Esinye sezizathu zamandla omshini ukuthi ekukhiqizweni kwenjini, ngenxa yokungalingani kwe-magnetoresistance ye-stator ne-rotor eceleni kwesiqondiso se-axial se-iron core circumference, kukhiqizwa i-magnetic flux bese kuthi i-rotary shaft ihlangane, ngaleyo ndlela kubangele amandla e-electromotive. Ngenxa yokuthi amandla omshini noma i-shaft voltage akulula ukuyilinganisa, lapho kwenzeka ingozi yokusha kwe-rolling bearing, umonakalo wamandla omshini uyavezwa.
Kunezizathu ezimbili zamandla kagesi we-shaft: okokuqala, ukungafuni kwamandla kagesi wesekethe yamagnetic akulinganiselanga, kukhona i-flux yamagnetic ejikelezayo ehlangana ne-shaft ejikelezayo, futhi lapho ukugoqa kwe-rotor kwehluleka phansi, kuba khona amandla kagesi omhlaba; Okwesibili, kukhona i-flux yamagnetic esele e-shaft ejikelezayo, esebenza njengejeneretha ye-unipolar.
Kuma-motor amakhulu, ikakhulukazi ama-motor aphindaphindayo, amathuba okuba khona komshini wokushisa omkhulu makhulu, kanti inkinga yokugqwala kukagesi okuthwala nayo inkulu kakhulu. Ukuze kuxazululwe le nkinga ngokuyisisekelo, kwavela ama-bearings afakwe umswakama kanye nama-end cap afakwe umswakama.
Izimo zokwakheka komshini we-axial yilezi: enye ukuthi kukhona i-axial voltage, kanti enye ukwakha i-loop. Emotweni enomklamo ojwayelekile nezimo zokusebenza, kunomehluko omncane kakhulu ku-voltage phakathi kwezinhlangothi ezimbili zomgodi, futhi ngenxa yokwelashwa kwefilimu kawoyela noma i-bearing insulation, akwanele ukubangela umonakalo.
Uma kunenkinga ekuxhumaneni okuthile, i-voltage ye-shaft idlula inani elilinganiselwe, ingase iphule ukufakelwa kokuqala, futhi yakhe i-loop ku-shaft ejikelezayo, indandatho yangaphakathi ephethe, indandatho yangaphandle ephethe, igumbi lokuthwala, ngakho-ke ubuso bendawo yokuthwala i-shaft ejikelezayo kanye nendandatho yangaphakathi ephethe kuzokhiqiza amaphuzu okugqwala amancane najulile noma izibazi ze-arc ezisikiwe ngenxa yokukhishwa kwe-arc, okwanele ukushisa i-journal kanye negobolondo lokuthwala.
Ngokwesakhiwo kanye nesimiso sokusebenza sejeneretha ehambisanayo, ngenxa yokuhlanganiswa kwejoyinti ye-stator core, ijoyinti yeshidi lensimbi ye-stator silicon, igebe lomoya phakathi kwe-stator ne-rotor alilingani, isikhungo se-shaft asihambisani nesikhungo sensimu yamagnetic, njalo njalo, i-shaft eyinhloko yeyunithi izojikeleza ngokungenakugwenywa ensimini yamagnetic engaphelele. Ngale ndlela, kukhiqizwa i-AC voltage kuzo zombili iziphetho ze-shaft.
