Jenareta yemvura inoumbwa nerotor, stator, furemu, thrust bearing, guide bearing, cooler, brake nezvimwe zvinhu zvikuru (ona mufananidzo). Stator inonyanya kugadzirwa nehwaro, simbi, uye mawindings. Stator core yakagadzirwa nesimbi yesilicon yakaputirwa inotonhora, iyo inogona kugadzirwa kuita chimiro chakapatsanurwa uye chakapatsanurwa zvichienderana nemamiriro ekugadzira uye ekufambisa. Nzira yekutonhodza yejenareta yeturbine yemvura inowanzo tora kutonhodza kwemhepo inotenderera yakavharwa. Mayuniti ane simba guru anowanzo shandisa mvura senzvimbo yekutonhodza kuti itonhodze stator zvakananga. Kana stator nerotor zvikatonhodzwa panguva imwe chete, ijenareta yeturbine yemvura inotonhodzwa kaviri mukati memvura.
Kuti iwedzere kugona kweyuniti imwe chete ye hydro-generator uye kukura kuita yuniti hombe, kuti ivandudze kuvimbika kwayo uye kugara kwenguva refu, matekinoroji matsva akawanda ashandiswa muchimiro ichi. Semuenzaniso, kuti igadzirise kuwedzera kwekupisa kwe stator, chimiro chinoyangarara che stator, rutsigiro rwe oblique, nezvimwewo zvinoshandiswa, uye rotor inoshandisa chimiro che disc. Kuti igadzirise kusunungura kwe stator coils, elastic wedges inoshandiswa kuisa pasi pemitsetse kudzivirira insulation ye wire rods kuti isaparare. Kuvandudza chimiro chemhepo yekufema kuderedza kurasikirwa nemhepo uye kurasikirwa kwe eddy current kuti iwedzere kushanda zvakanaka kweyuniti.
Nekuvandudzwa kwetekinoroji yekugadzira maturbine emvura, kumhanya uye kugona kwemamota ejenareta kuri kuwedzerawo, zvichivandudzika kusvika pakukwanisa kukuru uye kumhanya kukuru. Munyika yose, nzvimbo dzemagetsi dzakavakwa dzakashongedzerwa nemamota ejenareta ane simba guru uye anomhanya zvikuru dzinosanganisira Dinovic Pumped Storage Power Station (330,000 kVA, 500r/min) muUnited Kingdom nezvimwewo.
Uchishandisa mamota ejenareta ekutonhodza emukati memvura maviri, stator coil, rotor coil uye stator core zvinotonhodzwa zvakananga mukati memvura ine ionized, izvo zvinogona kuwedzera muganho wekugadzirwa kwemota yejenareta. Mota yejenareta (425,000 kVA, 300r/min) yeLa Kongshan Pumped Storage Power Station muUnited States inoshandisawo kutonhodza kwemukati memvura kaviri.
Kushandiswa kwema "magnetic thrust bearing". Sezvo kugona kwemota yejenareta kuchiwedzera, kumhanya kunowedzera, saka "thrust load" uye "starting torque" yeyuniti inowedzerawo. Mushure mekushandisa "magnetic thrust bearing", "thrust load" inowedzerwa ne "magnetic attraction" kune rimwe divi regiravhiti, nokudaro ichideredza "thrust bearing load", ichideredza "axial resistance loss", ichideredza "bearing temperature" uye ichivandudza kushanda kweyuniti, uye "starting resistance" inodererawo. "Jenareta" (335,000 kVA, 300r/min) yeSanglangjing Pumped Storage Power Station muSouth Korea inoshandisa "magnetic thrust bearingers".
