Motika synchronous magnet mau loaUa loaʻa i nā PMM (s) ka nānā nui ʻia ma nā noi like ʻole ma muli o ko lākou pono kiʻekiʻe i hoʻohālikelike ʻia me nā mea maʻamau.motika hoʻokomo asynchronous ʻekolu paes. ʻO kekahi o nā kumu nui no ka hoʻomaikaʻi ʻana i ka pono e waiho ana i nā ʻano hana kūikawā o nā PMM, ʻoi aku hoʻi ma lalo o nā kūlana hana maʻamau.
ʻO ka motika synchronous magnet mau loa he ʻekolu mau ʻāpana nui: kahi stator, kahi rotor, a me kahi hale. Ua like me ke kūlana maʻamaumīkini hoʻokomo AC ʻekolu paes, ua kūkulu ʻia ke kumu stator ma ke ʻano he ʻano laminated e hōʻemi i ka nalowale hao i hoʻokumu ʻia e ke au eddy a me nā hopena hysteresis i ka wā o ka hana motika. ʻO ka wili maʻamau he ʻano symmetrical ʻekolu-phase, ʻoiai ʻokoʻa loa ke koho ʻana o ka parameter. Loaʻa ka ʻāpana rotor i nā ʻano like ʻole, me nā rotors magnet mau loa me nā hale squirrel hoʻomaka a me nā rotors magnet mau loa i hoʻokomo ʻia a i ʻole i kau ʻia ma luna. Hiki ke hana ʻia ke kumu rotor ma ke ʻano he ʻano paʻa a i ʻole laminated. Ua lako ka rotor me ka mea magnet mau loa, i kapa pinepine ʻia ʻo ke kila magnetic.
No ka motika magnet mau loa, ua kūlike nā kahua rotor a me stator. ʻO ke ʻano o kēia hana synchronous, e wili ana ka rotor i ka wikiwiki like me ke kahua magnetic wili i hana ʻia e ka stator. ʻO ka hopena, ʻaʻohe au i hoʻokomo ʻia i loko o ka ʻāpana rotor. He mea koʻikoʻi kēia nele o ke au i hoʻokomo ʻia no ka mea e hoʻopau ana i kekahi mau ʻano o ka nalowale ikehu i loaʻa pinepine i nā ʻano motika ʻē aʻe.
Eia kekahi, ua pilikia ka mea rotor i ka hysteresis a me nā pohō o ke au eddy i kona pane ʻana i kahi kahua magnetic e loli nei. I ka hoʻohālikelike ʻana, nā motika magnet mau loa (PMMs) hōʻike i ka pohō liʻiliʻi ma muli o ka nele o ka hysteresis a me nā hopena o ke au eddy. Hana ʻia ka rotor me nā magnet mau, kahi e hana ai i kahi kahua magnetic me ka ʻole o ka pono o ke au o waho, no laila e pale aku ana i nā pohō pili a me ka hoʻomehana ʻana. Eia kekahi, ʻo ka hōʻemi ʻana i nā pohō rotor e hiki ai i nā PMM ke hana ma nā pono kiʻekiʻe, ʻoi aku ma mua o 90%. ʻO kēia pono i hoʻonui ʻia e unuhi ʻia i ka hoʻemi ʻana i ka hoʻohana ʻana i ka ikehu, nā kumukūʻai hana haʻahaʻa, a me ka emi ʻana o ka hanauna wela, hiki ke hoʻolōʻihi i ke ola o ka motika a me kāna mau ʻāpana. I ka hōʻuluʻulu manaʻo, ʻo ka hana synchronous o nā kahua rotor a me stator i loko o kahi motika magnet mau loa e hoʻopau i nā au i hoʻokomo ʻia a me nā pohō pili, e ʻoi aku ka maikaʻi ma mua o kahi motika induction. ʻAʻole wale kēia pono e hoʻomaikaʻi i ka hana, akā hāʻawi pū kekahi i ka mālama ʻana i ka ikehu a me ka hoʻomau ʻana i nā ʻano noi ʻoihana like ʻole.
