Uma kuqhathaniswa namamotho amancane, uhlelo lokuthwala lwamamotho amakhulu luyinkimbinkimbi kakhulu. Akuwenzi umqondo omkhulu ukuxoxa ngama-motor bearings uwedwa; esikhundleni salokho, ingxoxo kufanele ihlanganise izingxenye ezihlobene ezifana namashafu, izindlu ezithwalayo, izembozo zokugcina, kanye nesembozo esinesibopho sangaphakathi nangaphandle. Ukuhambisana nalezi zingxenye ezihlotshaniswayo kumane kuwukulingana komshini, kodwa uNksz Can ukholelwa ukuthi kufanele futhi kucabangele izici zangaphandle njengezimo zokusebenza kwemoto.
Ekusebenzeni kwangempela nasekusetshenzisweni kwama-motor, inkinga evame kakhulu umsindo ovela kuma-bearings. Le nkinga ingase ihlobane nekhwalithi yama-bearings ngokwawo ngakwesinye isandla, futhi ngakolunye uhlangothi, ingase ihlotshaniswe nokukhethwa kwama-bearings. Iningi lezinkinga lisukela ezenzweni ezingafanele noma ezingenangqondo enqubweni yokukhiqiza eziholela ekuthwaleni izinkinga.
Siyazi ukuthi umsindo usuka ekudlidlizeni. Ukubhekana nenkinga yomsindo wama-bearings, inkinga eyinhloko okufanele ixazululwe ukudlidliza. Uma kuqhathaniswa namamotho amancane namamotho ajwayelekile, amamotho amakhulu, ama-high-voltage motors, namamotho okulawula isivinini esiguquguqukayo nawo abhekana nenkinga ye-shaft current. Ukuxazulula le nkinga, umuntu angasebenzisa ama-bearings afakwe i-insulated, kodwa izindleko zokuthengwa kwalezi zinsimbi ziphakeme kakhulu, futhi amanye ama-insulated bearings awakabi khona kabanzi. Enye indlela ukusebenzisa amabhulashi e-grounding carbon, kodwa le ndlela inzima kakhulu ukuyigcina. Ngenxa yalesi simo, abakhiqizi abaningi bezimoto bafuna izixazululo ezindlini ezithwalayo futhi basungule izindlu ezifakwa ngaphakathi. Kodwa-ke, lezi zindlu ezithwala i-insulated ziyinkimbinkimbi kakhulu ukuzenza. Isimiso esiyisisekelo siwukuhlukanisa izindlu ezithwalayo zibe izingxenye ezimbili bese uvala ingxenye yekamelo elithwalayo, ngaleyo ndlela unqamule ngokuphelele umjikelezo obangelwa i-shaft voltage kanye ne-shaft current, okuyisixazululo sesikhathi esisodwa. Lesi sibalo esilandelayo siwumbono oyingxenye yezindlu ezifakwa ngaphakathi.
Lolu hlobo lwezindlu ezithwala i-insulated zingahlukaniswa zibe umkhono wangaphakathi kanye nomkhono wangaphandle, ne-insulating filler phakathi kwemikhono yangaphakathi nangaphandle. Ubukhulu besendlalelo se-insulating filler buyi-2-4mm. Lezi zindlu ezithwala i-insulated, ngokusebenzisa ungqimba lwe-insulating filler, luhlukanisa umkhono wangaphakathi nomkhono wangaphandle, osebenza ukuvimba i-shaft current, ngaleyo ndlela ivikele ama-bearings futhi inwebe impilo yabo yesevisi.
Abanyemotor corelessabakhiqizi baphinde basebenzise amabhodi okuvikela ukuvikela lo mphumela, kodwa ukusebenza kwe-insulating yamabhodi okuvikela kuzokwehla lapho eba manzi. Ukwengeza, kungase kube nezikhala zomoya phakathi kwezindawo ezimbili zamakholomu ngenxa yobukhulu obungalingani bebhodi le-insulating noma izindawo zekholomu ezingahlangabezani nokuyindilinga okudingekayo, okungase kube nomthelela othile ekusebenzeni kwezindlu ezithwalayo. Kunconywa ukuthatha izinyathelo ezidingekayo zokulungisa.
