Ngā Mōta Wiri Kore Paraihe me ngā Mōta Wiri Paraihe: Ko tēhea te Mea Tika mō tō Pūrere?

I te wā e whiriwhiri ana i ngā motuka wiri mō ngā taputapu kiato, ko te whiriwhiri i waenga i ngā motuka BLDC iti (diameter 5mm-12mm) me ngā motuka paraihe iti (diameter 7mm-12mm) ka taea te whakatau i te mahi a te hua, te roa o te ora, me te wheako kaiwhakamahi. Ka hurihia e rāua te pūngao hiko ki te nekehanga hurihuri hei whakaputa wiri, engari ko ō rāua rerekētanga hoahoa ka puta he painga motuhake mō ngā tono motuhake. Kei raro nei he whakataurite whānui hei ārahi i tō whakatau—me ngā māramatanga ki ā mātou otinga motuka ritenga.

Ngā Rerekētanga Hanganga Matua

Ko te rerekētanga matua kei roto i te āhua o te whakawhiti i waenga i ia motuka (te whakahaere i te ahunga o ia au), e pā ana ki te roa, te whai huatanga, me te uauatanga.

Ngā Mōta Kore Paraihe Iti(5mm-12mm)

Ka whakakorea e ēnei motuka ngā paraihe waro me te kaitahuri miihini e kitea ana i roto i ngā hoahoa tuku iho. Engari, ka whakawhirinaki rātou ki ngā kaiwhakahaere hiko me ngā pūoko Hall hei whakahaere i te rere o te iahiko ki ngā takai stator. Ko ngā āhuatanga hanganga matua ko:

• Whirihoranga o te stator-rotor: He stator tūmau me ngā aukume tuturu me te rotor takai-koi hurihuri (tērā pea i ētahi hoahoa).

• Ngā hikohiko whakauru: He maha ngā motuka BLDC iti e whakauru ana i ngā IC taraiwa, e whakangāwari ana i te whakaurunga ki ngā PCB taputapu me te kore e pokanoa ki te hikohiko.

• Ngā whanaketanga rauemi: Ka whakanui ake ngā aukume Nd-Fe-B mahi-teitei me ngā anga konumohe koranu i te kiato mana me te marara wera.

Ka whakakorehia e te hoahoa kore paraihe te pā o te tinana i waenga i ngā wāhanga e neke ana, ka whakaitihia te waku me te pakaru—he mea tino nui tēnei mō te pono mō te wā roa.

Ngā Mōta Paraihe Iti(7mm-12mm)

He hangarau rautau te pakeke, e whakamahi ana ēnei motuka i tētahi pūnaha miihini māmā noa iho:

• Ngā paraihe waro + te kaitahuri: Ka whakawhitihia te iahiko e ngā paraihe ki ngā aukume hiko o te rotor mā te reti ki tētahi kaitahuri kua wehea, e huri ana i te ahunga o te iahiko hei pupuri i te hurihanga.

• Hanganga māmā: Mā te iti o ngā wāhanga (kāore he pūoko, he kaiwhakahaere rānei) ka iti ake ngā utu hanga engari ka whakawhāiti i te mahi.

• Ngā momo matua: Ko ētahi motuka paraihe he hoahoa rotor kore matua (he koiri āhua kapu) hei whakaiti i te ātete, ahakoa kei te whakawhirinaki tonu ki ngā paraihe konganuku utu nui mō te whakawhiti.

Ahakoa te utu whaitake, ka hangaia e te atanga paraihe-whakawhitiwhiti he herenga ā-roto ki te roa o te whakamahinga me te whai huatanga.

Whakataurite Rahi me te Āhua

E rua ngā momo motuka e aro ana ki ngā tono kiato, engari he rerekē ngā whānuitanga rahi me te ngāwari o te hoahoa:

Ngā Ahu o te Mōta Kore Paraihe Iti

• Te whānuitanga o te diameter: 5mm ki te 12mm (hei tauira, ngā motuka āhua-panikeke 5mm×2.5mm).

• Painga matotoru: Nā te matotoru rawa (tae atu ki te 1.8mm) he mea tino pai mō ngā taputapu mau me ngā taputapu angiangi pērā i ngā mataaratanga atamai.

• Ngā āheinga o te whakairi: Ngā kōwhiringa mō te whakapiripiri, te waea mata, te FPCB, te whakairi puna rānei hei urutau ki ngā wāhi kua herea.

I te pito 5mm, ko ngā mōtini kore paraihe iti rawa te otinga wiri iti rawa e taea ana mō ngā karetao moroiti me ngā taputapu hauora ka taea te whakatō.

Ngā Ahu o te Mōta Paraihe Iti

• Te whānuitanga o te diameter: 7mm ki te 12mm (e whakawhāitihia ana e te hiahia ki te whakauru i ngā paraihe me ngā commutator).

• Ngā kōtaha noa: Ko ngā motuka paraihe momo-moni (hei tauira, 8mm×2.0mm) te nuinga o tēnei wāhanga, me te waea mata pūmau, te whakamau rānei e hangai ana ki te hononga.

• Ngā herenga rahi: Me iti rawa te āputa o roto mō ngā paraihe, kia kore ai e iti iho i te 7mm ngā diameter, engari me te kore e whakaiti i te mahi.

He iti ake ngā kōwhiringa rahi e tukuna ana e ngā mōtini paraihe engari ka noho whakataetae tonu mō ngā hiahia kiato waenga.

Te Mahi Wiri: He aha te Mea Tino Hira?

Ko te whai huatanga o te wiri e whakawhirinaki ana ki te kaha (g-force), te ōritetanga, te haruru, me te wā urupare—koinei ngā wāhi e tino pai ana te hangarau kore paraihe, me ngā painga motuhake o ngā motuka paraihe.

Ngā Mōta Kore Paraihe Iti

• Putanga wiri whai hua: Ko te whai huatanga pūngao teitei ake (70%+ noa) ka nui ake te wiri mō ia watt, me ngā tauira 12mm e tuku ana i te kaha tae atu ki te 2.0g i te 9,000 RPM.

• Mahi maeneene, mārie: Ko te kore o te waku paraihe he iti noa te haruru oro (he iti iho i te 45dB te nuinga) me te whakaiti i te pokanoa hikohiko—he mea nui mō ngā taputapu mau me ngā taputapu hauora.

• Urupare tere: He iti te ātete hurihuri o ngā hoahoa kore-matua me te kore-moka (he mea noa i roto i ngā motuka BLDC iti), e āhei ai ngā wā pikinga <90ms me te whakahaere wiri tika.

• Mahi pumau: Ko te kore e pakaru te paraihe ka pumau tonu te kaha wiri mō te roanga o te ora o te motuka neke atu i te 20,000 hāora.

Ngā Mōta Paraihe Iti

• Te taipana tīmatanga teitei: Ka kaha ake te wiri tīmatanga mā te whakawhiti ā-ringa, he mea whai hua mō ngā taputapu e hiahia ana ki te urupare haptic tonu (hei tauira, ngā pager).

• He iti ake te pai o te mahi: Ka whakaitihia te putanga e ngā mate waku, ā, ka pau te 48-150mA i te 3V i ngā tauira 12mm (ki te 30mA mō ngā waeine kore paraihe rite).

• Te roa o te ora kāore i te rite: Ka pakaru ngā paraihe i muri i te 1,000-5,000 hāora, ka heke te kaha o te wiri, ka piki ake te haruru.

• Te pokanoa hiko: Ka puta te EMI i te awhiowhio paraihe ka taea te whakararuraru i ngā pūoko me ngā ara iahiko tata.

Ngā Horopaki Taupānga: Tātaitia te Mōta ki tō Pūrere

Ko ngā kaupapa matua o tō whakamahinga—te utu, te roa o te whakamahinga, te rahi, te tika rānei—ka whakatau i te kōwhiringa pai rawa atu.

Ngā Wāhi hei Whakamahi i ngā Mōta Kore Paraihe Iti

Ka tiaho ēnei motuka i roto i ngā tono mahi-teitei, roa te ora:

• Hangarau mau: Ka whai hua ngā mataaratanga atamai me ngā aroturuki hauora i ngā kōtaha angiangi o ngā motuka kore paraihe iti 5-8mm me te mahi mārie.

• Ngā taputapu hauora: Ko ngā taputapu pokanga me ngā aroturuki kawe e whakawhirinaki ana ki te tika o ngā motuka BLDC iti 10-12mm me te roanga mahi 20,000-hāora.

• Ngā pūoko ahumahi: Ka whakamahia e ngā pūoko me ngā matawai te wiri kore paraihe hei whakahoki urupare pumau i roto i ngā taiao uaua (-30℃ ki te 85℃).

• Ngā taputapu kāinga atamai: Ka whakamahia e ngā pūoko IoT me ngā taputapu iti ngā motuka paraihe iti, whai hua, iti-EMI.

Ngā Wāhi hei Whakamahi i ngā Mōta Paraihe Iti

He tino pai ngā motuka paraihe mō ngā hua iti te utu, poto ki te waenga te roa:

• Ngā hikohiko kaihoko: Ko ngā taonga takaro utu iti, ngā mana mamao, me ngā taputapu whakakorekore te mea nui ki te utu iti o ngā motuka paraihe 7-10mm.

• Ngā mahi whakapūmau taumata-tīmatanga: Ka whakamahia e ngā pager taketake me ngā whitiki whakapakari tinana utu iti ngā motuka paraihe moni 12mm hei whakatūpato wiri māmā.

• Ngā taputapu hauora whakakorekore: Kāore e hiahiatia he roa te ora o ngā taputapu kotahi-whakamahinga (hei tauira, ngā pene insulin) pērā i ngā tauira kore paraihe.

Ā Mātou Otinga Mōta Ritenga

Ahakoa he motuka paraihe iti 5mm te rahi hei āwhina whakarongo, he motuka paraihe 12mm rānei hei taonga takaro e hiahiatia ana e koe, ka taea e koe te whakarite i a koe anō:

• Whakatakotoranga mahi: Whakaritea te ngaohiko (1.8V-4V), te kaha (0.5g-2.0g), me te RPM (5,000-50,000) kia ōrite ki ngā āhuatanga o tō pūrere.

• Ngāwari o te āhua: Whakaritea ngā taura (waea, FPCB, puna rānei), ngā hononga (JST, Molex), me te whakamau (piripiri, pūmau).

• Te whakapūmau kounga: Ka whakamatautauria ia motuka e ngā tohu e 4 (te mahi, te āhua o te ngaru, te haruru, te āhua) me te tirotiro 200% i mua i te tukunga.

• Te hanga tauira tere: Mā te kaha o te 80 miriona waeine ia tau ka tere te tukatuka i ngā ota ritenga.
