Ugesi we-shaft uyinkinga evamile futhi engenakugwenywa kuma-motor ane-voltage ephezulu kanye nama-motor ane-variable-frequency. Ugesi we-shaft ungabangela umonakalo omkhulu ohlelweni lokuthwala lwemoto. Ngenxa yalesi sizathu, abakhiqizi abaningi bezimoto basebenzisa izinhlelo zokuthwala ezivikela ukushisa noma izindlela zokudlula ukuze bagweme izinkinga zamanje we-shaft. Ukukhiqizwa kogesi we-shaft kungenxa yokudlula kogesi we-magnetic oshintshashintsha isikhathi ngesekethe eyakhiwe ugesi wemoto, ama-bearings, kanye negumbi lokuthwala, okubangela i-voltage ye-shaft ku-shaft futhi kukhiqize ugesi lapho isekethe ivuliwe. Kuyisimo esingokoqobo esine-voltage ephansi, ugesi ophezulu obangela umonakalo omkhulu ohlelweni lokuthwala lwemoto futhi uzobhubhisa ama-bearings ngesikhathi esifushane ngenxa yokuguguleka kwe-electro-erosion. Ukubhoboza kwe-motor core kuyishidi elibunjwe njengefeni elinezikhala ezibekwe nesisekelo. Ugesi ohlukanisiwe wemoto enkulu kanye nokuqina kwe-rotor yizici ezibalulekile ekukhiqizeni ugesi we-shaft. Ngakho-ke, ugesi we-shaft uba yinkinga enkulu yama-motor amakhulu.
Ukuze kugwenywe inkinga yamanje womgodi, kufanele kuthathwe izinyathelo ezidingekayo ekukhetheni nasekuklameni izingxenye nezingxenye ukuze kususwe ngokwethiyori izici ezikhiqiza ugesi womgodi. Inani lemithungo u-S kumjikelezo lilawulwa futhi lilungiswa ubudlelwano phakathi kuka-S kanye ne-divisor evamile kakhulu yenani lama-pair e-motor pole. Uma i-S/t iyinombolo elinganayo, izimo zokukhiqiza ugesi womgodi azihlangatshezwa, futhi ngokwemvelo ngeke kube khona ugesi womgodi; uma i-S/t iyinombolo engajwayelekile, kungenzeka kakhulu ukuthi ugesi womgodi uzokhiqizwa, futhi ugesi womgodi uzokhiqizwa. Ngisho noma lolu hlobo lwemoto luyimoto yemvamisa yezimboni, kuzoba nezinkinga zamanje womgodi. Ngakho-ke, kuma-motor amakhulu, izinyathelo zokugwema ugesi womgodi ngokuvamile ziyathathwa.
Ngaphezu kwalokho, ama-harmonics aphezulu ama-motor e-variable frequency nawo angenye yezizathu zamandla omshini wokushisa. Kungakhathaliseki ukuthi i-motor ye-variable frequency inamandla kangakanani, kungase kube khona amandla omshini wokushisa, ngakho-ke ama-motor amaningi e-small-power variable frequency azosebenzisa ama-insulated bearings, kuyilapho ama-motor amaningi anamandla aphezulu azosebenzisa izembozo zokugcina ezifakwe i-insulated, noma athathe izinyathelo zokushisa endaweni yokubeka i-shaft bearing; ukuze kuqinisekiswe ukuhambisana kwama-motor e-variable frequency kanye nezingxenye ze-motor ze-industrial frequency ezijwayelekile, abanye abakhiqizi bazothatha izinyathelo zokudlula endaweni yesembozo se-bearing.
