Lokacin da aka rage ƙarfin lantarki, motar, a matsayin ainihin na'urar motar lantarki, yana fuskantar jerin canje-canje masu mahimmanci

Lokacin da aka rage ƙarfin lantarki, motar, a matsayin ainihin na'urar motar lantarki, yana fuskantar jerin canje-canje masu mahimmanci. Mai zuwa shine cikakken bincike na waɗannan canje-canje, wanda aka tsara don taimakawa mafi kyawun fahimtar tasirin rage ƙarfin lantarki akan aikin mota da yanayin aiki.

一, Canje-canje na Yanzu
Bayanin ƙa'idar: Bisa ga dokar Ohm, dangantakar dake tsakanin I na yanzu, ƙarfin lantarki U da juriya R shine I = U / R. A cikin injunan lantarki, juriya R (mafi yawan juriya da juriya na rotor) yawanci baya canzawa sosai, don haka rage ƙarfin lantarki U zai kai tsaye kai tsaye zuwa haɓaka I. Ga nau'ikan injin lantarki daban-daban, canjin na yanzu zai kasance daidai da na juriya na stator. Don nau'ikan injina daban-daban, takamaiman bayyanar canje-canje na yanzu na iya bambanta.

Takamaiman aiki:
Motocin DC: Motocin DC marasa goga (BLDC) da gogaggun injuna na DC suna samun ƙaruwa mai yawa a halin yanzu lokacin da aka rage ƙarfin wutar lantarki idan nauyin ya kasance koyaushe. Wannan saboda motar tana buƙatar ƙarin halin yanzu don kula da fitarwa na asali.

Motocin AC: Don injinan asynchronous, kodayake motar ta atomatik tana rage saurinsa don dacewa da kaya lokacin da aka rage ƙarfin lantarki, na yanzu na iya tashi idan aka kwatanta da canjin nauyi ko fiye da sauri. Dangane da injin da ke aiki tare, idan nauyin ya kasance baya canzawa lokacin da aka saukar da wutar lantarki, na yanzu ba zai canza sosai a ka'ida ba, amma idan nauyin ya karu, na yanzu kuma zai karu.

二、 juzu'i da canjin gudu

Canjin juzu'i: Rage wutar lantarki yawanci yana haifar da raguwar juzu'in motsi. Wannan shi ne saboda karfin wutar lantarki ya yi daidai da abin da ake samu a halin yanzu da kuma jujjuyawa, kuma lokacin da aka rage karfin wutar lantarki, duk da cewa na yanzu yana karuwa, juzu'in na iya raguwa saboda rashin wutar lantarki, yana haifar da raguwar karfin gaba daya. Duk da haka, a wasu lokuta, kamar a cikin motocin DC, idan halin yanzu ya karu sosai, zai iya ramawa ga raguwar motsi zuwa wani matsayi, kiyaye karfin wutar lantarki mai inganci.

Canjin sauri: Don injinan AC, musamman asynchronous da injuna, rage ƙarfin lantarki zai haifar da raguwar saurin gudu kai tsaye. Domin gudun motar yana da alaƙa da yawan wutar lantarki da kuma adadin nau'ikan sandar sandar mota, kuma rage ƙarfin wutar lantarki zai yi tasiri ga ƙarfin filin lantarki na injin, wanda hakan yana rage saurin gudu. Ga motocin DC, saurin yana daidai da ƙarfin lantarki, don haka saurin zai ragu daidai lokacin da ƙarfin lantarki ya ragu.

三, inganci da zafi
Ƙarƙashin inganci: ƙananan ƙarfin lantarki zai haifar da ƙananan ƙarfin mota. Saboda motar da ke cikin ƙananan ƙarfin lantarki aiki, yana buƙatar ƙarin halin yanzu don kula da ikon fitarwa, kuma karuwa a halin yanzu zai ƙara asarar jan ƙarfe na motar da asarar ƙarfe, don haka rage yawan aiki.
Ƙarfafa haɓakar zafi: Saboda haɓakar halin yanzu da raguwar inganci, injina suna haifar da ƙarin zafi yayin aiki. Wannan ba kawai yana hanzarta tsufa da lalacewa na motar ba, har ma yana iya haifar da kunna na'urar kariya ta wuce gona da iri, wanda ke haifar da rufe motar.

四, tasiri akan rayuwar motar
Yin aiki na dogon lokaci a ƙarƙashin ƙarancin ƙarfin lantarki ko ƙarancin wutar lantarki zai rage rayuwar sabis ɗin motar da gaske. Saboda raguwar wutar lantarki da ke haifar da karuwa a halin yanzu, sauye-sauyen juzu'i, raguwar saurin gudu da raguwar inganci da sauran batutuwa zasu haifar da lalacewa ga tsarin ciki da aikin lantarki na motar. Bugu da ƙari, haɓakar haɓakar zafi zai kuma hanzarta aiwatar da tsufa na kayan aikin motsa jiki.

五, Countermeasures
Domin rage tasirin rage wutar lantarki akan motar, ana iya ɗaukar matakai masu zuwa:
Inganta tsarin samar da wutar lantarki: tabbatar da cewa ƙarfin wutar lantarki na grid ɗin wutar lantarki ya tabbata, don guje wa tasirin jujjuyawar wutar lantarki akan motar.
Zaɓin injunan da suka dace: a cikin ƙira da zaɓin sauye-sauyen ƙarfin lantarki yi la'akari da cikakken abubuwan zaɓi na injina tare da daidaitawar ƙarfin lantarki mai yawa.
Shigar da ma'aunin ƙarfin lantarki: shigar da ma'aunin ƙarfin lantarki ko mai kayyade ƙarfin lantarki a shigar da motar don kula da kwanciyar hankali na ƙarfin lantarki.

Ƙarfafa gyare-gyare: dubawa na yau da kullum da kuma kula da motar don ganowa da magance matsalolin da za a iya fuskanta a kan lokaci don kara tsawon rayuwar motar.
A taƙaice, tasirin raguwar ƙarfin lantarki a kan motar yana da nau'i-nau'i daban-daban, ciki har da canje-canje na yau da kullum, sauye-sauye da sauri da sauri, inganci da matsalolin zafi da tasirin rayuwar motar. Don haka, a aikace-aikace masu amfani suna buƙatar ɗaukar ingantattun matakai don rage waɗannan tasirin don tabbatar da aminci da kwanciyar hankali na injin.
