Mōta tukutahi aukume tuturuKua rongonui ngā PMM i roto i ngā momo tono nā te mea he pai ake te whai huatanga ki te whakataurite ki ngā tikanga tuku iho.motuka whakapūmau ā-wāhanga torus. Ko tētahi o ngā āhuatanga matua mō te whakapai ake i te whai huatanga ko ngā āhuatanga whakahaere ahurei o ngā PMM, inā koa i raro i ngā āhuatanga whakahaere noa.
E toru ngā wāhanga matua o te mōta tukutahi aukume tuturu: he stator, he rotor, me he whare. He rite ki te paerewamotuka hiko AC toru-wāhangas, ka hangaia te matua stator hei hanganga whakakikorua hei whakaiti i te ngaronga rino i puta mai i te au hurihuri me ngā pānga hysteresis i te wā e whakahaerehia ana te motuka. Ko te takai he hanganga ōrite-toru-wāhanga, ahakoa he rerekē te kōwhiringa tawhā. Kei te wātea te wāhanga rotor i roto i ngā momo āhua, tae atu ki ngā rotor aukume tuturu me ngā whare tīwharawhara tīmatanga me ngā rotor aukume tuturu parakore kua whakauruhia, kua whakairihia rānei ki te mata. Ka taea te hanga i te matua rotor hei hanganga totoka, hei hanganga whakakikorua rānei. Kua rite te rotor ki te rauemi aukume tuturu, e kiia ana ko te maitai aukume.
Mō te motuka aukume tuturu, kei te tukutahi ngā mara rotor me te stator. Ko te tikanga o tēnei mahi tukutahi ka huri te rotor i te tere kotahi me te mara aukume hurihuri e whakaputaina ana e te stator. Nō reira, kāore he iahiko whakaoho i roto i te wāhanga rotor. He mea nui tēnei ngaronga o te iahiko whakaoho nā te mea ka whakakorea he maha ngā momo ngaronga pūngao e kitea ana i roto i ētahi atu momo motuka.
Hei tāpiritanga, ka pāngia te rauemi rotor e te hysteresis me ngā ngaronga o te au hurihuri i a ia e aro ana ki te hurihanga o te papa aukume. He rerekē, ko ngā motuka aukume tuturu (PMMs) he iti noa te mate nā te korenga o te hysteresis me ngā pānga o te au hurihuri. He aukume tuturu te rotor, e whakaputa ana i tētahi papa aukume me te kore e hiahiatia he au o waho, ā, ka karohia ngā mate me te whakamahana e pā ana. Hei tāpiri, mā te whakaiti i ngā mate o te rotor ka taea e ngā PMM te mahi i ngā mahi tino pai, neke atu i te 90%. Ka puta mai i tēnei mahi pai ake te whakaiti i te whakapaunga pūngao, te whakaiti i ngā utu whakahaere, me te whakaiti i te whakaputanga wera, ka taea te whakaroa i te roa o te ora o te motuka me ōna wāhanga. Hei whakarāpopototanga, mā te mahi tukutahi o ngā papa rotor me te stator i roto i tētahi motuka aukume tuturu ka whakakore i ngā au whakaoho me ngā mate e pā ana, ka nui ake te pai o tēnei mahi i tētahi motuka whakaoho. Ehara i te mea ka whakapai ake tēnei mahi i te mahi anake, engari ka whai wāhi hoki ki te tiaki pūngao me te pumau i roto i ngā momo tono ahumahi.
