Jenereta ya hydro imapangidwa ndi rotor, stator, chimango, thrust bearing, guide bearing, cooler, brake ndi zinthu zina zazikulu (onani chithunzi). Stator imapangidwa makamaka ndi maziko, chitsulo, ndi ma windings. Stator core imapangidwa ndi mapepala achitsulo a silicon ozungulira ozizira, omwe amatha kupangidwa kukhala ophatikizika komanso ogawanika malinga ndi momwe zinthu zimakhalira komanso momwe zimayendera. Njira yozizira ya jenereta ya turbine yamadzi nthawi zambiri imagwiritsa ntchito kuziziritsa mpweya wozungulira wotsekedwa. Mayunitsi akuluakulu amagwiritsa ntchito madzi ngati njira yozizira kuti aziziritse stator mwachindunji. Ngati stator ndi rotor zitaziritsidwa nthawi imodzi, ndi seti ya jenereta ya turbine yamadzi yozizira kawiri.
Pofuna kuwonjezera mphamvu ya unit imodzi ya hydro-generator ndikupanga unit yayikulu, kuti iwonjezere kudalirika ndi kulimba kwake, ukadaulo watsopano wagwiritsidwa ntchito mu kapangidwe kake. Mwachitsanzo, kuti athetse kufalikira kwa kutentha kwa stator, kapangidwe koyandama ka stator, chithandizo cha oblique, ndi zina zotero zimagwiritsidwa ntchito, ndipo rotor imagwiritsa ntchito kapangidwe ka disc. Kuti athetse kumasuka kwa ma stator coils, ma elastic wedges amagwiritsidwa ntchito kuyika pansi pa mipiringidzo kuti ateteze kusungunuka kwa waya kuti usawonongeke. Konzani kapangidwe ka mpweya kuti muchepetse kutayika kwa mphepo ndi kutayika kwa eddy current kuti muwongolere magwiridwe antchito a chipangizocho.
Ndi chitukuko cha ukadaulo wopanga ma turbine a pampu yamadzi, liwiro ndi mphamvu ya ma mota a jenereta zikuwonjezekanso, zomwe zikupita patsogolo kufika pa mphamvu yayikulu komanso liwiro lalikulu. Padziko lonse lapansi, malo osungira magetsi omangidwa okhala ndi ma mota a jenereta amphamvu komanso othamanga kwambiri akuphatikizapo Dinovic Pumped Storage Power Station (330,000 kVA, 500r/min) ku United Kingdom ndi zina zotero.
Pogwiritsa ntchito ma mota a jenereta yoziziritsira mkati mwa madzi awiri, stator coil, rotor coil ndi stator core zimaziziritsidwa mkati mwachindunji ndi madzi a ionized, zomwe zitha kuwonjezera malire opangira jenereta. Jenereta ya jenereta (425,000 kVA, 300r/min) ya La Kongshan Pumped Storage Power Station ku United States imagwiritsanso ntchito kuziziritsa madzi mkati mwa awiri.
Kugwiritsa ntchito ma magnetic thrust bearing. Pamene mphamvu ya injini ya jenereta ikuwonjezeka, liwiro limawonjezeka, momwemonso thrust load ndi starting torque ya unit imakulirakulira. Mukagwiritsa ntchito magnetic thrust bearing, thrust load imawonjezedwa ndi magnetic attraction kumbali ina ya mphamvu yokoka, motero imachepetsa thrust bearing load, imachepetsa axial resistance loss, imachepetsa kutentha kwa bearing ndikukweza magwiridwe antchito a unit, komanso starting resistance. Moment imachepanso. Jenereta ya jenereta (335,000 kVA, 300r/min) ya Sanglangjing Pumped Storage Power Station ku South Korea imagwiritsa ntchito ma magnetic thrust bearings.
