N’chifukwa chiyani injini zina zimagwiritsa ntchito chishango choteteza kumapeto?

Chimodzi mwa zifukwa zomwe zimapangitsa kuti shaft current igwire ntchito ndi chakuti popanga mota, chifukwa cha kusalingana kwa maginito a stator ndi rotor motsatira njira ya axial ya circumference ya iron core, maginito flux amapangidwa ndipo shaft yozungulira imalumikizana, zomwe zimapangitsa mphamvu ya electromotive. Chifukwa chakuti shaft current kapena shaft voltage si yosavuta kuyeza, ngozi yoyaka ya rolling bearing ikachitika, kuwonongeka kwa shaft current kumawululidwa.

Pali zifukwa ziwiri zomwe zimapangitsa kuti magetsi a shaft current ayambe kugwira ntchito: choyamba, kukana kwa maginito kwa dera la maginito kumakhala kosagwirizana, pali flux yozungulira ya maginito yomwe imalumikizana ndi shaft yozungulira, ndipo pamene rotor winding yalephera kufika pansi, pamakhala flux yotsalira ya maginito pa shaft yozungulira, yomwe imagwira ntchito ngati jenereta ya unipolar.

Pa mota yayikulu, makamaka mota yosinthasintha, mwayi wa shaft current ndi waukulu, ndipo vuto la dzimbiri lamagetsi onyamula ndi lalikulu. Pofuna kuthetsa vutoli, ma bearing otetezedwa ndi ma end caps otetezedwa anapangidwa.

Zinthu zomwe zimapangitsa kuti magetsi a axial current apangidwe ndi izi: chimodzi ndi chakuti pali magetsi a axial, ndipo china ndi kupanga lupu. Mu mota yokhala ndi kapangidwe kabwinobwino komanso momwe imagwirira ntchito, pali kusiyana kochepa kwa magetsi pakati pa malekezero awiri a shaft, ndipo chifukwa cha kukonzedwa kwa filimu yamafuta kapena chotenthetsera, sikokwanira kuvulaza.

Ngati pali vuto mu ulalo winawake, mphamvu ya shaft imapitirira malire, ikhoza kuswa insulation yoyambirira, ndikupanga kuzungulira mu shaft yozungulira, mphete yamkati yokhala ndi mphete, mphete yakunja yokhala ndi mphete, chipinda choperekera, kotero pamwamba pa malo operekera shaft yozungulira ndi mphete yamkati yokhala ndi mphete idzapanga mfundo zazing'ono komanso zozama zozungulira kapena zipsera za arc chifukwa cha kutuluka kwa arc, zomwe ndizokwanira kutentha journal ndi chipolopolo choperekera.

Malinga ndi kapangidwe ndi mfundo yogwirira ntchito ya jenereta yolumikizana, chifukwa cha kuphatikiza kwa cholumikizira cha stator core, cholumikizira cha stator silicon steel sheet, kusiyana kwa mpweya pakati pa stator ndi rotor ndi kofanana, pakati pa shaft sikugwirizana ndi pakati pa magnetic field, ndi zina zotero, shaft yayikulu ya chipangizocho idzazungulira mosalephera mu symmetric magnetic field yosakwanira. Mwanjira imeneyi, AC voltage imapangidwa kumapeto onse a shaft.
