ABSTRACT:
An hydroelectric machine is disclosed wherein the rotor of an electric machine is arranged around the rotor of a hydraulic machine, the internal rotor comprising the turbine blades which engage the external rotor to transmit torque therebetween. Each of the internal and external rotors is mounted in a separate radial bearing and the turbine blades of the internal rotor are connected to the external rotor by means of an articulated coupling which permits relative radial movement therebetween. It is preferred to include force compensating means for transmitting circumferential forces between the rotors. Suitable such means comprise an hydraulic servo-motor associated with each blade of which the pressure chambers are interconnected by means of a ring conduit.
