Ngā motuka mowhiti paheke, e mōhiotia ana ko ngā motuka rotor pakaru, koinei te uho o te mahangā tono tuku mana-teitei.He whānuitia te whakamahinga i roto i ngā ahumahi rauemi mata pērā i tekeri maina, ngā ahumahi rauemi mata kohuke or ngā ahumahi piripiripērā i te sima, te kōhatu, me te gypsum i roto i ngā tukanga kuru, pēhi roera, me te huri. Ka whakamahia hoki ēnei ki roto i ngā pā nui, ngā papu, me ngā kaikawe.
Te pūmau:
He rite tonu te hanganga o te stator o ngā motuka squirrel-cage me ngā motuka paheke-mowhiti. Ko te rerekētanga matua o ngā motuka whakapūmau paheke-mowhiti kei roto i te hanganga rotor me te aratau mahi. Ina whakamahia ngā motuka paheke-mowhiti i roto i ngā pūnaha cascade, ka tūpono pea ētahi huringa ki te stator nā te mea ko te pūtake hiko o te motuka i ahu mai i te mana whakahaere o te rotor o tētahi atu motuka paheke-mowhiti, kei reira ngā ātete o waho e tāutahia ana ki tana rotor.
Rotora:
He aha te mowhiti paheke? Ko te tikanga, he rotor te motuka mowhiti paheke me te stator takai-wāhanga. He takai tohatoha-rua-wāhanga-toru tēnei momo rotor, he mea tito mai i ngā koiri e whakamahia ana i roto i te whakaputa hiko AC. He mea hanga te matua rotor ki ngā whakapiri maitai, ā, he mokowā hei whakauru i ngā takai kotahi-wāhanga-toru kua hangaia. Ka wehea ēnei takai mā te hiko e te 120 nekehanga. Ahakoa ka takaihia te stator ki ngā wāhanga e rua, ko te maha o ngā takai stator e takaihia ana ki te rotor he rite tonu ki te maha i roto i te stator, ā, he toru-wāhanga tonu. Ka arahina atu ēnei takai e toru mai i tetahi pito ki roto, ā, ka honoa ki ngā mowhiti paheke e toru kua whakamahanatia ki runga i te rakau rotor. Ka pa atu ngā pito e toru ki ēnei mowhiti paheke e toru mā te awhina o ngā paraihe waro, e mau ana ki ngā mowhiti e ngā wāhanga puna. Ka honoa atu anō ēnei paraihe waro e toru ki waho ki te rheostat hononga tīmatanga-toru. Ka taea e te mowhiti paheke me te rheostat o waho te whakanui ake i te ātete o waho o te ara iahiko rotor, ka nui ake te ātete i te wā tīmatanga, ā, ka whakanui ake i te taipana tīmatanga. I raro i ngā āhuatanga mahi noa, ka whakaoti aunoa te mowhiti paheke i te ara iahiko mā roto i te mowhiti ringaringa whakarewa. Ka panaia te mowhiti ringaringa whakarewa i te taha o te pou, ka pā ngā mowhiti e toru tetahi ki tetahi. Hei tāpiri, ka ara aunoa ngā paraihe mai i te mowhiti paheke hei karo i te ngaronga o te waku me te pakaru. I raro i ngā āhuatanga mahi noa, he rite tonu te mahi a te hurihanga mowhiti paheke ki tā te hurihanga whare-ngārara.
He aha te mea ka puta mēnā ka tāpirihia he ātete o waho? Mō ngā motuka whakapūmau he whare-ngāwari, he tino iti te ātete o te rotor, nō reira he tino teitei te ia o te rotor, ka kino ake te taipana tīmatanga. Heoi, mēnā ka tāpirihia he ātete o waho mō ngā motuka mowhiti-paheke, ka piki ake te ātete o te rotor i te tīmatanga, nō reira he iti te ia o te rotor, ā, ko te taipana tīmatanga te mōrahi. Heoi anō, ko te paheke e hiahiatia ana hei whakaputa i te taipana mōrahi he rite ki te ātete o te rotor. I roto i ngā motuka mowhiti-paheke, mā te whakanui ake i te ātete o waho hei whakanui ake i te ātete o te rotor, ka piki ake te paheke. Nā te ātete o te rotor teitei, he nui ake te paheke, nō reira ahakoa i ngā tere iti, ka taea te whakatutuki i te taipana "tōia". Ina tae te motuka ki tōna tere taketake (tere whakatauranga katoa), ina tangohia te ātete o waho, ā, i raro i ngā tikanga whakahaere noa, ko tōna aratau whakahaere he rite tonu ki te aratau o ngā motuka whakapūmau he whare-ngāwari. Nō reira, he tino pai ēnei motuka mō ngā kawenga tino teitei, e kore nei e hiahiatia he taipana tōia i ngā tere iti me te whakaterenga ki te tere katoa, ā, ka mimiti i te ia iti rawa i roto i te wā poto rawa.
Ngā painga o ngā motuka whakapūmau mowhiti-paheke:
Ko te painga matua o ngā motuka arataki mowhiti-paheke he mea ka taea e rātou tekia ngāwari te whakahaere i te tere.Ahakoa te tere kore, ka taea tonu te whakatutuki i te "taipana tōia". Ki te whakatauritea ki ngā motuka hiko-whare-pūngoi, he nui ake te taipana tīmatanga. Ko te taipana kawenga-katoa he tata ki te 200-250% o te taipana kawenga-katoa. Ko ngā motuka hiko-whare-pūngoi te 600-700% o te iahiko kawenga-katoa, engari he tino iti te iahiko tīmatanga o ngā motuka hiko-mīti paheke, tata ki te 250-350% o te iahiko kawenga-katoa.
