Ngā Mōta Kore Paraihe me ngā Mōta Paraihe: Ko tēhea te mea e tika ana mō tō kaupapa?

Kupu Whakataki

E rua ngā momo motuka DC e kitea whānuitia ana, ko ngā motuka paraihe me ngā motuka kore paraihe (ngā motuka BLDC). E ai ki te ingoa, ka whakamahia e ngā motuka paraihe ngā paraihe hei whakawhiti i te ahunga, kia taea ai e te motuka te huri. He rerekē, ka whakakapia e ngā motuka kore paraihe te mahi whakawhiti miihini ki te mana hiko. Ka mahi ngā momo e rua i runga i te kaupapa kotahi, arā, te kukume aukume me te pana aukume i waenga i te koiri me te aukume tuturu. He painga me he ngoikoretanga o ia momo, ka pā pea ki tāu whiringa i runga i ngā whakaritenga motuhake o tō tono. He mea nui te mārama ki ngā rerekētanga i waenga i ngā motuka DC paraihe me ngā motuka DC kore paraihe hei aromatawai i tā rātou mahi. Ko te whakatau ki te whiriwhiri i tētahi momo i runga i tētahi atu e ahu mai ana i ngā paearu maha, tae atu ki te whai huatanga, te roa o te ora me te utu.

Ngā āhuatanga nui mō te rerekētanga i waenga i te motuka DC paraihe me te motuka kore paraihe:

#1. Pai ake te Whai Hua

He pai ake te mahi a ngā mōtini kore paraihe i ngā mōtini paraihe. Ka hurihia e rātou te pūngao hiko ki te pūngao miihini me te tino tika, ā, ka whakaitihia te moumou pūngao. Kāore i rite ki ngā mōtini DC paraihe, kāore ngā mōtini kore paraihe e pāngia e te waku, te ngaronga pūngao rānei e pā ana ki ngā paraihe me ngā kaitahuri. Ka whakapai ake tēnei i te mahi, ka roa ake te wā oma, ā, ka whakaitihia te whakapaunga pūngao.

I tetahi atu taha, e kiia ana he iti ake te whai huatanga o ngā motuka paraihe i ngā motuka DC kore paraihe nā te ngaronga o te mana e pā ana ki te waku me te whakawhiti pūngao i roto i te pūnaha whakawhitiwhiti.

#2. Te Tiaki me te Roa o te Ora

Ngā motuka kore paraihehe iti ake ngā wāhanga neke, ā, kāore he hononga miihini, ka roa ake te ora me te whakaiti i ngā whakaritenga tiaki. Nā te korenga o ngā paraihe ka kore e raru ngā raruraru e pā ana ki te pakaru o te paraihe me ētahi atu take tiaki. Nō reira, he maha ngā wā he kōwhiringa utu pai ake ngā motuka kore paraihe mō ngā kaiwhakamahi.

Hei tāpiritanga, me nui ake te tiaki i ngā mōtini paraihe nā te mea kua pakaru ngā paraihe me te commutator, ka heke pea te mahi me ngā raruraru mōtini. Hei pupuri i te mahi tino pai, me whakakapi ngā paraihe i ia wā.

#3. Haruru me te Wiri

I roto i ngā motuka kore paraihe, ka taea te whakahaere i te ia hurihuri, ka āwhina i te whakaiti i ngā pao o te taipana ka puta ai te wiri me te haruru miihini. Nō reira, ko te tikanga he iti ake te haruru me te wiri o ngā motuka kore paraihe i ngā motuka paraihe, nā te mea kāore he paraihe, he kaitahuri rānei. Mā te whakaiti i te wiri me te haruru ka pai ake te whakamarie o te kaiwhakamahi, ā, ka whakaitihia te pakaru me te haehae i te whakamahinga roa.

I roto i te motuka DC paraihe, ka mahi tahi ngā paraihe me te commutator hei tikanga whakawhiti. Ina oma te motuka, ka tuwhera tonu, ka kati tonu ēnei pana. Mā tēnei tukanga ka taea e ngā iahiko teitei te rere mā roto i ngā takai rotor whakaawe, ka puta he haruru hiko iti nā te nui o te iahiko.

#4. Te Utu me te Uauatanga

He nui ake te utu me te uaua o ngā motuka kore paraihe nā te pūnaha whakahaere hiko mō te whakawhiti. Ko te utu teitei ake o ngā motuka DC kore paraihe ki te whakaritea kingā motuka DC paraihenā ngā taputapu hiko matatau i roto i tā rātou hoahoa te nuinga.

#5. Te Hoahoa me te Whakahaere

Kāore ngā motuka DC kore paraihe e huri aunoa. Me whai ara iahiko taraiwa e whakamahi ana i ngā transistors hei whakahaere i te ia e rere ana i roto i ngā koiri takai motuka. Ka whakamahia e ēnei motuka ngā mana hiko me ngā pūoko pānga Hall hei whakahaere i te ia i roto i ngā takai, kaua e whakawhirinaki ki ngā hononga miihini.

Ka taea e ngā motuka DC paraihe te huri i a rātou anō, arā, kāore e hiahiatia he ara iahiko taraiwa hei whakahaere. Engari, ka whakamahia e rātou he paraihe miihini me ngā kaitahuri hei whakahaere i te iahiko i roto i ngā takai, ā, ka hangaia he papa aukume. Ka hangaia e tēnei papa aukume he taipana, ka huri ai te motuka.

#6. Ngā tono

I te mea ko te utu ongā motuka wiriā, kei te heke haere tonu ngā hikohiko e pā ana ki aua mea, kei te piki haere te hiahia mō ngā motuka kore paraihe me ngā motuka paraihe. He tino rongonui ngā motuka kore paraihe mō ngā mataaratanga atamai, ngā taputapu hauora, ngā taputapu ataahua, ngā karetao, me ētahi atu.

Engari kei reira tonu ngā wāhi e tika ana te whakamahi i ngā mōtini paraihe. He nui te whakamahinga o ngā mōtini paraihe ki ngā waea atamai, ki ngā hikareti hiko, ki ngā pūmana kēmu ataata, ki ngā mīhini mirimiri kanohi, me ētahi atu.
