Chifukwa chiyani chiwonjezeko chapano chikatha kukonzedwa kwa mafunde amoto?

Kupatula makamaka ma motors ang'onoang'ono, ma windings ambiri amafunikira kuviika ndi kuyanika kuti awonetsetse kuti ma windings amoto amawongolera ndipo nthawi yomweyo amachepetsa kuwonongeka kwa ma windings pamene galimoto ikudutsa pochiritsa ma windings.

Komabe, vuto lamagetsi losasinthika likachitika m'makona a injini, ma windings ayenera kukonzedwanso, ndipo ma windings oyambirira amachotsedwa. Nthawi zambiri, ma windings amachotsedwa ndi kutenthedwa, makamaka m'malo ogulitsa magalimoto. , ndi njira yotchuka kwambiri. Panthawi yoyaka moto, chitsulo chachitsulo chidzatenthedwa pamodzi, ndipo mapepala achitsulo omwe amakhomeredwa adzakhala oxidized, omwe ali ofanana ndi kutalika kwa injini yapakati kukhala yaying'ono komanso kuchepa kwa maginito a chitsulo pakati pazitsulo, zomwe zimatsogolera mwachindunji Kusanyamula katundu wa injini kumakhala kokulirapo, ndipo kuchuluka kwaposachedwa kumawonjezekanso kwambiri pazovuta kwambiri.

Pofuna kupewa vutoli, mbali imodzi, njira zimatengedwa popanga injini kuti zitsimikizire mtundu komanso kudalirika kwa ma windings amoto. Kumbali inayi, ma windings amachotsedwa m'njira zina pamene ma windings amakonzedwa. Uwu ndi muyeso wotengedwa ndi malo ogulitsa ambiri okhazikika. Ndikofunikiranso pazofunikira zoteteza chilengedwe.

Nthawi zambiri, zimatengera mphamvu ya injini.Kusanyamula katundu kumagalimoto ang'onoang'ono kumatha kufika 60% ya omwe adavotera, kapena kupitilira apo.Kusanyamula katundu kumagalimoto akulu akulu nthawi zambiri kumakhala pafupifupi 25% yokha yamagetsi omwe adavotera.

Ubale pakati pa zoyambira zamakono ndi zachizolowezi zogwira ntchito zamagalimoto agawo atatu.Kuyambira kwachindunji ndi nthawi 5-7, kutsika kwamagetsi kumayambira nthawi 3-5, ndipo magawo atatu amagetsi apano ndi pafupifupi nthawi 7.Single-gawo motors ndi pafupifupi 8 nthawi.

Pamene injini ya asynchronous ikuyenda popanda katundu, yomwe imayenda pamtunda wa magawo atatu a stator imatchedwa no-load current.Zambiri zopanda katundu zimagwiritsidwa ntchito popanga maginito ozungulira, omwe amatchedwa no-load excitation current, yomwe ndi gawo lokhazikika la palibe katundu wamakono.Palinso kagawo kakang'ono kamene kalibe katundu komwe amagwiritsidwa ntchito kuti awononge mphamvu zosiyanasiyana pamene galimoto ikuyenda popanda katundu. Gawoli ndi gawo logwira ntchito laposachedwa, ndipo limatha kunyalanyazidwa chifukwa limakhala ndi gawo laling'ono.Choncho, palibe katundu panopa akhoza kuonedwa ngati reactive panopa.

Kuchokera pamalingaliro awa, ang'onoang'ono ndi abwino, kotero kuti mphamvu ya galimotoyo ipitirire bwino, yomwe ndi yabwino kwa magetsi ku gridi.Ngati palibe katundu wamakono ndi waukulu, popeza kondakitala wonyamula malo a stator mapiringidzo ndi wotsimikizika ndipo panopa kuloledwa kudutsa ndi wotsimikizika, yogwira panopa kuloledwa kuyenda kudzera kondakitala akhoza kuchepetsedwa, ndi katundu kuti. injini ikhoza kuyendetsa idzachepetsedwa. Pamene kutulutsa kwa injini kumachepetsedwa ndipo katunduyo ndi waukulu kwambiri, ma windings amakonda kutentha.

Komabe, palibe katundu wapano sangakhale wocheperako, apo ayi zitha kukhudza zina zamagalimoto.Nthawi zambiri, ma mota ang'onoang'ono osanyamula katundu amakhala pafupifupi 30% mpaka 70% ya ma motors omwe adavotera, ndipo ma motors akulu ndi apakatikati omwe alibe katundu ndi pafupifupi 20% mpaka 40% yamagetsi omwe adavotera.Mphamvu yeniyeni yosanyamula katundu ya injini inayake nthawi zambiri sichimalembedwa pa dzina la injiniyo kapena buku lazinthu.Koma akatswiri amagetsi nthawi zambiri amafunika kudziwa kuti mtengo wake ndi chiyani, ndikugwiritsa ntchito mtengowu kuti aweruze ubwino wa kukonza galimoto komanso ngati angagwiritsidwe ntchito.

Chiyerekezo chosavuta cha injini yapanthawiyo yopanda katundu: gawani mphamvu ndi mtengo wamagetsi, ndikuchulukitsa quotient yake ndi zisanu ndi chimodzi kugawidwa ndi khumi.
