Me pēhea te whakamahi i te pupuhi kore paraihe DC: He aratohu katoa
He mea nui ngā pupuhi kore paraihe DC i roto i ngā mahi hou maha, mai i ngā taputapu hauora me ngā pūtau wahie ki ngā pūnaha whakamatao me te horoi hau ahumahi. E mōhiotia ana mō te pai o te mahi, te rahi kiato, me te whakahaere tere tika, me whakarite me te whakahaere tika ēnei pupuhi kia haumaru ai, kia pono ai hoki te mahi. Kei roto i tēnei tuhinga he aratohu taipitopito taahiraa-i-te-taahiraa mō te tāuta tika, te whakahaere, me te rapu raruraru i tētahi pūnaha pupuhi kore paraihe DC i runga i te pukapuka tohutohu hua paerewa.
1. Kia Mārama ki ngā Wāhanga o te Pūnaha
I mua i te whakamahi i te pupuhi kore paraihe DC, he mea nui kia mārama ki ngā wāhanga matua o te pūnaha:
-
Pūtake Mana DC: Ka tuku hiko DC ngaohiko iti ki te pupuhi.
-
Waea ManaKa hari i te hiko mai i te pūtake ki te kaiwhakahaere.
-
Kaiwhakahaere: Whakahaere i te tere me te mahi a te pupuhi.
-
PūpuhiKo te waeine pā hau e whakahaerehia ana e te motuka e neke ana i te hau.
-
PūmanahikoHe poroporo ā-ringa e taea ai e ngā kaiwhakamahi te whakahaere i te tere o te pupuhi.
Me hono tika, me tāuta hoki ia wāhanga i mua i te whakakānga i te pūnaha.
2. Ngā Aratohu Haumaru
Me noho te haumaru ki te tuatahi i te wā e mahi ana me ngā taputapu hiko me ngā taputapu mīhini. Whāia ēnei tohutohu haumaru hei karo i te pakaru, i te whara rānei:
-
Āraia te pā ki te putanga haui te wā mahi hei ārai i te whara.
-
Whakamaua kia maute pupuhi i mua i te tīmatanga hei ārai i te nekehanga, i te wiri rānei.
-
Kia tino mohio kei kore te pupuhi emanawahia te wai, te hau waikura, ngā wai rānei, ka kino pea ngā wāhanga o roto.
-
Whakahaerehia te pupuhi i roto i ngā taiao me ngā pāmahana i waenga i te-20°C me te 60°C. Mēnā ka whakamahia i waho o tēnei awhe, ka raru pea te mahi.
3. Te Hononga me te Whakakaha i te Pūwero
He mea nui te whakamahi waea tika mō te mahi haumaru me te whai hua:
-
Honoa tewaea wheroki te pito pai (+) o te pūtake hiko me tewaea pangoki te pito kino (-).
-
Me whakarite kia tika te hiko o te pūhikoe ōrite ana ki te ngaohiko kua whakatauria o te pupuhi, ā, ko te putanga o nāianei koteitei ake i te iahiko whakatauranga mōrahi o te pupuhi.
Kia oti te hono waea, tirohia anō ngā hononga katoa mō te tika me te haumaru i mua i te whakakā i te taputapu.
4. Te Whakahaere i te Tere o te Pūwero
He maha ngā huarahi e tukuna ana e ngā pupuhi kore paraihe DC hei whakahaere i te tere, he mea tino whai hua mō ngā momo whakamahinga rerekē.
a. Mana Whakahaere Pūtake
Mena kei roto i te pūnaha he potentiometer:
-
Te huri i te porowhitate taha matau ki te taha matauka tīmata te pupuhi.
-
Ka piki haere te tere i te tahuritanga tonu o te poroporo.
He ngāwari te whakamahi i tēnei tikanga, ā, he pai mō ngā taiao whakarerekētanga ā-ringa.
b. Mana Whakahaere Ngaohiko Analog (0–5V)
Mena e hiahiatia ana he mana hiko pai ake:
-
Tangohia te potentiometer.
-
Tāpirihia heTohu DC 0–5Vi waenganui i tewaea whakahaere hiname tewaea whenua pango.
-
Mā te whakanui ake i te ngaohiko mai i te 0V ki te 5V ka piki ake te tere o te pupuhi.
He pai rawa tēnei tikanga mō ngā pūnaha e hiahia ana ki te whakarite aunoa i te tere o te pupuhi i runga i ngā pūoko, i ētahi atu tāurunga whakahaere rānei.
c. Mana Whakahaere PWM
Mō ngā pūnaha matihiko matatau:
-
Tangohia te potentiometer.
-
Tāpirihia hePWM (Whakarerekētanga Whānui Pāorooro)tohu i waenganui i tewaea hiname tewaea pango.
-
Me whai te kaha o te tohu i te5Vme te auau i waenganui i2kHz me te 50kHz.
He tikanga whānui te PWM i roto i ngā pūnaha whakahaere tāmau nā te mea he ngāwari, he pai hoki te whakamahi i te pūngao.
5. Ngā Āhuatanga Mahi Tāpiri
He maha ngā mahi atamai kua hangaia ki roto i ngā pupuhi kore paraihe DC:
-
Whakahohe/Monohia te Mahi:
Te hono i tewaea papuraki tewaea pangoKa mutu te pupuhi. Mā te momotu i a rātou ka taea te whakahaere. He mea whai hua tēnei mō te whakahaere whakaweto/whakakā mamao. -
Te Hurihanga Aronga:
Te hono i tewaea matomatoki tewaea pangoka huri i te ahunga hurihuri o te motuka. (Kia mahara: Ka pā tēnei ki ngā motuka anake, kaua ki ngā wae pupuhi kua whakaritea te ahunga o te hau.) -
Urupare Tere (Tohu FG):
Tewaea māe whakarato ana i te putanga pātītī hei aroturuki i te tere.-
MōTauira WS7040, ko ia Hz e rite ana ki te 60 RPM.
-
Mōētahi atu tauira, 1 Hz = 30 RPM.
-
-
Te Parenga Werawera:
Ka tautokohia e ētahi pupuhi he ātete wera e whakaweto aunoa ai i te motuka mēnā ka piki ake te pāmahana o roto i tētahi paepae haumaru.
6. Te Whakahaere me te Rokiroki
He mea nui te tiaki me te rokiroki tika hei pupuri i te mahi a te pupuhi me te whakaroa i tōna roanga ora:
-
Penapena ki te taiao marokehei ārai i te waikura o roto.
-
Kaua e wetewete i te impeller, nā te mea ka puta te kore taurite me te haruru.
-
Me whakarite kia rere te impeller i roto i tete taha whakamuri (CCW)te ahunga mahi tika, arā, te aronga tika.
7. Te Whakatau i ngā Raruraru me ngā Waehere Hapa LED
Mena kāore te pupuhi e mahi tika ana, ka taea e ngā tohu LED kua whakauruhia te āwhina ki te tautuhi i te raruraru:
-
E kā ana ngā LED e ruaKua wera rawa te motuka, te taraiwa rānei.
-
Ngā tauira kanapa puhoi LED2:
-
2 ngā wā: Ngaohiko iti iho, ngaohiko nui rawa rānei.
-
3 ngā wā: Hapa tauira o nāianei, raruraru waea rānei.
-
4 ngā wā: Kua mau te motuka.
-
5 ngā wā: Te rahunga o te wāhanga.
-
6 ngā wā: Hapa o te pūoko whare.
-
-
Ngā tauira kanapa tere LED2:
-
1–4 ngā wā: Ngā raruraru ara iahiko taraiwa, ngā ara iahiko poto rānei.
-
-
LED2 whakawetoKei te oma noa te mōta.
-
Uira ōrite LED2Kua mutu te motuka i te āhua noa (kāore he tāuru tere).
-
Te rama tere LED2 e 4 ngā wāKua whakahohehia te parenga iahiko nui.
Tirohia te pukapuka kaiwhakamahi, te kaihanga rānei mō ētahi atu tātaritanga mēnā e tika ana.
Whakamutunga
He māmā noa te whakamahi i tētahi pūwero kore paraihe DC ina mārama koe ki ōna wāhanga me āna mahi. Ahakoa kei te whakarerekē koe i te tere mā te potentiometer, te ngaohiko anaro, te tohu PWM rānei, ka tukuna e ēnei pūwero he mahi ngāwari, marino, me te pono. Me whai tonu i ngā aratohu haumaru me ngā tohutohu waea, ā, whakamahia ngā tohu urupare me ngā tohu hapa kua hangaia hei aroturuki i te tūnga o te pūnaha.
Mā te whakamahinga tika me te tiaki, ka tukuna e tō pupuhi he mahi pumau i roto i ngā mahi katoa—ahakoa he whakakaha i tētahi mīhini manawa hauora, he tautoko i tētahi pūtau wahie hauwai, he whakamatao rānei i ngā hikohiko tairongo.
