Xa kuthelekiswa neenjini ze-asynchronous motors, iimotor zemagnethi ezisisigxina zineengenelo zamandla aphezulu, ukusebenza kakuhle, ukulinganiswa kweeparamitha ze-rotor, umsantsa omkhulu womoya phakathi kwe-stator kunye ne-rotor, ukusebenza kakuhle kokulawula, ubungakanani obuncinci, ubunzima obulula, isakhiwo esilula, i-torque ephezulu / inertia ratio. , njl. Ziye zasetyenziswa ngokubanzi kwiindawo zepetroleum, imboni yeekhemikhali, i-textile, imigodi, izixhobo zomatshini we-CNC, iirobhothi, njl., kwaye ziphuhlisa ngokubhekiselele kumandla aphezulu (isantya esiphezulu, i-torque ephezulu), ukusebenza okuphezulu kunye ne-miniaturization.
Iimotor ze-synchronous zemagnethi ezisisigxina zenziwe ngeestators kunye neerotors. I-stator iyafana ne-asynchronous motors, equlethwe ngamanqanaba amathathu omoya kunye ne-stator cores. I-pre-magnetized (magnetized) imagnethi esisigxina ifakwe kwi-rotor, kwaye intsimi yamagnetic inokusekwa kwindawo ejikelezileyo ngaphandle kwamandla angaphandle, okwenza lula ukwakhiwa kweemoto kunye nokugcina amandla. Eli nqaku lichaza izibonelelo ezibanzi zokukhuthaza iimotor ezisisigxina zemagnethi ezihambelanayo ezisekwe kwiimpawu zemagnethi ezisisigxina zeemotor synchronous.
1. Iingenelo ezibalaseleyo zemagnethi esisigxina ye-synchronous motor
(1) Ekubeni i-rotor yenziwe ngeemagnethi ezisisigxina, ukuxinana kwemagnethi kuphezulu, akukho mfuneko yokuvuselela, kwaye ilahleko yokuvuselela iyapheliswa. Xa kuthelekiswa ne-asynchronous motors, i-excitation current ye-stator winding kunye nobhedu kunye nokulahlekelwa kwentsimbi ye-rotor iyancitshiswa, kwaye umbane osebenzayo uyancipha kakhulu. Kuba amandla e-stator kunye ne-rotor magnetic adityaniswa, i-rotor core ayinayo ilahleko yentsimbi esisiseko, ngoko ke ukusebenza kakuhle (okunxulumene namandla asebenzayo) kunye nemeko yamandla (enxulumene namandla asebenzayo) iphezulu kuneemotor ezilinganayo. Iimotor ze-synchronous zemagnethi ezisisigxina ziyilwe ngokubanzi ukuba zibe namandla aphezulu kunye nokusebenza kakuhle naxa zisebenza phantsi komthwalo okhanyayo.
Xa izinga lomthwalo weemoto eziqhelekileyo ze-asynchronous zingaphantsi kwe-50%, ukusebenza kwazo ngokufanelekileyo kunye namandla anamandla ehla kakhulu. Xa izinga lomthwalo we-Mingteng isigxina se-magnetic motors synchronous motors yi-25% -120%, ukusebenza kwabo kokusebenza kunye namandla ombane akutshintshi kakhulu, kwaye ukusebenza kakuhle ngu> 90%, kwaye amandla ombane ngu-0.85. Isiphumo sokugcina amandla sibalulekile phantsi komthwalo wokukhanya, umthwalo oguquguqukayo kunye nomthwalo opheleleyo.
(2) Iimotor zemagnethi ezisisigxina zineepropathi zoomatshini eziqinileyo kwaye ziyakwazi ukumelana nokuphazamiseka kwetorque yemoto okubangelwa lutshintsho lomthwalo. I-rotor core ye-magnetic esisigxina ye-synchronous motor inokwenziwa ibe yisakhiwo esingenanto ukunciphisa inertia ye-rotor, kwaye ixesha lokuqalisa kunye ne-braking likhawuleza kakhulu kunelo motor asynchronous. Umlinganiselo ophezulu we-torque / inertia wenza iimotor ezisisigxina zemagnethi ezihambelanayo zifaneleke ngakumbi ukusebenza phantsi kweemeko zokuphendula ngokukhawuleza kuneenjini ze-asynchronous.
(3) Ubungakanani beenjini ezisisigxina zemagnethi ezihambelanayo zincinci kakhulu kuneemotor ezilinganayo, kwaye ubunzima bazo buyelula. Ngeemeko ezifanayo zokulahla ubushushu kunye nezixhobo zokugquma, uxinaniso lwamandla eemotor ezisisigxina zemagnethi ezilungelelanisiweyo zingaphezulu kokuphindwe kabini kunenqanaba lesithathu leenjini ze-asynchronous.
(4) Isakhiwo se-rotor silula kakhulu, ekulula ukusigcina nokuphucula ukuzinza kokusebenza.
Ekubeni i-asynchronous motors ezithathu kufuneka ziyilwe ngamandla aphezulu, isithuba somoya phakathi kwe-stator kunye ne-rotor kufuneka senziwe sincinci kakhulu. Kwangaxeshanye, ukufana kwesikhewu somoya kukwabalulekile ekusebenzeni okukhuselekileyo kunye nengxolo yokungcangcazela kwemoto. Ke ngoko, iimfuno zemilo kunye nokunyamezelana kwesikhundla kunye nokugxilwa kwendibano yemoto ye-asynchronous zingqongqo, kwaye inkululeko yokukhethwa kwemvume yokuthwala incinci. Iinjini zeAsynchronous ezineziseko ezinkulu zihlala zisebenzisa iibheringi zokuthambisa ioyile, ekufuneka zizaliswe ngeoyile yokuthambisa ngaphakathi kwexesha elichaziweyo lokusebenza. Ukuvuza kwe-oyile okanye ukuzaliswa ngokungalindelekanga kwi-oyile ye-oyile kuya kukhawulezisa ukungaphumeleli kwe-bearing. Ekugcinweni kweenjini ze-asynchronous zesigaba sesithathu, ukugcinwa kweebheringi kubangela umlinganiselo omkhulu. Ukongezelela, ngenxa yobukho bokunyanzeliswa kwangoku kwi-rotor ye-asynchronous motor ye-asynchronous phase, ingxaki yokubola kombane we-bearing nayo ixhalabele ngabaphandi abaninzi kwiminyaka yamuva.
Iimotor ze-synchronous zemagnethi ezisisigxina azinazo iingxaki ezinjalo. Ngenxa yesikhewu esikhulu somoya wemagnethi esisigxina ye-synchronous motor, ezi ngxaki zingasentla ezibangelwa ngumsantsa omncinci womoya we-asynchronous motor azibonakali kwi-synchronous motor. Kwangaxeshanye, iibheringi zemagnethi esisigxina ye-synchronous motor zisebenzisa iibheringi ezigalelwe igrisi ezinezigqubuthelo zothuli. Iibheringi zitywinwe ngesixa esifanelekileyo segrisi ekumgangatho ophezulu xa ushiya umzi-mveliso. Ubomi benkonzo yemagnethi esisigxina yeebheringi ze-synchronous motor iphezulu kakhulu kunaleyo ye-asynchronous motor.
Ukuze kuthintelwe i-shaft yangoku ekungcoleni, i-Anhui Mingteng ye-magnetic motor ithatha idizayini ye-insulation ye-insulation yendibano ekupheleni komsila, enokufikelela kwisiphumo sokugquma ukuthwala, kwaye iindleko ziphantsi kakhulu kunezo zokugquma. ukuthwala. Ukuqinisekisa ubomi obuqhelekileyo benkonzo yokuthwala i-motor, inxalenye ye-rotor yazo zonke ii-motor ze-magnetic ezisisigxina ze-synchronous ngqo drive ye-Anhui Mingteng inesakhiwo esikhethekileyo senkxaso, kunye nokutshintshwa kwendawo yeebheringi kufana ne-motor asynchronous. Kamva ukuthwala ukutshintshwa kunye nokugcinwa kunokonga iindleko zolungiselelo, ukonga ixesha lokugcinwa, kunye nokuqinisekisa ngcono ukuthembeka kwemveliso yomsebenzisi.
