Ngā mea paraihe waro

Kei te kōrero tātou mō ngā paraihe waro mō ngā taputapu hiko i tēnei rā. Ko te paraihe waro (paraihe waro), e kiia ana hoki he paraihe, he mea pahekeheke, he mea whakamahi whānuitia i roto i te maha o ngā taputapu hiko. Ko ngā rauemi matua o te paraihe waro i roto i te tono hua ko te karāhe, te karāhe kua whakakīia, te karāhe whakarewa (kei roto he parahi, he hiriwa). He nui āu paraihe waro hei haere mā roto i te pouaka?

📍 Āhea me whakakapi te paraihe waro?
① He nui te mura, ka tahuna e te paraihe waro te mata pa o te rotor, tangohia atu, ka murua ki te pepa kirikiri. Ko te āhuatanga mura pea ko te paunga o te parahi i runga i te kaitahuri rotor, he nui te mura o te ara iahiko poto, ā, kua heke te mahi kawe hiko.
Kāore e tahuri te paraihe waro (②), kua pau.
(3) Kāore tetahi o ngā take e rua i runga ake nei, arā, ko te paraihe waro momo puna, kāore i te rawaka te pēhanga puna kotahi, ka hua ake te kore e piri te pa o te paraihe waro me te rotor ki te mura o te ara iahiko poto, me tango te waea parahi o te paraihe waro, tāpirihia kia rua ngā puna.
(4) Kei te whakamahia te pepa parahi i runga ake i te paraihe waro, kāore he tūranga kāri o te pepa parahi, ka whakakī te waea parahi i runga ake i te hurihuri o te pepa parahi, kāore e taea e te paraihe waro te tata ki te rotor, he iti te mura, me tango me te rūrū.

📍 Te mahi a te paraihe waro
Mōta paraihe He mea tito ngā mōta katoa i te stator me te rotor, i roto i te mōta DC, kia huri ake ai te rotor, me whakarerekē tonu te ahunga o te ia, ki te kore ka taea e te rotor te huri i te haurua porowhita anake, he rite ki te takahuri i te pātaka pahikara, ka taea e te waewae kotahi te takahuri i te haurua porowhita anake, nō reira me whakarerekē e te mōta DC te ia i roto i te rotor, arā, te ahunga o te kaiārahi ia me huri whakamuri. Ko te whakarerekētanga o te commutator ko te wā e tukuna ana he kaiārahi hiko ki roto i te mara hikohiko hei tapahi i te mara aukume, ka panaia te kaiārahi i waho o te mara aukume tūmau, nā te mea ka pēhia te rārangi mara aukume o te mara aukume e te mara hikohiko huri noa i te kaiārahi, ā, ka ngana te rārangi mara aukume ki te hoki ki te āhua tika, he rite ki te whakaputa i ngā kaha kukume me te pana kia huri ai te mōta. E rua ngā wāhanga haurua porowhita o te commutator e wehea ana e te rauemi ārai. Ka huri ngā wāhanga e rua hei hono atu ki te paraihe waro, ā, ka honoa tonutia te paraihe waro ki te wāhanga o te whakawhitiwhiti e tūtaki ana ki te kaha taraiwa, kia huri ai te motuka tukurua.

📍 Ngā raruraru i pā ki te whakakapi i te paraihe waro me ngā otinga
Raru: 1, he nui te pakaru o te paraihe waro
Te take:
A. Te awe o te rauemi paraihe waro. He rerekē ngā kaihanga rerekē, he rerekē ngā tauira o te hanganga o te paraihe waro, he rerekē hoki te tere o te pakaru. Nō reira, i te wā e whakakapia ana te paraihe waro, whiriwhiria te waitohu kotahi o te paraihe waro;
B. Te mutunga o te mata o te mowhiti paheke. Ka teitei ake te mutunga o te mata o te mowhiti paheke, ka iti ake te tauwehenga waku, ā, ka iti ake te tere pakaru o te paraihe waro.
C Te pānga o te pēhanga o te puna. Ka nui ake te pēhanga o te puna ka pakaru te paraihe waro; I taua wā anō, he iti rawa te pēhanga o te puna, ahakoa he iti te waku i waenga i te paraihe waro me te mowhiti paheke, engari he ngāwari te whakaputa i ngā mura ina pā kino, kāore hoki e hiahiatia;
D. Te pānga o te iahiko. I te nuinga o te wā, mō ngā paraihe waro karāhe, he nui ake te iahiko e rere ana i roto i te paraihe waro pai i te iahiko e rere ana i roto i te paraihe waro kino, nō reira he nui ake te pakaru o te paraihe waro pai i te pakaru o te paraihe waro kino, ā, he nui ake te pakaru o te mowhiti paheke pai i te mowhiti paheke kino.
Ko te otinga:
1, whakarei ake i te mahi whakahinuhinu o te paraihe waro, tae atu ki te whakahinuhinu-ā-roto me te whakahinuhinu mata o te paraihe waro, te ātete pāmahana teitei o te rauemi whakahinuhinu tāpiri;
2, whakarei ake i te pumau kounga o te paraihe waro;
3, whakarei ake i te mahi tahi o te paraihe waro me te commutator (commutator);
4, kia mau tonu te mahi a te puna.

Raru: 2, ahi paraihe waro
Te take:
A. Nā te nui rawa o te ia e rere ana i roto i te paraihe waro i puta mai;
B. Nā te kāri waro kawakore, ka pā te pahūtanga wā poto ki te mowhiti paheke.
Ko te otinga:
1, kia tupato ki te whiriwhiri i te tauira mahi e ōrite ana ki te paraihe waro;
2, whakarei ake i te whakahinuhinu-ā-roto me te whakahinuhinu mata o te paraihe waro, me te ātete pāmahana teitei o te rauemi whakaiti kakahu tāpiri.

Raru: 3, he teitei te pāmahana o te paraihe waro
Te take:
A. te taumaha rawa o te pūnaha whakaoho;
B. He iti te mata e pā ana ki te paraihe waro me te mowhiti paheke;
C. Te kounga o te paraihe waro tonu.
Ko te otinga:
1, kia tupato ki te whiriwhiri i te tauira mahi e ōrite ana ki te paraihe waro;
2, whakarei ake i te whakahinuhinu-ā-roto me te whakahinuhinu mata o te paraihe waro, me te ātete pāmahana teitei o te rauemi whakaiti kakahu tāpiri.
3. Kia tupato ki te whiriwhiri i ngā paraihe waro me te kounga pumau.

Raru: 4. Kua tino pakaru te paraihe waro
Te take:
A. Te pāmahana teitei o te paraihe waro;
B. Kāore i te pai te oro o te paraihe waro;
C. He nui te wiri o te waeine, ā, kua mau te paraihe waro ki roto i te kakau paraihe;
D. Kāore i te pai te kounga o te paraihe waro.
Ko te otinga:
1, kia tupato ki te whiriwhiri i te tauira mahi e ōrite ana ki te paraihe waro;
2, whakarei ake i te whakahinuhinu-ā-roto me te whakahinuhinu mata o te paraihe waro, me te ātete pāmahana teitei o te rauemi whakaiti kakahu tāpiri.
3, whiriwhiria he paraihe waro kounga pono me te pumau.

Raru: 5, te pekepeke o te paraihe waro
Take: Kua pakaru ngā wahi angiangi o te paraihe waro i te takanga ki roto i te kakau paraihe, i ētahi atu take rānei
Ko te otinga:
1, kia tupato ki te whiriwhiri i te tauira mahi e ōrite ana ki te paraihe waro;
2, whiriwhiria he paraihe waro kounga pono me te pumau.
3, whakarei ake i te whakahinuhinu-ā-roto me te whakahinuhinu mata o te paraihe waro, me te ātete pāmahana teitei o te rauemi whakaiti kakahu tāpiri.
