Jenereta ya hydro imapangidwa ndi rotor, stator, chimango, thrust bearing, guide bearing, cooler, brake ndi zigawo zina zazikulu (onani Chithunzi). Stator imapangidwa makamaka ndi chimango, chitsulo, winding ndi zigawo zina. Stator core imapangidwa ndi mapepala achitsulo a silicon ozungulira ozizira, omwe amatha kupangidwa kukhala kapangidwe kogwirizana ndi kogawanika malinga ndi momwe zinthu zimakhalira komanso momwe zimayendera. Jenereta ya turbine yamadzi nthawi zambiri imazizira ndi mpweya wozungulira wotsekedwa. Mayunitsi akuluakulu okhala ndi mphamvu amagwiritsa ntchito madzi ngati njira yozizira kuti aziziritse stator mwachindunji. Pamene stator ndi rotor zitaziziritsidwa nthawi imodzi, zimakhala jenereta ya mawilo ozizira amkati mwa madzi awiri.
Pofuna kukweza mphamvu ya unit imodzi ya hydro generator ndikupangitsa kuti ikhale unit yayikulu, ukadaulo watsopano wambiri umagwiritsidwa ntchito kuti ukhale wodalirika komanso wolimba. Mwachitsanzo, pofuna kuthetsa kufalikira kwa kutentha kwa stator, kapangidwe ka stator koyandama ndi chithandizo chopendekeka zimagwiritsidwa ntchito, ndipo rotor imagwiritsa ntchito kapangidwe ka disc. Pofuna kuthetsa kusasunthika kwa stator coil, cushion strip pansi pa elastic wedge imagwiritsidwa ntchito kuti ipewe kutayika kwa insulation ya waya. Kukonza kapangidwe ka mpweya wabwino ndikuchepetsa kutayika kwa mphepo ndi kutayika kwa eddy current kuti ipititse patsogolo kugwira ntchito bwino kwa unit.
Ndi chitukuko cha ukadaulo wopanga ma turbine opompa, liwiro ndi mphamvu ya injini ya jenereta zikuwonjezekanso, zomwe zikukula kufika pamphamvu yayikulu komanso liwiro lalikulu. Malo osungira mphamvu omangidwa okhala ndi ma mota amphamvu komanso amphamvu kwambiri padziko lonse lapansi akuphatikizapo malo osungira magetsi opompa a dinowick (330000 KVA, 500r / min) ku UK.
Pogwiritsa ntchito injini ya jenereta yoziziritsira mkati mwa madzi awiri, coil ya stator, coil ya rotor ndi stator core zimaziziritsidwa mwachindunji mkati ndi madzi a ionic, zomwe zingathandize kuchepetsa malire opangira injini ya jenereta. Jenereta ya jenereta (425000 KVA, 300r / min) ya malo osungira magetsi opopera a lakongshan ku United States imagwiritsanso ntchito kuziziritsa mkati mwa madzi awiri.
Kugwiritsa ntchito mphamvu ya magnetic thrust bearing. Pamene mphamvu ya injini ya jenereta ikuwonjezeka komanso liwiro lake, mphamvu ya thrust ndi starting torque ya unit zikuwonjezekanso. Mukagwiritsa ntchito mphamvu ya magnetic thrust bearing, mphamvu ya thrust imawonjezera mphamvu ya magnetic ku mbali ina ya mphamvu yokoka, zomwe zimachepetsa mphamvu ya thrust bearing, zimachepetsa kutayika kwa shaft surface resistance, zimachepetsa kutentha kwa bearing ndikukweza magwiridwe antchito a unit, ndipo nthawi yoyambira yokana imachepetsedwanso. Mphamvu ya magnetic thrust bearing imagwiritsidwa ntchito pa jenereta ya jenereta (335000 KVA, 300r / min) ya sanglangjing pumped storage power station ku South Korea.
