Tikanga iahiko taraiwa hiko hiko

Ko nga tohutohu whakaurunga LM331 ko te tohutohu karaka whakauru DIR f0 me te ahunga, ko nga tohutohu e rua i roto i te whakakotahitanga arorau PMM8713 te he noa o te tohu arorau taima. PMM8713 wahanga atekōkiri putanga taha (PIN10 ~ PIN13)Ko te taraiwa o naianei neke atu i te 20 mA, ka taea e ia te arahi i te motini stepper paku. R1, C1 mo te arawhiti ara iahiko aunoa ina whakakā te waea. Tekau manomano R ka mutu wawe i runga i te hiko hei taumata iti, na reira A ~ D te tautuhi aunoa ki te ahua tuatahi. Mēnā he nui ake te mana nekeneke stepper o waho, karekau i ranea te kaha puku taha puku PMM8713, ka peia te hoahoa ara iahiko hiko whakakaha, ka peia he motini stepper. PMM8713 ia wahanga ka tukuna te tohu arorau raupapa whakaputa whakaputa ki te waahanga taraiwa hiko ki roto i te turanga whakahuri hiko o roto (Te matiti ranei) Tohu Puku. aratau puku nekeneke Stepper rite ki te wāhanga awhiowhio i roto i te nāianei hiko ko te kotahi-ara e rua-ara e taea te wehea ki te polarity kotahi me te puku rua, te tikanga, e toru-wāhanga stepper hiko hiakai peia e te polarity kotahi. E ai ki te tātaritanga o te hiko taraiwa hiko me te ngaohiko me te taraiwa o naianei. Ka mau tenei hoahoa i te aratau taraiwa ngaohiko atete raupapa. Whakakotahitia i roto i te wahanga awhiowhio awhiowhio me te kaha o te ātete, i tetahi taha, ka whakaitihia te wa iahiko awhiowhio tonu, te auau iti i te wa ano ka mahi tonu ki te whakawhāiti i te nāianei. Ma te whakamahi i te kaupapa o runga ake nei, i hangaia he kaapene hiko o te kuaha aunoa e te kuaha o te mana whakahuri o runga me te raro o te tuunga o raro, ma te whakamahi i te huringa ara iahiko e rite ana te mahi o te whakahuri rohe e whakaatuhia ana i te ahua 5 LM348 whakatairitehia te rahi o te ngaohiko o te ngaohiko whakauru, kia pai ai te whakahaere i te hikoi hiko e rere ana, e tutakina ana ranei. Ko tana kaupapa mahi; LM348 i roto i-waahanga whakauru mo te ngaohiko tohutoro, te whakauru whakamuri ki te whakatairite i te whakauru ngaohiko, ka whakatairitehia te ngaohiko i te ngaohiko whakauru he iti iho i te ngaohiko tohutoro, LM348 1 pin putanga taumata tiketike, hanga te BD237 conduction, kia taea e te nekeneke stepper mohio whakamua ranei whakamuri; Ina whakatairitehia te ngaohiko i te ngaohiko whakauru he teitei ake i te ngaohiko tohutoro, 1 titi i runga i te LM348 putanga taumata iti, BD237 tapahi-atu, hikoi hikoi hikoi. Te ara iahiko taraiwa e whakaatuhia ana i te ahua 4. Te parenga o waho Rt me te kaha Ct, te whakatairite taima o roto, te kore transistors, R -S he keu ina he ara iahiko pumau kotahi. Ina nui ake te ngaohiko whakauru Vi + i te ViAt te ngaohiko whakauru, f0 arorau whakaputa taumata iti. I te wa ano, mo te capacitance CL ka tohutohutia puna IR nāianei. Vcc te tuku hiko me te parenga Rt o te capacitive Ct ki te whakakii. A, no te neke atu i te rua-hautoru o Vcc te pūnga ngaohiko utu i nga pito o te Ct, putanga, f0 arorau putanga taumata tiketike. Ka mutu te karaka whakaputa tohu F0 ki nga maramara PMM8713, te auau i muri i te maimoatanga o te PMM8713, te putanga o te A, B, C te tohu taraiwa waewae ki te whakahaere i te wa whakawhiti mana transistor, ki te whakahaere i te tere o te motika stepper. Ara iahiko mana whakahaere hanga o LM348 wha iahiko whakakaha whakahaere whānui. Te ahunga o te tohu mana o waho ma te whakatairite i te LM348 me te iahiko tohutoro ngaohiko. Ina nui ake te Vdi i te ngaohiko tohutoro VH, he pai te whakaputanga U3A, me nga waewae PMM8713, ko te putanga mana whakaputa 4 ko te raupapatanga pupuhi. Ina he iti iho te Vdi i te VH ngaohiko tohu, he kino te whakaputa, me te PMM8713 waewae, 4 te mana whakahaere i te whakaputanga o te wahanga toraro te raupapatanga o te ngaohiko, te waahanga e rite ana ki te putanga o te taraiwa whakamuri me te whakamuri i te raupapa pupuhi, na reira ki te whakahaere i te motika hiko me te hurihuri.
