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 magnetized i ka wā e paʻa ai 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.Hoʻopili ʻia ka coil electromagnetic i ka magnet mau loa, a ʻo kēia mea hoihoi ke kumu e hoʻohuli ai ke kaʻa.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 manawa a pehea ka lōʻihi o ka uila a, ma ka hoʻonui ʻana, ka electromagnet, e ʻae ai i ka hoʻololi ʻana o ke kaʻa.
Hōʻike ʻia nā kiʻi ma luna aʻe i kahi kaʻa magnet paʻa, a i ʻole "PM".Loaʻa i ka rotor kahi magnet mau loa, 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.ʻO ka rotor a me nā hui stator o nā kaʻa PM he maʻalahi.
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.
