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 ngokugqibeleleyo njengommeli wobuchule obuphezulu, iimveliso zemoto ezinobuganga obuphezulu zinokukhawuleza. ethandwayo ukunceda ukonga amandla kunye nokunciphisa ukukhutshwa, ukugcina iintaba eziluhlaza kunye namanzi aluhlaza. Ugcino lwamandla kunye nokhuseleko lokusingqongileyo kufuneka lube yindlela yophuhliso lwexesha elizayo, ngakumbi kushishino lweemoto, imagnethi esisigxina yogcino lwamandla abonisa iingenelo zayo kwisantya sokugcina amandla inokuba ngaphezulu kwama-20%, kumhlaba onqabileyo wemagnethi esisigxina yamandla. -izibonelelo zokulondoloza zezi zilandelayo:

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 lokusebenzisa amandla, ukusebenza kakuhle kwamandla ngaphezu kwe-95%; Inqanaba lesithathu 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 lokuphumelela kwamandla lihlala lingatshintshi, i-motor ye-asynchronous eqhelekileyo xa umthwalo utshintsha xa ixabiso lokuphumelela kwamandla liza kutshintsha, i-asynchronous motor eqhelekileyo kumthwalo ukuya kwiikota ezintathu. Ixabiso lokuphumelela kwamandla alitshintshi, xa umthwalo ungaphantsi kwe-70% yexabiso lexabiso layo lamandla liya kuwa ngqo phantsi.

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 esisigxina yamacandelo 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 sebrashi yekhabhoni yokulahleka komatshini, kodwa i-brushless motor ihamba nge-electronic commutation structure ukuqonda ukutshintshwa, nantsi inxalenye yamacandelo e-elektroniki yelahleko, kwaye ugcine ilahleko yomatshini xa kuthelekiswa. kwixabiso 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% yokusebenza kakuhle, imotor ngokubanzi imalunga nama-75%.

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