Ukugcoba kuyisimo esidingekayo sokusebenza okujwayelekile kwama-motor bearings. Ama-rolling bearings agcotshwe ngamafutha futhi angama-bearings asetshenziswa kakhulu emikhiqizweni yezimoto. Ama-rolling bearings ahlukaniswa abe ama-bearings avulekile futhi avaliwe. Ama-bearings avaliwe agcwaliswa ngamafutha lapho ephuma efektri futhi akudingeki aphinde agcwaliswe lapho kuhlanganiswa injini. Ukugcinwa kwama-bearings kungashintshwa ngokuvumelana nempilo yesevisi ye-motor noma i-bearing. Kuma-motor amaningi, kusetshenziswa ama-bearings avulekile, okungukuthi, umenzi wezimoto ugcwalisa ama-bearings ngamafutha afanelekile ngokuya ngezimo zokusebenza ezahlukene.
Enqubweni yokusebenza yemoto, kutholakala ukuthi amanye ama-motor anokusebenza okuzinzile lapho esanda kuqaliswa, kepha ngemuva kokusebenza isikhathi esithile, umsindo ozwakalayo ozwakalayo ngenxa yokugcotshwa okubi kwenzeka. Le nkinga yenzeka ngezikhathi ezithile phakathi nesigaba sokuhlola semoto kanye nesiteji sokusebenza kwemoto.
Isizathu esibalulekile sokungagcolisi kahle kwe-motor bear ukuthi igrisi yasekuqaleni ayikwazi ukuhanjiswa ngemuva kokulahlwa ngaphandle. Ukuze uxazulule le nkinga, kuyadingeka ukuqala ngomklamo wesistimu yokuthwala imoto, futhi ngokusebenzisa izithiyo ezidingekayo zesikhala somzimba, unciphise ububanzi bokuhamba kwamafutha, futhi uphoqe amafutha aphonsiwe ukuthi angene emgodini wokuzala futhi.
Ngokuhlaziywa okuqhathaniswayo kwezinhlaka ezithwala izimoto zabakhiqizi bezimoto abahlukene, kungatholakala ukuthi abanye abakhiqizi bezimoto bathuthukisa uhlelo lokuthambisa oluthwalayo ngokulungisa usayizi womgodi wekhava elithwalayo, kuyilapho abanye abakhiqizi bezimoto benqanda isikhala sokugeleza samafutha ngokungeza umqondo wokuthwala ipani lokujiya uwoyela.
Ngaphandle kwezithiyo kanye nemikhawulo yendawo yokugcoba yesistimu yokuthwala, ubuhlobo obuhambisanayo phakathi kwesihlalo sokuthwala kanye nesihlalo esithwalayo, kanye negumbi lokuthwala kanye negumbi lokuthwala kubaluleke kakhulu ukuvimbela ukuwohloka nokwehluleka kwamafutha ngemuva kokushisa kokushisa ngenxa yokuhambisana okungalungile; ukulawulwa kwe-axial position ye-motor rotor, okungukuthi, lokho esikubiza ngokuthi ukulawula ukunyakaza kwe-axial, kufanele futhi kusetshenziselwe ukunciphisa inkinga yamafutha aphoqeleka ukuba akhishwe emgodini we-shaft.
