Izinto ezisetshenziswa kakhulu zama-motor core amashidi ensimbi e-silicon. Njengamanje, asetshenziswa kakhulu angamashidi angu-470, 600 kanye no-800 asemashidini aqoqwe ngokubandayo, phakathi kwawo amashidi angu-470 kanye no-600 asetshenziswa kaningi kuma-motor asebenza kahle kakhulu.
1. Ukulahlekelwa okuphansi.
Ukulahleka kwe-core ngemvamisa ethile kanye nokuqina kokungeniswa kwe-magnetic kuyisibonakaliso esikhulu samashidi ensimbi kagesi. Ukulahleka kwe-core kuqukethe izingxenye ezimbili: ukulahleka kwe-hysteresis kanye nokulahleka kwamanje we-eddy. Ukulahleka kwe-hysteresis ukusetshenziswa kwamandla okubangelwa ukushintshwa kwe-magnetization ye-core, okuhlobene nokwakheka kwezinto kanye nosayizi wezinhlamvu, futhi kungamelwa yindawo ye-hysteresis loop. Ukulahleka kwamanje we-eddy ukulahleka kokumelana okubangelwa ukushintshwa kwe-eddy current okukhiqizwa ngesikhathi sokushintshwa kwe-magnetization ye-core, okuhlobene nokumelana nobukhulu bezinto. Ngakho-ke, ukuze kuncishiswe ukulahleka kwe-core, amashidi ensimbi kagesi anobukhulu obuncane kanye nokumelana okuphezulu.
2. Ukuqhuba okuphezulu kwamandla kazibuthe.
Uma ugesi uphakeme kakhulu, indawo encane yesekethe yamagnetic ingancishiswa uma uketshezi luhlala lungaguquki, okusindisa ithusi elisetshenziswa ekugqugquzeleni umoya futhi kunciphisa usayizi wenjini.
3. Izakhiwo ezinhle zokulamina.
Amapuleti ensimbi kagesi kufanele abe nobunzima obufanele, angaqhekeki kakhulu noma athambile kakhulu. Ubuso kufanele bube bushelelezi, bube yisicaba, futhi bufane ngobukhulu (ngesidingo sokulawula umehluko wamapuleti), okuhambisana nokubhoboza isikhunta nokuthuthukisa i-coefficient yokubeka. Isikhunta esifanayo singasetshenziswa kumapuleti ensimbi abhoboza abandayo, futhi impilo yaso yesevisi ingandiswa kakhulu uma kuqhathaniswa namapuleti ensimbi abhoboza ashisayo. Amanye amapuleti ensimbi kagesi abhoboza abandayo anezimbozo ezingaphili noma eziphilayo angandisa inani lokubhoboza ngokudlula ngakunye kwesikhunta cishe izikhathi eziyishumi ngemva kokugaya kanye. ●Izindleko eziphansi futhi kulula ukuzisebenzisa. Ngaphezu kwezidingo ezingenhla, amanye ama-motor avame ukuba nezidingo eziphakeme zezinto eziqhuba ugesi. Isibonelo, ukwehluleka okuncane kukagesi kanye nokwanda okuncane kukagesi. Lezi zidingo ziyahlukahluka futhi kufanele zicatshangelwe ngokuphelele.
●Ishidi lensimbi le-silicon
Insimbi ehlanganisiwe equkethe i-silicon, egoqwa ibe amashidi amancane. Ngokuvamile ibizwa ngokuthi ishidi lensimbi le-silicon. Kuye ngenqubo yokukhiqiza, ihlukaniswa ibe yishidi lensimbi le-silicon eligoqwe ngokushisa (eliye lasuswa kakhulu) kanye neshidi lensimbi le-silicon eligoqwe ngokushisa. Ishidi lensimbi le-silicon eligoqwe ngokushisa lingahlukaniswa kabanzi ngezinhlobo eziqondiswe kanye nezingezona eziqondiswe. Njengamanje, amashidi ensimbi ye-silicon anikezwa kakhulu ngesimo seshidi. Ukuze kuthuthukiswe izakhiwo zikagesi zeshidi lensimbi le-silicon futhi kuncishiswe amandla alo okucheba, amashidi ensimbi ye-silicon yasekhaya aphathwe nge-annealing emshinini wokugoqa.
●Insimbi engenashidi le-silicon
I-motor core isebenzisa amashidi ensimbi ye-silicon esikhundleni samapuleti ensimbi anekhabhoni ephansi kanye nensimbi emsulwa. Lokhu kwaba yintuthuko ebalulekile emlandweni. Amashidi ensimbi ye-silicon aphansi athuthukisa ukusebenza kwemoto futhi anciphisa usayizi wayo. Manje, esikhundleni sokusebenzisa amashidi ensimbi ye-silicon, amashidi ensimbi ane-silicon ephansi (aziwa nangokuthi ama-strip ensimbi kagesi anekhabhoni ephansi noma ama-strip ensimbi kagesi ehlanzekile) asetshenziselwa ukwenza ama-core ezimoto ezincane ngoba amashidi ensimbi ane-silicon ephansi akhiqizwa ubuchwepheshe besimanje ahlukile kumapuleti ensimbi ephansi enekhabhoni yokuqala. Awagcini nje ngokuba namandla aphezulu okufakwa kwamandla kagesi kodwa futhi anokulahlekelwa yinsimbi okufana nokwamashidi ensimbi ye-silicon. Ama-motor amancane e-AC aklanywe futhi akhiqizwa ngamashidi ensimbi ane-silicon ephansi anganciphisa usayizi, anciphise isisindo, futhi anciphise izindleko. Ngaphezu kwalokho, ngoba amashidi ensimbi ane-silicon ephansi athambile, angandisa isivinini sokubhoboza futhi andise isikhathi sokuphila kwesikhunta. Manje, amashidi ensimbi ane-silicon ephansi asetshenziswa kabanzi njengezinto eziyinhloko zama-motor amancane emazweni angaphandle. Emazweni athuthukile, ukusetshenziswa kwawo kubalwa cishe ama-50-60% womkhiqizo ophelele wamashidi ensimbi kagesi.
Njengamanje, kunezimo ezimbili lapho ifektri yezimoto isebenzisa khona amashidi ensimbi angewona awe-silicon. Esinye ukuthi amashidi ensimbi angewona awe-silicon ngemva kokugoqwa okubandayo abhotshozwa ngqo kumashidi, bese kwenziwa ukwelashwa kokunamathisela emshinini wezimoto; esinye ukuthi amashidi ensimbi abhotshoziwe anikezwa yi-steel mill abhotshozwa futhi asetshenziswe ngqo yi-motor firm. Amashidi ensimbi angewona awe-silicon ayizinto ezisebenzisa amandla kagesi aphezulu, futhi ukuqina kwawo kanye nokulahlekelwa kwawo amandla kagesi kuthinta kakhulu ukucindezeleka komshini. Ngakho-ke, ngemva kokubhotshozwa nangaphambi kokusebenzisa, ukususa ukunamathisela ukucindezeleka kuyisinyathelo esibalulekile sokuthuthukisa ukusebenza kwamandla kagesi. Ukwelashwa ngokushisa kwamashidi ensimbi angewona awe-silicon kudinga imishini ekhethekile yokwelapha ukushisa, kodwa izimboni eziningi zezimoto ezweni lethu azinazo izimo ezinjalo okwamanje. Lena inkinga edinga ukuxazululwa lapho kusetshenziswa amashidi ensimbi angewona awe-silicon.
● Okuqukethwe kwe-silicon kanye ne-silicon yokungcola kunethonya elibalulekile ekusebenzeni kwamashidi ensimbi ye-silicon. Ngemva kokufaka i-silicon ensimbini, ukumelana kuyanda, futhi kusiza nokuhlukanisa ikhabhoni yokungcola eyingozi. Ngokuvamile, lapho insimbi emsulwa ingezwa ne-silicon, amandla okufakwa kwamagnetic ayancipha kancane, kodwa ukulahleka kwensimbi kuyancipha kakhulu. Njengoba okuqukethwe kwe-silicon kuyanda, ubulukhuni kanye nokuqhekeka kuyanda, okuletha ubunzima ekugingqini, ekunyathelweni, ekugundeni, nasekucutshungulweni kwemishini. Njengamanje, okuqukethwe kwe-silicon kwamashidi ensimbi ye-silicon ngokuvamile akudluli ku-4.5%. Uma okuqukethwe kwe-silicon kuphakeme, kunzima ukwenza ukugingqika nokucubungula.
●Ukujiya.Uma sibheka ukuthi ukulahleka kwamandla kagesi enkabeni yensimbi kuhambisana nesikwele sobukhulu beshidi lensimbi, ngohlobo olufanayo lweshidi lensimbi le-silicon, ukujiya kuyancipha, ukulahleka kwenkabeni yensimbi kuncane, kodwa isikhathi sokukhiqiza kwenkabeni yensimbi siyanda futhi i-coefficient yokubeka izimpahla iyancipha. Ngokuvamile, ama-motor asebenzisa amashidi ensimbi e-silicon anobukhulu obungamamilimitha angu-0.5, futhi lapho izidingo zokulahlekelwa kwenkabeni yensimbi zamajeneretha amakhulu e-turbine ye-steam ziqinile kakhulu, kusetshenziswa amashidi ensimbi e-silicon anobukhulu obungamamilimitha angu-0.35.
●Ukucindezeleka.Ngesikhathi sezinqubo zokugunda, ukuhlanganisa, noma ukugoqa ingaphakathi lensimbi, kuzokhiqizwa ukucindezeleka, okunciphisa ukusebenza kwamandla kazibuthe futhi kwandise ukulahleka kwensimbi. Ebangeni elingaba yi-milimitha elilodwa ezinhlangothini zombili zomugqa wesigaba sokusika (sokuphuka), kwakheka indawo yokucindezeleka eseleyo yomcu omnyama ebonakalayo. Ngokuvamile, ukwelashwa kokufaka i-annealing kungasetshenziswa ukuze kuqedwe ukucindezeleka futhi kubuyiselwe ukusebenza kwamandla kazibuthe kokuqala; ukusebenza kwamandla kazibuthe kwamashidi ensimbi e-silicon aqinisiwe asebenza kahle kakhulu kuzwela kakhulu ekucindezelekeni.
