Ekubeni ukuhanjiswa kwelahleko yemoto kuyahluka kunye nobukhulu bamandla kunye nenani leepali, ukwenzela ukunciphisa ilahleko, kufuneka sigxininise ekuthatheni amanyathelo amacandelo elahleko aphambili amagunya ahlukeneyo kunye neenombolo zepali. Ezinye iindlela zokunciphisa ilahleko zichazwe ngokufutshane ngolu hlobo lulandelayo:

1. Ukwandisa izinto ezisebenzayo zokunciphisa ilahleko yomoya kunye nokulahleka kwentsimbi

Ngokomgaqo wokufana kweenjini, xa umthwalo we-electromagnetic uhlala ungatshintshi kwaye ilahleko yoomatshini ingathathelwa ngqalelo, ilahleko yemoto iphantse yalingana netyhubhu yobungakanani bomgca wemoto, kwaye amandla okufaka imotor aphantse alingane. ngokomlinganiselo wesine amandla obungakanani bomgca. Ukusuka koku, ubudlelwane phakathi kobuchule kunye nokusetyenziswa kwemathiriyeli okusebenzayo kunokuqikelelwa. Ukuze ufumane indawo enkulu phantsi kweemeko ezithile zobukhulu bofakelo ukwenzela ukuba kubekwe izinto ezisebenzayo ngakumbi ukuze kuphuculwe ukusebenza kakuhle kwemoto, ubukhulu bedayamitha yangaphandle ye-stator punching iba yinto ebalulekileyo. Kuluhlu lwesiseko somatshini ofanayo, iinjini zaseMelika zinemveliso enkulu kuneenjini zaseYurophu. Ukuququzelela ukutshatyalaliswa kobushushu kunye nokunciphisa ukunyuka kwamaqondo obushushu, iinjini zaseMelika zihlala zisebenzisa i-stator punching ezinobubanzi obukhulu bangaphandle, ngelixa iinjini zaseYurophu zisebenzisa i-stator punchings kunye needamitha ezincinci zangaphandle ngenxa yesidingo sezinto eziphuma kulwakhiwo ezifana neenjini zobungqina bokudubula kunye nokunciphisa isixa sobhedu esisetyenziswe ekupheleni kokujija kunye neendleko zokuvelisa.

2. Sebenzisa izixhobo ezingcono zamagnetic kunye nenkqubo yokunciphisa ilahleko yentsimbi

Iipropathi zemagneti (ukungena kwemagneti kunye nokulahleka kwentsimbi yeyunithi) yezinto eziphambili zinempembelelo enkulu ekusebenzeni kunye nokunye ukusebenza kwemoto. Ngexesha elifanayo, ixabiso lezinto eziphambili ziyinxalenye ephambili yeendleko zemoto. Ke ngoko, ukhetho lwezixhobo ezifanelekileyo zemagneti sisitshixo sokuyila kunye nokwenza iimotor ezisebenza ngokufanelekileyo. Kwiimotor ezinamandla aphezulu, ilahleko yentsimbi yenza umlinganiselo omkhulu welahleko iyonke. Ke ngoko, ukunciphisa ixabiso leyunithi yelahleko yezinto eziphambili kuya kunceda ukunciphisa ilahleko yentsimbi yemoto. Ngenxa yoyilo kunye nokuveliswa kwemoto, ilahleko yentsimbi yemoto idlula kakhulu ixabiso elibalwe ngokwexabiso lelahleko yentsimbi ebonelelwa yintsimbi yentsimbi. Ngoko ke, ixabiso lelahleko yentsimbi ngokuqhelekileyo linyuswe ngamaxesha angama-1.5 ~ 2 ngexesha lokuyila ukuqwalasela ukwanda kwelahleko yentsimbi.

Esona sizathu siphambili sokunyuka kwelahleko yentsimbi kukuba ixabiso lelahleko yentsimbi yentsimbi yentsimbi ifunyenwe ngokuvavanya isampulu yezinto zestrip ngokwendlela yesangqa se-Epstein yesikwere. Nangona kunjalo, izinto eziphathekayo ziphantsi koxinzelelo olukhulu emva kokubetha, ukucheba kunye ne-laminating, kwaye ilahleko iya kwanda. Ukongeza, ubukho slot izinyo kubangela izikhewu umoya, nto leyo ekhokelela ilahleko akukho-mthwalo kumphezulu engundoqo obangelwa intsimi kazibuthe harmonic izinyo. Oku kuya kukhokelela ekonyukeni okukhulu kwilahleko yentsimbi yemoto emva kokuba yenziwe. Ngoko ke, ngaphezu kokukhetha izixhobo zamagnetic kunye neyunithi yokulahlekelwa kwentsimbi ephantsi, kuyimfuneko ukulawula uxinzelelo lwe-lamination kunye nokuthatha amanyathelo ayimfuneko okunciphisa ukulahleka kwentsimbi. Ngokubhekiselele kwixabiso kunye nenkqubo yezinto, i-high-grade silicon sheet sheets kunye ne-silicon steel sheets encinci kune-0.5mm ayisetyenziswanga kakhulu ekuveliseni ii-motor eziphezulu. Amaphepha entsimbi ombane asezantsi-carbon silicon-free okanye aphantsi-silicon ebandayo-role i-silicon sheet sheet zisetyenziswa ngokubanzi. Abanye abavelisi beenjini ezincinci zaseYurophu baye basebenzisa i-silicon-free steel sheet sheets kunye neyunithi yokulahlekelwa kwexabiso lentsimbi ye-6.5w / kg. Kwiminyaka yakutshanje, iintsimbi zentsimbi ziphehlelele i-Polycor420 iishiti zentsimbi zombane ezine-avareji yeyunithi yelahleko ye-4.0w/kg, nangaphantsi kunamashiti entsimbi ephantsi-silicon. Izinto eziphathekayo nazo zinokugqithiswa kwemagneti ephezulu.

Kwiminyaka yakutshanje, iJapan iye yaphuhlisa i-silicon ephantsi eqengqelekayo yentsimbi enenqanaba le-50RMA350, enomthamo omncinci we-aluminiyam kunye neentsimbi ezinqabileyo zomhlaba ezongeziweyo ekubunjweni kwayo, ngaloo ndlela igcina amandla ombane aphezulu ngelixa inciphisa ilahleko. Ixabiso lelahleko yeyunithi yi-3.12w / kg. Ezi zinokuthi zibonelele ngesiseko esihle semathiriyeli kwimveliso kunye nokukhuthazwa kweenjini eziphezulu.

3. Nciphisa ubungakanani befeni ukunciphisa ilahleko yokuphuma komoya

Kumandla amakhulu e-2-pole kunye nee-4-pole motors, i-wind friction yenza umlinganiselo omkhulu. Umzekelo, ukungqubana komoya kwe-90kW 2-pole motor inokufikelela malunga ne-30% yelahleko iyonke. Umoya wokukhuhlana ubukhulu becala yenziwe ngamandla asetyenziswa yifeni. Kuba ilahleko yobushushu yeenjini ezisebenza kakuhle kakhulu isezantsi, umthamo womoya wokupholisa unokuncitshiswa, kwaye ke amandla okungena komoya nawo anokwehliswa. Amandla okungena komoya aphantse alingane ne-4th ukuya kwi-5th amandla obubanzi befan. Ke ngoko, ukuba ukunyuka kweqondo lobushushu kuvuma, ukunciphisa ubungakanani befeni kunganciphisa ngokufanelekileyo ukungqubana komoya. Ukongeza, uyilo olufanelekileyo lwesakhiwo sokungenisa umoya lukwabalulekile ekuphuculeni ukusebenza kakuhle komoya kunye nokunciphisa ukungqubana komoya. Uvavanyo lubonise ukuba ukukhuhlana komoya kumandla aphezulu e-2-pole inxalenye yemoto esebenza kakuhle kakhulu inokuncitshiswa malunga ne-30% xa kuthelekiswa neenjini eziqhelekileyo. Ekubeni ilahleko yokuphuma komoya iyancipha kakhulu kwaye ayifuni iindleko ezongezelelweyo, ukutshintsha idizayini yefeni kudla ngokuba lelinye lamanyathelo aphambili athathwe kule nxalenye yeenjini eziphezulu.

4. Ukunciphisa ilahleko elahlekileyo ngokuyila kunye namanyathelo enkqubo

Ilahleko elahlekileyo yeenjini ze-asynchronous ibangelwa ikakhulu yilahleko ephezulu-frequency kwi-stator kunye ne-rotor cores kunye ne-windings ebangelwa yi-harmonics ye-high-order ye-magnetic field. Ukunciphisa ilahleko elahlekileyo yomthwalo, i-amplitude ye-harmonic yesigaba ngasinye ingancitshiswa ngokusebenzisa i-Y-Δ series-connected sinusoidal windings okanye enye i-low-harmonic windings, ngaloo ndlela inciphisa ilahleko elahlekileyo. Uvavanyo lubonise ukuba ukusetyenziswa kwe-sinusoidal windings kunokunciphisa ilahleko elahlekileyo ngaphezu kwe-30% ngokuqhelekileyo.

5. Ukuphucula inkqubo ye-die-casting ukunciphisa ilahleko ye-rotor

Ngokulawula uxinzelelo, ubushushu kunye nendlela yokukhutshwa kwegesi ngexesha le-rotor aluminium yokuphosa inkqubo, igesi kwimivalo ye-rotor ingancitshiswa, ngaloo ndlela iphucula i-conductivity kunye nokunciphisa ukusetyenziswa kwe-aluminium ye-rotor. Kwiminyaka yakutshanje, iUnited States iye yaphuhlisa ngempumelelo izixhobo zobhedu zobhedu kunye neenkqubo ezihambelanayo, kwaye ngoku iqhuba imveliso yovavanyo oluncinci. Izibalo zibonisa ukuba ukuba ii-rotors zethusi zithatha indawo ye-aluminium rotors, ilahleko ye-rotor ingancitshiswa malunga ne-38%.

6. Faka isicelo soyilo lwekhompyuter ukunciphisa ilahleko kunye nokuphucula ukusebenza kakuhle

Ukongeza kwizinto ezikhulayo, ukuphucula ukusebenza kwezinto kunye nokuphucula iinkqubo, uyilo lokulungiswa kwekhompyutheni lusetyenziselwa ukumisela ngokufanelekileyo iiparitha ezahlukeneyo phantsi kwemiqathango yeendleko, ukusebenza, njl., ukwenzela ukuba kufumaneke ukuphucuka okukhulu kunokwenzeka ekusebenzeni kakuhle. Ukusetyenziswa koyilo lokuphucula kunokunciphisa kakhulu ixesha loyilo lweemoto kunye nokuphucula umgangatho woyilo lweemoto.
