Njira zoziziritsira ma mota amphamvu kwambiri ndiye chinthu chofunikira kwambiri pakuwonetsetsa kuti makina amphamvuwa akugwira ntchito moyenera komanso kukhala ndi moyo wautali. Ma motors okwera kwambiri nthawi zambiri amagwiritsidwa ntchito m'mafakitale ndipo amakhala ndi ntchito zolemetsa komanso zovuta. Chifukwa chake, njira zoziziritsira zogwira mtima ndizofunikira kwambiri kuti mupewe kutentha kwambiri komanso kuti muzichita bwino.
Kuzizira kwamphamvu kwambiri ndi njira yotchuka chifukwa cha kuthekera kwake kutulutsa bwino kutentha kuchokera kumagetsi okwera kwambiri. Ukadaulo umaphatikizapo kugwiritsa ntchito zoziziritsa kukhosi zothamanga kwambiri kuchotsa kutentha kuzinthu zamagalimoto monga stator ndi rotor. Choziziriracho chimazungulira mwachangu kwambiri kuti chikwaniritse kutentha kwachangu komanso kuzizirira koyenera. Njirayi ndi yothandiza makamaka pazovuta zomwe njira zoziziritsira zachikhalidwe sizingakhale zokwanira.
Mosiyana ndi izi, pali njira zingapo zoziziritsira zomwe zimagwiritsidwa ntchito kwambiri pama injini othamanga kwambiri, iliyonse ili ndi zabwino zake komanso zolephera zake. Mwachitsanzo, kuziziritsa kwa mpweya kumadalira kuzungulira kwa mpweya kuzungulira galimoto kuti iwononge kutentha. Ngakhale kuti njirayi ndi yophweka komanso yotsika mtengo, singakhale yoyenera kugwiritsa ntchito mphamvu zamphamvu kapena malo omwe ali ndi kutentha kwakukulu. Kuziziritsa kwamadzi, Komano, kumaphatikizapo kugwiritsa ntchito choziziritsira, monga madzi kapena mafuta, kuchotsa kutentha kwa injini. Njirayi ndi yothandiza kwambiri kuposa kuziziritsa mpweya koma imafunikira zida zowonjezera ndi kukonza.
Chimodzi mwa kusiyana kwakukulu pakati pa kuzizira kwapamwamba kwambiri ndi njira zina ndi liwiro ndi mphamvu zomwe kutentha kumachotsedwa. Kuziziritsa kwamphamvu kwambiri kumachotsa kutentha kwa injini, ndikupangitsa kuti ikhale yabwino pamapulogalamu ofunikira. Kuonjezera apo, kuzizira kwakukulu kumapereka kuzizira kwambiri kwa zigawo za galimoto, kuchepetsa chiopsezo cha malo otentha ndi kupsinjika kwa kutentha.
Kuziziritsa kwamphamvu kwambiri kumapereka njira yothetsera kuziziritsa kwa ma mota okwera kwambiri, makamaka pamafakitale ofunikira. Ngakhale pali njira zingapo zoziziritsira zomwe mungasankhe, kuthekera kwapadera kwa kuziziritsa kwamphamvu kwambiri kumapangitsa kuti ikhale njira yofunikira pakuwonetsetsa kuti ma mota othamanga kwambiri akugwira ntchito moyenera. Kumvetsetsa kusiyana kwa njira zoziziritsira ndizofunika kwambiri posankha njira yoziziritsira yoyenera kwambiri potengera zofunikira za injini ndi malo omwe imagwirira ntchito.
