Imagnethi eyomeleleyo ye-NdFeB kunye ne-SmCo inokuvelisa amandla okuqhuba ezinye izinto ngaphandle konxibelelwano oluthe ngqo, ke uninzi lwezicelo luthatha eli thuba, ngokufana nokudityaniswa kwemagnethi emva koko iimpompo ezidityaniswe ngomagnetic zosetyenziso olungatywinwanga.I-Magnetic drive couplings inikezela ngokugqithiswa okungadingekiyo kwetorque.Ukusetyenziswa kwezi zidibanisi zemagneti kuya kuphelisa ukuvuza kwamanzi okanye igesi ukusuka kumacandelo enkqubo.Ngaphezu koko, ukudityaniswa kwamagnetic nako kukugcinwa simahla, ngoko ke kuncitshiswa iindleko.
Ingaba iimagnethi zabiwa njani kumdibaniso wempompo kazibuthe ukuze zisebenze?
AbadityanisiweyoNdFeB or SmCoiimagnethi zincanyathiselwe kumakhonkco amabini agxininise kumacala omabini eqokobhe lesithintelo kwindlu yempompo.Iringi yangaphandle idityaniswe kwishaft yemoto yemoto;iringi yangaphakathi kwishaft yempompo.Iringi nganye iqulethe inani elifanayo lemagnethi ezihambelanayo nezichasayo, ezicwangciswe ngeepali ezitshintshanayo ezijikeleze iringi nganye.Ngokuqhuba isiqingatha sokudibanisa sangaphandle, i-torque ihanjiswa ngombane kwisiqingatha sokudibanisa sangaphakathi.Oku kunokwenziwa ngomoya okanye ngesithintelo esingenamagnetic, esivumela ukwahlulwa ngokupheleleyo kweemagnethi zangaphakathi kwiimagnethi zangaphandle.Akukho nxalenye zoqhagamshelwano kwiimpompo zemagnethi zokuqhuba ezivumela ukuhanjiswa kwetorque ngokungahambi kakuhle kwe-angular kunye ne-parallel.
Kutheni le nto i-NdFeB okanye i-SmCo iimagnethi zomhlaba ezinqabileyo zikhethwa kwiimpompo zemagnethi ezidityanisiweyo?
Izixhobo zemagnethi ezisetyenziswa kudibaniso lwemagnethi zihlala zisebenza ngemagnethi yeNeodymium kunye neSamarium Cobalt ngezizathu ezilandelayo:
1. NdFeB okanye SmCo umazibuthe luhlobo lwemagnethi esisigxina, ekulula kakhulu ukuyisebenzisa kunemagnethi ye-electro efuna unikezelo lwamandla lwangaphandle.
2. Imagnethi ye-NdFeB kunye ne-SmCo inokufikelela kumandla aphezulu kakhulu kunemagnethi esisigxina.Imagnethi yeNeodymium sintered ibonelela ngeyona mveliso yamandla iphezulu kuyo nayiphi na imathiriyeli namhlanje.Uxinaniso lwamandla oluphezulu lwenza ukuba ubunzima obukhaphukhaphu besixhobo semagnethi esincinci sifikelele kwimpumelelo ephuculweyo yenkqubo yempompo enobungakanani obubambeneyo.
3. Imagnethi yomhlaba enqabileyo yeCobalt kunye ne-Neo umazibuthe inokusebenza ngozinzo olungcono lobushushu.Kwinkqubo yokusebenza, njengoko ubushushu bokusebenza bukhula okanye ubushushu obuveliswa yi-eddy yangoku, amandla ombane kwaye i-torque iya kuba nokuncipha okuncinci ngenxa ye-coefficients yobushushu obungcono kunye nobushushu obuphezulu bokusebenza be-NdFeB kunye ne-SmCo sintered magnets.Ngolunye ubushushu obukhethekileyo obuphezulu okanye ulwelo oludlekayo, umazibuthe we-SmCo lolona khetho lulungileyo lwemathiriyeli yemagnethi.
Ithini imilo yemagnethi ye-NdFeB okanye ye-SmCo esetyenziswa kuqhagamshelo lwempompo yemagnethi?
I SmCo okanye NdFeB sintered iimagnethi inokuveliswa kuluhlu olubanzi imilo kunye nobukhulu.Ukusetyenziswa kokudibanisa impompo yemagnethi, ubukhulu becala iimilo zemagnethi zivimba, isonkaokanye icandelo le-arc.
Umenzi ophambili wokudityaniswa kwemagnethi esisigxina okanye iimpompo ezidityaniswe ngomagnetic emhlabeni:
