Motereshaft imakhazikika kuti isatembenuke, ndipo yapano imakhala yamphamvu. Panthawi imeneyi, mphamvu ya rotor ndi yotsekedwa. General AC motors, kuphatikiza ma frequency modulation motors, saloledwa kuyimitsa.Malinga ndi mawonekedwe akunja amtundu wa mota ya AC, mota ya AC ikatsekedwa, "panthawi yosokoneza" imapangidwa kuti iwotche mota.
Mphamvu zokhoma ndi zoyambira ndizofanana, koma kutalika kwa injini yoyambira pano ndi yokhoma-yozungulira ndi yosiyana. Mtengo wokwanira wazomwe zimayambira pano umawoneka mkati mwa 0.025 injini ikayatsidwa, ndipo imawola kwambiri ndikupita kwa nthawi. , liwiro la kuwonongeka likugwirizana ndi nthawi yokhazikika ya injini; pomwe magetsi otsekeka a injini samawola ndi nthawi, koma amakhalabe osasintha.
Kuchokera pakuwunika kwa mota, titha kuzigawa m'magawo atatu: kuyambira, kuvotera ntchito ndi kutseka. Njira yoyambira imatanthawuza njira yosinthira rotor kuchoka ku static kupita ku liwiro la liwiro pomwe mota yapatsidwa mphamvu.
Za injini yoyambira pano
Zomwe zimayambira ndizomwe zimayenderana ndi kusintha kwa rotor kuchokera kumalo osasunthika kupita kumalo othamanga panthawi yomwe galimotoyo imapatsidwa mphamvu pansi pa mphamvu yamagetsi. Ndi ndondomeko ya kusintha kayendedwe ka galimoto rotor, ndiko kuti, kusintha inertia wa rotor, kotero lolingana panopa adzakhala ndi lalikulu.Mukayamba mwachindunji, mphamvu yoyambira ya injini nthawi zambiri imakhala nthawi 5 mpaka 7 kuposa momwe idavotera.Ngati mphamvu yoyambira ya injiniyo ndi yayikulu kwambiri, izi zitha kukhala ndi vuto lalikulu pagulu lamagetsi ndi gridi yamagetsi. Chifukwa chake, pama motors akulu ndi apakatikati, zoyambira zimangokhala pafupifupi 2 nthawi zomwe zidavotera pano poyambira mofewa. Kuwongolera kosalekeza kwa makina owongolera magalimoto ndi njira zingapo zoyambira monga kusinthira pafupipafupi komanso kutsika pang'ono zathetsa vutoli.
About motor stall current
Kunena zowona, zitha kumveka kuti chotchinga chotsekeka chapano ndichomwe chimayezedwa pomwe rotor imayima, ndipo rotor yotsekedwa ndi mota ndi pomwe mota imatulutsa torque pomwe liwiro limakhala zero, lomwe nthawi zambiri limakhala lopangidwa kapena lochita kupanga.
Motor ikadzaza, makina oyendetsedwa amalephera, mayendedwe amawonongeka, ndipo mota imalephera kwambiri, injiniyo imatha kulephera kuzungulira.injini ikatsekedwa, mphamvu yake imakhala yotsika kwambiri, ndipo makina ozungulira okhoma amakhala okulirapo, ndipo mafunde amoto amatha kuwotchedwa kwa nthawi yayitali.Komabe, pofuna kuyesa machitidwe ena a injini, m'pofunika kuyesa mayeso a galimoto, omwe amachitidwa muyeso la mtundu ndi kuyesa kwa injini.
Mayeso okhoma-rotor makamaka kuyeza zokhoma-rotor pano, mtengo wa torque wokhoma komanso kutayika kwa rotor yokhoma pamagetsi ovotera. Kupyolera mu kusanthula kwa zokhoma-rotor panopa ndi gawo la magawo atatu, zikhoza kusonyeza stator ndi rotor windings ya galimoto, komanso stator ndi rotor. Kumveka kwa maginito opangidwa ndi maginito ndi zovuta zina.
Pakuyesa kwamtundu wa mota, pali ma voliyumu ambiri omwe amayezedwa ndi mayeso okhoma-rotor. injini ikayesedwa pafakitale, gawo lamagetsi lidzasankhidwa kuti liyezedwe. Nthawi zambiri, voteji yoyezetsa imasankhidwa molingana ndi gawo limodzi mwa magawo anayi mpaka gawo limodzi mwa magawo asanu a magetsi ovotera agalimoto, monga Pamene voteji yoyezera ndi 220V, 60V imasankhidwa mofanana ngati voteji yoyesera, ndipo pamene voteji yovotera ndi 380V, 100V imasankhidwa ngati magetsi oyesera.
