Injin samar da wutar lantarki ya ƙunshi rotor, stator, firam, thrust bearing, guide bearing, cooler, birki da sauran manyan abubuwan haɗin gwiwa (duba hoto). Stator galibi ya ƙunshi tushe, ƙarfe core, da windings. An yi tsakiyar stator ɗin ne da zanen ƙarfe na silicon mai sanyi, wanda za'a iya yin shi cikin tsari mai haɗaka da raba bisa ga yanayin masana'antu da sufuri. Hanyar sanyaya injin samar da wutar lantarki na ruwa gabaɗaya tana amfani da iska mai rufewa. Na'urori masu girman gaske suna amfani da ruwa azaman hanyar sanyaya don sanyaya stator kai tsaye. Idan stator da rotor sun sanyaya a lokaci guda, saitin janareta ne na ruwa mai sanyaya a ciki biyu.
Domin ƙara ƙarfin injin samar da wutar lantarki mai amfani da na'urar samar da wutar lantarki guda ɗaya da kuma haɓaka ta zuwa babban na'ura, domin inganta aminci da dorewarta, an yi amfani da sabbin fasahohi da yawa a cikin tsarin. Misali, domin magance faɗaɗa zafin stator, ana amfani da tsarin iyo na stator, tallafin oblique, da sauransu, kuma rotor yana ɗaukar tsarin diski. Domin magance sassauta na'urorin stator, ana amfani da wedges masu roba don rufe layukan don hana rufin sandunan waya lalacewa. Inganta tsarin iska don rage asarar iska da kuma kawo ƙarshen asarar wutar lantarki don ƙara inganta ingancin na'urar.
Tare da haɓaka fasahar kera injinan injinan famfon ruwa, saurin da ƙarfin injinan janareta suma suna ƙaruwa, suna haɓaka zuwa babban ƙarfin aiki da babban gudu. A duniya, tashoshin wutar lantarki da aka gina waɗanda ke da manyan injinan janareta masu sauri sun haɗa da Tashar Wutar Lantarki ta Dinovic Pumped Storage (330,000 kVA, 500r/min) a Burtaniya da sauransu.
Ta amfani da injinan sanyaya ruwa guda biyu, ana sanyaya na'urar stator coil, rotor coil da kuma core stator kai tsaye da ruwan ionized, wanda zai iya ƙara yawan ƙarfin injin janareta. Injin janareta (425,000 kVA, 300r/min) na Tashar Wutar La Kongshan da aka ɗora a Amurka shi ma yana amfani da sanyaya ruwa guda biyu a ciki.
Amfani da bearings na magnetic pressure bearings. Yayin da ƙarfin injin janareta ke ƙaruwa, saurin yana ƙaruwa, haka nan nauyin turawa da ƙarfin farawa na na'urar ke ƙaruwa. Bayan amfani da bearings na magnetic pressure bearings, ana ƙara nauyin turawa tare da jan hankalin magnetic a akasin alkiblar nauyi, ta haka ne rage nauyin turawa, rage asarar juriya ta axial, rage zafin ɗaukar kaya da inganta ingancin na'urar, da juriyar farawa. Lokacin kuma yana raguwa. Injin janareta (335,000 kVA, 300r/min) na Tashar Wutar Lantarki ta Sanglangjing da aka ɗora a Koriya ta Kudu yana amfani da bearings na magnetic pressure bearings.
