Ama-Ring Magnets eMoto: Umhlahlandlela Wokusebenzisa i-BLDC, i-Stepper kanye ne-Servo

Impendulo Esheshayo:Kuma-motor e-BLDC, sebenzisa oma-magnets endandatho ye-radial enezinsika eziningi anezinsika ezingu-8-24 ku-N42SH noma i-N45SH grade; kuma-stepper motors, amasongo e-NdFeB ahlanganisiwe anezinsika ezingaphezu kuka-50 noma i-N35SH e-sintered kumadizayini e-hybrid; kuma-servo motors, amasongo e-sintered alinganayo aphezulu (ukuguquguquka kokuguquguquka ngaphansi kuka-±2%) ku-N45SH noma i-N48SH. Zonke izinhlelo zokusebenza zezimoto ezingaphezu kuka-100°C zidinga ibanga le-SH noma le-UH. I-torque ripple enama-magnets endandatho ingu-2-5% uma kuqhathaniswa no-8-15% ngama-arc ahlanganisiwe ahlukene.

Ngokusekelwe kuUbuchwepheshe be-FullzenOkuhlangenwe nakho kwangempela kokukhiqiza kwama-magnets angu-50,000 e-motor ring ngenyanga, iziphetho ezilandelayo zokukhetha ezisebenza ngqo zinikezwa ngohlobo lwe-motor:

Ukuqhathaniswa kwedatha yokusebenza: indandatho vs i-arc ehlukanisiwe

Kungani Ama-Ring Magnets Eyisinqumo Esizenzakalelayo Sokuklama Izimoto Zanamuhla

Omaginethi bendandatho baye bashintsha kancane kancane ama-arc ahlanganisiwe kuma-motor rotors — aqhutshwa yi-torque ripple ephansi, ubuqotho obuhle bomshini, kanye nokuhlanganiswa okulula okunciphisa izindleko ze-rotor eziphelele.

Ekukhetheni i-motor rotor magnet, imboni ishintsha kusuka kuma-arc magnets ahlukaniswe ngokwesiko kuya kuma-monolithic ring magnets. Lo mkhuba awuqondakali nje - uwumphumela wokwenziwa ngcono ngasikhathi sinye ngokusebenza, ukuthembeka, kanye nezindleko.

Indandatho vs I-Arc Ehlukaniswe Ngezigaba: Igebe Lokusebenza

Izinzuzo eziyinhloko zama-ring magnets kunezihlanganisi ze-arc ezihlukanisiwe:

·Ubuqotho bemishini: Omaginethi bendandatho obunjwe ngengxenye eyodwa abanazo izihlanganisi futhi abanayo ingozi yokuqhekeka ngesikhathi sokujikeleza ngesivinini esikhulu. Ama-arcs ahlukaniswe ngezigaba adinga ukubopha okunamathelayo noma ukulungiswa kwemishini, kanti ingozi yokwehluleka ingaphezu kuka-20,000 rpm

·Ukwenza lula ukuhlanganisa: Ama-ring magnets acindezelwa ku-rotor ngesinyathelo esisodwa; ama-arcs ahlukaniswe ngezigaba adinga ukulungiswa kwengxenye ngayinye, ukubopha, kanye nokuhlolwa — umsebenzi wokuhlanganisa wehliswa ngo-50-70%

·Ukusebenza kahle kwesekethe yamagnetic: Omaginethi bendandatho banokugeleza kokuvuza okungaphansi kuka-15%; ama-arcs ahlukaniswe ngezigaba anokuvuza okungu-25-30% emajoyintini — ngezinto ezifanayo, ikhambi lendandatho linikeza ukugeleza okusebenzayo okuphezulu.

Kukhona umkhawulo wezindleko obalulekile: ngaphansi kwamayunithi angu-500 ngenyanga, ama-arcs ahlukaniswe ngezigaba angase abe nezimo eziguquguqukayo (akudingeki i-fixture ye-magnetizing enezinsika eziningi); ngaphezu kwamayunithi angu-500 ngenyanga, inzuzo yokusebenza kahle kokuhlanganiswa kwama-ring magnets offsets fixture amortization, okuholela ekwehleni kwezindleko eziphelele.

· Ukubopha i-carbon fiber: Ama-motor anesivinini esikhulu (>100,000 rpm) adinga isivikelo se-carbon fiber esizungezwe ingaphandle le-rotor

Imibuzo Evame Ukubuzwa

Q: Yisiphi isichasiso se-neodymium ring magnet esivame kakhulu sama-motor e-BLDC?

A: Incazelo evame kakhulu yama-motor e-BLDC indandatho ye-NdFeB enezinsika eziningi enama-radially enezinsika ezingu-8-14 ku-N42SH noma i-N45SH grade, ene-Ni-Cu-Ni coated. Ama-motor e-Inrunner ngokuvamile asebenzisa izinsika ezingu-8-12; ama-motor e-outrunner asebenzisa izinsika ezingu-12-24. Kwa-Fullzen Technology, i-N42SH ithatha ngaphezu kuka-60% wama-oda ethu e-BLDC motor ring magnet ngenxa yebhalansi yayo efanele yamandla kazibuthe kanye nokumelana nokushisa okungu-150°C.

Q: Ingabe omaginethi bendandatho bangathatha indawo yomaginethi be-arc abahlukaniswe ngezigaba emiklamo yezimoto ezikhona?

A: Ezimweni eziningi, yebo. Iswishi ivame ukunciphisa i-torque ripple kusuka ku-8-15% kuya ku-2-5%, ithuthukisa ubuqotho bemishini ye-rotor, futhi yenza kube lula ukuhlangana. Isithiyo esiyinhloko usayizi: omaginethi bendandatho basebenza kahle kakhulu kumadayamitha e-rotor angaphansi kuka-150mm. Kumamotha amakhulu kakhulu angaphezu kuka-200mm OD, ama-arcs ahlukaniswe ngezigaba angase abe wusizo kakhulu. Kwa-Fullzen Technology, iphuzu lokushintshanisa ukusebenza kahle kwezindleko ngokuvamile licishe libe yizingcezu ezingu-500 ngenyanga.

Q: Yiziphi izitifiketi ozidingayo zama-magnets e-EV motor ring?

A: Ama-magnet ezimoto ze-EV adinga isitifiketi sokuphathwa kwekhwalithi ye-IATF 16949, imibhalo ye-PPAP, kanye nokulandelela okugcwele kusukela ezintweni ezingavuthiwe kuya kumkhiqizo oqediwe. Ukuqina kokushisa kubalulekile: iningi lama-motor okudonsa e-EV lisebenza ku-150-180°C njalo, lidinga i-NdFeB engu-40UH noma engu-45UH. Kwa-Fullzen Technology, sigcina amarekhodi agcwele okulandelela futhi sisekela ukuhanjiswa kwe-PPAP Level 3 kumakhasimende ezimoto.

U: Ukuvimbela kanjani ukususwa kwamandla kagesi ezisetshenziswayo zezimoto ezishisa kakhulu?

A: Izici ezintathu ezivimbela ukususwa komagnethi: ukukhetha ibanga elifanele (ibanga le-SH elingu-150°C, i-UH elingu-180°C), imajini eyanele yokucindezela (i-Hcj kufanele idlule insimu yokususwa komagnethi okungenani ngo-30%), kanye nomklamo wokushisa ogcina izinga lokushisa lobuso bemagnethi lingaphansi kwesilinganiso esiphezulu sebanga. Sincoma ukusebenzisa ukuhlaziywa kwejika le-demagnetization ekushiseni kokusebenza okubi kakhulu kwemoto ngaphambi kokuqedela ibanga.

Q: Yisiphi isikhathi esijwayelekile sokuhola sama-magnets endandatho yemoto ngokwezifiso?

A: Amasampula ajwayelekile ngobukhulu obujwayelekile kanye nokuthunyelwa kwebanga le-N42SH zingakapheli izinsuku ezingu-7-10. Imininingwane eyenziwe ngokwezifiso enezihlanganisi ezintsha ze-magnetizing ngokuvamile idinga izinsuku ezingu-15-25 zamasampula okuqala. Isikhathi sokuhola sokukhiqiza ngobuningi siyizinsuku ezingu-15-20 ngemuva kokuvunyelwa kwesampula, kuye ngobuningi be-oda kanye nobunzima. Amasongo amaningi anezingodo ezingaphezu kuka-24 adinga isikhathi esengeziwe sokuhola. Kwa-Fullzen Technology, sigcina isitoko sezinto zokusetshenziswa ezivamile ukuze sinciphise ukuguquguquka kwesikhathi sokuhola.
