Zida zamagetsi zamagetsi zimagwiritsidwa ntchito kwambiri zida zamagetsi. Malinga ndi mawonekedwe osiyanasiyana ogwiritsira ntchito injiniyo, amagawidwa m'magulu osiyanasiyana, monga ma mota omwe amagwiritsidwa ntchito makamaka pakukweza zitsulo, nsalu, roller ndi zina zomwe zimafunikira. Kutengera ndi zomwe munthu amafunikira pamagwiritsidwe ntchito, kapangidwe kake ndi kachitidwe ka mota kamakhala kokwaniritsa zofunikira.
M'magawo amagetsi agalimoto, pali mapangano ochulukirapo pamphamvu yagalimoto ndi liwiro, ndipo torque imawonetsedwa ngati chofunikira; kwa ma frequency motors osinthika, akakhala otsika kuposa ma frequency oyambira, amatuluka mumayendedwe okhazikika, ndipo mota ikakhala yapamwamba kuposa ma frequency angapo, imayenda motsatira mphamvu.
Torque, monga chimodzi mwazochita zazikulu zamagalimoto, ndiye chizindikiro chachikulu chagalimoto. Kwa ma motors omwe ali ndi mphamvu zomwezo, torque yama motors othamanga kwambiri ndi yaying'ono, ndipo torque ya ma mota otsika kwambiri ndi yayikulu; pakugwiritsa ntchito makina opanga, nsalu, kupanga mapepala, mphira, mapulasitiki, mawaya achitsulo ndi mawaya ndi zingwe ndi mafakitale ena, injini yomwe imatha kupereka torque nthawi zonse imafunika, yomwe imatchedwa torque motor.
Torque motor ndi injini yapadera yokhala ndi mawonekedwe ofewa wamakina komanso liwiro lalikulu. Makhalidwe ake ndikuti injini imakhala ndi mizati yambiri, ndiko kuti, liwiro ndilotsika, ndipo galimotoyo imatha kupitiriza kuthamanga pa liwiro lotsika kapena ngakhale kuyimitsidwa, pamene ma motors wamba adzakhala pachiopsezo chowotcha mphepo chifukwa cha kuwonjezeka kwadzidzidzi kwa panopa. pa liwiro lotsika komanso loyima.
Ma torque motors amagwiritsidwa ntchito m'malo ogwirira ntchito omwe amafunikira torque yokhazikika. Shaft ya torque motor imatulutsa mphamvu pa torque yosasintha m'malo mokhala ndi mphamvu nthawi zonse. The torque motor imatha kupereka ma torque abwino ndi ma torque omwe amatsutsana ndi komwe akugwirira ntchito.
Ma mota a torque okhala ndi ma torque osasinthasintha amatha kugwira ntchito pa liwiro lalikulu ndikusunga ma torque nthawi zonse. Ndioyenera nthawi zotumizira pomwe liwiro limasintha koma torque yokhazikika ndiyofunikira. Komabe, ngati injiniyo ikugwira ntchito pa liwiro lotsika kapena ngakhale kuyimitsidwa kwa nthawi yayitali, injiniyo imatha kutentha kwambiri. Ntchito yotsekereza yamagetsi yamagalimoto ndi makina onyamula mafuta amayenera kukhala ndi zida zapadera, ndipo njira yolumikizira mpweya yokakamiza kapena njira zoziziritsira zamadzimadzi ziyenera kukhazikitsidwa kuti mota ichotse kutentha.
