The front portion (116) of the immersed turbo-generator bulb houses the alternator (5, 19). The intermediate portion (114) houses the gear box (26), and the rear portion has the turbine (122 projecting therefrom. The intermediate portion is of greater diameter than the front portion and they are interconnected by a flange (2). The external cooling is by tubes (7) through which cooling air flows, and having one end connected to orifices through the flange (2).

The invention relates to a rotor with a damper for an alternator with projecting poles. The squirrel cage type screen damper, includes not only conventional polar bars (10) sunk in projecting pole pieces (6a, 6b), but also interpolar bars (22) having wings (26) arranged between consecutive projecting pole pieces and ensuring damping of the components of the variable magnetic flux which are of large space pitch. Application to the production of electric power, in particular by submerged hydro-electric bulb units.

The invention concerns salient poles of synchronous electric machines. It characterized in that the pole shoe of these poles is solid, whereas the polar body is deformable and can follow the thermal expansions of the pole shoe. It is applied to synchronous machines which can start up as asynchronous motors.
