Amagqabantshintshi e-Sintered NdFeB zezona magnets zinamandla zorhwebo ezisisigxina ezikhoyo namhlanje, ezinemveliso yamandla ephezulu esukela kwi-26 MGOe ukuya kwi-52 MGOe. U-Nd-Fe-B sisizukulwana sesithathu semagneti engapheliyo ephuhliswe ngo-1980s. Inokudityaniswa okuphezulu kakhulu kokukhumbula kunye nokuqina, kwaye iza noluhlu olunamabanga, ubukhulu kunye neemilo. Ngeempawu zayo ezibalaseleyo zemagneti, ubuninzi bemveliso eluhlaza, namaxabiso aphantsi, i-Nd-Fe-B ibonelela ngokuguquguquka ngakumbi ekuyileni izinto ezintsha okanye endaweni yezinto zombane zemveli ezifana ne-ceramic, Alnico kunye neSm-Co ukufezekisa ukusebenza okuphezulu, iindleko eziphantsi kunye nokunye. izixhobo zecompact.
Izibonelelo zeMagnet ekhethiweyo
* Ukuqalwa okumandla kwabahlali base-Br.
* Ukuthintela amandla okumelana nedagnetization.
* Ixabiso elifanelekileyo elinxulumene nezixhobo zalo zemagnethi ephezulu.
