Pūkaha Commutator - he pūrere me te whakamahi o

Hei whakahoki i te pātai o te mea he motor commutator, he mea e tika ana ki te matau huaina te mea ko te pūkaha i te katoa. Tenei mīhini hiko, whakamuri generator. Heoi, ko te generator me te pūkaha i huaina ko te mīhini DC. Kei te hangaia te reira ki te tahuri pūngao pūkaha ki te pūngao hiko (arā, mahi rite he generator) ranei hurihia - hiko ki aunoa (mahi rite te pūkaha). Ki te whakatinana koe i te tukutahinga motokā DC tango, whiwhi tatou i te pūkaha commutator. I roto i te aratau generator, ka mahi i te kaikohi rite te rectifier i roto i te aratau nekeneke - te pūtahuri auau. Ngā mihi ki reira he nāianei tauutuutu rere i roto i te armature awhiowhio me te ara iahiko waho - tamau.

whai te reira i te mua e te pūkaha commutator - he mīhini hiko tukutahinga i roto i nei te tūranga pūoko rotor, me te whakawhiti o nāianei i roto i te kopiko - he kōpuku paraihe-collectron. Ko e mo'oni, rite kua whakahuatia, reira kia waiho noa te generator.

Te nekeneke commutator iti (he torutoru Watts) ngā o te wahi whakahauanga rite te rotor toru-pou ahunga, te kōpuku kohikohi (ngā reira o paraharaha parahi e rua, brushes), e rua pou stator aukume tūturu. Ko te pūrere iti rawa o te momo i whakamahia i roto i te taonga tākaro o te tahi mau tamariki.

Te nekeneke commutator he atu te mana, te tikanga he rotor maha-pou, ahunga, huihui maha ki te brushes waro wha, wha-pou stator aukume tūturu. E he motors o tenei hoahoa i roto i cars, i roto i te puku tahi, ngā pūnaha tautauā me te ventilation, papua, wipers me pera i runga i. Ko te painga matua o te pūrere pērā i commutator nekeneke, kia whakahuatia te tapatahi o te mahi, tiaki me te hanga.

pūrere kaha (e rave rahi rau Watts) ki roto i stators electromagnets. He maha ngā huarahi taketake ki te hono i taua kopiko i te raupapa ki te rotor (excitation ngā, tika taipana mōrahi, Heoi, ko te rerekē haere tere o tāhuna), faitatau ki te rotor (te painga whakanekeneke pera-ka karanga nei e taea te huaina pūmautanga o te tere, ko te mau hapehape i ki te kawe i te taipana iti mōrahi ). He hoki kōwhiringa ki te whakauru, me te motuhake oaoa, engari he ratou tika onge.

He he he mīhini taua, pera i te kaikohi AC nekeneke. Heoi, e kore e taea te whakaaro te reira motuhake. I raro i te mīhini taua matau nuitia nekeneke commutator ao. Ko te ahua o te motokā e rere i runga i nāianei hāngai, me te tauutuutu tenei. kua horahia e te taputapu taua i roto i taputapu ā-ringa, me te mana i roto i te tahi mau taputapu whare, te whakawhetai ki te rahi iti, taimaha, te utu iti, noho pai o te mahi. Ka taea te tika hono te pūkaha commutator ao pērā ki te whatunga, te mea he nāianei tīmatanga iti, he ara iahiko mana ohie.
