Patent number: 8742635Abstract: A turbo generator (1), including a stator and a rotor (2), has a rotating bell type exciter (3) connected to one end of the rotor (2) and the exciter (3) being equipped with at least one cooler (7). An axial duct (11) with a guide (12) is provided between a cylindrical housing (13) and the outer circumference of the bell type exciter (3). Thus, drawbacks of the prior art are mitigated and the efficiency of the bell type exciter is increased by recovering the dynamic energy of the cooling fluid flow.Type: GrantFiled: March 20, 2007Date of Patent: June 3, 2014Assignee: Alstom Technology Ltd.Inventors: Michel Verrier, Olivier Perros, Lennart Diestel-Feddersen

Publication number: 20070012092Abstract: In a method for testing the thermally induced unbalance of a rotating machine part, in particular the rotor of a turbogenerator, the rotating machine part or the rotor balanced at normal temperature is brought in the demounted state first to nominal rotational speed and held at this, while its temperature is varied and, at the same time, the transient variations in oscillations of the rotating machine part or rotor which are caused are measured. During the test, the rotating machine part or the rotor is surrounded at least partially by a closed heating cell, a cooling medium flows around and/or flows through the rotating machine part or the rotor in the heating cell, and the heating of the rotating machine part or of the rotor takes place essentially due to the flow-dynamic losses arising from the interaction of the rotating machine part or of the rotor with the circulating cooling medium.Type: ApplicationFiled: April 12, 2006Publication date: January 18, 2007Applicant: ALSTOM Technology LtdInventors: Eric Aubriat, Ludovic Bregy, Andrew Holmes, Georg Klein, Eric Veith, Michel Verrier
