<p>A submerged hydrogenerator (1) converts water flow energy into electrical energy, and comprises: a stator (2) defining an inner stator opening, the stator comprising electrical stator windings (22); an annular rotor (3) rotatably mounted in the stator opening and defining an inner rotor opening (4) in which propeller blades (5) of the rotor are mounted to be engaged by water flowing axially through the rotor opening in a first direction (9), the rotor comprising a magnetic structure (30) configured to interact with the stator windings to generate electrical energy when the rotor rotates relative to the stator; and a water lubricated radial tiltable pad bearing assembly (44, 40). An axial bearing assembly comprises repulsive permanent magnet units (60, 62) to axially force the rotor in a second direction (64) relative to the stator opposite said first direction, and an axial stop assembly (66) to limit axial movement of the rotor in said second direction.</p> |
