Kuyerekeza ubwino ndi kuipa kwa njira 5 zoyendetsera ma stepper motors

Kukula kwa ukadaulo wa stepper motor drive, luso lililonse laukadaulo lidzabweretsa kusintha kwakukulu pamsika ndi ukadaulo wapamwamba kuti utsogolere msika.

1. Kuyendetsa magetsi nthawi zonse

Kuyendetsa kwamagetsi amodzi kumatanthauza njira yogwirira ntchito yozungulira injini, magetsi owongolera amodzi okha pamagetsi ozungulira, ma winding angapo amapereka magetsi mosinthana. Njirayi ndi yakale kwambiri yoyendetsera, tsopano simugwiritsa ntchito kwenikweni.

Ubwino: derali ndi losavuta, zigawo zochepa, kulamulira kulinso kosavuta, kuzindikira kwake n'kosavuta.

Zoyipa: iyenera kupereka transistor yayikulu yokwanira kuti isinthe makina, liwiro loyendetsa injini ya stepper ndi lochepa, kugwedezeka kwa injini ndi kwakukulu, kutentha. Popeza sikugwiritsidwanso ntchito, sikufotokozedwa zambiri.

2. Kuyendetsa kwamagetsi okwera komanso otsika

Chifukwa cha kuyendetsa magetsi nthawi zonse pali zofooka zambiri, kupita patsogolo kwa ukadaulo, chitukuko cha kuyendetsa magetsi atsopano okwera komanso otsika kuti akonze zolakwika zina za kuyendetsa magetsi nthawi zonse, mfundo ya kuyendetsa magetsi okwera komanso otsika ndi, mu kayendedwe ka injini mpaka sitepe yonse pamene kugwiritsa ntchito mphamvu yowongolera magetsi okwera, mu kayendedwe ka theka-sitepe pamene kugwiritsa ntchito mphamvu yowongolera magetsi otsika, kuyimitsa ndi kugwiritsa ntchito mphamvu yotsika kuti muwongolere.

Ubwino: kuwongolera kwa magetsi okwera komanso otsika kumawongolera kugwedezeka ndi phokoso mpaka pamlingo winawake, ndipo lingaliro la mota yoyendetsa magalimoto ogawa magawo laperekedwa koyamba, ndipo njira yogwirira ntchito yochepetsera mphamvu yamagetsi pakati ikayima ikuperekedwanso.

Zoyipa: derali ndi lovuta poyerekeza ndi kuyendetsa kwamagetsi kosalekeza, makhalidwe apamwamba a zofunikira za transistor, mota ikadali kugwedezeka kwakukulu pa liwiro lotsika, kutentha kukadali kwakukulu, ndipo tsopano kwenikweni musagwiritse ntchito njira iyi yoyendetsera.

3. Chojambulira chokhazikika chodzisangalatsa chokha

Chopper drive yodzilimbitsa yokha imagwira ntchito kudzera mu kapangidwe ka hardware pamene current ifika pamtengo winawake pamene current kudzera mu hardware idzatsekedwa, kenako n’kusinthidwa kukhala current ina yozungulira, current ina yozungulira kukhala current yokhazikika, kenako kudzera mu hardware idzatsekedwa, ndi zina zotero, kuti ipititse patsogolo ntchito ya stepper motor.

Ubwino: phokoso limachepa kwambiri, liwiro limawonjezeka kufika pamlingo winawake, magwiridwe antchito kuposa mitundu iwiri yoyambirira ya kusintha kwina.

Zoyipa: zofunikira pakupanga ma circuit ndi zapamwamba, zofunikira pakulimbana ndi kusokoneza ma circuit ndi zapamwamba, zosavuta kuyambitsa ma frequency ambiri, zigawo za drive zoyaka, zofunikira pakugwira ntchito kwa zigawo ndi zapamwamba.

4. Chojambulira choyerekeza chamakono (pakali pano ndi ukadaulo waukulu womwe umagwiritsidwa ntchito pamsika)

Chojambulira choyerekeza chamakono ndi mtengo wamakono wa stepper motor womwe umalowa mu gawo linalake la voteji, ndipo mtengo woyambira wa D / A converter woyerekeza ndi mtengo woyambira, womwe umatengera kufananiza kwa chosinthira champhamvu, kuti akwaniritse cholinga chowongolera mphamvu yamagetsi.

Ubwino: kuti chowongolera mayendedwe chizitsanzira makhalidwe a sine wave, zomwe zimapangitsa kuti magwiridwe antchito aziyenda bwino kwambiri, liwiro la mayendedwe ndi phokoso ndizochepa, mutha kugwiritsa ntchito gawo lalikulu, ndiyo njira yotchuka yowongolera pakadali pano.

Zoyipa: dera ndi lovuta kwambiri, kusokoneza kwa dera kumakhala kovuta kulamulira ndikugwirizana ndi zofunikira za chiphunzitso, kosavuta kupanga jitter, pakulamulira mapangidwe a nsonga za sinusoidal ndi zigwa, zomwe zingayambitse kusokoneza kwa ma frequency apamwamba, zomwe zimapangitsa kuti kutentha kwa zigawo zoyendetsera kapena chifukwa cha ukalamba wa ma frequency ndi okwera kwambiri, chomwe ndi chifukwa chachikulu chomwe madalaivala ambiri ndi osavuta kugwiritsa ntchito kwa zaka zoposa 1 chifukwa cha zifukwa zazikulu za kuwala kofiira koteteza.

5. Choyendetsa choviikidwa m'madzi

Uwu ndi ukadaulo watsopano wowongolera mayendedwe, ukadaulowu uli mu kuyerekeza kwamakono kwa ukadaulo wa chopper drive, pansi pa mfundo yothana ndi zofooka ndi zatsopano za njira yatsopano yoyendetsera. Ukadaulo wake waukulu uli mu kuyerekeza kwamakono kwa chopper drive pansi pa mfundo yowonjezera kutentha kwa chinthu choyendetsera ndi ukadaulo woteteza ma frequency ambiri.

Ubwino: ubwino wa chopper drive yoyerekeza, kutentha kwake ndi kochepa kwambiri, ndipo nthawi yayitali yogwira ntchito.

Zoyipa: ukadaulo watsopano, mtengo wake ndi wokwera, zofunikira zonse zokhudzana ndi injini yokwera ndi dalaivala ndizokhwima kwambiri.
