Janareta na ruwa ya ƙunshi rotor, stator, firam, thrust bearing, guide bearing, cooler, birki da sauran manyan sassan (duba Hoto). Stator ya ƙunshi firam, ƙarfe core, naɗewa da sauran sassan. 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. Gabaɗaya janareta na turbine na ruwa galibi ana sanyaya shi ta hanyar iska mai rufewa. Manyan na'urori masu ƙarfi suna amfani da ruwa azaman matsakaiciyar sanyaya don sanyaya stator kai tsaye. Idan stator da rotor sun sanyaya a lokaci guda, saitin janareta ne na cikin ruwa mai sanyaya biyu.
Domin inganta ƙarfin injin samar da ruwa guda ɗaya da kuma haɓaka zuwa babban na'ura, ana amfani da sabbin fasahohi da yawa a cikin tsari don inganta aminci da dorewarsa. Misali, don magance faɗaɗa zafin stator, ana amfani da tsarin iyo na stator da tallafin lanƙwasa, kuma rotor yana ɗaukar tsarin diski. Domin magance sassautawar coil na stator, ana amfani da tsiri mai laushi a ƙarƙashin wedge mai laushi don hana lalacewar sandar waya. Inganta tsarin iska da rage asarar iska da kuma kawo ƙarshen asarar wutar lantarki don ƙara inganta ingancin na'urar.
Tare da haɓaka fasahar kera injinan famfo, saurin da ƙarfin injin janareta suma suna ƙaruwa, suna haɓaka zuwa babban ƙarfin aiki da babban gudu. Tashoshin wutar lantarki da aka gina waɗanda ke da manyan ƙarfin aiki da injinan samar da wutar lantarki masu sauri a duniya sun haɗa da tashar wutar lantarki da aka ɗora wa injinan dinowick (330000 KVA, 500r / min) a Burtaniya.
