Ko te mana whakahaere puku motuka he whakahaere i te hurihanga, te aukati rānei o te motuka, me te tere o te hurihanga. Ka kiia hoki te wāhanga whakahaere puku motuka he kaiwhakahaere tere hiko (ESC). He whakatikatika hiko e rite ana ki te whakamahinga o ngā motuka rerekē, tae atu ki te whakatikatika hiko kore-paraihe me te paraihe.
Ka mau te aukume tuturu o te motuka paraihe, ka takai te koiri ki te rotor, ā, ka whakarerekētia te ahunga o te papa aukume mā te pā motumotu i waenga i te paraihe me te commutator kia mau tonu ai te hurihuri.
Mōta kore paraihe, e ai ki tōna ingoa, kāore i a ia te mea e kiia nei ko te paraihe me te kaitahuri. He aukume tuturu tōna rotor, ko te koiri ia he mea pumau. He hononga tika ki te pūtake hiko o waho.
Ina hoki, me whai mana hiko anō hoki te mōtini kore paraihe, he momo puku mōtini tēnei. Ka whakarerekētia e ia te ahunga o te iahiko i roto i te koiri pumau i ngā wā katoa, kia pai ai te pana o te kaha i waenganui i a ia me te aukume pumau, ā, kia taea ai te haere tonu o te hurihanga tonu.
Ka taea e te mōta kore paraihe te mahi me te kore e hiahiatia he whakarerekētanga hiko, ka taea te tuku hiko tika ki te mōta, engari kāore e taea te whakahaere i te tere o te mōta. Me whai whakarerekētanga hiko te mōta kore paraihe, ki te kore e kore e taea te huri. Me huri te iahiko tika ki te iahiko whakawhiti-wāhanga-toru mā te whakahaere i te iahiko kore paraihe.
Kāore te whakarerekētanga hiko tōmua i rite ki te whakarerekētanga hiko o nāianei, ko te tōmua he whakarerekētanga hiko paraihe. Mēnā ka pātai atu koe, he aha te whakarerekētanga hiko paraihe, ā, he aha te rerekētanga o te whakarerekētanga hiko kore paraihe?
Ina hoki, he rerekētanga nui i waenga i te paraihe kore me te paraihe kore, e hangai ana ki te motuka. Inaianei ko te rotor o te motuka, koinei te wāhanga ka taea te huri, he poraka aukume katoa, ā, ko te koiri te stator kāore e huri, nā te mea kāore he paraihe waro i waenganui, koinei te motuka paraihe kore.
Ā, ko te mōtini paraihe, e ai ki te ingoa, he paraihe waro, nō reira he mōtini paraihe anō hoki, pērā i te nuinga o te wā ka takaro ngā tamariki me te mana mamao o te mōtini, he mōtini paraihe.
E ai ki ngā momo mīhini hiko e rua me te ingoa o te paraihe me te paraihe - te whakahaere hiko kore utu. Mai i te tirohanga ngaio, ko te paraihe te putanga o te iahiko tika, ko te putanga mana kore paraihe he ac toru-wāhanga.
Ko te au hiko tika te hiko e rongoa ana i roto i tā tātou pākahiko, ka taea te wehewehe ki ngā pou pai me ngā pou kino. Ko te pūtake hiko o tō tātou whare 220V, e whakamahia ana mō te rihi waea pūkoro, rorohiko rānei, he AC. Ko te AC me tētahi auau motuhake, ko te tikanga he rārangi tāpiri me te tango, tāpiri me te tango whakawhiti whakamua me te whakamua; Ko te au hiko tika he pou pai me he pou kino.
Nā te mea kua mārama te hiko ac me te hiko dc, he aha te hiko toru-wāhanga? E ai ki te ariā, ko te aukume whakawhiti-wāhanga-toru he momo tuku hiko, e kiia nei ko te hiko toru-wāhanga, he mea tito mai i ngā pūmanawa whakawhiti-wāhanga e toru me te auau ōrite, te kaha ōrite me te rerekētanga wāhanga o te 120 nekehanga i ia wā.
I te nuinga o te wā, ko te hiko hurihuri e toru o tō mātou whare, me te ngaohiko, te auau, me te koki o te taraiwa he rerekē, he rite tonu ētahi atu, inaianei kua māramahia te hiko toru-wāhanga me te hiko tika.
Kore paraihe, ko te whakaurunga he au tika, mā te pūnga tātari hei whakau i te ngaohiko. Kātahi ka wehea kia rua ngā ara, ko te huarahi katoa e whakahaerehia ana e te hiko BEC, ko te BEC mō te kaiwhiwhi me te MCU e whakahaerehia ana e te hiko e whakamahia ana i roto i te tuku hiko, ko te putanga ki te kaiwhiwhi o te taura hiko ko ngā rārangi whero i runga i te rārangi me te rārangi pango, ko tetahi atu e uru ana ki te ngongo MOS hei whakamahi i te huarahi katoa, i konei, ko te hiko e whakahaerehia ana e te hiko, ka tīmata te SCM, ka akiaki i te wiri o te paipa MOS, ka puta te tangi o te motuka.
Ko ētahi whakatikatika hiko he mahi whakatikatika tere. I mua i te urunga ki te pūnaha tatari, ka aroturukihia e ia mēnā kei te teitei, kei te iti rānei te tūranga o te tere, kei waenganui rānei. Mēnā kei te teitei te tūranga o te tere, ka uru ki te whakatikatika o te haerenga whakatikatika hiko.
Ina rite katoa ngā mea, ka whakatauhia e te rorohiko iti maramara-kotahi i roto i te whakatikatika hiko te ngaohiko putanga me te auau me te ahunga taraiwa me te koki whakauru hei akiaki i te tere o te motuka me te huri kia rite ki te tohu i runga i te raina tohu PWM. Koinei te kaupapa whakarerekētanga hiko kore paraihe.
Ina oma te motuka taraiwa, e toru ngā rōpū ngongo MOS e mahi ana i roto i te whakarerekētanga hiko, e rua i ia rōpū, ko te putanga pai he mana whakahaere, ko te putanga whakahaere kino, ina he putanga pai, he putanga kino, ehara i te mea kino, he tino teitei te putanga o te putanga, kua hangaia he iahiko hurihuri, hei mahi i tēnei mahi, e toru ngā rōpū o tō rātou auau ko 8000 hz. E kōrero ana mō tēnei, he rite anō hoki te whakahaere hiko kore paraihe ki te motuka wheketere e whakamahia ana i runga i te kaitahuri auau, i te kawana rānei.
Ko te tāuru he hiko dc, ko te tikanga he pākahiko lithium. Ko te putanga he hiko ac toru-wāhanga, ka taea te taraiwa tika i te motuka.
Hei tāpiritanga, e toru ngā rārangi tāuru tohu o te kawana hiko kore paraihe o te tauira hau, he tohu tāuru PWM, e whakamahia ana hei whakahaere i te tere o te motuka. Mō ngā tauira rererangi, inā koa mō ngā tauira rererangi tuaka-whā, e hiahiatia ana ngā tauira rererangi motuhake nā te mea he motuhake.
Nā, he aha te take e hiahiatia ai he whakatikatika hiko motuhake mō te quad, he aha te mea motuhake mōna?
E whā ngā OARS o te hoe wha, ā, he āhua whakawhiti ngā OARS e rua. Mā te huri whakamua me te huri whakamuri o te urungi o te hoe ka taea te whakakore i ngā raruraru hurihuri i puta mai i te hurihanga o te mata kotahi.
He iti te whānui o ia hoe, ā, ka marara te kaha whakatere i te hurihuri o ngā hoe e whā. He rerekē ki te hoe tika, kotahi anake te kaha whakatere kore e whakaputa ana i te kaha whakatere kukū e hanga ana i te āhuatanga wiri, e ārai ana i te huri tere o te tinana.
Nō reira, he tino iti te auau o te whakahou i te tohu whakahaere taputapu urungi.
Kia tere ai te urupare a ngā tuaka-whā, hei whakautu i ngā huringa tū o te motuka i puta mai i te nekenekehanga, me whakarite te tere hiko tere teitei. Ko te tere whakahou o te PPM tikanga he 50 hz anake te mana whakahaere hiko. Kāore e tutuki i te hiahia mō te whakahaere tere. Ko te PPM mana whakahaere hiko he PID kua hangaia ki roto i te MCU, ka taea te whakarerekē i te tere o ngā waka rererangi tauira tikanga kia maeneene. Kāore e tika ana mō ngā tuaka-whā. Me tere te urupare ki ngā huringa tere o te motuka tuaka-whā.
Mā te whakatikatika hiko motuhake tere-teitei, te tohu whakahaere tuku atanga pahi IIC, ka taea te whakatutuki i ngā rau mano o ngā huringa tere motuka ia hekona, i roto i te rere tuaka-whā, ka taea te pupuri i te pumau o te wā whakaaro. Ahakoa te pānga ohorere o ngā kaha o waho, kei te mau tonu.
Tērā pea ka pai koe ki:
