Kodi kuchepa kwa mphamvu yamagetsi kumakhudza bwanji injini?

I. Kusintha kwa Pakali pano
Malinga ndi lamulo la Ohm, ubale pakati pa I yamagetsi, voltage U, ndi kukana R ndi I = U/R. Mu ma mota, 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, mawonekedwe enieni a kusinthasintha kwamagetsi amatha kusiyana.

Mawonetseredwe enieni:
Mota ya DC: Kwa ma mota a DC opanda maburashi (BLDC) ndi ma mota a DC opangidwa ndi maburashi, magetsi akatsika ndipo katunduyo ukakhalabe wosasintha, mphamvu yamagetsi imawonjezeka kwambiri. Izi zili choncho chifukwa mota imafuna mphamvu yamagetsi yambiri kuti isunge mphamvu yamagetsi yoyambirira.
Mota ya AC: Pa ma mota osasinthasintha, ngakhale kuti motayo imachepetsa liwiro lake kuti igwirizane ndi katundu pamene magetsi atsika, pamene katunduyo ndi wolemera kapena akusintha mofulumira, mphamvu yamagetsi imatha kukwerabe. Pa ma mota osinthasintha, mphamvu yamagetsi ikatsika ndipo katunduyo akapitirirabe kusintha, mwachiphunzitso kusintha kwa mphamvu yamagetsi sikofunikira. Komabe, ngati katunduyo akwera, mphamvu yamagetsi nayonso idzakwera.

II. Kusintha kwa Mphamvu ndi Liwiro
Kusintha kwa Mphamvu ya Mphamvu: Kuchepa kwa mphamvu yamagetsi nthawi zambiri kumabweretsa kuchepa kwa mphamvu yamagetsi ya injini. Popeza mphamvu yamagetsi imagwirizana mwachindunji ndi zomwe zimachitika chifukwa cha mphamvu yamagetsi ndi mphamvu yamagetsi, mphamvu yamagetsi ikatsika, ngakhale mphamvu yamagetsi ikakwera, mphamvu yamagetsi imatha kuchepa chifukwa cha mphamvu yamagetsi yosakwanira, zomwe zimapangitsa kuti mphamvu yamagetsi ichepe. Komabe, nthawi zina, monga ma DC motors, ngati mphamvu yamagetsi ikakwera mokwanira, ikhoza kubweza kuchepa kwa mphamvu yamagetsi yamagetsi pamlingo wina, ndikusunga mphamvu yamagetsi yokhazikika.
Kusintha kwa Liwiro: Kwa ma mota a AC, makamaka ma mota osasinthasintha komanso ogwirizana, kuchepa kwa magetsi kumapangitsa kuti liwiro lichepe. Izi zili choncho chifukwa liwiro la mota limagwirizana ndi kuchuluka kwa magetsi ndi kuchuluka kwa ma poles a mota, ndipo kuchepa kwa magetsi kumakhudza mphamvu yamagetsi ya mota, motero kuchepetsa liwiro. Kwa ma mota a DC, liwiro limagwirizana mwachindunji ndi magetsi, kotero kuchepa kwa magetsi kumapangitsa kuti liwiro lichepe moyenerera.

III. Kugwira Ntchito Moyenera ndi Kupanga Kutentha
Kuchepa kwa Mphamvu: Kuchepa kwa mphamvu yamagetsi kudzapangitsa kuti mphamvu ya injini ichepe. Pamene injini ikugwira ntchito pa mphamvu yamagetsi yochepa, imafunika mphamvu yamagetsi yambiri kuti isunge mphamvu yotulutsa. Kuwonjezeka kwa mphamvu yamagetsi kudzapangitsa kuti mkuwa utayike komanso chitsulo cha injini chitayike, motero kuchepetsa mphamvu yonse.
Kuwonjezeka kwa Kutentha: Chifukwa cha kuwonjezeka kwa mphamvu yamagetsi komanso kuchepa kwa magwiridwe antchito, mota imapanga kutentha kwambiri ikagwira ntchito. Izi sizimangofulumizitsa ukalamba ndi kuwonongeka kwa mota komanso zingayambitse kuyatsa kwa chipangizo choteteza kutentha kwambiri, zomwe zimapangitsa kuti mota iyime.

IV. Kukhudza Nthawi Yogwira Ntchito ya Galimoto
Kuyendetsa mota pamalo opanda mphamvu kapena mphamvu yochepa kwa nthawi yayitali kudzafupikitsa kwambiri moyo wake. Izi zili choncho chifukwa kuchepa kwa mphamvu kumapangitsa kuti mphamvu yamagetsi ikwere, mphamvu yamagetsi isinthe, liwiro lichepe, komanso mphamvu ichepe, zomwe zonsezi zingawononge kapangidwe ka mkati ndi magwiridwe antchito amagetsi a mota. Kuphatikiza apo, kuwonjezeka kwa kutentha kudzathandizira kukalamba kwa zinthu zotetezera kutentha za mota.

V. Njira Zothanirana ndi Mavuto
Pofuna kuchepetsa mphamvu ya magetsi pa injini, njira zotsatirazi zitha kuchitidwa:
Konzani bwino njira yoperekera magetsi: Onetsetsani kuti magetsi a gridi yamagetsi ndi olimba ndipo pewani kusinthasintha kwa magetsi komwe kungayambitse mavuto pa injini.
Sankhani ma mota oyenera: Mukapanga ndi kusankha, ganizirani mokwanira zinthu zomwe zimapangitsa kuti magetsi asinthe ndipo sankhani ma mota omwe ali ndi mphamvu zambiri zosinthira magetsi.
Ikani zokhazikika pamagetsi: Onjezani zokhazikika pamagetsi kapena zowongolera kumapeto kwa injini kuti musunge kukhazikika kwamagetsi.
Limbikitsani kukonza ndi kusamalira: Yendani ndi kusamalira injini nthawi zonse kuti muzindikire ndi kuthetsa mavuto omwe angakhalepo, motero muwonjezere nthawi yogwira ntchito ya injiniyo.
Pomaliza, mphamvu ya kuchepetsa mphamvu yamagetsi pa mota ndi yambiri, kuphatikizapo kusintha kwa mphamvu yamagetsi, mphamvu yamagetsi ndi liwiro, mphamvu yamagetsi ndi kupanga kutentha, komanso momwe injini imakhudzira moyo wake. Chifukwa chake, pakugwiritsa ntchito bwino, njira zogwira mtima ziyenera kutengedwa kuti zichepetse zotsatirazi ndikuwonetsetsa kuti mota ikugwira ntchito bwino komanso motetezeka.
