AC: chiwembu. Motors magetsi ndi AC

M'nkhani limeneli muphunzira zimene magetsi AC, taganizirani chipangizo awo, mfundo opaleshoni, dera ntchito. Tikumbukenso kuti lero mu makampani peresenti kuposa 95 a injini zonse ntchito nkhani makina asynchronous. Anailandira ambiri chifukwa chakuti iwo ndi mkulu zodalirika, iwo akhoza kukhala aatali kwambiri chifukwa maintainability ake.

Mfundo ntchito Motors kupatsidwa ulemu

Kumvetsa mmene galimoto, mukhoza kuchititsa kuyesera pang'ono. Kumene, muyenera kukhala ndi chida chapadera. Ikani maginito mu mawonekedwe a horseshoe kuti anali anayambika ndi chogwirira. Monga mukudziwa, maginito ali mitengo iwiri. Pakati pa iwo ndi zofunika kukonza yamphamvu ndi zopangidwa ndi mkuwa. M'njira kuti momasuka atembenuza padziko nguli. Tsopano kuyesa yokha. Yambani sapota maginito, zimenezi zimapangitsa munda zokwawa. Mkati yamphamvu mkuwa anayamba uka mafunde zimakochezapo, amene kutsutsa munda maginito.

Chifukwa, ndi yamphamvu mkuwa akuyamba atembenuza mu njira imene ikuyenda okhazikika maginito. Komanso, penapake m'munsi liwiro. Chifukwa cha ichi - pa liwiro monga mizere ya mphamvu asiye kusokoneza ndi maginito kumunda. The maginito imazungulira synchronously. Koma liwiro kayendedwe ka maginito Nonsynchronous. Ndipo ngati pang'ono odulidwa tanthauzo, asynchronous. Choncho dzina la makina magetsi - kupatsidwa ulemu galimoto. Ngati akhakula, ndiye galimoto dera AC pafupifupi mofanana mu kuyesera pamwambapa. Only ndi maginito analengedwa ndi stator kumulowetsa.

Motors DC

Iwo osiyana ku AC Motors kupatsidwa ulemu. Choyamba, payenera stator imodzi kapena ziwiri kumulowetsa. Chachiwiri, njira ya kusintha ozungulira liwiro ndi yosiyana. Koma ozungulira kasinthasintha malangizo zitasintha ya kusintha polarity (mu makina asynchronous mains gawo kusintha malo). Change liwiro la mota DC ozungulira n'zotheka, ngati kuchuluka kapena kuchepa voteji amaperekedwa kwa stator kumulowetsa.

DC galimoto sungathe kugwira ntchito popanda malemeredwe kumulowetsa, limene lili ozungulira lapansi. voteji HIV kumachitika mwa khamu burashi. Ichi ndi chinthu kwambiri wosadalirika kulengedwa. Maburashi anapangidwa kuchokera graphite, kenako achotsa, zikubweretsa kulephera kwa galimoto, ndi wofunika kukonza. Onani kuti AC ndi DC Motors magetsi ndi zinthu zomwezo, koma nyumba zawo zili zosiyana kwambiri.

Kapangidwe ka galimoto magetsi

Ngati wina aliyense makina sanali malo amodzi magetsi, ndi galimoto asynchronous ali mbali ziwiri zazikulu - ndi stator ndi ozungulira. Amafotokozera woyamba pa izo anaika windings atatu ogwirizana mu ndondomeko zina. The ozungulira ndi makina, kapangidwe amatchedwa "gologolo khola". Chifukwa dzina ili ndi dongosolo mkati ndi zofanana kwambiri ndi gudumu ndi gologolo wa.

Otsiriza, kumene, osati za galimoto. wokhudzana ndi ozungulira wopangidwa ndi chimakwirira awiri, wokwera pa stator lapansi. Iwo mayendedwe kuti atsogolere kasinthasintha. Pa kumbuyo kwa galimoto impeller anaika. Mothandizidwa ndi yozizira ndi makina magetsi ikuchitika. Pa stator anapangidwa nthiti kuti kusintha kutentha kusintha. Choncho Motors AC ndi opareshoni mu yachibadwa matenthedwe ulamuliro.

The stator ya galimoto kupatsidwa ulemu

Tikumbukenso kuti stator mitengo yonyamulira ya Motors ano asynchronous asanawonetseredwebe. Kunena mwachidule, lonse mkati pamwamba mwangwiro yosalala. Pofuna kuchepetsa zimakochezapo imfa panopa, pakati asonkha wopyapyala kwambiri ngati chitsulo. mapepala awa ayandikira kwambiri koyenera mzake ndipo kenako ananamizira mu casing zitsulo. The stator ali grooves kwa kuika windings.

windings anapangidwa wa waya mkuwa. Kulumikiza iwo ali mu "nyenyezi" kapena "makona". Mu kumtunda kwa thupi ali ndi chishango yaing'ono, olekanitsidwa. Pali kulankhula ndi kugwirizana kwa kulumikiza windings. Ndipo inu mukhoza kugwirizana kumulowetsa ntchito jumpers anaika mu gulu la. chipangizo ndi AC galimoto chimathandiza kugwirizana mwamsanga windings mu chitsanzo ankafuna.

Ozungulira kupatsidwa ulemu galimoto

Ponena za iye anali wamng'ono kwambiri zikunenedwa. Iye amaoneka ngati khola gologolo. Kamangidwe ozungulira ndi anasonkhana ku wopyapyala zitsulo, komanso stator. The ozungulira mipata ndi kumulowetsa, koma angakhale mitundu yambiri. Zidalira pa gawo kapena gologolo-khola ozungulira. Ambiri ziwembu atsopano. Wandiweyani mkuwa ndodo anayikidwa mu grooves popanda chimateteza zakuthupi. Pa malekezero onse a ndodo ogwirizana ndi mphete mkuwa. Nthawi zina, mmalo mwa "gologolo khola" ntchito aloyi rotors.

Koma pali AC Motors ndi Motors kupulumuka mphete. Iwo anagwiritsa ntchito zochepa zambiri, makamaka kwa Motors magetsi, zomwe ndi mphamvu kwambiri. Nkhani yachiwiri, imene m'pofunika ntchito Motors kupulumuka mphete Motors magetsi - chilengedwe cha kwambiri khama pa nthawi Launch. Komabe, m'pofunika ntchito rheostat wapadera.

Njira kuyamba kupatsidwa ulemu galimoto

Thamanga AC asynchronous galimoto ndi yosavuta, inu basi kugwirizana stator windings mu zopezera atatu gawo. Kulumikiza wopangidwa ndi thandizo la contactors maginito. Chifukwa cha iwo, inu mukhoza pafupifupi automate chiyambi. Ngakhale n'zosiyana zikhoza kuchitika mosavuta kwambiri. Koma nthawi zina m'pofunika kuchepetsa voteji kuti umagwiritsidwa ntchito pa windings stator.

Izi zachitika pogwiritsa ntchito zithunzi kugwirizana ndi "makona". Mu ichi chiyambi-mmwamba ndi pamene windings olumikizidwa ku "nyenyezi". Ndi changu, kukwanilitsa zosowa kusinthana kwa "ankadziwana" dera pazipita kumulowetsa. Choncho pali kuchepetsa ankadya panopa pafupifupi katatu. Koma kudziwa kuti si stator akhoza kugwira bwino pamene chikugwirizana malinga chiwembu "makona".

ulamuliro liwiro

Makampani ndi moyo wa tsiku ndi tsiku kukhala converters kunadetsa otchuka pafupipafupi. Iwo akhoza kukhala pang'ono kayendedwe ka manja kusintha ozungulira kasinthasintha liwiro. Tikumbukenso kuti Motors AC ntchito molumikizana ndi converters pafupipafupi mu njira zambiri. Iwo amalola kuti kulipiritsa-konza ndi galimoto, si koyenera kuti ntchito actuators maginito. amazilamulira onse olumikizidwa kwa malo a pafupipafupi inverter. Zikhazikiko amakulolani kusintha nthawi ya mathamangitsidwe wa galimoto ozungulira, kuzileketsa izo, pamene osachepera ndi liwiro pazipita, komanso zina zambiri ntchito zoteteza.

Pomaliza

Tsopano inu mukudziwa momwe ntchito AC galimoto amapezeka. Ngakhale aphunzira kapangidwe wotchuka kwambiri wa galimoto kupatsidwa ulemu. Ndi yotsika mtengo zonse, amene anapereka pa msika. Komanso, chifukwa ntchito yachibadwa palibe kugwiritsa ntchito zipangizo zosiyanasiyana wothandiza. Makamaka, dimmers. Ndipo kokha ngati Komanso, monga Converter pafupipafupi, chingathandize ntchito kwa galimoto kupatsidwa ulemu, kukuza mphamvu yake kwambiri.
