Izinto ezichaphazela ukusetyenziswa kwesinyithi esisisiseko
Ukuze sihlalutye ingxaki, kufuneka siqale sazi ezinye iingcamango ezisisiseko, eziya kusinceda siqonde. Okokuqala, kufuneka sazi iingcamango ezimbini. Enye kukutshintshana kwemagnetization, eyenzeka kwi-iron core ye-transformer nakwi-stator okanye amazinyo e-rotor yemoto; Enye yipropathi ye-rotary magnetization, eveliswa yi-stator okanye i-rotor joke yemoto. Kukho izinto ezininzi eziqala kumanqaku amabini kwaye zibala ukulahleka kwesinyithi kwemoto ngokusekelwe kwiimpawu ezahlukeneyo ngokwendlela yesisombululo engentla. Uvavanyo lubonise ukuba amaphepha esinyithi e-silicon abonisa ezi zinto zilandelayo phantsi kwe-magnetization yeempawu ezimbini:
Xa uxinano lwe-magnetic flux lungaphantsi kwe-1.7 Tesla, ukulahleka kwe-hysteresis okubangelwa yi-rotating magnetization kukhulu kunoko kubangelwe yi-alternating magnetization; Xa kungaphezulu kwe-1.7 Tesla, okuchaseneyo kuyinyaniso. Uxinano lwe-magnetic flux lwe-motor jock luhlala luphakathi kwe-1.0 kunye ne-1.5 Tesla, kwaye ukulahleka kwe-rotational magnetization hysteresis okuhambelanayo kungaphezulu kwama-45 ukuya kuma-65% kunokulahleka kwe-alternating magnetization hysteresis.
Kakade ke, ezi zigqibo zingasentla nazo ziyasetyenziswa, kwaye andikaziqinisekisi ngokwam xa ndisenza njalo. Ukongeza, xa intsimi yemagnethi kwisiseko sentsimbi itshintsha, umsinga ubangelwa kuwo, obizwa ngokuba yi-eddy current, kwaye ilahleko ezibangelwa yiwo zibizwa ngokuba yi-eddy current losses. Ukuze kuncitshiswe ilahleko yomsinga we-eddy, umsinga wentsimbi yemoto awuqhele ukwenziwa ube yibhloko epheleleyo, kwaye ubekwa nge-axial ngamashiti entsimbi agqunywe nge-insulated ukuthintela ukuhamba kwemisinga ye-eddy. Ifomula ethile yokubala ukusetyenziswa kwentsimbi ayizukuba nzima apha. Ifomula esisiseko kunye nokubaluleka kokubalwa kokusetyenziswa kwentsimbi yeBaidu kuya kucaca kakhulu. Oku kulandelayo luhlalutyo lwezinto ezibalulekileyo ezichaphazela ukusetyenziswa kwentsimbi yethu, ukuze wonke umntu akwazi ukubheka phambili okanye ukubuya umva ingxaki kwizicelo zobunjineli ezisebenzayo.
Emva kokuxoxa ngale nto ingasentla, kutheni ukwenziwa kwesitampu kuchaphazela ukusetyenziswa kwesinyithi? Iimpawu zenkqubo yokubhoboza zixhomekeke kakhulu kwiimo ezahlukeneyo zoomatshini bokubhoboza, kwaye zichonge indlela yokushefa ehambelanayo kunye nenqanaba loxinzelelo ngokweemfuno zeentlobo ezahlukeneyo zemingxuma kunye nemingxunya, ngaloo ndlela kuqinisekiswa iimeko zeendawo zoxinzelelo olungaphantsi komhlaba ezijikeleze umda we-lamination. Ngenxa yobudlelwane phakathi kobunzulu kunye nemilo, idla ngokuchaphazeleka zii-engile ezibukhali, kangangokuba amanqanaba aphezulu oxinzelelo anokubangela ukulahleka okukhulu kwesinyithi kwiindawo zoxinzelelo olungaphantsi komhlaba, ngakumbi kwimiphetho emide yokusika ngaphakathi koluhlu lwe-lamination. Ngokukodwa, kwenzeka ikakhulu kummandla we-alveolar, odla ngokuba yindawo ephambili yophando kwinkqubo yophando yokwenyani. Amaphepha esinyithi e-silicon aphantsi adla ngokumiselwa bubungakanani obukhulu bengqolowa. Impembelelo inokubangela ii-burrs zokwenziwa kunye ne-shear ekrazukileyo kumda osezantsi wephepha, kwaye i-engile yempembelelo inokuba nempembelelo enkulu kubungakanani bee-burrs kunye neendawo zokuguqulwa. Ukuba indawo yoxinzelelo oluphezulu idlula kwindawo yokuguqulwa komda ukuya ngaphakathi kwezinto, isakhiwo sengqolowa kwezi ndawo siya kudlula kutshintsho olufanelekileyo, sijijeke okanye siqhekeke, kwaye ukunwebeka okukhulu komda kuya kwenzeka kwicala lokukrazula. Ngeli xesha, uxinano lomda weenkozo kwindawo yoxinzelelo kwicala lokucheba luya kwanda ngokungenakuphepheka, nto leyo ekhokelela ekwandeni okufanayo kokulahleka kwesinyithi ngaphakathi kommandla. Ke ngoko, ngeli xesha, izinto ezikwindawo yoxinzelelo zinokuthathwa njengezinto ezilahlekileyo kakhulu eziwela phezu kwe-lamination eqhelekileyo ecaleni komphetho wempembelelo. Ngale ndlela, i-constant yokwenyani yezinto ezikumphetho inokumiselwa, kwaye ukulahleka kokwenyani komphetho wempembelelo kunokumiselwa ngakumbi kusetyenziswa imodeli yokulahleka kwesinyithi.
1. Impembelelo yeNkqubo yokuNyula kwiLahleko yeNsimbi
Iimeko zempembelelo yokulahleka kwesinyithi zikho ikakhulu kwicala lamaphepha esinyithi esilicon, kwaye uxinzelelo loomatshini nobushushu luya kuchaphazela amaphepha esinyithi esilicon kunye notshintsho kwiimpawu zawo zokwenyani. Uxinzelelo olongezelelweyo loomatshini luya kukhokelela kutshintsho ekulahlekelweni kwesinyithi. Kwangaxeshanye, ukunyuka okuqhubekayo kobushushu bangaphakathi bemoto kuya kukhuthaza ukwenzeka kweengxaki zokulahleka kwesinyithi. Ukuthatha amanyathelo asebenzayo okususa uxinzelelo olongezelelweyo loomatshini kuya kuba nefuthe elihle ekunciphiseni ukulahleka kwesinyithi ngaphakathi kwemoto.
2. Izizathu zokulahlekelwa kakhulu kwiinkqubo zokuvelisa
Iisheyiti zesinyithi zesilicon, njengezinto eziphambili zemagnethi zeemoto, zinempembelelo enkulu ekusebenzeni kwemoto ngenxa yokuthobela kwazo iimfuno zoyilo.

Le ngxaki idla ngokwenzeka ngexesha lokulungiswa kwe-winding kunye ne-motor ngexesha lenkqubo yokuvelisa kunye nokucubungula.
Ukuwelda nge-stacking kunye nezinye iinkqubo kunokubangela umonakalo kwi-insulation phakathi kwee-stacks, okwandisa ilahleko ye-eddy current.
Ubunzima bentsimbi obunganelanga kunye nokuxinana okungaphelelanga phakathi kwamaphepha. Isiphumo sokugqibela kukuba ubunzima bombindi wentsimbi abanelanga, kwaye isiphumo esithe ngqo kukuba umbane udlula unyamezelo, ngelixa kusenokubakho inyani yokuba ukulahleka kwentsimbi kudlula umgangatho.
Ingubo ekwiphepha lesinyithi lesilicon ityebile kakhulu, nto leyo ebangela ukuba isekethe yemagnethi igcwale kakhulu. Ngeli xesha, ijika lobudlelwane phakathi komsinga ongenamthwalo kunye nevolthi ligobile kakhulu. Oku kukwayinto ebalulekileyo kwinkqubo yokuvelisa nokucubungula amaphepha esinyithi esilicon.
Ngexesha lokuveliswa nokucutshungulwa kweentsimbi zentsimbi, ukujongwa kweenkozo zesinyithi se-silicon steel sheet punching kunye ne-shearing surface attachment kungonakalisa, okukhokelela ekwandeni kokulahleka kwentsimbi phantsi kwe-magnetic induction efanayo; Kwiimoto ezitshintsha-tshintshayo, ukulahleka kwentsimbi eyongezelelweyo okubangelwa yi-harmonics nako kufuneka kuqwalaselwe; Le yinto ekufuneka iqwalaselwe ngokupheleleyo kwinkqubo yoyilo.
Ukongeza kwezi zinto zingasentla, ixabiso loyilo lokulahleka kwesinyithi semoto kufuneka lisekelwe kwimveliso yokwenyani kunye nokucutshungulwa kwesiseko sesinyithi, kwaye kufuneka kwenziwe yonke imizamo ukuqinisekisa ukuba ixabiso lethiyori lihambelana nexabiso lokwenyani. Iigophe zeempawu ezibonelelwa ngababoneleli bezinto eziqhelekileyo zilinganiswa kusetyenziswa indlela ye-Epstein square coil, kodwa ulwalathiso lwemagnetization lwamacandelo ahlukeneyo kwimoto lwahlukile, kwaye olu lahleko lukhethekileyo lwesinyithi olujikelezayo alunakuqwalaselwa okwangoku. Oku kunokukhokelela kumanqanaba ahlukeneyo okungahambelani phakathi kwamaxabiso abaliweyo namanani alinganisiweyo.
