I-hydro-generator yakhiwe nge-rotor, i-stator, ifreyimu, i-thrust bear, i-guide bear, i-cooler, i-brake nezinye izingxenye eziyinhloko (bheka isithombe). I-stator yakhiwa ikakhulukazi isisekelo, i-iron core, nama-windings. I-stator core yenziwe ngamashidi ensimbi e-silicon egoqwe abandayo, angenziwa abe yisakhiwo esibalulekile nesihlukanisayo ngokuya ngezimo zokukhiqiza nezokuthutha. Indlela yokupholisa yejeneretha ye-turbine yamanzi ngokuvamile isebenzisa ukupholisa komoya okuvalekile. Amayunithi amakhulu avame ukusebenzisa amanzi njengendawo yokupholisa ukuze apholise ngokuqondile i-stator. Uma i-stator ne-rotor zipholiswa ngesikhathi esifanayo, isethi yamanzi amabili epholile ngaphakathi ejeneretha ye-turbine yamanzi.
Ukuze kwandiswe umthamo weyunithi eyodwa ye-hydro-generator futhi ithuthuke ibe yiyunithi enkulu, ukuze kuthuthukiswe ukwethembeka nokuqina kwayo, kusetshenziswe ubuchwepheshe obusha obuningi esakhiweni. Isibonelo, ukuze kuxazululwe ukunwetshwa kokushisa kwe-stator, isakhiwo esintantayo se-stator, ukusekelwa kwe-oblique, njll kuyasetshenziswa, futhi i-rotor ithatha isakhiwo se-disc. Ukuze kuxazululwe ukuxega kwamakhoyili e-stator, amaweji anwebekayo asetshenziselwa ukumboza imichilo ukuze kuvinjelwe ukuguga kwezinduku zocingo. Thuthukisa isakhiwo sokungenisa umoya ukuze unciphise ukulahlekelwa komoya futhi uqede ukulahlekelwa kwamanje kwe-eddy ukuze uthuthukise ukusebenza kahle kweyunithi.
Ngokuthuthukiswa kobuchwepheshe bokukhiqiza i-turbine yephampu yamanzi, isivinini namandla ama-generator motors nawo ayanda, athuthukela kumthamo omkhulu kanye nesivinini esikhulu. Emhlabeni, iziteshi zamandla ezigciniwe ezakhiwe ezifakwe amandla amakhulu, ama-generator motors anesivinini esikhulu zihlanganisa i-Dinovic Pumped Storage Power Station (330,000 kVA, 500r/min) e-United Kingdom njalonjalo.
Ukusebenzisa ama-generator ejeneretha okupholisa amanzi amabili angaphakathi, ikhoyili ye-stator, ikhoyili ye-rotor kanye ne-stator core kupholiswe ngokuqondile ngaphakathi ngamanzi ane-ionized, angandisa umkhawulo wokukhiqiza we-generator motor. Injini yokuphehla ugesi (425,000 kVA, 300r/min) yeSiteshi Samandla SeSitoreji Se-La Kongshan Pumped e-United States siphinde sisebenzisa ukupholisa kwamanzi okukabili kwangaphakathi.
Ukusetshenziswa kwamagnetic thrust bearings. Njengoba umthamo we-generator motor ukhula, ijubane liyakhula, kanjalo nomthwalo we-thrust kanye ne-torque yokuqala yeyunithi. Ngemuva kokusebenzisa i-magnetic thrust bearing, umthwalo we-thrust wengezwa ngokukhanga kazibuthe ngakolunye uhlangothi lwe-gravity, ngaleyo ndlela kuncishiswe umthwalo othwala i-thrust, ukunciphisa ukulahlekelwa ukumelana ne-axial, ukunciphisa izinga lokushisa lokuthwala nokuthuthukisa ukusebenza kahle kweyunithi, kanye nokumelana kokuqala Umzuzu nawo uyancipha. I-generator motor (335,000 kVA, 300r/min) ye-Sanglangjing Pumped Storage Power Station e-South Korea isebenzisa ama-thrust bearings kazibuthe.
