Kumbuyo electromotive mphamvu kwaiye ndi kutsutsa chizolowezi panopa mu mapiringidzo kusintha. Kumbuyo electromotive mphamvu kwaiye mu zinthu zotsatirazi: (1) pamene alternating panopa kudutsa koyilo; (2) pamene kondakitala aikidwa mu alternating field magnetic field; (3) pamene kondakitala akudula mphamvu ya maginito. Zida zamagetsi monga ma coil a relay, ma valve a electromagnetic, ma coil olumikizirana, ndi ma windings amagalimoto zikugwira ntchito, zonse zimapanga mphamvu yamagetsi.
Kupanga kwanthawi yayitali kumafunikira zinthu ziwiri zofunika: choyamba, loop yotsekeka. Chachiwiri, kumbuyo electromotive mphamvu. Titha kumvetsetsa chodabwitsa cha mphamvu yopangira ma elekitiromu kuchokera ku injini yolowera: magawo atatu ofananira voteji amagwiritsidwa ntchito pamayendedwe a stator agalimoto ndi kusiyana kwa madigiri 120, ndikupanga maginito ozungulira, kotero kuti mipiringidzo yozungulira imayikidwa mu izi. Mphamvu yozungulira ya maginito imayendetsedwa ndi mphamvu yamagetsi, kusintha kuchoka ku static kupita kumayendedwe ozungulira, kutulutsa kuthekera kochititsa chidwi m'mipiringidzo, komanso kuyenderera kwaposachedwa kupyolera mu chipika chotsekedwa cha mipiringidzo yolumikizidwa ndi mphete zomaliza. Mwanjira imeneyi, mphamvu yamagetsi kapena mphamvu ya electromotive imapangidwa muzitsulo zozungulira, ndipo mphamvu ya electromotive iyi ndi yomwe imatchedwanso mphamvu ya electromotive. Mu chilonda chozungulira mota, voteji yotseguka ya rotor ndi mphamvu yakumbuyo yamagetsi.
Mitundu yosiyanasiyana yama motors imakhala ndi kusintha kosiyana kosiyana mu kukula kwa mphamvu yakumbuyo ya electromotive. Kukula kwa mphamvu yakumbuyo yama electromotive ya asynchronous motor kusintha ndi kukula kwa katundu nthawi iliyonse, zomwe zimapangitsa kuti pakhale zizindikiro zosiyana kwambiri pamikhalidwe yosiyanasiyana ya katundu; mu okhazikika maginito galimoto, bola liwiro akadali zosasinthika, kukula kwa kumbuyo electromotive mphamvu amakhalabe zosasinthika, kotero zizindikiro dzuwa pansi pa zinthu zosiyanasiyana katundu amakhalabe sasintha.
Tanthauzo lakuthupi la mphamvu yakumbuyo ya electromotive ndi mphamvu ya electromotive yomwe imatsutsa ndimeyi yamakono kapena kusintha kwamakono. Muubwenzi wosinthira mphamvu yamagetsi UIt=ε逆It+I2Rt, UIt ndi mphamvu yamagetsi yolowetsa, monga kulowetsa mphamvu yamagetsi ku batri, mota kapena thiransifoma; I2Rt ndi mphamvu yotaya kutentha m'dera lililonse, yomwe ndi mtundu wa mphamvu yotaya kutentha, yaying'ono ndi yabwino; kusiyana pakati pa mphamvu yamagetsi yolowetsamo mphamvu yamagetsi ndi kutentha kwa mphamvu yamagetsi ndi gawo la mphamvu yothandiza ε逆Iyo ikugwirizana ndi mphamvu yakumbuyo ya electromotive. Mwa kuyankhula kwina, mphamvu yakumbuyo ya electromotive imagwiritsidwa ntchito kupanga mphamvu zothandiza ndipo imagwirizana mosagwirizana ndi kutaya kutentha. Kuchuluka kwa mphamvu yotaya kutentha, kumakhala kochepa mphamvu yothandiza yotheka.
Kunena zowona, EMF yakumbuyo imadya mphamvu zamagetsi muderali, koma si "kutaya". Gawo la mphamvu yamagetsi yogwirizana ndi EMF yakumbuyo idzasinthidwa kukhala mphamvu yothandiza pazida zamagetsi, monga mphamvu yamakina agalimoto ndi mphamvu yamankhwala a batri.
Zitha kuwoneka kuti kukula kwa EMF yam'mbuyo kumatanthauza mphamvu ya zida zamagetsi zomwe zimatha kusintha mphamvu zonse zowonjezera kukhala mphamvu zothandiza, kuwonetsera mphamvu ya kutembenuka kwa zipangizo zamagetsi.
Zomwe zimatsimikizira kumbuyo kwa EMF Pazinthu zamagalimoto, kuchuluka kwa makhoti a stator, kuthamanga kwa rotor angular, maginito opangidwa ndi maginito ozungulira, komanso kusiyana kwa mpweya pakati pa stator ndi rotor ndi zinthu zomwe zimatsimikizira kumbuyo kwa EMF yagalimoto. . injini ikapangidwa, maginito a rotor ndi kuchuluka kwa mafunde a stator amatsimikiziridwa. Chifukwa chake, chinthu chokhacho chomwe chimatsimikizira kumbuyo kwa EMF ndi liwiro la rotor angular, kapena liwiro la rotor. Pamene liwiro la rotor likuwonjezeka, EMF yakumbuyo imakulanso. Kusiyanitsa pakati pa stator m'mimba mwake ndi m'mimba mwake ya rotor kudzakhudza kukula kwa maginito a maginito, zomwe zidzakhudzanso kumbuyo kwa EMF.
Zomwe muyenera kudziwa injini ikamathamanga ● Ngati galimotoyo ikusiya kuzungulira chifukwa cha kukana kwa mawotchi, palibe mphamvu yamagetsi yobwerera kumbuyo panthawiyi. Koyilo yokhala ndi kukana kochepa kwambiri imalumikizidwa mwachindunji ndi malekezero awiri amagetsi. Yapano idzakhala yayikulu kwambiri, yomwe imatha kuwotcha mota mosavuta. Mkhalidwe uwu udzakumana ndi mayeso a mota. Mwachitsanzo, kuyesa kwa khola kumafuna kuti rotor ya injini ikhale yoyima. Panthawiyi, galimotoyo ndi yaikulu kwambiri ndipo ndiyosavuta kuwotcha galimotoyo. Pakalipano, opanga magalimoto ambiri amagwiritsa ntchito kusonkhanitsa mtengo pompopompo poyesa mayeso, zomwe zimapewa vuto la kuyatsa kwamoto chifukwa cha nthawi yayitali. Komabe, popeza mota iliyonse imakhudzidwa ndi zinthu zosiyanasiyana monga kusonkhana, zosonkhanitsidwa ndizosiyana kwambiri ndipo sizingawonetsere momwe injiniyo imayambira.
● Mphamvu yamagetsi yolumikizidwa ndi injini ikatsika kwambiri kuposa mphamvu yanthawi zonse, koyilo yamoto sidzazungulira, palibe mphamvu yakumbuyo yamagetsi yomwe imapangidwa, ndipo injiniyo imatha kuzima mosavuta. Vutoli nthawi zambiri limapezeka pamakina omwe amagwiritsidwa ntchito pamizere yosakhalitsa. Mwachitsanzo, mizere yosakhalitsa imagwiritsa ntchito zingwe zamagetsi. Chifukwa amagwiritsidwa ntchito kamodzi komanso kupewa kuba, ambiri a iwo amagwiritsa ntchito mawaya a aluminiyamu pakuwongolera mtengo. Mwanjira imeneyi, kutsika kwa voteji pamzere kudzakhala kwakukulu kwambiri, zomwe zimapangitsa kuti voteji ikhale yosakwanira yamagetsi. Mwachilengedwe, mphamvu yakumbuyo yama electromotive iyenera kukhala yaying'ono. Zikavuta kwambiri, injiniyo imakhala yovuta kuyambitsa kapena kulephera kuyiyambitsa. Ngakhale injiniyo ikayamba, imathamanga kwambiri pakanthawi kochepa, motero injiniyo imatha kupsa mosavuta.
