Buannachd:
Tha feartan nan magnets sin fada nas fheàrr na feadhainn traidiseanta agus is iad an-dràsta an fheadhainn as cumhachdaiche ann an cleachdadh. An àrd aca
tha co-èigneachadh agus fuigheall àrd a’ ceadachadh an dealbhadh ùr agus an comas raon tagraidh magnetach a mheudachadh far a bheil àite cuibhrichte
no far a bheil feum air raon magnetach làidir.
Tha magnets NdFeB gu math buailteach do chreachadh. Mar sin feumar còmhdach uachdar dìon. Tha cleachdadh magnet NdFeB air a shuidheachadh
leis an teòthachd ann an raon farsaing a 'ruith bho 80ºC gu 230ºC. Agus cuideachd tha e ag obair aig teòthachd fo 0 ℃.
Iarrtas:
Bithear a ’cleachdadh magnets neodymium mar dhiofar sheòrsaichean de lionsan magnetach airson fòcas, sleamhnachadh gràinean fo chasaid ann an electronics, siostaman breic,
drip, sensor, siostam magnetach ann an rotor agus meanbh-motaran, agus raon saidheans, cungaidh-leigheis (tomography, speactrometers NMR), msaa.
An-diugh, thathas a’ cleachdadh magnets NdFeB ann am meudan mòra air feadh an t-saoghail. Chan eil leasachadh an stuth seo deiseil fhathast; am fuigheall
agus tha neart achaidh co-èigneachail air a mheudachadh gu cunbhalach. Tha lùth àrd magnets NdFeB a’ ciallachadh gun gabh motaran agus mothachairean a thogail
nas lugha a-riamh - agus tha seo a’ comharrachadh àrdachadh ann an èifeachdas coileanaidh. Tha na leasachaidhean leantainneach a’ toirt cothrom don stuth inntinneach seo a bhith air a leantainn
air a thoirt a-steach gu raointean ùra.
Chaidh na luachan ainmichte uile a dhearbhadh a’ cleachdadh sampallan àbhaisteach a rèir IEC 60404-5. Tha na sònrachaidhean a leanas mar luachan iomraidh agus
faodaidh eadar-dhealaichte. Airson tuilleadh fiosrachaidh cuir fios chun na h-innleadairean tagraidh againn.
