HYDROLIENNE COMPRISING A STATOR, A ROTOR, A FIRST MAGNETIC ROTOR SUPPORT BEARING AND A SECOND SUPPORT BEARING WITH ROLLING ELEMENT (S)

摘要

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