Kodi pali kusiyana kotani pakati pa single-phase ndi atatu-phase motors?

Wogwiritsa ntchito netizen adapereka kufotokozera kofananiza ndi kusanthulaya magawo atatu a motor ya gawo limodzi iyenera kuchitika.Poyankha funso la netizen, tikufanizira ndikusanthula ziwirizi kuchokera m'mbali zotsatirazi.

Monga momwe dzinalo likusonyezera, pali waya wagawo limodzi lokha la magetsi a gawo limodzi, ndipo waya wake umapangidwa ndi waya wamoyo ndi waya wosalowerera; magetsi a magawo atatu ali ndi mawaya atatu, ndipo mawaya ake ndi mawaya atatu-gawo anayi, ndiko kuti, mawaya atatu amoyo ndi waya wina wosalowerera.Mutha kusintha waya wamoyo ndi waya wosalowerera kuchokera pamzere wa magawo atatu kukhala magetsi agawo limodzi.Mu mzere wamagetsi, magetsi onse a magawo atatu amalowa m'malo amagetsi, ndiyeno amasinthidwa kukhala gawo limodzi kapena magawo atatu amagetsi malinga ndi ubale weniweni wa katundu ndi ntchito yeniyeni.

Mapiritsi a stator a magawo atatu a AC induction motor amapangidwa ndi magawo atatu omwe magawo ake atatu amasiyana ndi madigiri amagetsi a 120 mumlengalenga. Chochitika chakuthupi chomwe kupanga mizere yodula maginito pakati pa mizere kumagwira ntchito.Pamene atatu gawo stator mapiringidzo a galimoto chikugwirizana ndi magawo atatu symmetrical alternating panopa, wozungulira maginito adzakhala kwaiye, ndi kasinthasintha maginito adzadula ozungulira yozungulira.Chifukwa chake, mphamvu yamagetsi imapangidwa munjira yotsekeka yozungulira, ndipo woyendetsa wonyamula pakali pano apanga mphamvu yamagetsi yamagetsi mothandizidwa ndi maginito ozungulira a stator, potero amapanga torque yamagetsi pa shaft yamagalimoto, kuyendetsa galimoto kuti itembenuke, ndikuwongolera komwe kumazungulira ndi komwe kumazungulira maginito. yemweyo.

Kwa ma motors a single-gawo, mafunde a stator nthawi zambiri amakhala ndi mafunde akulu komanso mafunde achiwiri. Malinga ndi magulu osiyanasiyana a mndandanda, ntchito za windings yachiwiri sizili zofanana.Timatengera capacitor-started single-phase motor monga chitsanzo cha AC.Kuti injini yagawo limodzi ikhale yozungulira yokha, titha kuwonjezera mafunde oyambira ku stator. Kumayambiriro koyambira ndi madigiri a 90 mosiyana ndi mafunde akulu mumlengalenga. Kusiyana kwa gawo ndi pafupifupi madigiri 90, omwe amatchedwa gawo-kugawanika kapena gawo-kusintha mfundo.Mwa njira iyi, mafunde awiri omwe ali ndi kusiyana kwa madigiri 90 mu nthawi amadutsa muzitsulo ziwiri zosiyana za madigiri 90 mumlengalenga, zomwe zimapanga (gawo ziwiri) zozungulira maginito mumlengalenga. Pansi pa mphamvu ya maginito yozungulira iyi, rotor imatha kungoyambira. Pambuyo poyambira, liwiro likafika pamlingo wina, mafunde oyambira amachotsedwa pogwiritsa ntchito chosinthira cha centrifugal kapena chida china chowongolera chomwe chimayikidwa pa rotor, ndipo mafunde akulu okhawo amagwira ntchito nthawi zonse.Chifukwa chake, kuwongolera koyambira kumatha kupangidwa kukhala njira yanthawi yochepa yogwirira ntchito.

Poganizira za kuchepa kwa magetsi m'malo osiyanasiyana, ma mota agawo limodzi amagwiritsidwa ntchito kwambiri m'malo okhala, pomwe ma mota agawo atatu amagwiritsidwa ntchito kwambiri m'mafakitale.
