Mfundo yogwiritsira ntchito injini ya asynchronous ya zinthu zitatu iyenera kukhala:
Pamene ma symmetrical atatu-term alternating current akudutsa mumayendedwe atatu a stator, mphamvu yozungulira ya maginito imapangidwa yomwe imazungulira mozungulira mozungulira danga lamkati la stator ndi rotor pa liwiro la synchronous n1.Popeza mphamvu ya maginito yozungulira imayenda pa liwiro la n1, woyendetsa wa rotor amakhala woyima poyamba, kotero woyendetsa rotor amadula stator yozungulira maginito ndikupanga mphamvu ya electromotive (kuwongolera kwa mphamvu ya electromotive kumatsimikiziridwa ndi dzanja lamanja. ulamuliro).Popeza malekezero onse a kondakitala amafupikitsidwa ndi mphete yachidule, pansi pa mphamvu ya electromotive induced, mphamvu yowonongeka idzapangidwa mu rotor conductor yomwe imagwirizana kwambiri ndi kayendetsedwe ka mphamvu ya electromotive.Zoyendetsa zamakono za rotor zimayendetsedwa ndi mphamvu zamagetsi mu mphamvu yamagetsi ya stator (kuwongolera kwa mphamvu kumatsimikiziridwa ndi lamulo lamanzere).Mphamvu yamagetsi imapanga torque yamagetsi pa shaft ya rotor, ndikuyendetsa rotor kuti izungulire mozungulira gawo la maginito ozungulira.
Kupyolera mu kusanthula pamwamba, tinganene kuti mfundo ntchito ya galimoto ndi: pamene atatu stator windings ya galimoto (iliyonse ili ndi kusiyana kwa gawo la madigiri 120 mu ngodya yamagetsi) imaperekedwa ndi mafunde atatu osinthasintha, maginito ozungulira. zidzapangidwa.Mphamvu yamagetsi imapangidwa pozungulira (kuzungulira kwa rotor ndi njira yotsekedwa).Kondakitala yonyamula ma rotor pakali pano ipanga mphamvu yamagetsi motengera mphamvu yamagetsi yozungulira ya stator, motero imapanga torque yamagetsi pa shaft yamoto, kuyendetsa mota kuti izungulire, ndipo kuwongolera kwa injini kumagwirizana ndi maginito ozungulira.Njira yomweyo.
Zifukwa: 1. Ngati mbali imodzi kapena ziwiri zopindika zamoto zimatenthedwa (kapena kutenthedwa), nthawi zambiri zimayamba chifukwa cha kutayika kwa gawo.Sipadzakhala kusanthula kozama kwamalingaliro apa, kungofotokozera mwachidule.Pamene injini itaya gawo pazifukwa zilizonse, ngakhale injiniyo imatha kupitirizabe kuthamanga, liwiro limatsika ndipo slip imakhala yaikulu.Magawo a B ndi C amakhala ubale wotsatizana ndipo amalumikizidwa limodzi ndi gawo la A.Pamene katunduyo amakhalabe osasintha, Ngati panopa gawo A ndi lalikulu kwambiri, ngati likuyenda kwa nthawi yaitali, kugwedezeka kwa gawoli kudzatentha kwambiri ndikutentha.Gawo lamagetsi likatayika, injiniyo imatha kupitilizabe kuthamanga, koma liwiro limatsikanso kwambiri, kutsetsereka kumakhala kokulirapo, ndipo kuchuluka kwa maginito omwe amadula kondakitala kumawonjezeka.Panthawiyi, mafunde a B-gawo amakhala otseguka, ndipo mafunde a A ndi C amakhala otsatizana ndikupita Kugwira ntchito mopitirira muyeso komanso kwanthawi yayitali kumapangitsa kuti magawo awiri aziwotcha nthawi imodzi. onetsani apa kuti ngati injini yoyimitsidwa ilibe gawo limodzi lamagetsi ndipo ikayatsidwa, nthawi zambiri imangotulutsa phokoso ndipo siyingayambe.Izi ndichifukwa choti ma symmetrical magawo atatu osinthira omwe amaperekedwa ku mota amatulutsa mphamvu ya maginito yozungulira pakatikati pa stator.Komabe, gawo limodzi lamagetsi likasowa, gawo limodzi lamphamvu lamagetsi limapangidwa pakatikati pa stator, zomwe sizingapangitse injini kupanga torque yoyambira.Chifukwa chake, injini siyingayambe pomwe gawo lamagetsi likusowa.Komabe, panthawi yogwira ntchito, maginito ozungulira ozungulira omwe ali ndi magawo atatu amtundu wa harmonic amapangidwa mu mpweya wa injini.Chifukwa chake, mota yothamanga imathabe kuthamanga pambuyo pa kutayika kwa gawo, koma mphamvu ya maginito imasokonekera ndipo gawo loyipa lapano limakula kwambiri., potsirizira pake kuchititsa kuti chimphepocho chiwonongeke.
Njira zofananira: Ziribe kanthu kaya injiniyo ili yokhazikika kapena yosunthika, kuvulaza mwachindunji chifukwa cha kutayika kwa gawo ndikuti mapindikidwe a gawo limodzi kapena awiri amatenthedwa kapena kupsa.Pa nthawi yomweyo, overcurrent ntchito zingwe mphamvu Imathandizira kutchinjiriza kukalamba.Makamaka m'malo osasunthika, kusowa kwa gawo kumatulutsa makina okhoma okhoma kangapo kuposa momwe amayendera pamapiritsi amagalimoto.Kuthamanga kwapang'onopang'ono kumakhala kofulumira komanso koopsa kuposa kutayika kwadzidzidzi panthawi ya ntchito.Chifukwa chake, tikamakonza ndikuyang'anira galimoto tsiku lililonse, tiyenera kuyang'ana mozama ndikuyesa gawo lolingana la MCC la injiniyo.Makamaka, kudalirika kwa masiwichi onyamula katundu, mizere yamagetsi, ndi kulumikizana kokhazikika komanso kosunthika kuyenera kuyang'aniridwa mosamala.Pewani ntchito yotaya gawo.
