| Kumbuka: · Tunasalia kama ilivyo hapo juu isipokuwa tu kama tumebainishwa na mteja. Mgawo wa halijoto ya Curie na halijoto ni kwa ajili ya marejeleo pekee, si kama msingi wa uamuzi.· Kiwango cha juu cha halijoto cha kufanya kazi cha sumaku kinaweza kubadilika kutokana na uwiano wa urefu na kipenyo na vipengele vya mazingira. | |||||||||
Faida:
Utumiaji wa sumaku hizi huchangiwa na halijoto katika anuwai ya kuanzia 250ºC hadi 350ºC na halijoto yao ya Curie inaweza kuwa juu zaidi.
kama 710 hadi 880 °C. Kwa hiyo, sumaku ya SmCo ina utulivu bora wa magnetic kutokana na upinzani wa juu kwa joto la juu.
Sumaku za SmCo zina sifa ya upinzani wa juu sana wa kutu, hakuna mipako inayohitajika kwa ulinzi wa uso.
Kipengele:
Ubaya wa sumaku za SmCo ni ugumu wa nyenzo - jambo ambalo lazima izingatiwe wakati wa usindikaji.
Sumaku ni mabati au coated na electrodeposition cathodic kwa ajili ya maombi fulani.
Maombi:
Katika maeneo ya joto la juu la uendeshaji, kutu ya juu na upinzani wa oxidation ni muhimu. Kama vile, magnetron ya kielektroniki,Sumakumaambukizi ya ic,
Matibabu ya sumaku, Magnistor, nk.
Thamani zote zilizotajwa ziliamuliwa kwa kutumia sampuli za kawaida kulingana na IEC 60404-5. Vibainishi vifuatavyo vinatumika kama maadili ya marejeleo na yanaweza
tofauti. Upeo wa juu. hali ya joto ya uendeshaji inategemea dimesion sumaku na maombi maalum. Kwa habari zaidi tafadhali wasiliana nasi
