Kumhanya kwekutenderera kwema hydraulic turbines kwakaderera, kunyanya kune ma vertical hydraulic turbines. Kuti igadzire 50Hz alternating current, hydraulic turbine generator inoshandisa chimiro chema magnetic poles akawanda. Kune hydraulic turbine generator ine 120 revolutions paminiti, ma magnetic poles 25 anodiwa. Sezvo zvakaoma kuona chimiro chine magnetic poles dzakawanda, bepa iri rinopa muenzaniso we hydro-turbine generator ine 12 pears yemagnetic poles.
Rotor ye hydro-generator inoshandisa chimiro chedanda rakakosha. Mufananidzo 1 unoratidza joko nedanda remagineti rejenareta. Goko remagineti rakaiswa pajoko remagineti. Goko remagineti inzira yemutsara wesimba remagineti wedanda remagineti. Goko rega rega rakaputirwa ne coil yekukweva, uye simba rekukweva rinopihwa nejenareta yekukweva yakaiswa pamucheto weshaft huru, kana kuti inopihwa ne external thyristor excitation system (inopihwa ne collector ring kune excitation coil).
Joko rakaiswa pabhureki rerotor, shaft huru yejenareta yakaiswa pakati pebhureki rerotor, uye jenareta yekumutsa kana rin'i yekuunganidza yakaiswa pamucheto wepamusoro weshaft huru.
Musoro wesimbi wejenareta wakagadzirwa nemapepa esimbi esilicon ane simba remagineti rakanaka. Kune migero yakawanda yakapararira zvakaenzana mudenderedzwa remukati mesimbi, iyo inoshandiswa kuisa ma stator coils.
Makoiri e stator akaiswa mu stator slots kuti agadzire ma three-phase windings, phase winding yega yega inoumbwa nema coil akawanda uye yakarongwa zvichienderana nemitemo yakati.
Jenareta yemvura inoiswa padanda remuchina rakagadzirwa nekongiri, uye danda remuchina rinoiswa padanda remuchina. Danda remuchina ndiro danda rekuisa stator iron core negoko rejenareta yemvura. Deredza tembiricha yemhepo inotonhorera yejenareta; furemu yepasi inoiswawo padanda, uye furemu yepasi ine tsiru yekuisa rotor yejenareta. Dhira resimbi rinogona kutsungirira huremu hwerotor, kudedera, kukanganiswa nezvimwe zvinhu.
Isa simbi ye stator core ne stator coil pafuremu, rotor inopinzwa pakati pe stator, uye pane mukana mudiki ne stator. Rotor inotsigirwa ne thrust bearing yefuremu yepasi uye inogona kutenderera zvakasununguka. Isa furemu yepamusoro, uye pakati pefuremu yepamusoro paiswa ne guide bearing. Guider bearing inodzivirira main shaft yejenareta kuti isazununguke uye inoichengeta yakadzikama munzvimbo yepakati. Isa pasi pepuratifomu yepamusoro, isa mudziyo webhurashi kana mota ye excitation, uye modhi ye hydro-generator inoiswa.
Kutenderera kamwe chete kwerotor ye hydro-generator model kuchaita kuti pave ne three-phase AC electromotive force ine ma cycles gumi nemaviri. Kana rotor ikatenderera pa 250 revolutions paminiti, frequency ye alternating current i50 Hz.
