Akohia ia taahiraa kia mōhio ai koe ki te whakamahi i te motuka DC i roto i te wheketere mīhini kai

I tēnei wā, he nui rawa ngā wheketere mīhini kai, kei ngā tāone nui anake, hei tauira, te mīhini tākai He mea motuhake ake ngā wheketere Ry, ngā wheketere kohua hanawiti, ngā wheketere takahurihuri, ngā wheketere Parai, pērā i ngā wheketere taputapu horoi. Kāore he iti o te whakamahi i te motuka DC i roto i te hanga taputapu o ēnei wheketere mīhini kai. Ko te whakarōpūtanga o te motuka DC e whai ake nei.

1. Ka whakamahia e ngā wheketere mīhini kai te motuka dc e ai ki te whakarōpūtanga paraihe

Kāore he paraihe, kāore he paraihe. Kei te huri tonu te motuka DC i runga i te papa aukume o te rotor, ā, kei runga tonu i te papa aukume o te stator, ka kukume ngā mea rerekē. I te wā tika ka huri i te iahiko mā te takai, ki te kore, kāore e taea te huri i te rotor noa.

(1) He mōtini paraihe

Me te paraihe paraihe, ka whakamahia te motuka DC, e mōhiotia whānuitia ana ko te paraihe). Ka whakawhirinaki ki te motuka paraihe whakawhitiwhiti (e mōhiotia whānuitia ana ko te whakawhitiwhiti). Ā, mā te paraihe me te polarity iahiko whakawhiti, ka oti aunoa te hurihanga o te whakawhitiwhiti me te paraihe i roto i te motuka. E rua ngā momo motuka paraihe: tere teitei me te tere iti. E rua noa ngā momo taura o waho o te motuka paraihe.

Ko tētahi o ngā tino take o te tere o te rahunga o te mōtini paraihe: he ngāwari te pakaru o te paraihe mō te kakahu māmā; tuarua, he ngoikore te āhua whakamatao o te maitai aukume, he ngāwari ki te tango i te aukume. Ehara i te mea ko te wā anake te mea e pā ana ki te kakahu o te paraihe, engari e pā ana hoki ki te rahi o nāianei me te ihirangi koura o te paraihe, nō reira ko te nuinga o te roa o te mahi a te paraihe he tata ki te 200. Nā te nui o te ia o te mōtini raupapa, he māmā ake te whakakapi i te 200, ā, he uaua te huri i te mōtini wira me te momo mōtini pou (e mōhiotia ana ko te mōtini o).

(2) Mōta kore paraihe

Kāore te mōtini kore paraihe e whakamahia he mōtini paraihe. Hei whakatutuki i ngā nekehanga kore paraihe, ka whakamahia ngā transistors me te pūoko tūnga (te huānga Hall) hei utu mō te paraihe me te kaitahuri. Nā tēnei momo mōtini ka whakakorehia te paraihe me te kaitahuri, nō reira ka whakakorehia te pokanoa hikohiko, ehara i te mea ka whakaiti noa i te haruru miihini, engari ka roa ake te ora o te mahi. Engari he uaua ake tēnei momo huānga whakahaere mōtini (te taraiwa mōtini me te ara iahiko whakahaere), ka piki ake te utu, ā, ka iti te wiri i te tīmatanga i te tere iti.

2. Ka whakamahia e te wheketere mīhini kai te motuka dc e ai ki te whakarōpūtanga o te aukume roa

E ai ki te roa o te noho mai o te aukume, ka taea te wehewehe i te motuka hiko aukume wai me te motuka raupapa kia rua ngā akomanga.

(1) Mōta aukume tuturu

Ko te rotor me te stator he motuka aukume tuturu, kotahi anake te mea i hangaia ki te takai waea enamel (e mōhiotia whānuitia ana ko te mōkihi raina), ko tētahi atu he mea whakamahi i te aukume mō te wā roa, e kiia ana hoki ko te maitai aukume). E rua ngā momo motuka kore paraihe me te motuka kore paraihe i wehea ai te motuka aukume tuturu.

(2) Mōta raupapa

Mō te motuka raupapa, kāore he aukume, ka whakamahia te takai rotor me te stator, ā, ka whakamahia ngā takai e rua i roto i te raupapa, nō reira ka kiia tēnei momo motuka he motuka raupapa. I roto i ēnei, ka puta he mara aukume whakaohooho i te takai stator o te papa aukume.

E rua ngā rārangi o te motuka raupapa me te huānga whakahaere, engari kāore i rite ki te aukume tuturu he motuka paraihe kei a ia. Mā te whakawhiti i te āpitihanga ka taea te whakarerekē i te ahunga o te hurihanga o te motuka, engari mā te whakawhiti i te takai rotor, (He takirua rārangi) te takai stator rānei (He takirua rārangi) te whakarerekē i te ahunga o te hurihanga.

3. Te wheketere mīhini kai e whakamahi ana i te whakarōpūtanga o te tere hurihuri o te motuka dc

I ngā wāhi o te tere hurihuri, ka taea te wehewehe i te motuka kia rua ngā momo: te tere teitei me te tere iti. Ko te tere teitei ake i te 3000/min ka kiia he motuka tere-teitei, ko te motuka i te tere iti iho i te 1000/min ka kiia he motuka. I tēnei wā, kei reira ngā motuka porowhita taputapu paraihe e tata ana ki te 200 rpm ka taea te mahi. Nā te tere teitei o te motuka, ko te tere hurihuri he 3000 ~ 5000/min, ā, ko ngā mea e hiahiatia ana e te pahikara hiko:

(1) Ko te tere o te mōtini tere-rahi he tata ki te 200/min, kia taea ai te whakahaere i te tere kore-taahiraa 0 ~ 20 km/h, me whakamahi mā te taputapu whakaiti me te mamau, nō reira he mōtini tere-rahi ngā mōtini taputapu. Kua tāutahia ētahi mōtini tere-rahi me ētahi taputapu whakaiti, ā, ko ētahi ka tāutahia ngā taputapu ki roto i te mōtini, pērā i te mōtini pokapū taputapu paraihe, te taputapu ki roto i te motuka.

Ko te wheketere mīhini kai i runga ake nei ko te whakamahinga o te whakarōpūtanga o te motuka dc, ko te tumanako ka āwhina i a koe.
