Pamene magetsi achepa, mota, monga chipangizo chachikulu cha drive yamagetsi, imadutsa mu kusintha kwakukulu kotsatizana

Pamene magetsi achepa, mota, monga chipangizo chachikulu cha magetsi, imadutsa mu kusintha kwakukulu. Zotsatirazi ndi kusanthula mwatsatanetsatane kwa kusinthaku, komwe kwapangidwa kuti kuthandize kumvetsetsa bwino momwe kuchepetsa magetsi kumakhudzira magwiridwe antchito a mota ndi momwe imagwirira ntchito.

一, Kusintha Kwamakono
Kufotokozera mfundoyi: Malinga ndi lamulo la Ohm, ubale pakati pa I yamagetsi, voltage U ndi kukana R ndi I=U/R. Mu ma mota amagetsi, kukana R (makamaka kukana kwa stator ndi kukana kwa rotor) nthawi zambiri sikusintha kwambiri, kotero kuchepa kwa voltage U kudzatsogolera mwachindunji kuwonjezeka kwa I yamagetsi. Pa mitundu yosiyanasiyana ya ma mota amagetsi, kusintha kwamagetsi kudzakhala kofanana ndi kwa kukana kwa stator. Pa mitundu yosiyanasiyana ya ma mota, mawonekedwe enieni a kusintha kwamagetsi amatha kusiyana.

Magwiridwe antchito enieni:
Ma mota a DC: Ma mota a DC opanda maburashi (BLDC) ndi ma mota a DC opangidwa ndi maburashi amakumana ndi kuwonjezeka kwakukulu kwa mphamvu yamagetsi pamene magetsi achepa ngati katunduyo ukukhalabe wokhazikika. Izi zili choncho chifukwa mota imafuna mphamvu yamagetsi yambiri kuti isunge mphamvu yamagetsi yoyambirira.

Ma mota a AC: Pa ma mota a asynchronous, ngakhale kuti mota imachepetsa liwiro lake lokha kuti igwirizane ndi katundu pamene magetsi achepa, mphamvu yamagetsi ikhoza kukwerabe ngati katundu wolemera kapena wosintha mofulumira. Ponena za mota ya synchronous, ngati katunduyo sunasinthe pamene magetsi atsika, mphamvu yamagetsi sidzasintha kwambiri mwa chiphunzitso, koma ngati katunduyo awonjezeka, mphamvu yamagetsi nayonso idzawonjezeka.

Kusintha kwa torque ndi liwiro

Kusintha kwa mphamvu: Kuchepetsa mphamvu yamagetsi nthawi zambiri kumabweretsa kuchepa kwa mphamvu yamagetsi. Izi zili choncho chifukwa mphamvu yamagetsi imagwirizana ndi zomwe zimachitika chifukwa cha mphamvu yamagetsi ndi mphamvu yamagetsi, ndipo mphamvu yamagetsi ikatsika, ngakhale mphamvu yamagetsi ikakwera, mphamvu yamagetsi imatha kuchepa chifukwa cha kusowa kwa mphamvu yamagetsi, zomwe zimapangitsa kuti mphamvu yamagetsi yonse ichepe. Komabe, nthawi zina, monga ma DC motors, ngati mphamvu yamagetsi yawonjezeka mokwanira, ikhoza kubweza kuchepa kwa mphamvu yamagetsi pamlingo wina, ndikusunga mphamvu yamagetsiyo kukhala yokhazikika.

Kusintha kwa liwiro: Kwa ma mota a AC, makamaka ma mota osasinthasintha komanso ogwirizana, kuchepa kwa magetsi kudzapangitsa kuti liwiro lichepe mwachindunji. Izi zili choncho chifukwa liwiro la mota limagwirizana ndi kuchuluka kwa magetsi ndi kuchuluka kwa ma mota awiriawiri, ndipo kuchepa kwa magetsi kudzakhudza mphamvu ya magetsi a mota, zomwe zimachepetsa liwiro. Kwa ma mota a DC, liwiro limakhala lofanana ndi magetsi, kotero liwiro lidzachepa moyenerera magetsi akachepa.

Mphamvu ndi kutentha
Kutsika kwa mphamvu: mphamvu yotsika imabweretsa kuchepa kwa mphamvu ya injini. Chifukwa chakuti injini yomwe ikugwira ntchito yamagetsi otsika imafunika mphamvu yowonjezera kuti isunge mphamvu yotulutsa, ndipo kuwonjezeka kwa mphamvu kudzawonjezera kutayika kwa mkuwa kwa injini ndi kutayika kwa chitsulo, motero kuchepetsa mphamvu yonse.
Kuchuluka kwa kutentha: Chifukwa cha kuchuluka kwa mphamvu yamagetsi komanso kuchepa kwa magwiridwe antchito, ma mota amapanga kutentha kwambiri panthawi yogwira ntchito. Izi sizimangofulumizitsa ukalamba ndi kuwonongeka kwa mota, komanso zingayambitse kuyatsa kwa chipangizo choteteza kutentha kwambiri, zomwe zimapangitsa kuti mota izime.

Mphamvu ya injini pa moyo wake
Kugwira ntchito kwa nthawi yayitali pansi pa mphamvu yamagetsi yosakhazikika kapena mphamvu yamagetsi yochepa kudzafupikitsa kwambiri moyo wa injini. Chifukwa kuchepa kwa mphamvu yamagetsi komwe kumachitika chifukwa cha kuwonjezeka kwa mphamvu yamagetsi, kusinthasintha kwa mphamvu yamagetsi, kuchepa kwa liwiro ndi kuchepetsa mphamvu ndi zina zidzawononga kapangidwe ka mkati ndi magwiridwe antchito amagetsi a injini. Kuphatikiza apo, kuwonjezeka kwa kutentha kudzathandizanso kuti zinthu zotetezera injini ziyambe kukalamba.

五、Kutsutsa
Pofuna kuchepetsa mphamvu ya kuchepetsa mphamvu ya magetsi pa injini, njira zotsatirazi zitha kuchitidwa:
Konzani bwino njira yoperekera magetsi: onetsetsani kuti magetsi a gridi yamagetsi ndi okhazikika, kuti mupewe kusinthasintha kwa magetsi pa mota.
Kusankha ma mota oyenera: popanga ndi kusankha kusinthasintha kwa magetsi, ganizirani zonse zomwe zimapangitsa kusankha ma mota okhala ndi mitundu yosiyanasiyana ya magetsi.
Ikani chokhazikitsa mphamvu yamagetsi: ikani chokhazikitsa mphamvu yamagetsi kapena chowongolera mphamvu yamagetsi pamalo olowera a injini kuti magetsi azikhala olimba.

Limbitsani kukonza: kuyang'anira ndi kusamalira mota nthawi zonse kuti mupeze ndikuthana ndi mavuto omwe angakhalepo nthawi yake kuti muwonjezere nthawi yogwira ntchito ya mota.
Mwachidule, mphamvu ya kuchepetsa mphamvu yamagetsi pa injini ili ndi mbali zambiri, kuphatikizapo kusintha kwa magetsi, kusintha kwa mphamvu yamagetsi ndi liwiro, mavuto ogwira ntchito bwino komanso kutentha komanso momwe moyo wa injini umakhudzira. Chifukwa chake, pakugwiritsa ntchito moyenera, pakufunika njira zothandiza kuchepetsa zotsatirazi kuti zitsimikizire kuti injiniyo ikugwira ntchito bwino komanso mokhazikika.
