Chifukwa chiyani chitetezo chosiyana chimagwiritsidwa ntchito pa ma mota akuluakulu amphamvu kwambiri?

Poyerekeza ndi zazing'ono ndimota zapakatikati,ma mota amphamvu kwambirindi okwera mtengo, ndipo momwe amagwiritsidwira ntchito ndi ofunika kwambiri komanso apadera. Kaya ndi kutaya thupi la injini pambuyo pa vuto kapena mavuto ena obwera chifukwa cha vutolo, likhoza kukhala lalikulu kwambiri kuposa momwe tingaganizire. Pachifukwa ichi, zida zotetezera zosiyana zimagwiritsidwa ntchito pa ma mota amphamvu omwe amagwiritsidwa ntchito nthawi zina zapadera, cholinga chake ndi kupeza mavuto mwachangu komanso moyenera ndikupewa kuwonongeka kwina kwa mavutowo.
Chitetezo chosiyana ndi njira yothandiza kwambiri yotetezera kuti zipangizo zamagetsi zigwire ntchito bwino. Imagwiritsa ntchito makhalidwe oyambitsa zochita zoteteza posiyanitsa pakati pa mphamvu yolowera ndi mphamvu yotuluka yazida zamagetsi, zomwe zimapangitsa kuti netiweki yamagetsi ya madoko awiri, jenereta, mota, transformer ndi zida zina zamagetsi zikhale ndi ntchito zakale kwambiri.

Chitetezo cha differential chimagwiritsidwa ntchito kwambiri pa ma motors akuluakulu amphamvu kwambiri. Mwachitsanzo, ma motors amphamvu kwambiri omwe amagwiritsidwa ntchito mu mgodi waukulu wamagetsi ndi zida zopumira mpweya ayenera kukhala ndi zida zotetezera zosiyana siyana kuti atsimikizire kuti dongosololi likugwira ntchito bwino komanso modalirika komanso kupewa kutayika kwakukulu kwachuma komanso ngozi zachitetezo zomwe zimachitika chifukwa cha kutsekedwa kosayembekezereka.
Ma stator windings a ma mota akuluakulu amphamvu nthawi zambiri amagwiritsa ntchito kulumikizana kwa nyenyezi, ndi ma terminal atatu otulutsa mwachisawawa. Pamene chitetezo chosiyana chikugwiritsidwa ntchito, mota iyenera kukhala ndi ma terminal 6 otulutsa. Chipangizo choteteza chosiyana chomwe chimagwiritsidwa ntchito pa mota chimagwira ntchito motere: kuzindikira ma current oyambira ndi otsiriza a mota, ndikuyerekeza kusiyana kwa gawo ndi amplitude pakati pa ma current oyambira ndi otsiriza. Muzochitika zachizolowezi, kusiyana kwa amplitude ndi gawo pakati pa ma current oyambira ndi otsiriza ndi zero, ndiko kuti, mphamvu yolowera mu mota ndi yofanana ndi mphamvu yotuluka mu mota; pamene vuto la short circuit monga phase-to-phase, turn-to-turn kapena to ground likuchitika mkati mwa mota, mphamvu yosiyana imapangidwa pakati pa ziwirizi ndipo imafika pamtengo winawake, ntchito yoteteza imayatsidwa.
