Buntáiste:
Tá airíonna na maighnéid seo i bhfad níos fearr ná na cinn thraidisiúnta agus is iad na cinn is cumhachtaí i bhfeidhmiú faoi láthair. A n-ard
Ceadaíonn comhéigeantacht agus ard-remanence an dearadh nua agus an fhéidearthacht réimse maighnéadach iarratais a mhéadú nuair a bhíonn spás teoranta
nó i gcás ina bhfuil gá le réimse maighnéadach láidir.
Tá maighnéid NdFeB an-so-ghabhálach do chreimeadh. Dá bhrí sin a cheangal ar sciath dromchla cosanta. Tá úsáidí maighnéad NdFeB coinníollach
de réir an teocht i raon leathan ag rith ó 80ºC go 230ºC. Agus freisin oibríonn sé ag teocht faoi bhun 0 ℃.
Feidhmchlár:
Úsáidtear maighnéid neodimiam mar chineálacha éagsúla lionsaí maighnéadacha chun díriú, sraonadh cáithníní luchtaithe i leictreonaic, córais coscáin,
drip, braiteoir, córas maighnéadach i rótar agus micrea-mhótair, agus réimse na heolaíochta, na míochaine (tomagrafaíocht, speictriméadar NMR), etc.
Sa lá atá inniu ann, úsáidtear maighnéid NdFeB i gcainníochtaí móra ar fud an domhain. Níl forbairt an ábhair seo críochnaithe fós; an iarsmaí
agus tá neart páirce comhéigeantach á mhéadú go leanúnach. Ciallaíonn ardfhuinneamh maighnéid NdFeB gur féidir mótair agus braiteoirí a thógáil
níos lú riamh – agus léiríonn sé seo méadú ar éifeachtúlacht feidhmíochta. Mar gheall ar na feabhsuithe leanúnacha is féidir an t-ábhar spéisiúil seo a leanúint ar aghaidh.
a thabhairt isteach go nua i réimsí nua.
Socraíodh na luachanna sonraithe go léir ag baint úsáide as samplaí caighdeánacha de réir IEC 60404-5. Feidhmíonn na sonraíochtaí seo a leanas mar luachanna tagartha agus
d’fhéadfadh a bheith difriúil. Le haghaidh tuilleadh faisnéise déan teagmháil lenár n-innealtóirí iarratais.
