| Phawula: · Phantsi kobushushu bokusebenza obuyi-20℃±2℃, ngaphezulu kweeparamitha zemagnethi kunye neempawu ezibonakalayo ziyavavanywa, kunye nelahleko engenakuthintelwa yamandla kazibuthe akukho ngaphezu kwe-5%.· Ubushushu bokusebenza bemagnethi bunokutshintshwa ngenxa yobungakanani bobude kunye nedayamitha kunye nezinto ezisingqongileyo. . | ||||||||
I-advanteji:
Iipropati zezi magnethi zingaphezulu lee kunezo zemveli kwaye ngoku zezona zinamandla ekusebenziseni. Ukuphakama kwabo
ukunyanzeliswa kunye nokugcinwa okuphezulu kuvumela ukuyila okutsha kunye nokwenzeka kokwandisa indawo yamagnetic yesicelo apho indawo iyancipha
okanye apho kufuneka umhlaba owomeleleyo wemagnethi.
Iimagnethi ze-NdFeB zichaphazeleka kakhulu kukumhlwa. Ke ngoko kufuna i-coating surface ekhuselayo. Ukusetyenziswa kwemagnethi ye-NdFeB kukho imeko
ngamaqondo obushushu kuluhlu olubanzi oluqhuba ukusuka kuma-80ºC ukuya kuma-230ºC. Kwaye isebenza kwiqondo lobushushu elingaphantsi kwe-0℃.
Isicelo:
Imagnethi ye-Neodymium isetyenziswa njengeentlobo ezahlukeneyo zeelensi zemagneti zokugxila, ukuphambuka kwamasuntswana ahlawuliweyo kwi-elektroniki, iinkqubo zebrake,
i-drip, inzwa, inkqubo yamagnetic kwi-rotor kunye ne-micro motors, kunye nentsimi yesayensi, iyeza (i-tomography, i-NMR spectrometers), njl.
Namhlanje, iimagnethi zeNdFeB zisetyenziswa ngobuninzi kwihlabathi liphela. Ukuphuhliswa kwesi sixhobo akukagqibi; ukushiyeka
kwaye amandla entsimi okunyanzeliswa ayanda ngokuqhubekayo. Amandla aphezulu emagnethi e-NdFeB athetha ukuba iimotor kunye ne-sensor zinokwakhiwa
Ihlala incinci - kwaye oku kuthetha ukonyuka kokusebenza kakuhle. Uphuculo oluqhubekayo lwenza ukuba le mathiriyeli inomdla iqhubeke.
yaziswa rhoqo kwiindawo ezintsha.
Onke amaxabiso achaziweyo agqitywe kusetyenziswa iisampuli eziqhelekileyo ngokwe-IEC 60404-5. Ezi nkcukacha zilandelayo zisebenza njengemilinganiselo yereferensi kunye
inokwahluka. Ngolwazi oluthe vetshe nceda uqhagamshelane neenjineli zethu zesicelo.
