110V 220V 380V AC MOTOR

Akwai manyan dalilai guda biyu:

1. Yafi daga juzu'i na rotor: lokacin da induction motor ke cikin yanayin tsayawa, daga ra'ayi na electromagnetic, kamar yadda na'urar ta atomatik, iskar motar da aka haɗa zuwa bangaren samar da wutar lantarki daidai yake da iskar farko na iskar wutar lantarki. transformer, da kuma rotor winding a rufaffiyar da'irar daidai yake da na biyu na na'ura mai ba da hanya tsakanin hanyoyin sadarwa.Babu haɗin lantarki tsakanin iskar stator da na'ura mai juyi, amma haɗin maganadisu kawai.Magnetic jujjuyawar yana samar da rufaffiyar madauki ta hanyar stator, tazarar iska da madaidaicin rotor.Lokacin da aka kunna na'ura mai juyi saboda rashin aiki, filin maganadisu mai jujjuya yana yanke iska mai jujjuyawa a matsakaicin saurin yanke (gudun daidaitawa), yana haifar da iska mai jujjuyawa don haifar da mafi girman ƙarfin lantarki.Don haka, babban motsi yana gudana a cikin madubin rotor, wanda ke haifar da kuzarin maganadisu don daidaita filin maganadisu na stator, kamar yadda maɗaukakin maganadisu na biyu na na'ura mai canzawa zai kashe babban juzu'in maganadisu.

Domin kula da asalin magnetic flux wanda ya dace da ƙarfin wutar lantarki a wancan lokacin, stator yana ƙaruwa ta atomatik.A wannan lokacin, rotor halin yanzu yana da girma sosai, don haka ma'aunin stator shima yana ƙaruwa sosai, har zuwa sau 4 ~ 7 na halin yanzu, wanda shine dalilin babban lokacin farawa.

Yayin da motsin motar ke ƙaruwa, saurin da filin maganadisu na stator ya yanke na'ura mai ba da hanya tsakanin hanyoyin sadarwa yana raguwa, ƙarfin wutar lantarki da aka jawo a cikin na'ura mai ba da hanya tsakanin hanyoyin sadarwa yana raguwa, kuma halin yanzu a cikin na'urar rotor shima yana raguwa.Sabili da haka, ɓangaren stator current da ake amfani da shi don magance tasirin magnetic flux da ke haifar da rotor current shima yana raguwa, don haka stator current yana canzawa daga babba zuwa ƙarami har sai ya zama al'ada.

2. Yawanci daga yanayin stator: A cewar dokar Ohm, lokacin da ƙarfin lantarki ya zama daidai, ƙananan ƙimar impedance, mafi girma a halin yanzu.A lokacin da aka fara hawan mota, rashin ƙarfi a cikin madauki na yanzu shine kawai juriya na iskar iska, wanda gabaɗaya an yi shi da madubi na jan karfe, don haka ƙimar juriya tayi ƙanƙanta, in ba haka ba na yanzu zai zama babba sosai.

A lokacin farawa, saboda tasirin shigar da maganadisu, ƙimar amsawa a cikin madauki yana ƙaruwa sannu a hankali, ta yadda ƙimar halin yanzu tana raguwa a hankali a hankali har sai ta zama tsayayye.
