Xa kuthelekiswa neiimoto ezine-voltage ephantsi, iimoto ezine-voltage ephezulu, ingakumbi iimoto ezine-voltage ephezulu ezingasebenziyo, ikakhulu zisekelwe kwisakhiwo se-cage rotor. Ngexesha lokwenziwa nokusebenza kweemoto, ngenxa yokulungelelaniswa okungafanelekanga kweendawo zesakhiwo se-mechanical, kunokukhokelela ekungcangcazeleni okukhulu kwemoto, okunokuba kukungcangcazela kwe-radial okanye ukungcangcazela kwe-axial.
Umsantsa womoya ongalinganiyo phakathi kwe-stator kunye ne-rotor yeyona nto iphambili yokungcangcazela kwe-motor. Kwinkqubo yokuvelisa nokucutshungulwa, xa ifreyimu ye-motor, i-stator core kunye nenxalenye ye-rotor zingabi yi-coaxial, ziya kukhokelela ngokuthe ngqo kumsantsa womoya ongalinganiyo we-motor, kwaye emva kokuba i-motor inikwe amandla, iya kubangela ukungcangcazela kwe-electromagnetic ye-motor ngenxa yoxinzelelo lwe-magnetic oluvela kwicala elinye, olubangela ukungcangcazela, ukongeza ekungcangcazeleni koomatshini, kodwa lukwahamba nesandi se-electromagnetic esiphantsi. Kwi-motor esebenzayo, ingakumbi i-motor emva kokulungiswa, ngenxa yokusebenza kwexesha elide, i-motor bearing, i-bearing chamber, i-bearing diameter inokubakho ukuphambuka okuthile, okubangela ukulungelelaniswa okungafanelekanga phakathi komnye nomnye, okubangela iingxaki zokungcangcazela kwe-motor. Kwiindawo ezihambelanayo ze-bearing irring yangaphakathi neyangaphandle, xa kukho ingxaki enkulu yokukhululeka, ukungaphumeleli komgangatho obulalayo we-bearing kuya kwenzeka ngexesha elifutshane ngenxa ye-bearing running ring kwaye i-bearing iya kutshisa ide itshiswe.
Kwinxalenye yerotor yemoto, ngenxa yokuguquka kwebha yesikhokelo serotor kunye nokungaphumeleli kwesimo sokuqala sokulinganisela ngexesha lokusebenza kwemoto, umzimba werotor awulingani, nto leyo ebangela impazamo eqhelekileyo ekusebenzeni kweemoto ezinevolthi ephezulu nephantsi. Kwiimoto ezinevolthi ephezulu, ingakumbi ezo zinevolthi ephezuluiibheringi ezityibilikayo, ukungalungelelani kakuhle komgca weziko lemagnethi yimbangela eyintloko yokungcangcazela kwe-axial yemoto, nto leyo eyintloko yolawulo oluhle ngexesha lokufakwa nokusetyenziswa kweemoto ezine-voltage ephezulu. Ukuze kuthintelwe iingxaki ezifanayo, ulawulo lwenkqubo yokuqalisa lubaluleke kakhulu kwiimoto ezine-voltage ephezulu zekheji ukuthintela ubunzima bokuqala kweemoto obubangelwa kukungabikho kwamandla ombane aneleyo.
Kuhlalutyo nokuhlolwa kweengxaki zokungcangcazela kwemoto, kufuneka kuhlolwe izinto ezifunekayo ukuze kufunyanwe unobangela wengcangcazelo. Ezinye iiyunithi zokulungisa iimoto, ezithambekele ekuthatheni indawo ye-bearing, xa sithetha ngokuchanekileyo, i-bearing ayihlangabezani nengxaki yokungcangcazela kwemoto, kodwa i-bearing ayisombululi ingxaki yokungcangcazela kwemoto, ngoko ke uhlalutyo olunzulu olupheleleyo lunceda ngakumbi kwisisombululo sengxaki. Ngenxa yezizathu ze-electromagnetic, ukungalingani kwe-winding kunye nokungaphumeleli komgangatho wombane we-winding kuya kukhokelela kwi-magnetic field engalinganiyo yemoto, eya kukhokelela nakwi-electromagnetic vibration yemoto, ebonakala ngakumbi njenge-violent jitter ehamba nesandi esibi kakhulu, kwaye ukungcangcazela koomatshini kusahlukile, kwaye kunokwahlulwa ngokucacileyo kwinkqubo yohlalutyo.
