Esinye sezizathu zamandla ombane we-shaft kukuba xa kusenziwa i-motor, ngenxa yokungalingani kwe-magnetoresistance ye-stator kunye ne-rotor kwicala le-axial le-iron core circumference, i-magnetic flux iveliswa kwaye i-rotary shaft iyadibana, ngaloo ndlela ibangela amandla e-electromotive. Ngenxa yokuba amandla ombane we-shaft okanye i-shaft voltage akulula ukuyilinganisa, xa kwenzeka ingozi yokutsha kwe-rolling bearing, umonakalo wombane we-shaft uyatyhilwa.
Kukho izizathu ezibini zokuba kubekho i-shaft current: okokuqala, ukungavumi kwe-magnetic circuit ye-magnetic akulingani, kukho i-rotary magnetic flux edibana ne-rotary shaft, kwaye xa i-rotor winding ingaphumeleli emhlabeni, kukho i-ground current; Okwesibini, kukho i-residual magnetic flux kwi-rotary shaft, esebenza njenge-unipolar generator.
Kwimoto enkulu, ingakumbi i-motor eguquguqukayo, amathuba okuba umsinga we-shaft mkhulu, kwaye ingxaki yokubola kombane we-bearing nayo ingaphezulu. Ukuze kusonjululwe le ngxaki ngokusisiseko, kwavela ii-insulated bearings kunye nee-insulated end caps.
Iimeko zokwenziwa komsinga we-axial zezi: enye kukuba kukho i-axial voltage, enye kukwenza i-loop. Kwi-motor enoyilo oluqhelekileyo kunye neemeko zokusebenza, kukho umahluko omncinci kwi-voltage phakathi kweziphelo ezimbini ze-shaft, kwaye ngenxa yonyango lwe-oyile film okanye i-bearing insulation, akwanelanga ukubangela ingozi.
Ukuba kukho ingxaki kwikhonkco elithile, i-voltage ye-shaft idlula ixabiso elimiselweyo, inokuqhekeza i-insulation yokuqala, kwaye yenze i-loop kwi-shaft ejikelezayo, i-ring yangaphakathi ethwele, i-ring yangaphandle ethwele, igumbi lokuthwala, ngoko ke umphezulu wendawo ye-shaft ejikelezayo kunye ne-ring yangaphakathi ethwele iya kuvelisa amanqaku amancinci nanzulu okubola okanye amabala e-arc arc ngenxa yokukhupha i-arc, okwaneleyo ukutshisa i-journal kunye ne-bearing shell.
Ngokwesakhiwo kunye nomgaqo wokusebenza wejenereyitha ehambelanayo, ngenxa yokudibanisa i-stator core joint, i-stator silicon steel sheet joint, umsantsa womoya phakathi kwe-stator kunye ne-rotor awulingani, iziko le-shaft alihambelani neziko le-magnetic field, njalo njalo, i-main shaft yeyunithi iya kujika ngokungenakuphepheka kwi-symmetric magnetic field engaphelelanga. Ngale ndlela, i-AC voltage iveliswa kuzo zombini iziphelo ze-shaft.
