Ngenxa yeempawu zayo ezintle zomzimba, iipropathi ezigqwesileyo zeekhemikhali kunye neepropathi ezilungileyo zenkqubo,izixhobo zemagnethizisetyenziswa kakhulu kwiindawo ezichanekileyo zemoto, eziphucula kakhulu ukusebenza kakuhle kwamalungu eemoto. Imathiriyeli yemagnethi yeyona nto ingundoqo yemoto yokuqhuba izithuthi zamandla amatsha. Ukufakelwa kombane kube ngumkhombandlela wophuhliso lweshishini leemoto kwihlabathi, kwaye imakethi yemagnethi inendawo enkulu. Ukongeza, iChina inowona vimba mkhulu wemithombo yomhlaba enqabileyo emhlabeni. I-China inoovimba abakhulu bemithombo yomhlaba enqabileyo, imveliso enkulu kunye neendleko kunye nezibonelelo zezibonelelo. Ngophuhliso lweshishini elitsha leemoto laseTshayina, izixhobo zemagneti ezikwisiphelo esiphezulu kunye nokufika kweendawo ezifunwayo ziya kuba yindawo entsha yokukhula kolu shishino kwixesha elizayo.
Kwi-lowstream yokusetyenziswa kokusetyenziswa kwezinto eziphathekayo, ukusetyenziswa kwe-China iyonke i-akhawunti malunga ne-50%. Kwisakhiwo semfuno yehlabathi jikelele yezinto eziphezulu zokusebenza zamagnetic, ii-automotive akhawunti ze-52%.
Imoto yokuqhuba yenye yezinto ezintathu eziphambili zezithuthi zamandla amatsha. Isixhobo samagnetic sesona sixhobo siphambili se-stator kunye ne-rotor yemoto yokuqhuba. Ngokwedatha yoMphathiswa wezoShishino kunye netekhnoloji yolwazi yaseTshayina, ngoDisemba ka-2019, umthamo ofakiweyo weenjini zokuqhuba zasekhaya e-China ufikelele kwi-1.24 yezigidi, apho iimotor zemagnethi ezisisigxina zibalelwa kwi-99% yesabelo semarike. Imagnethi esisigxina ye-synchronous motor yenziwa ikakhulu sistator, rotor kunye nokujikajika, isigqubuthelo sokuphela kunye nezinye izakhiwo zoomatshini. Umgangatho kunye nokusebenza kwemathiriyeli kazibuthe imisela ngokuthe ngqo izalathisi eziphambili ezifana nokusebenza kakuhle kwamandla kunye nokuzinza kwemagnethi esisigxina yemoto.
Imathiriyeli yemagnethi yeemoto isetyenziswa ukuqhuba iimotor zezithuthi zamandla amatsha. Imoto yokuqhuba izithuthi zamandla amatsha ngumatshini ohambayo we-electromagnetic osebenza kumgaqo wokungeniswa kombane. Isetyenziselwa ukuguqula amandla ombane kumandla omatshini kunye nokufunxa amandla ombane kwinkqubo yombane ngexesha lokusebenza. Imveliso amandla oomatshini kwinkqubo yoomatshini. Imagnethi esisigxina ebuyela umva imoto yenziwa ikakhulu sistator, rotor kunye nokujikajika, isigqubuthelo sokugqibela kunye nezinye izakhiwo zoomatshini. Phakathi kwazo, umgangatho kunye nokusebenza kwe-stator kunye ne-rotor cores ichaza ngokuthe ngqo ixabiso lezalathisi eziphambili ezifana nokusebenza kwamandla kunye nokuzinza kwe-motor drive, i-accounting ye-19% kunye ne-11% yexabiso lilonke le-magnetic synchronous motor ngokulandelelanayo. Izinto zemagneti zisetyenziswa ikakhulu kwiirotha zeemoto. Ukusuka kwicala lezinto ezibonakalayo, izixhobo zemagneti kunye namaphepha entsimbi yesilicon zezona zinto zibalulekileyo ezimisela ixabiso lemagnethi esisigxina ye-synchronous motor, ibalwa kwi-30% kunye ne-20% yeendleko zizonke ngokulandelelanayo.
Okwangoku, iintlobo zeenjini zokuqhuba ezisetyenziswa kwizithuthi zamandla amatsha ikakhulu ziimotor ze-AC ezingatshintshiyo kunye neemotor ezisisigxina zemagnethi. Ibonisa indlela eyandayo unyaka nonyaka. Njengomthombo wamandla wezithuthi zamandla amatsha, imagnethi esisigxina ye-synchronous motor (PMSM) ineempawu zokuxinana kwamandla aphezulu, ukusebenza okuthembekileyo kunye nokusebenza kwesantya esilungelelanisiweyo, xa kuthelekiswa nezinye iintlobo zeemoto. Inokubonelela ngemveliso enkulu yamandla phantsi kobunzima obufanayo kunye nomthamo, kwaye luhlobo olufanelekileyo lweemoto kwizithuthi zamandla amatsha. Phakathi kwabo, iJapan kunye noMzantsi Korea bamkela umatshini osisigxina wemagnethi, kwaye iYurophu yamkela umatshini we-AC asynchronous. Imagnethi esisigxina ye-synchronous motor (PMSM) ibe ngowona matshini wokuthengisa usetyenziswa kakhulu kwizithuthi zamandla amatsha eTshayina ngenxa yamandla ayo aphezulu, amandla aphantsi, ubungakanani obuncinci kunye nobunzima.
