Danho 5 - Sintering

Simbi yakaumbwa inozoiswa muchoto chemagetsi icho chinopisa zvishoma nezvishoma musanganiswa wesimbi kubva pa250°C (482°F) kusvika pa900°C (1652°F).

Ko neodymium iron boron magineti anogadzirwa sei?Zvinogona kutora maawa ari pakati pe20 ne36 kuti magineti apise, zvichienderana nemhando yemagineti yekupedzisira. Iyo yemhando yepamusoro magineti inogara muovheni kwenguva yakareba kupfuura yemhando yakaderera magineti nekuti inononoka kukwira tembiricha inogadzira simba remagineti.

Nhanho 8 - Magnetization

Pakupedzisira, musanganiswa wesimbi, boron uye neodymium une magnetized. Muchina wemagnetizing unotenderedza magineti ine simba remagineti, uchipfuura 2400 volts yemagetsi emagetsi kuburikidza nemagineti kugadzira chisingaperi neodymium magineti.
