Intro
Muna 1832, mudiki wechiFrench mainjiniya emagetsi Pixy akabudirira kuyedza-akagadzira pasirese yekutanga-yakarebesa ruoko-yakareba magineti inotenderera jenareta.
Mune jenareta iyi, Pixie akaisa yekutanga commutator, iyo yakashandura ikozvino inotenderera yakagadzirwa mujenareta kuita yakatwasuka yaivepo inodiwa pakugadzira kutengeserana kumashure.Zvakangodaro, Pixie isingadzoreki magineti mhando Majenareta ane maviri akasiyana akashata.Chekutanga, midziyo yayo yakakura zvine mutsindo, uye zvakaoma kukwidziridza simba nekuwedzera kumhanya.Chechipiri, simba rayo rekukurudzira ndeye manpower, izvo zvakare zvakaoma kuwana yakakwirira-simba riripo nekuwedzera chiyero.
Panguva imwecheteyo iyo Pixie akavandudza jenareta yake yenguva refu yemaginereta, vamwe vanhu vakadzidzawo iyo isingachinjiki maginereta uye vakaita zvimwe zvakakosha zvitsva.Kubva 1833 kusvika 1835, Sushston pamwe naClark pamwe nevamwe vakagadzira michina mitsva yakadai sekutenderedza coil armature pamwe neyakamira magineti framework.Kutendeuka kumhanya.
Kubva ipapo, vanhu vakashandurawo simba rekukurudzira gadget yejenareta, kushandura dhiri kuenda kune inotenderera shaft, uye zvakare kushandura ruoko kuti rwufambiswe neinjini yemhute.Nekuita izvi, kumhanya kwakavandudzwa zvakanyanya, uye zvakare huwandu hwesimba remagetsi rakagadzirwa hwakanyanya kusimudzwa.
Pahwaro hweiyo yepamusoro 2 matekinoroji, mamwe mashoma matekinoroji akaitwa zvakare.Pakazosvika 1844, muFrance, Germany, Britain nedzimwe nyika, pari zvino pakanga paine majenareta akakura uye asinganetseki ekupa simba idzva remagetsi emagetsi, uye kupa magetsi matsva kumichina kuburikidza neiyo yekutanga mota yemagetsi.
Kuberekwa kwechigarire magineta jenareta ndiyo nguva yekutanga kuti simba remagetsi rinoshandurwa kubva kusimba rinopisa rinoshandurwa kuita simba remagetsi, kuitira kuti vanhu vawane simba idzva rine tarisiro yakakura mushure mesimba rekupisa.
