Jenereta wa maginito osatha

Masiku ano ma motors amagetsi a DC, njira yosangalatsa yomwe imagwiritsa ntchito DC panopa kuti ipange malo akuluakulu a electromagnetic imatchedwa chisangalalo;ngati maginito osasinthika agwiritsidwa ntchito m'malo mwachisangalalo chomwe chilipo kuti apange gawo lalikulu lamagetsi amagetsi, mtundu uwu wagalimoto yamagetsi umatchedwa injini yamagetsi yosasinthika.

Brushless imatha kupezeka nthawi zambiri, chifukwa chake imagwiritsidwa ntchito kwambiri mumagetsi ang'onoang'ono komanso ang'onoang'ono amagetsi.Mukamagwiritsa ntchito magetsi osinthika pafupipafupi, maginito osasinthika amathanso kugwiritsidwa ntchito pamakina owongolera ma frequency.Ndi kukonzanso kosalekeza komanso kuwongolera bwino kwa zinthu zosasinthika maginito, ma mota amagetsi anthawi yayitali akhala akugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga zida zabanja, zida zamankhwala, magalimoto, ndege komanso chitetezo chamayiko.

Choyipa cha injini yanthawi yayitali ya maginito ndikuti ngati igwiritsidwa ntchito molakwika, ikamagwira ntchito yotsika mtengo kapena yocheperako kutentha, pansi pakuchitapo kanthu kwa kuyankha kwamphamvu komwe kumapangidwa ndi inrush pano, kapena pansi pamphamvu yamakina, imatha. pangani zowonongeka zosasinthika.Demagnetization imapangitsa magwiridwe antchito agalimoto kukhala ofooka kapena opanda pake.Pachifukwa ichi, chithandizo chapadera chiyenera kuchitidwa pogwiritsa ntchito maginito okhazikika.
Chiyambi

Mu 1832, injiniya wachinyamata wa ku France wamagetsi a Pixy adayesa moyeserera padziko lonse lapansi kuti apange jenereta yozungulira yanthawi yayitali ya maginito.

Mu jenereta iyi, Pixie adayika makina oyambira, omwe adasintha magetsi ozungulira omwe adapangidwa mu jenereta kukhala yowongoka yomwe imayenera kupanga malonda kalelo.Komabe, majenereta osasinthika a Pixie amtundu wa maginito ali ndi zovuta ziwiri zosiyana.Choyamba, zida zake ndizokulirapo, ndipo zimakhala zovuta kukulitsa mphamvu mwa kuwonjezera liwiro.Chachiwiri, mphamvu yake ndi ya anthu ogwira ntchito, omwenso ndi ovuta kupeza mphamvu zapamwamba poonjezera mlingo.

Nthawi yomweyo Pixie adakulitsa jenereta yake yanthawi yayitali ya maginito, anthu ena adaphunziranso za jenereta yosasinthika ya maginito ndikupanga zinthu zina zofunika.Kuyambira 1833 mpaka 1835, Sushston komanso Clark komanso ena onse pamodzi adapanga zida zatsopano monga kutembenuza ma coil armature komanso maginito okhazikika.Kutembenuza liwiro.

Kuyambira nthawi imeneyo, anthu asinthanso mphamvu yamagetsi ya jenereta, kusintha mgwirizano ndi shaft yozungulira, komanso kusintha dzanja kuti liziyendetsedwa ndi injini ya nthunzi.Pochita izi, liwiro lakhala likuyenda bwino, komanso kuchuluka kwa mphamvu zamagetsi zomwe zidapangidwa zakwera kwambiri.

Pamaziko a matekinoloje apamwamba a 2, matekinoloje ena ochepa apangidwanso.Pofika cha m’ma 1844, ku France, Germany, Britain ndi mayiko ena, pakali pano panali majenereta akuluakulu komanso ovuta kuti apereke mphamvu zatsopano za electrolysis, komanso kupereka mphamvu zatsopano kumakina kudzera pa injini yamagetsi yoyamba.

Kubadwa kwa okhazikika maginito jenereta ndi nthawi yoyamba kuti mawotchi mphamvu kusandulika mphamvu matenthedwe n'kukhala mphamvu yamagetsi, kuti anthu apeza mphamvu yatsopano ndi chiyembekezo lonse pambuyo matenthedwe mphamvu.
