· Kwiimeko ezigqithisileyo, ukukhutshwa kwemagnethi → ukutshatyalaliswa kwemoto

Amanyathelo okuthintela:

· Uyilo lokuphazamiseka kokulingana: Gcina ukuphazamiseka okufanelekileyo (ngesiqhelo yi-0.01-0.03mm) phakathi kwe-magnet OD kunye ne-rotor ID

· I-Epoxy resin potting: Zalisa umsantsa phakathi kwemagnethi kunye ne-rotor nge-epoxy resin, enika zombini ukulungiswa kunye nokuhanjiswa kobushushu.

· Ukubopha ifayibha yekhabhoni: Iimoto ezinesantya esiphezulu kakhulu (>100,000 rpm) zifuna isingxobo sefayibha yekhabhoni esijikelezwe ngaphandle kwerotor

FAQ

Q: Yeyiphi eyona nkcazelo ixhaphakileyo yemagnethi yeringi ye-neodymium kwiimoto ze-BLDC?

A: Eyona nkcazelo ixhaphakileyo kwiimoto ze-BLDC yiringi ye-NdFeB enezibonda ezininzi enemitha ye-radially enemitha ye-8-14 kwi-N42SH okanye kwi-N45SH grade, ene-Ni-Cu-Ni coated. Iimoto ze-Inrunner zihlala zisebenzisa izibonda ze-8-12; iimoto ze-outrunner zisebenzisa izibonda ze-12-24. KwiFullzen Technology, i-N42SH ithatha ngaphezulu kwe-60% yee-odolo zethu zemagnethi ye-BLDC ngenxa yokulinganisela kwayo amandla emagnethi kunye nokumelana nobushushu be-150°C.

Q: Ngaba iimagnethi zeringi zinokuthatha indawo yeemagnethi ze-arc ezihlukaniswe ngokwezigaba kwiindlela ezikhoyo zoyilo lweemoto?

A: Kwiimeko ezininzi, ewe. Iswitshi idla ngokunciphisa i-torque ripple ukusuka kwi-8-15% ukuya kwi-2-5%, iphucula i-rotor mechanical intelligence, kwaye yenza kube lula ukuhlanganisana. Umqobo ophambili bubungakanani: ii-ring magnets zezona zibiza kakhulu kwiidayamitha ze-rotor ezingaphantsi kwe-150mm. Kwiimoto ezinkulu kakhulu ezingaphezu kwe-200mm OD, ii-arcs ezihlukanisweyo zisenokuba luncedo ngakumbi. KwiFullzen Technology, indawo yokudlula kwi-crossover yokusebenza kakuhle kweendleko idla ngokuba malunga neziqwenga ezingama-500 ngenyanga.

Q: Zeziphi iziqinisekiso ozifunayo kwiimagnethi zeringi yemoto ye-EV?

A: Iimagnethi zeemoto ze-EV zifuna isiqinisekiso solawulo lomgangatho we-IATF 16949, uxwebhu lwe-PPAP, kunye nokulandeleka kwebhetshi epheleleyo ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo. Uzinzo lobushushu lubalulekile: uninzi lweemoto zokudonsa ze-EV zisebenza kwi-150-180°C ngokuqhubekayo, zifuna i-40UH okanye i-45UH grade NdFeB. KwiFullzen Technology, sigcina iirekhodi ezipheleleyo zokulandeleka kwaye sixhasa ukuhanjiswa kwePPAP Level 3 kubathengi beemoto.

Q: Ukuthintela njani ukususwa kwemagnetization kwizicelo zeemoto ezinobushushu obuphezulu?

A: Izinto ezintathu ezithintela i-demagnetization: ukhetho oluchanekileyo lwebanga (i-SH grade ye-150°C, i-UH ye-180°C), umda ofanelekileyo we-coercivity (i-Hcj kufuneka idlule intsimi ye-demagnetization ubuncinane nge-30%), kunye noyilo lobushushu olugcina ubushushu bomphezulu wemagnethi bungaphantsi komlinganiselo ophezulu webanga. Sicebisa ukuba kuqhutywe uhlalutyo lwe-demagnetization curve kubushushu bokusebenza obubi kakhulu bemoto ngaphambi kokuba kugqitywe i-grade.

Q: Lingakanani ixesha eliqhelekileyo lokukhokela iimagnethi zeringi yemoto eyenziwe ngokwezifiso?

A: Iisampuli eziqhelekileyo ngobukhulu obuqhelekileyo kunye nokuthunyelwa kwenqanaba le-N42SH ngaphakathi kweentsuku ezi-7-10. Iinkcukacha ezenziwe ngokwezifiso ezinezixhobo ezintsha zemagnetizing zihlala zifuna iintsuku ezili-15-25 kwiisampuli zokuqala. Ixesha lokuvelisa ngobuninzi liziintsuku ezili-15-20 emva kokuvunywa kwesampuli, kuxhomekeke kubungakanani be-odolo kunye nobunzima. Iindandatho zeepali ezininzi ezineepali ezingama-24+ zifuna ixesha elongezelelweyo lokufakelwa. KwiFullzen Technology, sigcina isitokhwe sezinto eziqhelekileyo zokwenziwa ukuze sinciphise ukuguquguquka kwexesha lokufakelwa.
