Kutheni le nto iinjini zemagnethi ezisisigxina ziwonga amandla?

Kwiminyaka embalwa edlulileyo, ishishini leemoto xa iprofayili ephezulu yeenjini zemagnethi ezisisigxina, iqondo lokuthandwa libonisa ukukhula okukhulayo. Ngokohlalutyo, isizathu sokuba iinjini zemagnethi ezisisigxina zinokuxhalaba ngokuphindwe kabini, azinakwahlulwa kwinkxaso eyomeleleyo yemigaqo-nkqubo yelizwe ukuya kwiimotor zemagnethi ezisebenza ngokufanelekileyo njengommeli wobuchule obuphezulu, iimveliso zemoto ezinomgangatho ophezulu kakhulu zinokukhawuleza zidume ukunceda ukonga amandla kunye nokunciphisa ukukhutshwa, ukugcina iintaba eziluhlaza kunye namanzi aluhlaza. Ukonga amandla kunye nokukhuselwa kokusingqongileyo kufuneka kube yindlela yophuhliso lwexesha elizayo, ngakumbi kushishino lweemoto, imagnethi esisigxina yogcino lwamandla ibonakalisa iingenelo zayo ngaphandle kwesantya sokugcina amandla inokuba ngaphezulu kwama-20%, kumhlaba onqabileyo onqabileyo wemagnethi esisigxina kwiingenelo zokonga amandla zimi ngolu hlobo lulandelayo:

Imagnethi yomhlaba esisigxina kwiinzuzo ezintandathu zokonga amandla

I-1, i-magnetic motor esisigxina kune-motor yesiqhelo esindisa i-5% -30%, iimeko zokusebenza zezixhobo ezithile zomlinganiselo wokulondoloza amandla ohlukeneyo zahlukile.

2, imagnethi esisigxina ye-synchronous motor ukuphumeza inqanaba lokusebenza kwamandla, ukusebenza kakuhle kwamandla okungaphezulu kwe-95%; Inqanaba lesithathu lenqanaba le-asynchronous motor linamandla amathathu, ukusebenza kakuhle kwamandla kumalunga ne-90%.

3, imagnethi esisigxina ye-synchronous motor rotor inomhlaba onqabileyo wentsimbi yemagnethi esisigxina, ayifuni isitator ukuba ibonelele amandla okungenisa, kunokuba ilahleko yemoto eqhelekileyo incinci;

I-4, imagnethi esisigxina ye-synchronous motor stator lead wire yinkwenkwezi (Y) uxhulumaniso, inokugcina amandla angatshintshanga okwangoku amancinci; iinjini eziqhelekileyo ubukhulu becala △ uqhagamshelo;

I-5, i-magnetic esisigxina ye-synchronous motor kwinkqubo yokusebenza, xa umthwalo utshintsha xa ixabiso lokusetyenziswa kwamandla lihlala lingatshintshi, i-motor ye-asynchronous eqhelekileyo xa umthwalo utshintsha xa ixabiso lokuphumelela kwamandla liza kutshintsha, i-motor eqhelekileyo ye-asynchronous kumthwalo ukuya kwi-quarter-quarter yexabiso lokuphumelela kwamandla ayitshintshi, xa umthwalo ungaphantsi kwe-70% yexabiso lexabiso layo lamandla liya kuwa lithe tye.

I-6, imagnethi esisigxina ye-synchronous motor akukho-mthwalo yangoku incinci, isinye kwishumi kuphela sangoku esilinganisiweyo, ngelixa i-motor ye-asynchronous eqhelekileyo kwi-no-load yangoku ukufikelela kwisinye kwisithathu.

Umhlaba onqabileyo wemagnethi osisigxina amacandelo amathathu amakhulu

1, Rare umhlaba osisigxina umazibuthe motor wamkela high-ukusebenza umazibuthe esisigxina, nto leyo ephelisa excitation yangoku stator okanye rotor inxalenye motor, ngoko ke kuphelisa ilahleko yobhedu yale nxalenye (umoya ilahleko ubushushu);

I-2, ukusetyenziswa kwesakhiwo se-brushless, akukho sakhiwo se-carbon brush yokulahlekelwa ngumatshini, kodwa i-brushless motor ihamba nge-electronic commutation structure ukuqonda ukutshintshwa, nantsi inxalenye yamacandelo e-elektroniki yelahleko, kwaye ugcine ilahleko yomatshini xa kuthelekiswa nexabiso lelahleko lincinci, ngoko ke inxalenye yokuguqulwa kwelahleko kunokulahlekelwa kwelahleko ye-brush motor incinci;

I-3, ukusetyenziswa kwemagnethi yomhlaba esisigxina esebenza ngokuphezulu, kumandla alinganisiweyo kunye nesantya esilinganiselweyo, umthamo wemoto unokwenziwa ube mncinci, ukonga ishidi lensimbi ye-silicon, ukunciphisa ilahleko yentsimbi. Iimoto ezincinci zamandla ezisebenzisa umhlaba onqabileyo wemagnethi esisigxina injini zinokufikelela kufutshane ne-90% esebenzayo, imotor ngokubanzi imalunga nama-75%.

Ukusetyenziswa kwe-PMSM kuye kwaba ngumkhwa kumashishini okugcina amandla, ukunciphisa ukukhutshwa, kunye nokufezekisa uphuhliso lwe-win-win green.
