Nā māka like ʻole o Bonded NdfeB Magnet

ʻO ka wehewehe pōkole:

ʻO NdFeB i hoʻopaʻa ʻia, i haku ʻia me Nd2Fe14B, he magnet synthetic.He mea magnet ia ma o ka hui ʻana i ka pauka magnetic NdFeB i hoʻopaʻa ʻia a hoʻopaʻa ʻia ma o ka "compression molding" a i ʻole "injection molding".ʻO nā magnet NdFeB kaomi a me nā neodymium Iron boron magnet i hoʻohana pinepine ʻia i waena o lākou.

Hiʻona Huahana

Nā hiʻohiʻona magnet NdFeB i hoʻopaʻa ʻia:
1. Mākēneki waiwai ma waena o ka sintered NdFeB magnet a me ferrite magnet, he kiʻekiʻe hana isotropic mau manakia me ka maikai kūlike a me ka paʻa.
2. Hiki ke hana ʻia i mau magnet mau o nā liʻiliʻi liʻiliʻi, nā ʻano paʻakikī a me ka pololei geometric kiʻekiʻe me ka paʻi paʻi a me ka hoʻoheheʻe ʻana.Maʻalahi e hoʻokō i ka hana automate nui.
3. Hiki ke magnetized ma o kekahi kuhikuhi.Hiki ke hoʻokō ʻia nā pou he nui a i ʻole nā ​​helu he nui ma NdFeB paʻa.
4. Hoʻohana nui ʻia nā magnet NdFeB i hoʻopaʻa ʻia i nā ʻano ʻano micro motors, e like me ka mīkini spindle, synchronous motor, stepper motor, DC motor, brushless motor, etc.
