter are found among the following subjects: AMB materials properties (mechanical and chemical), miniaturization of the electronic controller, rotordynamic prediction, fluid and electrical interfaces.
