He aha nā mea magnet mau? ʻO nā mākēneki honua, nā mākēneki ikaika i hana ʻia mai nā metala honua laha ʻole, ʻo ia ke ʻano maʻamau no kēia kumu. ʻAʻole ʻokoʻa loa nā mākēneki honua; ua hele mai lākou mai ka papa o nā metala i ʻike ʻia he metala honua laha ʻole. Aia kekahi mau metala ʻē aʻe e lilo wale i ka magnetic ke hoʻomākeʻe ʻia e kahi māla uila a noho wale i ka magnet i ka wā e paʻa ana kēlā kahua uila.
Aia kēia manaʻo ma ka puʻuwai o ka hana ʻana o nā kaʻa PM. Ma nā kaʻa PM, hoʻohana ʻia kahi wili uila ma ke ʻano he electromagnet ke hele ka uila ma ia. Hoʻokomo ʻia ka coil electromagnetic i ka magnet mau loa, a ʻo kēia mea hoihoi ke kumu e hoʻohuli ai ka moto. Ke hoʻoneʻe ʻia ke kumu o ka mana uila, nalowale ka uea i kona mau ʻano magnetic a kū ke kaʻa. Ma kēia ala, hiki ke hoʻokele ʻia ka hoʻololi ʻana a me ka neʻe ʻana o nā kaʻa PM e ka mea hoʻokele kaʻa e hoʻokele i ka wā a pehea ka lōʻihi o ka uila a, ma ka hoʻonui ʻana, ka electromagnet, hiki ke hoʻololi i ka kaʻa.
Hōʻike ʻia nā kiʻi ma luna aʻe i kahi kaʻa magnet paʻa, a i ʻole "PM". Loaʻa i ka rotor kahi magnet mau, e hāʻawi ana i nā kaʻa PM i ko lākou inoa. ʻO nā rotor PM he radially magnetized, ʻākau a me nā pole hema e hoʻololi ana ma ke anapuni o ka rotor. ʻO ka pitch pole ka huina ma waena o nā pou ʻelua o ka polarity hoʻokahi, ʻākau a ʻākau a i ʻole hema i ka hema. He maʻalahi ka rotor a me nā hui stator o nā kaʻa PM.
Hoʻohana nui ʻia nā mīkini PM i nā mea paʻi, kope, a me nā scanners. Hoʻohana ʻia lākou e hana i nā kīwaha i ka wai o ka hale a me nā ʻōnaehana gas a me nā mea hoʻokele kaʻa i nā noi automotive.
Pono nā magnet mau no kāu mau kaʻa? E ʻoluʻolu e kelepona mai iā mākou no ke kauoha.
