Ko te kaupapa o te whakahaere aunoa i ngā miihini whakaputa waka
Ko te kaupapa whakahaere aunoa o ngā miihini whakaputa hiko ka tutuki i te pumau o te ngaohiko mā te whakaawe hikohiko me te whakahaere i te au o te papa aukume. Koinei te tikanga motuhake:
Tikanga whakahaere i te arataki hikohiko
Ka whakarerekē aunoa te mīhini whakaputa hiko i tana whakaputa hiko kia rite ki te hiahia hiko. Ina kore e ranea te mana o te pākahiko, ina whakamahia rānei ngā taputapu hiko kaha-teitei, ka whakanuia e te mīhini whakaputa hiko te whakaputa hiko mā te whakanui ake i te au o te papa aukume. Ina kī tonu te pākahiko, ka whakaitihia aunoa te au o te papa aukume, ā, ka mau tonu te hiahia hiko taketake.
Te mātāpono o te whakahaere ngaohiko
Ka whakarerekētia te rerenga aukume mā te whakarerekē aunoa i te ia o te papa aukume kia mau tonu ai te pumau o te ngaohiko putanga. Ina huri te tere hurihuri o te whakaputa hiko, ka puta he rerekētanga o te ngaohiko, ka kitea e te kaiwhakahaere he tohu rerekē, ā, ka whakarerekētia te kaha o te papa aukume mā te whakarerekē i te ia whakaoho, kia whakahokia ai te ngaohiko ki te awhe kua whakaritea. Hei tauira, ina piki te tere hurihuri, whakaitihia te ia whakaoho hei ārai i te ngaohiko nui rawa atu; ina heke te tere hurihuri, whakanuia te ia whakaoho hei pupuri i te pumau o te ngaohiko.
Ngā momo kaiwhakahaere rerekē
Kaiwhakahaere tānga Youdaoplaceholder0 : Mā te whakahaere i te whakakā me te whakaweto o ngā hoapā tānga hei whakahaere i te ara iahiko aukume, ka tutuki te whakahaere aunoa i te ngaohiko.
Youdaoplaceholder0 Ngā kaiwhakahaere hiko (pēnei i te momo whenua ā-roto/momo whenua ā-waho): Ka whakamahia e rātou ngā wāhanga pēnei i ngā transistors me ngā diode whakau hiko hei whakahaere i te au o te aukume i roto i te ara iahiko whakakā-whakaweto.
Ka taea e tēnei pūnaha te whakataurite i te whakaputa hiko me te hiahia hiko, te karo i te moumou pūngao me te whakaroa i te roa o te ora o ngā taputapu.
Ko te pūkaha hiko o te motuka te pūtake hiko matua o te waka. Ko tana mahi he tuku hiko ki ngā taputapu hiko katoa (haunga te tīmatanga) i te wā e oma ana te miihini, ā, i te wā kotahi ka whakakī i te pākahiko.
I runga i te takai pūmau toru-wāhanga o te pūwhakawhiti hiko noa, ka whakanuia te maha o ngā hurihanga o te takai, ka arahina atu ngā pito hononga, ā, ka tāpirihia he huinga whakatikatika piriti toru-wāhanga. I ngā tere iti, ka tukuna raupapatia te takai taketake me te takai tāpiri, i ngā tere teitei ake, ko te takai toru-wāhanga taketake anake ka tukuna.
Ko te kaupapa mahi o te alternator whānui
Ina whakakahangia te takai whakaoho e te ara iahiko o waho mā te paraihe, ka puta he papa aukume, ka aukumetia ngā pou maikuku hei pou N me ngā pou S. Ina huri te rotor, ka huri te rerenga aukume i roto i ngā takai stator. E ai ki te mātāpono o te whakapūngao hikohiko, ka puta he kaha hikohiko tauutuutu i roto i ngā takai toru-wāhanga o te stator. Koinei te mātāpono whakaputa hiko o te alternator.
Ka peia te rotor o tētahi pūkaha hiko tukutahi whakaoho DC e te miihini matua (arā, te miihini) kia huri i te tere o te n(rpm), ā, ka puta he pūmanawa au hurihuri mai i te takai stator toru-wāhanga. Mena ka honoa te takai stator ki tētahi kawenga hiko, ka tukuna e te motuka he au hurihuri. Ka hurihia te au hurihuri hei au tika mā te piriti whakatikatika i roto i te pūkaha, kātahi ka tukuna mai i te pito putanga.
E rua ngā wāhanga o te pūwhakawhiti: te takai pūmau me te takai rotor. Ka tohatohahia ngā takai pūmau toru-wāhanga ki runga i te anga i te koki hiko o te 120 nekehanga ki a rātou anō, ā, e rua ngā maikuku pou o te takai rotor. Ina honoa te takai rotor ki te iahiko tika, ka whakaohokia, ā, ka hangaia e ngā pou e rua te pou N me te pou S. Ka tīmata ngā rārangi aukume mai i te pou N, ka haere mā roto i te āputa hau ki roto i te matua o te pūwhakawhiti, kātahi ka hoki ki te pou S e tata ana. Kia huri te rotor, ka tapahia e te takai rotor ngā rārangi aukume, ka puta he kaha hiko sinusoidal i roto i te takai pūmau e rerekē ana i te 120 nekehanga o te iahiko, arā, te iahiko whakawhiti toru-wāhanga, ka hurihia hei putanga iahiko tika e te huānga whakatikatika i hangaia mai i ngā diode.
Ina kati te pana, ka tukuna tuatahitia te iahiko e te pākahiko. Ko te ara iahiko ko:
Pūtake pai o te pākahiko → rama tohu utu → whakapā kaiwhakahaere → takai whakaoho → whenua → pūtake kino o te pākahiko. I tēnei wā, ka kā te rama tohu utu nā te mea he iahiko e rere ana i roto.
Heoi, i muri i te tīmatanga o te mīhini, i te pikinga o te tere hurihuri o te pūkaha hiko, ka piki tonu te ngaohiko pito o te pūkaha hiko. Ina ōrite te ngaohiko putanga o te pūkaha hiko ki te pākahiko, ka rite tonu te pūmanawa i ngā pito "B" me "D" o te pūkaha hiko. I tēnei wā, ka mate te rama tohu utu nā te korenga o te rerekētanga pūmanawa i waenga i ngā pito e rua. E tohu ana tēnei kei te mahi noa te pūkaha hiko, ā, ko te pūkaha hiko tonu te pūtake o te ia whakaoho. Ko te kaha hiko whakawhiti-wāhanga-toru e hangaia ana e te takai-wāhanga-toru i roto i te pūkaha hiko ka whakatikatikaina e te diode, kātahi ka tukuna te ia tika hei tuku hiko ki te kawenga me te utu i te pākahiko.
