Mitima ya stepper ndi imodzi mwa magalimoto osavuta kuti agwiritse ntchito mu zamakono zamakono komwe kumakhala kosavuta ndi kubwereza. Mwatsoka, kumanga magalimoto oyendetsa malo kumaika malire otsika mofulumira pamoto, motsika kwambiri kuposa liwiro la magetsi kumatha kuyendetsa galimoto. Pamene ntchito yofulumira kwambiri ya injini ya stepper ikufunikanso kuti zovuta zowonjezera ziwonjezeke pamene zifukwa zambiri zimayamba kubwera.
Kuthamanga kwapamwamba kwa Stepper Motor Motor
Zifukwa zingapo zimakhala zofunikira kwambiri komanso zovuta zothandizira kuti magetsi apitirize kuyenda mofulumira. Monga zigawo zikuluzikulu, khalidwe lenileni lapadziko lonse la magalimoto oyendetsa sizolondola komanso kutalika ndi chiphunzitso. Kuthamanga mothamanga mothamanga kwambiri kumakhala kosiyana ndi wopanga, chitsanzo, ndi kuyendetsa kwa galimotoyo ndi msinkhu wa 1000-3000 RPM zomwe zingatheke (pafupipafupi, servo motors ndi abwino koposa). Zinthu zazikulu zomwe zimakhudza kuyendetsa galimoto mothamanga kwambiri ndi:
- Inertia - Chinthu chilichonse chosuntha chili ndi mphamvu zomwe zimatsutsana ndi kusintha kwachangu kwa chinthu. Pakapita mofulumira, ndizotheka kuyamba kuyendetsa galimoto yopita kuwiro mwamsanga popanda kusowa sitepe. Komabe, kuyesa kuyendetsa katundu pamsewu wothamanga mofulumizitsa kwambiri ndi njira yabwino yozembera mapazi ndi kutaya malo. Pokhapokha ngati katundu wolemera kwambiri ali ndi zotsatira zochepa zowonongeka, galimoto yoyendetsa galimoto iyenera kuyenderera kuchoka pamunsi mofulumira kufika kuwiro mofulumira kuti ipitirize kukhala malo abwino ndi olondola. Zida zamakono zoyendetsa galimoto zimaphatikizapo kuchepetsa kuchepa ndi njira zothetsera vutoli.
- Mipikisano Yamtundu - Mphuno ya motolo yoyendetsa siyimira pa liwiro lirilonse koma limathamanga pamene liwiro likufulumira. Chifukwa cha izi chikuchokera pa oyang'anira opanga ma motors. Mbendera yoyendetsa magalimoto yothamanga imapanga maginito m'makina oyendetsa galimoto kuti apange mphamvu kuti itengepo. Nthawi yomwe maginito amafika kuti agwiritse ntchito mphamvu zonse zimadalira kutengera kwa coil, magalimoto oyendetsa galimoto, ndi kuchepa kwamakono. Pamene kuyendetsa galimoto kumawonjezeka, nthawi yomwe ma coil amakhalabe pa mphamvu yawo yonse imatha kuchepa ndipo nthawi yomwe injini imatha kupanga madontho.
- Chizindikiro Choyendetsa - Kuonjezera mphamvu mu injini ya stepper, chizindikiro choyendetsa pakali pano chiyenera kufika pamtunda woyendetsa galimoto pakalipano komanso pamagetsi othamanga kwambiri izi ziyenera kuchitidwa mofulumira. Kuyendetsa galimoto yothamanga ndi mpweya wothamanga kwambiri kungathandize kupititsa patsogolo phokoso lofulumira kwambiri lomwe limagwiritsidwa ntchito mofulumira pazitsulo zoyendetsera galimoto zamakono.
- Zone Yakufa - Lingaliro loyenera la injini limapangitsa kuti liziyendetsedwe pa liwiro lirilonse ndi poyipitsa kuchepa kwa mkali pamene liwiro likuwonjezeka. Mwamwayi magalimoto oyendetsa kawirikawiri amakhala ndi chigawo chakufa kumene galimoto sizingakhoze kuyendetsa katundu pa liwiro lopatsidwa. Izi ndi chifukwa chotsatira dongosololi ndipo zimasiyanasiyana ndi mankhwala ndi mapangidwe onse.
- Resonance - Stepper motors kayendetsedwe ka mawotchi ndi mawotchi onse akhoza kuvutika ndi resonance. Resonance imachitika pamene maulendo oyendetsa galimoto amayendera mafupipafupi a chikhalidwe ndi mphamvu zomwe zawonjezeka kuntchito zimapangitsa kuwonjezereka kwake ndi kutaya nthawi m'malo mofulumira. M'magwiritsidwe ntchito komwe kuzungulira kwakukulu kudzakhala kovuta, kupeza ndi kudumpha mothamanga ya resonance imayendera kwambiri. Ngakhale mapulogalamu omwe amatha kulekerera kuthamanga ayenera kupeĊµa chivomezi ngati n'kotheka popeza zingathe kuchepetsa moyo wa dongosolo.
- Kukula kwake - Stepper motors ali ndi njira zingapo zoyendetsa galimoto, kuphatikizapo kuyendetsa makina omwe amalola kuti zing'onozing'ono zoposa zonse zogwiritsidwa ntchito ndi magalimoto. Mapulogalamuwa samapereka chidziwitso chowonjezereka (m'malo mochepetsera tizilombo toyambitsa matenda amachepetsedwa molondola) koma amapangitsa magalimoto oyendetsa galimoto kuti agwire ntchito mofulumira. Magetsi othamanga akhoza kuthamangitsidwa mofulumira, ndipo galimotoyo sichiwona mosiyana mu sitepe yaying'ono kapena sitepe yonse. Kuti muyambe kugwira ntchito mofulumira, kuyendetsa galimoto yoyendetsa ndi mapazi onse nthawi zambiri kumafunika. Komabe, kugwiritsa ntchito tizilombo tomwe timadutsa pamakina oyendetsa galimoto kungachepetseko phokoso ndi kugwedeza mu dongosolo.
