Stepper motor - zizindikiro za kusagwira ntchito ndi kuwonongeka. Momwe mungayeretsere stepper motor m'galimoto?

Mu injini zoyatsira zamkati zamafuta, stepper motor ili pafupi ndi valavu yamoto. Ichi ndi kachipangizo kakang'ono kamene kamayang'anira malo osagwira ntchito kuti chigawocho chisasiye kugwira ntchito pamene accelerator pedal imatulutsidwa. Imasintha nthawi zonse ntchito yake ku magawo a injini yapano, kuonetsetsa kuti ikuthamanga kwambiri. Werengani kuti mudziwe za kapangidwe ndi kachitidwe ka stepper motor m'galimoto. 

Kodi stepper motor ndi chiyani?

Mwachidule, mota ya stepper, yomwe imatchedwa valavu ya stepper kapena valavu yogwira ntchito pang'onopang'ono, ndi mota yamagetsi yomwe imazungulira rotor kudzera muzinthu zina zamakona kutengera ma pulses omwe amagwiritsidwa ntchito. Mu injini kuyaka mkati, zinthu zingapo zimakhudza ntchito yake, kuphatikizapo:

• Kutentha kozizira;
• crankshaft udindo sensa chizindikiro;
• Kuwerenga kwa sensa ya MAP;
• zambiri za kuyatsa pa;
• mlingo wa batri.

Chifukwa cha zomwe zili pamwambapa, stepper motor imagwira ntchito yake, ikugwirizana ndi kutentha kwa injini kapena kufunika kowonjezera batire. 

Kodi stepper motor imagwira ntchito bwanji?

Mfundo yogwiritsira ntchito injini ya stepper imachokera ku mgwirizano wa rotor yosangalatsa, cholumikizira mphamvu ndi valavu yozungulira. Chipangizochi chimayang'anira polarity yapano yomwe imaperekedwa kumagetsi, ndipo motero imatsimikizira kukhazikitsidwa kwa ngodya ya kupendekera.

Liwiro la injini limawongoleredwa ndi zambiri kuposa pedali yothamangitsira. Pali nthawi zina zomwe muyenera kuchita popanda iye kutenga nawo mbali, monga kuyimirira pamseu wapamsewu kapena kuyandikira maloboti. Ndikofunika kuti sikumangokhalira kusunga liwiro pamlingo womwe wapatsidwa, komanso kuyang'anira ntchito ya injini m'njira yoti mukhalebe ndi batire, kugwiritsa ntchito machitidwe onse komanso nthawi yomweyo kuwotcha mafuta pang'ono. momwe zingathere. RPM imatha kusiyanasiyana kutengera kutentha kwa injini ndi kuchuluka kwa batire.

Kuzungulira chipwirikiti - zizindikiro za kulephera ndi kuwonongeka kwa stepper motor

Zolakwa ndi kuwonongeka kwa valavu ya sitepe ndizosavuta kuzindikira. Ma stepper motor amawonetsa kulephera mwa kusinthasintha pa liwiro lachabechabe kapena kumawonjezera nthawi zonse, mwachitsanzo, poyandikira magetsi. Gwirizanani, zingakhale zokwiyitsa pamene simungathe kuzitsitsa ndipo galimoto imayamba kulira mopanda chifundo pa liwiro lalikulu. Nthawi zambiri, khalidwe chipika ichi amayamba chifukwa ntchito molakwika stepper galimoto.

Zoyenera kuchita ngati muwona zizindikiro za kuwonongeka kwa valve stepper?

Pali njira zingapo zothanirana ndi valavu yowonongeka ya stepper. Tiyeni tiyambe ndi mfundo yakuti nthawi zambiri kukonzanso kumatha kuchita paokha. Ndi za kuyeretsa stepper motor. Pansipa tikufotokoza ndondomekoyi mwatsatanetsatane.

Kuyeretsa kapena kusintha mota ya stepper?

Ngati mukukayika ngati kuli bwino kuyeretsa kapena kusintha stepper motor, onani momwe gawoli lilili. Yang'anani valavu ya siteji pafupi ndi throttle. Ikhoza kuphatikizidwa ndi gawo lina la njira yoyamwa, choncho nthawi zonse muyenera kuyang'ana galimoto ya stepper m'derali. Ndikofunika kuzindikira kuti m'malo mwa stepper motor nthawi zambiri sikofunikira. Nthawi zambiri zimakhala kuti ntchito yolakwika ya stepper motor imayambitsidwa ndi zonyansa zomwe zimasonkhana mkati mwa chinthu ichi.

Momwe mungayeretsere stepper motor?

Yambani kuyeretsa mota ya stepper pochotsa zinthuzo. Pezani malo aukhondo omwe mungapatule mosavuta. Pambuyo poyeretsa bwino mbali zonse za stepper motor, perekani mafuta omwe ali ndi udindo wokankhira pulagi. Mukabwezeretsa zonse m'njira yoyenera, mutha kuyika valavu yopanda ntchito.

Kusintha kwa valve

Kuyika magawowo ndikuyendetsa gawolo, mudzawona kuti sizinthu zonse zomwe zimagwira ntchito momwe ziyenera kukhalira. Izi ndichifukwa choti stepper motor iyenera kusinthidwa. Kodi kuchita izo? Yatsani choyatsira ndikutsitsa chowongolera kangapo ndikuchimasula pang'onopang'ono. Mu zitsanzo zina zamagalimoto, njira iyi ndi yokwanira ndipo imakulolani kuti mubwerere ku zoikamo fakitale ya stepper motor.

Komabe, nthawi zina zambiri zimafunika kuchitidwa. Ngati liwiro la injini likadali losinthasintha, yambitsani injiniyo ndikuisiya ikugwira kwa mphindi zingapo. Izi zitha kupangitsa kuti "ipeze" zosintha za chipangizocho ndikuyamba kugwira ntchito momwe zimayembekezeredwa. Njira ina ndikudutsa njira ya 15-20 km. Ilinso mtundu wa kusintha kwa zinthu. Ngati zonsezi sizikuthandizani, motor stepper iyenera kusinthidwa. Komabe, musanachite izi, yesani kugwiritsa ntchito njira zonse zomwe zilipo.

Ntchito yopangidwa ndi stepper motor ndiyofunika kwambiri. Chofunika kwambiri, kapangidwe kake ndi kophweka kotero kuti mutha kuyeretsa stepper motor nokha. Ngati izi sizikuthandizani, mwatsoka muyenera kusintha valavu ya siteji. Mwamwayi, sizokwera mtengo.
