MARINE TURBINE COMPRISING A STATOR, A ROTOR, A FIRST MAGNETIC BEARING SUPPORTING THE ROTOR AND A SECOND SUPPORT BEARING WITH ROLLING ELEMENT(S)

摘要

This marine turbine comprises a stator (12), a rotor (14), the rotor (14) being able to be driven in rotation about an axis of rotation (X) by a stream of a liquid, and at least one first bearing (20A, 20B) for supporting the rotor (14), the or each first bearing (20A, 20B, comprising a magnetic stator element (46A, 46B) secured to the stator (12) and a magnetic rotor element (48A, 48B) secured to the rotor (14). The marine turbine further comprises at least one second bearing (22A, 22B) for supporting the rotor (14), the or each second bearing (22A, 22B) comprising at least one rolling element (50).
