Eyona ndawo inkulu yesicelo yeiimagnethi zomhlaba ezinqabileyo ezisisigxinaziinjini zemagnethi ezisisigxina, ezaziwa ngokuba ziimotor.
IiMotor ngengqiqo ebanzi ziquka iimotor eziguqula amandla ombane abe ngamandla oomatshini kunye neejenereyitha eziguqula amandla oomatshini abe ngamandla ombane.Zombini ezi ntlobo zeenjini zixhomekeke kumgaqo wokungeniswa kwe-electromagnetic okanye amandla ombane njengomgaqo wabo osisiseko.I-air-gap magnetic field iyimfuneko ekusebenzeni kwemoto.I-motor eyenza i-air-gap magnetic field ngokusebenzisa i-excitation ibizwa ngokuba yi-motor induction, ngelixa i-motor eyenza i-air-gap magnetic field ngokusebenzisa imagnethi esisigxina ibizwa ngokuba yimagnethi esisigxina.
Kwi-motor yemagnethi esisigxina, i-air-gap magnetic field yenziwa yimagnethi esisigxina ngaphandle kwesidingo samandla ombane ongezelelweyo okanye i-windings eyongezelelweyo.Ke ngoko, ezona zibonelelo zikhulu zeenjini zemagnethi ezisisigxina ngaphezulu kweemotor zokungeniswa kukusebenza okuphezulu, ukonga amandla, ubungakanani obubambeneyo, kunye nolwakhiwo olulula.Ke ngoko, iimotor zemagnethi ezisisigxina zisetyenziswa ngokubanzi kwiimotor ezahlukeneyo ezincinci kunye ezincinci.Lo mzobo ungezantsi ubonisa imodeli yokusebenza eyenziwe lula yemagnethi esisigxina ye-DC motor.Iimagnethi ezimbini ezisisigxina zivelisa intsimi yamagnetic embindini wekhoyili.Xa ikhoyili inikwe amandla, ifumana amandla e-electromagnetic (ngokomthetho wesandla sasekhohlo) kwaye ijikeleza.Inxalenye ejikelezayo kwimoto yombane ibizwa ngokuba yi-rotor, ngelixa indawo emileyo ibizwa ngokuba yi-stator.Njengoko kunokubonwa kumfanekiso, iimagnethi ezisisigxina ze-stator, ngelixa iikhoyili ze-rotor.
Kwiimoto ezijikelezayo, xa umazibuthe osisigxina iyi-stator, idla ngokudityaniswa kuqwalaselo #2, apho iimagnethi zincanyathiselwe kwindlu yemoto.Xa imagnethi esisigxina iyi-rotor, ngokuqhelekileyo ihlanganiswe kuqwalaselo #1, kunye neemagnethi ezifakwe kwi-rotor core.Kungenjalo, uqwalaselo #3, #4, #5, kunye ne-#6 lubandakanya ukufakela imagnethi kumbindi werotor, njengoko kubonisiwe kumzobo.
Kwiimotor ezihambelanayo, iimagnethi ezisisigxina ngokuyintloko zikwimo yezikwere kunye neeparalelograms.Ukongeza, iinjini ze-cylindrical linear zisebenzisa iimagnethi ze-axially annular.
Iimagnethi kwiMoto yeMagnet eSisigxina zinezi mpawu zilandelayo:
1. Ubume abunzima kakhulu (ngaphandle kwezinye ii-motor micro, ezifana ne-VCM motors), ngokukodwa kwi-rectangular, trapezoidal, i-fan-shaped, kunye neefom zesonka.Ngokukodwa, kwindawo yokunciphisa iindleko zoyilo lweemoto, uninzi luya kusebenzisa iimagnethi ezisikweri ezifakwe ngaphakathi.
2. Imagnethi ilula ngokwentelekiso, ubukhulu becala i-pole-pole magnetization, kwaye emva kokudibanisa, yenza isekethe yemagnethi eneepali ezininzi.Ukuba ingumsesane opheleleyo, ofana ne-neodymium iron boron ring okanye i-hot-pressed ring, ihlala ithatha i-multi-pole radiation magnetization.
3. Ingundoqo yeemfuno zobuchwepheshe ikakhulu ilele ekuzinzeni kobushushu obuphezulu, ukuguquguquka kwemagnethi, kunye nokuguquguquka.Iimagnethi zerotor ezibekwe phezulu zifuna iipropathi ezifanelekileyo zokuncamathelisa, iimagnethi zemoto ezineemfuno eziphezulu zokutshiza ityuwa, iimagnethi zejeneretha yamandla omoya zineemfuno ezingqongqo zokutshiza ityuwa, kwaye iimagnethi zemoto zokuqhuba zifuna uzinzo oluphezulu lobushushu.
4. Iimveliso zamandla kazibuthe eziphakamileyo, eziphakathi, nezisezantsi zisetyenziswa zonke, kodwa ukunyanzeliswa ubukhulu becala kukwinqanaba eliphakathi ukuya phezulu.Okwangoku, amanqanaba emagnethi aqhelekileyo asetyenziswayo kwiimotor zokuqhuba isithuthi sombane ikakhulu ziimveliso zamandla kazibuthe kunye nokunyanzeliswa okuphezulu, okunje nge-45UH, 48UH, 50UH, 42EH, 45EH, njl., kunye netekhnoloji yokusasazwa okuqolileyo kubalulekile.
5. I-segmented adhesive adhesive magnets e-laminated isetyenziswe ngokubanzi kwiindawo ezinobushushu obuphezulu.Injongo kukuphucula ukugqunywa kwecandelo lemagnethi kunye nokunciphisa ilahleko yangoku ye-eddy ngexesha lokusebenza kwemoto, kwaye abanye oomazibuthe banokongeza i-epoxy coating kumphezulu ukunyusa ukugquma kwabo.
Izinto eziphambili zovavanyo lwemagnethi yemoto:
1. Uzinzo lobushushu obuphezulu: Abanye abathengi bafuna ukulinganisa ukubola kwemagnethi evulekileyo, ngelixa abanye bafuna ukulinganisa ukubola kwemagnethi evulekileyo.Ngexesha lokusebenza kwemoto, iimagnethi kufuneka zimelane namaqondo obushushu aphezulu kunye nokutshintshana kwemagnethi.Ke ngoko, uvavanyo kunye nokubeka iliso kwimveliso egqityiweyo ukubola kwemagnethi kunye nobushushu obuphezulu be-demagnetization curves yezinto ezisisiseko ziyimfuneko.
2. Ukuhambelana kwemagnetic flux: Njengomthombo wamandla omagnetic we-motor rotors okanye i-stators, ukuba kukho ukungahambelani kwi-magnetic flux, kunokubangela ukunyakaza kwemoto, kunye nokunciphisa amandla, kwaye kuchaphazele umsebenzi jikelele wemoto.Ke ngoko, iimagnethi zeemoto ngokubanzi zineemfuno zokungaguquguquki kwemagnethi, ezinye zingaphakathi kwe-5%, ezinye zingaphakathi kwe-3%, okanye nakwi-2%.Izinto ezichaphazela ukuguquguquka kwemagnethi, njengokungaguquguquki kwentsalela umazibuthe, ukunyamezelana, kunye nokwaleka kwe-chamfer, zonke kufuneka ziqwalaselwe.
3. Ukuguquguquka: Iimagnethi ezibekwe phezu komphezulu ubukhulu becala zikwimo yeethayile.Iindlela eziqhelekileyo zokuvavanya ii-engile kunye nerediya zinokuba neempazamo ezinkulu okanye kube nzima ukuzivavanya.Kwiimeko ezinjalo, kufuneka kuqwalaselwe ukuba bhetyebhetye.Kwiimagnethi ezilungelelaniswe ngokusondeleyo, izithuba ezongezelekayo kufuneka zilawulwe.Kwimagnethi eneendawo zokubeka i-dovetail, ukuqina kwendibano kufuneka kuthathelwe ingqalelo.Kungcono ukwenza izinto ezimile ngokwesiko ngokwendlela yokuhlanganisa yomsebenzisi ukuvavanya ukuguquguquka kweemagnethi.
