Fa'aaogāga NdFeB Maneta Tumau I Ta'avale Malosi Fou

2022-12-29

I i le taimi nei, NdFeB ua faʻaaogaina lautele i fanua eseese, e pei o robots, afi fale gaosimea, mea faigaluega fale, taliga taliga, ma isi aso o le a tatou fa'alauiloa le fa'aogaina o maneta tumau NdFeB i ta'avale malosi fou. O ta'avale malosi fou e masani ona aofia ai ta'avale hybrid ma ta'avale eletise mama. O meafaitino maneta tumau NdFeB maualuga e masani ona faʻaaogaina i le taʻavale afi o taavale malosi fou. Ave afi e talafeagai mo taavale fou malosi e aofia ai maneta tumau synchronous motors, AC asynchronous motors ma fesuia'i maneta i totonu oi latou, o le maneta tumau synchronous afi ei ai avea ma afi autu ona o lona lautele saoasaoa laina, malosi maualuga density, laʻititi laʻititi, ma maualuga le lelei. NdFeB maneta tumau ei ai le uiga o oloa malosi maneta maualuga, malosi faʻamalosi faʻamalosi ma le maualuga remanence, lea e mafai ona faʻaleleia lelei le malosi ma le malosi density o afi, ma o loʻo faʻaaogaina lautele i rotors afi maneta tumau.

 

EPS (Electric Power Steering System) o le vaega lea e faʻaaogaina le sili ona tumau maneta (0.25kg/taavale) fa'aopoopo i le afi ta'avale. Le fesoasoani malosi micromotor i le EPS o se afi maneta tumau, lea e maualuga manaoga mo faatinoga, mamafa ma le voluma. O le mea lea, o mea maneta tumau i O le EPS e masani lava ona maualuga-fa'atinoga sintered po'o vevela-oomi maneta NdFeB.

I totonu faʻaopoopo i le faʻauluina afi o taavale malosi fou, o afi i luga o le isi vaega o le taavale o micro-motors uma. Micro-motors e maualalo mana'oga ile maneta. I le taimi nei, o le ferrite o le mea autu. Ae ui i lea, o le lelei o le faʻaaogaina o afi O le NdFeB ua fa'ateleina e 8-50%. O le faʻaaogaina o le eletise e faʻaititia i le 10% ma le ua faaitiitia le mamafa e sili atu i le 50%, lea ua avea ma tulaga atinae o micro motors i le lumanaʻi.

 

Mo faʻataʻitaʻiga, o masini eseese i luga o taavale o se vaaiga o loʻo iai maneta tumau NdFeB fa'aoga i ta'avale malosi fou. O masini e masani ona faʻaaogaina maneta tumau aofia ai: sensors mamao, sensors taofi, sensors fusipa'u nofoa, ma isi fa'aaoga masini Hall. I le Hall sensors, e faʻaaogaina maneta tumau e gaosia maneta e fa'atupu ai elemene o le Hall fa'aoso fa'afefete, fa'apea fa'atupuina le malosi eletise, fa'atasi ai ma le fa'aitiitiga ma le tu'ufa'atasia o Hall sensor atinae, o le filifiliga o maneta tumau e masani ona faaaoga NdFeB maneta tumau ma mea lelei maneta ma laʻititi laʻititi.

 

Ta'avale failauga o se isi vaaiga e faʻaoga ai maneta tumau NdFeB taavale malosi fou. O le faatinoga o maneta tumau e iai sona aafiaga tuusao i le lelei o leo o sipika. O le maualuga o le maneta flux density o maneta tumau, o le maualuga o le lagona o failauga ma sili atu le tumau. I le tulaga lautele, o le failauga E faigofie ona fai a leo, ma e le palapala le leo. O maneta tumau o failauga i luga o le maketi tele e aofia ai AlNiCo, ferrite ma NdFeB. O mea maneta o NdFeB e sili mamao atu i latou o AlNi ma ferrite. Aemaise mo tulaga maualuga failauga, o le tele o latou e faʻaaogaina le NdFeB.

 

O tatou kamupani tu'uina atu le tele o NdFeB, fusifusia NdFeB, tui molded maneta mama, ferrite maneta ta'ele, NdFeB malosi maneta ta'ele, ma isi. Matou te saunia auaunaga faʻapitoa mo tagata faʻatau, faʻamolemole lagona le saoloto e faʻafesoʻotaʻi i matou pe a e manaʻomia.
