The system for suspending and rotating a rotary shaft comprises a motor module (100) comprising a central rotary shaft (110) having at each end a front annular bearing surface (120) defining a conical region (130), a first magnetic bearing module (200) that comprises a rotary shaft (210) having at one end a front annular bearing surface (220) defining a conical region (230) and is adapted to cooperate with one of the front annular bearing surfaces (120) of the motor module (100), and a second magnetic bearing module (300) that comprises a rotary shaft (310) having at one end a front annular bearing surface (320) defining a conical region (330) and is adapted to cooperate with the other front annular bearing surface (120) of the motor module (100). The motor module (100) and the first and second magnetic bearing modules (200, 300) are centered with respect to each other by co-operation between the conical regions (130, 230, 330) and are assembled firmly with a contact pressure by means of a tie-rod (400).
