Te kaupapa mahi a te motuka paraihe
Ko te hanganga matua omōta kore paraihehe stator + rotor + paraihe, ā, ka whiwhihia te taipana mā te hurihuri i te papa aukume hei whakaputa i te pūngao nekeneke. Kei te pā tonu te paraihe ki te commutator hei kawe hiko me te huri i te āhua o te hurihanga.
Ka whakamahia e te mōtini paraihe te whakawhiti ā-mīhini, kāore te pou aukume e neke, ka huri te koiri. Ina mahi te mōtini, ka huri te koiri me te whakawhiti, engari kāore te maitai aukume me te paraihe waro e huri. Ko te huringa tauutuutu o te ahunga iahiko koiri ka tutuki mā te whakawhiti me te paraihe e huri tahi ana me te mōtini.
I roto i te motuka paraihe, ko tēnei tukanga he whakarōpū i ngā pito whakauru mana e rua o te koiri, ka whakaritea kia rite ki te mowhiti, ka wehea tetahi ki tetahi me ngā rauemi whakamahana, ka hanga he rango rite ki te rango, ka huri hei mea katoa waro me te rakau motuka, ka tukuna te mana mā roto i ngā pou iti e rua i hangaia ki te waro (paraihe waro), i raro i te mahi a te pēhanga puna, mai i ngā tūranga pumau e rua, ka pēhia te whakauru mana, e rua ngā pito o te koiri porowhita porowhita ki te koiri o te huinga hiko.
I te mea ko temōtaKa huri, ka whakakahangia ngā koiri rerekē, ngā pou rerekē rānei o te koiri kotahi i ngā wā rerekē, kia rerekē ai te koki i waenganui i te pou ns o te papa aukume e whakaputa ana i te koiri me te pou ns o te stator aukume tuturu tata. Ka kukume ngā papa aukume tetahi ki tetahi, ka pana tetahi ki tetahi, ka whakaputa i te kaha me te pana i te motuka kia huri. Ka paheke te hiko waro i runga i te pane waea pērā i te paraihe i runga i te mata o tētahi mea, nō reira te ingoa "paraihe".
Mā te paheke tetahi ki tetahi ka puta te waku me te ngaronga o ngā paraihe waro, me whakakapi i ia wā. Mā te hurihanga me te whakakorenga i waenga i te paraihe waro me te pane waea o te koiri ka puta he mura hiko, he motu te hikohiko, ā, ka whakararuraru i ngā taputapu hiko.
Te kaupapa mahi a te motuka kore paraihe
I roto i te mōta kore paraihe, ka mahia te whakawhiti e te ara iahiko whakahaere i roto i te kaiwhakahaere (ko te tikanga he pūoko hōro + kaiwhakahaere, ā, ko te hangarau matatau ake ko te encoder aukume).
Ka whakamahia e te mōtini kore paraihe te whakawhitiwhiti hiko, kāore te koiri e neke, ka huri te pou aukume. Ka whakamahia e te mōtini kore paraihe he huinga taputapu hiko hei rongo i te tūranga o te pou aukume o te aukume tuturu mā roto i te huānga whare SS2712. E ai ki tēnei tikanga, ka whakamahia he ara iahiko hiko hei huri i te ahunga o te iahiko i roto i te koiri i te wā tika kia pai ai te whakaputanga o te kaha aukume ki te ahunga tika hei taraiwa i te mōtini. Whakakorehia ngā ngoikoretanga o te mōtini paraihe.
Ka kiia ēnei ara iahiko he kaiwhakahaere motuka. Ka taea hoki e te kaiwhakahaere o te motuka kore paraihe te whakatutuki i ētahi mahi kāore e taea e te motuka kore paraihe, pērā i te whakarerekē i te koki whakawhiti hiko, te aukati i te motuka, te whakamuri i te motuka, te raka i te motuka, me te whakamahi i te tohu aukati hei whakamutu i te tuku hiko ki te motuka. Inaianei, ka raka te whakaoho hiko motuka pākahiko, ka whakamahia katoatia ēnei mahi.
He hua miihini noa te mōta dc kore paraihe, he mea tito mai i te tinana mōta me te taraiwa. Nā te mea ka whakahaerehia te mōta dc kore paraihe i roto i te aratau whakahaere aunoa, kāore e tāpirihia he takai tīmatanga ki te rotor pērā i te mōta tukutahi me te whakahaere tere auau rerekē me te tīmatanga kawenga taumaha, ā, kāore e puta he wiri me te hikoi atu ina huri te kawenga.
Te rerekētanga o te aratau whakahaere tere i waenga i te motuka paraihe me te motuka kore paraihe
Ko te tikanga, ko te whakahaere i ngā momo motuka e rua ko te whakahaere i te ngaohiko, engari nā te mea he mea whakamahi te miihini kore-paraihe i te whakawhitiwhiti hiko, ka taea te whakatutuki mā te whakahaere mamati, ā, mā te miihini kore-paraihe ka whakamahia te whakawhitiwhiti waro, ka taea te whakahaere i te ara iahiko anaro tuku iho e whakahaerehia ana e te silicon, he tino māmā noa iho.
1. Ko te tukanga whakahaere tere o te motuka paraihe he whakarite i te ngaohiko o te pūtake hiko o te motuka. Whai muri i te whakarite, ka hurihia te ngaohiko me te iahiko e te commutator me te paraihe hei whakarerekē i te kaha o te papa aukume i hangaia e te irahiko kia tutuki ai te kaupapa o te whakarerekē i te tere. E mōhiotia ana tēnei tukanga ko te whakahaere pēhanga.
2. Ko te tukanga whakahaere tere o te motuka kore paraihe ko te pupuri tonu i te ngaohiko o te pūtake hiko o te motuka, ka hurihia te tohu whakahaere o te whakatikatika hiko, ka hurihia te tere whakawhiti o te ngongo MOS mana-tiketike e te tukatuka iti hei whakatutuki i te huringa o te tere. Ka kiia tēnei tukanga ko te huringa auau.
Te rerekētanga o te mahi
1. He hanganga māmā te motuka paraihe, he roa te wā whakawhanake me te hangarau pakari
I te rautau 19, i te whānautanga o te mōtini, ko te momo mōtini mahi ko te momo kore paraihe, arā, ko te mōtini kore tukutahi-whare-ā-pūwero-ā-pūwero, i whakamahia whānuitia i muri i te whakaputanga o te iahiko hurihuri. Heoi, he maha ngā hapa o te mōtini kore tukutahi-ā-pūwero, nō reira he puhoi te whanaketanga o te hangarau mōtini. Ina koa, kāore i taea te whakamahi i te mōtini kore paraihe ā-pūwero hei mahi arumoni. Nā te tere o te whanaketanga o te hangarau hiko, kua puhoi te whakamahi i te mōtini arumoni tae noa ki ngā tau tata nei. Ko te tikanga, kei roto tonu i te kāwai o te mōtini ā-pūwero.
I whānau mai te mōtini kore paraihe i ngā rā tata nei, ā, i hangaia e te tangata te mōtini dc kore paraihe. Nā te mea he māmā te tikanga o te mōtini paraihe dc, he ngāwari ki te hanga me te tukatuka, he ngāwari ki te tiaki, he ngāwari ki te whakahaere; he tere hoki te urupare a te mōtini dc, he nui te taipana tīmatanga, ā, ka taea te whakarato i te mahi taipana whakatauranga mai i te kore tere ki te tere whakatauranga, nō reira kua whānuitia te whakamahinga ina puta mai.
2. He tere te urupare a te motuka dc kore paraihe, ā, he nui te taipana tīmatanga
He tere te urupare tīmatanga o te motuka kore paraihe DC, he nui te taipana tīmatanga, he pumau te huringa tere, tata kore e rangona he wiri mai i te kore ki te tere mōrahi, ā, ka taea te akiaki i te kawenga nui ake i te wā e tīmata ana. He nui te ātete tīmatanga (tauhohenga inductive) o te motuka kore paraihe, nō reira he iti te tauwehenga mana, he iti te taipana tīmatanga, he haruru te tangi tīmatanga, he wiri kaha te haere tahi me, ā, he iti te kawenga taraiwa i te wā e tīmata ana.
3. He maeneene te oma o te motuka dc kore paraihe, ā, he pai te pānga aukati
Ka whakahaeretia te mōtini kore paraihe e te whakahaere ngaohiko, nō reira he pumau te tīmatanga me te aukati, ā, he pumau hoki te mahi tere pumau. Ko te mōtini kore paraihe ka whakahaeretia mā te hurihanga auau mamati, ka huri tuatahi i te ac ki te dc, kātahi ka dc ki te ac, ā, ka whakahaere i te tere mā te huringa auau. Nō reira, kāore te mōtini kore paraihe e oma pai i te tīmatanga me te aukati, me te wiri nui, ā, ka pumau anake ina pumau te tere.
4, he tino tika te whakahaere o te motuka paraihe dc
Ko te motuka kore paraihe DC te tikanga e whakamahia tahitia ana me te pouaka whakaiti me te wetewaehere hei whakanui ake i te mana putanga o te motuka, hei whakanui ake hoki i te tika o te whakahaere. Ka taea e te tika o te whakahaere te eke ki te 0.01 mm, ā, tata tonu ka taea te tuku i ngā wāhanga neke kia mutu ki tētahi wāhi e hiahiatia ana. Ko ngā taputapu mīhini tika katoa he motuka DC te tika o te whakahaere. Nā te mea kāore te motuka kore paraihe e pumau i te wā e tīmata ana me te aukati, ka mutu ngā wāhanga neke i ngā tūranga rerekē i ia wā, ā, ka taea anake te whakamutu i te tūranga e hiahiatia ana mā te pine tūnga, te here tūnga rānei.
5, he iti te utu whakamahi mō te motuka paraihe dc, he ngawari te tiaki
Nā te ngāwari o te hanganga o te motuka kore paraihe, te iti o te utu whakaputa, he maha ngā kaihanga kua pakari te hangarau, nō reira he whānui te whakamahinga, pērā i ngā wheketere, ngā taputapu mīhini tukatuka, ngā taputapu tika, me ētahi atu. Ki te kore e pai te motuka, me whakakapi noa te paraihe waro, he iti noa te utu mō ia paraihe waro, he tino iti te utu. Kāore anō kia pakari te hangarau motuka kore paraihe, he teitei ake te utu, he iti te whānuitanga o te tono, me whakamahi i ngā taputapu tere pumau, pērā i te hauhautanga huringa auau, te pouaka whakamātao, me ētahi atu. Ko te kino o te motuka kore paraihe ka taea anake te whakakapi.
6, kāore he paraihe, he iti te pokanoa
Ka tangohia te paraihe e ngā motuka kore paraihe, ko te rerekētanga tino tika ko te korenga o te mura o te motuka paraihe, ā, ka tino whakaitihia te pokanoa o te mura hiko ki ngā taputapu reo irirangi mamao.
7. He iti te haruru me te mahi maeneene
Ki te kore he paraihe, ka iti ake te waku o te mōtini kore paraihe i te wā e whakamahia ana, he maeneene te mahi, ā, he iti ake te haruru, he tautoko nui tēnei mō te pumau o te whakahaere o te tauira.
8. He roa te ora ratonga me te iti o te utu tiaki
Ko te nuinga o te wā ka pakaru te motuka kore paraihe, ka pakaru te motuka kore paraihe i te peera, mai i te tirohanga miihini, he motuka kore tiaki te motuka kore paraihe, me mahi noa te tiaki puehu ina hiahiatia.
