FIELD: machine building.
SUBSTANCE: hydroelectric turbine includes stator 12 and shaftless rotor 14. Stator 12 restricts an opening in which rotor 14 is installed with possibility of being rotated. The opening allows rotation of rotor 14 about its central axis due to its shape and size, and movement in a circumferential direction of the opening, thus moving in the direction opposite to direction of rotor 14 rotation.
EFFECT: creation of an improved turbine that is characterised with a decreased friction of bearings, which occurs at its start-up, and provides the possibility of cleaning and cooling of bearings during its functioning, which improves operating characteristics of the turbine.
