ʻO Shaft current kahi mea pepehi nui nui o nā kaʻa kaʻa like ʻole, nā kaʻa nui, nā mīkini uila kiʻekiʻe a me nā mea hana, a he mea pōʻino loa ia i ka ʻōnaehana lawe kaʻa.Nui nā hihia o ka hāʻule ʻana o ka ʻōnaehana bearing ma muli o ka lawa ʻole o ka shaft i kēia manawa.

Hōʻike ʻia ke ʻano o ka shaft e ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe, a hiki ke ʻōlelo ʻia ka pōʻino i ka ʻōnaehana bearing.ʻO ka hoʻokumu ʻana o ka manawa shaft ma muli o ka volta shaft a me ka loop loop.No ka hoʻoponopono ʻana i ka pilikia o ka shaft current, hiki ke hoʻopau ʻia ma ka hoʻopau ʻana i ka volta shaft a i ʻole ka ʻoki ʻana i ka loop.

ʻO ke kaʻapuni magnetic kūpono ʻole, ka mana inverter, induction electrostatic, electrostatic charge a me ka hoʻopili ʻana i ka mana waho hiki ke hoʻohua i ka volta shaft.Ke alo nei me ka puka puka pani, e hoopau ke au o ke kumu nui ma muli o ka wela i ka manawa pokole loa.E waiho ʻia nā kaha e like me ka papa holoi ma ka ʻili o waho o ke apo i loko.

I mea e pale aku ai i ka pilikia o ka manawa o ka shaft, pono e lawe ʻia nā mea e pono ai i ka hoʻolālā ʻana a me ke kaʻina hana o ke kaʻa, e like me ka hoʻohui ʻana i nā ana insulation pono i ka uhi hope a me ka lima lima.Hoʻonui ka loulou i ka leakage carbon brush.Mai ka manaʻo o ka hoʻohana ʻana, he hana hoʻokahi wale nō ia e lawe i nā ana breaker circuit ma nā ʻāpana, ʻoiai ka hoʻohana ʻana i nā ʻano hoʻololi ke alakaʻi i ka hoʻololi ʻana i nā mīkini palaki kalapona, ma ka liʻiliʻi loa i ka wā o ka mālama ʻana o ʻaʻole pilikia ka ʻōnaehana kalapona.

ʻO ka nui a me ka hikiʻana o ka bearing insulated a me ka bearing maʻamau.ʻO ka ʻokoʻa, hiki i ka bearing insulated ke pale i ka hele ʻana o kēia manawa maikaʻi loa, a hiki i ka bearing insulated ke pale i ka pōʻino i hana ʻia e ka uila.ʻOi aku ka hilinaʻi o ka hana, a hiki i ka bearing insulated ke pale i ka hopena o ka hoʻoheheʻe uila o ke au i hoʻokomo ʻia i ka bearing, a pale i ke au mai ka hoʻopōʻino ʻana i ka momona, nā mea ʻōwili a me nā alanui.

Ke hoʻohana ʻia ka kaʻa me ka mana inverter, loaʻa i ka volta lako mana nā ʻāpana harmonic kiʻekiʻe, ka mea e hoʻoulu ai i ka electromagnetic induction ma waena o nā wēlau o ka stator winding coils, nā ʻāpana wiring, a me ka ʻauʻau wili, a laila e hoʻoulu ai i ka volta shaft.

Hoʻokomo ʻia ka wili stator o ke kaʻa asynchronous i loko o ka slot stator core, a aia nā capacitances i māhele ʻia ma waena o nā huli o ka wili stator a ma waena o ka wili stator a me ke kaʻa kaʻa.Hoʻololi koke ka volta mode maʻamau, a ua hoʻokumu ʻia ka leakage mai ka pahu kaʻa a hiki i ka pahu lepo ma o ka capacitance puʻupuʻu o ka wili kaʻa.Hiki i kēia leakage ke hana i ʻelua ʻano o ka hoʻopili electromagnetic, radioactive a me conductive.Ma muli o ke kaulike ʻole o ke kaapuni magnetic o ke kaʻa, ka hoʻokomo electrostatic a me ka volta mode maʻamau ke kumu o ka volta shaft a me ka shaft current.
