Chimodzi mwazinthu zogwirira ntchito zamagalimoto - mtundu wa torque yamagalimoto ndi momwe zimagwirira ntchito

Torque ndiye mtundu woyambira wamakina otumizira makina osiyanasiyana ogwira ntchito, womwe umagwirizana kwambiri ndi mphamvu yogwirira ntchito, kugwiritsa ntchito mphamvu, mphamvu, moyo wogwira ntchito, komanso chitetezo chamakina amagetsi. Monga makina amagetsi wamba, torque ndi gawo lofunikira kwambiri pamagetsi amagetsi.

Zosiyanasiyana zogwirira ntchito zimakhala ndi zofunikira zosiyanasiyana pakuchita ma torque a mota, monga chilonda cha rotor motor, slip motor, wamba khola motor, frequency conversion control control motor, etc.

Kuyika kwa torque kwa mota ndikozungulira ponseponse, ndipo mawonekedwe osiyanasiyana amatengera mawonekedwe a torque ya mota. Makokedwe a mota makamaka amaphatikiza torque yayikulu, torque yocheperako ndi torque yoyambira, torque yoyambira ndi torque yocheperako imawonedwa kuti ikulimbana ndi kusintha kwamphamvu kukana kukana pamayendedwe oyambira, kuphatikiza nthawi yoyambira ndikuyambira pano, zomwe zimawonekera m'njira yofulumizitsa torque. Torque yayikulu nthawi zambiri imakhala chiwonetsero cha kuchuluka kwamphamvu pakugwira ntchito kwa mota.

Ma torque oyambira ndi chimodzi mwazofunikira zaukadaulo zoyezera momwe injini imayambira. Kukula kwa torque yoyambira, injiniyo imafulumizitsa mwachangu, ndiyofupikitsa njira yoyambira, ndipo imayambanso ndi katundu wolemetsa. Zonsezi zikuwonetsa ntchito yabwino yoyambira. M'malo mwake, ngati torque yoyambira ndi yaying'ono, kuyambika kumakhala kovuta, ndipo nthawi yoyambira ndi yayitali, kotero kuti kuwongolera kwagalimoto kumakhala kosavuta kutenthetsa, kapenanso sikungayambike, osasiya kunyamula katundu wolemera.

Maximum torque ndi chizindikiro chofunikira chaukadaulo kuyeza kuchuluka kwanthawi yayitali kwagalimoto. Kuchulukira kwa torque kumapangitsa kuti injiniyo ikhale ndi mphamvu yopirira mphamvu zamakina. Ngati galimotoyo yadzaza kwa nthawi yochepa pogwira ntchito ndi katundu, pamene torque yaikulu ya galimotoyo imakhala yochepa kusiyana ndi torque yolemetsa, galimotoyo imayima ndipo kuphulika kwa khola kudzachitika, zomwe nthawi zambiri timazitcha kulephera.

Ma torque ocheperako ndiye torque yocheperako panthawi yoyambira. Mtengo wocheperako wa torque wokhazikika wokhazikika pakati pa liwiro la zero ndi liwiro lofananira la mota pama frequency ovotera ndi voliyumu yovoteledwa. Ikakhala yocheperako kukana kwa torque m'malo ofananirako, liwiro la mota limayimilira m'malo osavomerezeka ndipo silingayambike.

Kutengera kuwunika komwe kuli pamwambapa, titha kunena kuti torque yayikulu ndiyomwe imagwira ntchito kwambiri pakukana kolemetsa panthawi yagalimoto, pomwe ma torque oyambira ndi torque yocheperako ndi ma torque pansi pamikhalidwe iwiri yoyambira.

Mitundu yosiyanasiyana yama motors, chifukwa chamitundu yosiyanasiyana yogwirira ntchito, padzakhala zisankho zosiyanasiyana pamapangidwe a torque, zodziwika bwino ndi ma mota wamba, ma torque apamwamba ogwirizana ndi katundu wapadera, ndi ma mota ozungulira.

Wamba khola galimoto ndi yachibadwa makokedwe makhalidwe (N kapangidwe), kawirikawiri mosalekeza ntchito, palibe vuto kawirikawiri kuyambira, koma zofunika ndi mkulu dzuwa, otsika kuterera. Pakali pano, YE2, YE3, YE4, ndi ma motors ena apamwamba kwambiri ndi oimira ma motors wamba.

Pamene makina ozungulira ozungulira ayamba, kukana koyambira kumatha kulumikizidwa motsatizana kudzera mu dongosolo la mphete ya wokhometsa, kuti poyambira pakali pano zitha kuyendetsedwa bwino, ndipo torque yoyambira nthawi zonse imakhala pafupi ndi torque yayikulu, yomwe imakhalanso Zifukwa zogwiritsira ntchito bwino.

Pazinthu zina zapadera zogwirira ntchito, injini imafunika kukhala ndi torque yayikulu. M'mutu wapitawu, tidakambirana za ma motors akutsogolo ndi kumbuyo, kukaniza kosalekeza komwe nthawi yolimbana ndi katundu imakhala yosasinthika kuposa ma torque ovotera, zonyamula zokhala ndi mphindi yayikulu ya inertia, katundu wokhotakhota omwe amafunikira mawonekedwe ofewa a torque, ndi zina zambiri.

Pazinthu zamagalimoto, torque ndi gawo limodzi lokha la magwiridwe antchito ake, kuti muwongolere mawonekedwe a torque, pangakhale kofunikira kuperekera magwiridwe antchito ena, makamaka kufananitsa ndi zida zokokera ndikofunikira kwambiri, kusanthula mwadongosolo komanso kukhathamiritsa kwa magwiridwe antchito athunthu. , zothandiza kwambiri kukhathamiritsa ndi kuzindikira magawo a galimoto yamagetsi, kupulumutsa mphamvu kwadongosolo kwakhalanso mutu wa kafukufuku wamba pakati pa opanga magalimoto ambiri ndi zida zothandizira opanga.
