I-Shaft current iwumbulali omkhulu wama-motor frequency motors, ama-motor amakhulu, ama-voltage aphezulu namajeneretha, futhi iyingozi kakhulu ohlelweni lokuthwala izinjini.Kunezimo eziningi zokuhluleka kwesistimu yokuthwala ngenxa yezinyathelo zokuphepha zamanje ze-shaft ezinganele.

I-shaft current ibonakala nge-voltage ephansi kanye nomthamo ophezulu, futhi umonakalo ohlelweni lokuthwala kungathiwa akunakugwenywa.Ukukhiqizwa kwe-shaft current kungenxa ye-shaft voltage kanye ne-loop evaliwe.Ukuxazulula inkinga ye-shaft current, ingaxazululwa ngokususa i-voltage ye-shaft noma ukusika i-loop.

Isekethe kazibuthe engalingani, ukunikezwa kwamandla okushintshashintshayo, ukungeniswa kwe-electrostatic, ukushaja kwe-electrostatic kanye nokuphazamiseka kokuphakelwa kwamandla kwangaphandle konke kungase kukhiqize i-shaft voltage.Ibhekene ne-loop evaliwe, i-shaft current enkulu izobangela ukuthi ukuthwala kuphele ngenxa yokushisa ngesikhathi esifushane kakhulu.Amabhereli ashiswe yi-shaft current azoshiya amamaki afana nebhodi lokuwasha endaweni engaphandle yeringi yangaphakathi ethwele.

Ukuze ugweme inkinga ye-shaft current, izinyathelo ezidingekayo kufanele zithathwe ekuklanyeni nasekukhiqizeni inqubo ye-motor, njengokwengeza izinyathelo zokufaka ezidingekayo kukhava lokugcina kanye nomkhono wokuthwala.Isixhumanisi sinyusa ukuvuza kwebhulashi lekhabhoni.Ngokombono wokusetshenziswa, kuyisinyathelo sakanye kuphela ukuthatha izinyathelo ze-circuit breaker ezingxenyeni, kuyilapho ukusetshenziswa kwezindlela zokuphambukisa kungase kuholele ekushintshweni kwemishini ye-carbon brush, okungenani phakathi nomjikelezo wokunakekela i-motor, uhlelo lwe-carbon brush akufanele lube nezinkinga.

Ubukhulu kanye nomthamo wokuthwala we-insulated bearing kanye nokuthwala okuvamile kuyafana.Umehluko wukuthi i-bearing insulated ingavimbela ukuhamba kwamandla kahle kakhulu, futhi i-insulated bear ingagwema umonakalo obangelwa ukugqwala kagesi.Ukusebenza kunokwethenjelwa kakhulu, futhi i-insulated bear ingagwema umphumela wokugqwala kagesi we-current induced ku-bearing, futhi ivimbele okwamanje ukuthi ibangele umonakalo kugrisi, izakhi eziginqikayo kanye nemigwaqo yomjaho.

Lapho i-motor isetshenziswa ngogesi oguquguqukayo, i-voltage yokuphakelwa kwamandla iqukethe izingxenye ze-harmonic ezi-oda eziphezulu, ezibangela ukungeniswa kwe-electromagnetic phakathi kwamaphethelo amakhoyili ahamba nge-stator, izingxenye zezintambo, kanye ne-shaft ejikelezayo, ngaleyo ndlela ikhiqize i-voltage ye-shaft.

I-stator winding ye-asynchronous motor ishumekwe ku-stator core slot, futhi kukhona amandla asabalalisiwe phakathi kokujika kokujika kwe-stator naphakathi kwe-stator winding kanye nohlaka lwe-motor.I-voltage yemodi evamile ishintsha kakhulu, futhi amandla avuzayo akheka ukusuka ku-motor casing kuya kutheminali yaphansi ngokusebenzisa amandla asabalalisiwe we-motor winding.Lokhu kuvuza kwamanje kungakha izinhlobo ezimbili zokuphazanyiswa kwe-electromagnetic, i-radioactive ne-conductive.Ngenxa yokungalingani kwesekethe kazibuthe yemoto, ukungeniswa kwe-electrostatic kanye ne-voltage yemodi evamile kuyimbangela ye-shaft voltage kanye ne-shaft current.
