Uphuhliso lweenjini zemagnethi ezisisigxina zihambelana ngokusondeleyo nophuhliso lwezixhobo ezisisigxina zemagnethi.ilizwe lam lilizwe lokuqala emhlabeni ukufumanisa iipropathi zemagneti zezixhobo ezisisigxina zemagnethi kwaye uzisebenzise ukuziqhelanisa.Ngaphezulu kweminyaka engamawaka amabini eyadlulayo, ilizwe lethu lasebenzisa iipropathi zamagnetic zezinto ezizibuthe ezisisigxina ukwenza ikhampasi, edlale indima enkulu ekuhambeni, emkhosini nakweminye imimandla.Iye yaba yenye yezinto ezine eziphambili kwilizwe lam lamandulo.

Izilumkiso zeenjini zemagnethi ezisisigxina

1. Ubume besiphaluka semagnethi kunye nokubala koyilo

Ukuze unike umdlalo opheleleyo kwiipropathi zemagnethi zezixhobo ezahlukeneyo zemagnethi esisigxina, ngakumbi ezona mpawu zibalaseleyo zemagnethi ezinqabileyo zomhlaba ezisisigxina, kunye nokwenza iimotor zemagnethi ezingabizi kakhulu, ulwakhiwo kunye neendlela zokubala zoyilo lweemotor zemagnethi ezisisigxina okanye iinjini zokuvuselela umbane azinakusetyenziswa ngokulula., ingcamango entsha yoyilo kufuneka isungulwe, kwaye ulwakhiwo lwesekethe yamagnetic kufuneka luhlalutywe kwaye luphuculwe.Ngophuhliso olukhawulezayo lwehardware yekhompyuter kunye nobuchwepheshe besoftware, kunye nokuphuculwa okuqhubekayo kweendlela zoyilo lwangoku ezinje ngokubala kwamanani entsimi ye-electromagnetic, uyilo lokuphucula kunye netekhnoloji yokulinganisa, ngeenzame ezidityanelweyo zeziko leemoto kunye noluntu lobunjineli, iye yaxhaphaka. isetyenziswe kwithiyori yoyilo, Inkqubela phambili yoPhuculo lwenziwe kwiindlela zokubala, itekhnoloji yolwakhiwo kunye netekhnoloji yokulawula, njl. njl., kunye neseti yohlalutyo kunye neendlela zophando kunye nohlalutyo oluncediswa yikhompyuter kunye noyilo lwesoftware edibanisa ukubalwa kwamanani kwintsimi ye-electromagnetic kunye nohlalutyo lwesekethe yemagnethi efanayo. isisombululo senziwe, kwaye ziyaphucuka rhoqo..

2. Imiba yokulawula

Injini yemagnethi esisigxina inokugcina intsimi yayo yamagnetic ngaphandle kwamandla angaphandle, kodwa yenza kube nzima kakhulu ukulungelelanisa nokulawula umhlaba wayo wemagnethi ngaphandle.Kunzima kwijeneretha yemagnethi esisigxina ukuba ilungelelanise umbane wayo ophumayo kunye namandla avela ngaphandle, kwaye imagnethi esisigxina yeDC motor ayinakuphinda ilungelelanise isantya sayo ngokuguqula indlela yokuvuselela.Oku kunciphisa usetyenziso lweenjini ezisisigxina zemagnethi.Nangona kunjalo, ngophuhliso olukhawulezayo lwezixhobo zombane zombane kunye nobuchwepheshe bokulawula obunje ngeMOSFETs kunye nee-IGBTs, uninzi lweemotor ezisisigxina zemagnethi zinokusetyenziswa ngaphandle kolawulo lwemagnethi kunye nolawulo lwezixhobo kuphela.Xa uyila, kuyimfuneko ukudibanisa itekhnoloji ezintathu ezintsha zezinto ezinqabileyo zamagnetic emhlabeni, izixhobo zombane zombane kunye nolawulo lwe-microcomputer, ukuze imotor esisigxina yemagnethi isebenze phantsi kweemeko ezintsha zokusebenza.

3. Ingxaki ye-irreversible demagnetization

Ukuba uyilo okanye ukusetyenziswa akufanelekanga, i-motor yemagnethi esisigxina iya kuba phantsi kwesenzo se-armature reaction ebangelwa yi-inrush yangoku xa ubushushu buphezulu kakhulu (i-NdFeB umazibuthe osisigxina) okanye iphantsi kakhulu (imagnethi esisigxina ye-ferrite), okanye xa kukho. ukungcangcazela komatshini obukhali Kuyenzeka ukuba kubangele demagnetization engaguqukiyo, okanye ukulahleka kwemagneti, okuya kunciphisa ukusebenza kwemoto kwaye kuyenze ingasebenziseki.Ke ngoko, kuyafuneka ukuphanda kunye nokuphuhlisa iindlela kunye nezixhobo zokujonga uzinzo lwe-thermal yezixhobo zemagnethi ezisisigxina ezifanelekileyo kubenzi beemoto, kunye nokuhlalutya amandla okulwa ne-demagnetization kwiifom ezahlukeneyo zolwakhiwo, ukuze kuthathwe amanyathelo ahambelanayo okuqinisekisa ukuba ngexesha loyilo. kunye nokwenza.Iinjini zemagnethi ezisisigxina aziphulukani nemagnethi yazo.

4. Imiba yeendleko

Iinjini zemagnethi ezisisigxina zeFerrite, ngakumbi iinjini ezincinci zemagnethi ezisisigxina zeDC, zisetyenziswe ngokubanzi ngenxa yesakhiwo esilula kunye nenkqubo, ubunzima obuncitshisiweyo, kunye nexabiso eliphantsi ngokubanzi kuneenjini zokuvuselela umbane.Kuba iimagnethi zomhlaba ezisisigxina ezinqabileyo zisabiza kakhulu okwangoku, ixabiso leenjini zemagnethi ezisisigxina emhlabeni jikelele ziphezulu kuneemotor ezivuselela umbane, ekufuneka zihlawulwe ngokusebenza kwazo okuphezulu kunye nokonga kweendleko zokusebenza.Kwezinye iimeko, ezifana ne-coil motors ye-computer disk drives, ukusebenza kweemagnethi ezisisigxina ze-NdFeB kuphuculwe, umthamo kunye nobunzima buyancipha kakhulu, kwaye ixabiso lilonke liyancitshiswa.Kuyilo, kuyimfuneko ukuthelekisa ukusebenza kunye nexabiso ngokwezihlandlo ezithile zokusetyenziswa kunye neemfuno zokugqiba ukhetho, kodwa kunye nokuvuselela inkqubo yolwakhiwo kunye nokulungiswa koyilo ukunciphisa iindleko.
