Shaft current ndi vuto lodziwika bwino komanso losapeĊµekama mota amphamvu kwambirindima motors osintha pafupipafupi. Shaft yapano imatha kuwononga kwambiri makina onyamula agalimoto. Pazifukwa izi, opanga magalimoto ambiri amagwiritsa ntchito njira zotsekera zotchingira kapena njira zodutsamo kuti apewe zovuta zomwe zikuchitika.
Shaft current imapangidwa chifukwa kusinthasintha kwa maginito komwe kumasintha pakapita nthawi kumadutsa mulu wopangidwa ndi shaft yamoto, mayendedwe ndi chipinda chonyamula, kupangitsa voteji ya shaft pa shaft ndikutulutsa pano pomwe chipikacho chimayatsidwa; ndi otsika-voltage, mkulu-pakali pano zochitika zakuthupi zomwe zimayambitsa kuwonongeka kwakukulu kwa kayendedwe ka galimoto ndipo zidzawononga kubereka chifukwa cha electrocorrosion mu nthawi yochepa.
Kukhomerera kwapakati pa injini ndi chidutswa chofanana ndi chowotcha chokhala ndi kagawo kokhala ndi maziko okhomerera; gawo logawanika la mota yayikulu komanso kukhazikika kwa rotor ndizinthu zofunika kwambiri pakupanga shaft pano. Chifukwa chake, shaft current yakhala vuto lalikulu la ma mota akulu.
Pofuna kupewa vuto la shaft pano, njira zoyenera ziyenera kuchitidwa pakusankha ndi kapangidwe ka magawo ndi zigawo zake kuti zithetse mwaukadaulo zomwe zimapanga shaft pano. Chiwerengero cha mfundo S pa circumference imayendetsedwa ndikusinthidwa ndi ubale wapakati pa S ndi gawo lalikulu kwambiri logawa t la kuchuluka kwa ma pole pole awiriawiri.
Pamene S / t ndi nambala yofanana, palibe chikhalidwe chopangira shaft voltage, ndipo mwachibadwa sipadzakhala shaft panopa; pamene S/t ndi nambala yosamvetseka, ndizotheka kuti magetsi a shaft apangidwe, ndipo shaft panopa idzapangidwa. Ngakhale galimoto yamtundu uwu ndi injini yamagetsi yamagetsi, padzakhala zovuta zapa shaft. Chifukwa chake, pama motors akulu, njira zopewera shaft current nthawi zambiri zimatengedwa.
Kuphatikiza apo, ma frequency frequency motors ndi chimodzi mwazifukwa zopangira shaft current chifukwa cha ma harmonics apamwamba kwambiri amagetsi osinthika. Ziribe kanthu kuti ma frequency frequency motor ndi amphamvu bwanji, pakhoza kukhala shaft current. Chifukwa chake, ambirima motors ang'onoang'ono osinthika pafupipafupiadzagwiritsa ntchito zotchingira zotchinga, pomwe ma mota ambiri amphamvu kwambiri adzagwiritsa ntchito zotchingira zotsekera, kapena kutenga njira zotchinjiriza pamalo opangira shaft; opanga ena, kuti awonetsetse kuti ma injini a frequency frequency afanana ndi magawo wamba amagetsi amagetsi amakampani, atenga njira zolambalala pamalo oyambira.
