Zifukwa ndi njira zothetsera vuto la injini ya stepper

Pakugwira ntchito bwino,mota ya stepperImasuntha ngodya imodzi ya sitepe, mwachitsanzo sitepe imodzi patsogolo, pa kugunda kulikonse kolamulira komwe kwalandiridwa. Ngati ma pulse owongolera alowetsedwa mosalekeza, mota imazungulira mosalekeza moyenerera. Kutsika kwa mota kuchokera pa sitepe kumaphatikizapo sitepe yotayika ndi yopitirira. Sitepe ikatayika, chiwerengero cha masitepe opititsidwa ndi rotor chimakhala chocheperapo kuposa chiwerengero cha ma pulse; sitepe ikawoloka, chiwerengero cha masitepe opititsidwa ndi rotor chimakhala chochulukirapo kuposa chiwerengero cha ma pulse. Chiwerengero cha masitepe a sitepe imodzi yotayika ndi yopitirira ndi chofanana ndi chiwerengero cha ma beats othamanga. Kutayika kwakukulu kwa sitepe kudzapangitsa rotor kukhala pamalo amodzi kapena kugwedezeka mozungulira malo amodzi, ndipo kupitirira kwambiri kwa sitepe kudzapangitsa kuti mota ipitirire.

Kutayika kwa chifukwa ndi njira

(1) Kuthamanga kwa rotor kumakhala kochedwa kuposa mphamvu ya maginito yozungulira yamota ya stepper

Kufotokozera:

Pamene liwiro la rotor likuyenda pang'onopang'ono kuposa mphamvu yozungulira ya stepper motor, mwachitsanzo, yotsika kuposa liwiro losintha gawo, stepper motor imapanga zinthu zosafunikira. Izi zimachitika chifukwa cha mphamvu yokwanira yolowera ku mota ndipo mphamvu yolumikizirana yomwe imapangidwa mu stepper motor siyilola liwiro la rotor kutsatira liwiro lozungulira la stator magnetic field, zomwe zimapangitsa kuti zinthu zisamayende bwino. Popeza mphamvu yotulutsa mphamvu ya stepper motor imachepa pamene kuchuluka kwa ntchito yopitilira ikukwera, kuchuluka kulikonse kogwira ntchito kuposa pamenepo kudzapanga sitepe yotayika. Kutayika kwa sitepe kumeneku kumasonyeza kuti stepper motor ilibe mphamvu yokwanira ndipo ilibe mphamvu yokwanira yokoka.

Yankho:

a. Pangani mphamvu yamagetsi yopangidwa ndi mota yoponda yokha ikule. Izi zitha kukhala mumtundu wamagetsi woyesedwa kuti muwonjezere mphamvu yoyendetsa; mumtundu wamagetsi woponda kwambiri sikokwanira, mutha kusintha mphamvu yoyendetsa ya dera loyendetsa; sinthani kugwiritsa ntchito mota yoponda yayikulu, ndi zina zotero. b, kuti mota yoponda ikufunika kugonjetsa mphamvu yamagetsi ichepe. Izi zitha kuchitika pochepetsa moyenera mphamvu yogwirira ntchito ya mota kuti muwonjezere mphamvu yotulutsa ya mota; kukhazikitsa nthawi yayitali yothamanga kuti rotor ipeze mphamvu zokwanira.

(2) Liwiro lapakati la rotor ndi lalikulu kuposa liwiro lapakati la kuzungulira kwa stator magnetic field

Kufotokozera:

Liwiro lapakati la rotor ndi lalikulu kuposa liwiro lapakati la mphamvu ya maginito ya stator, pamene stator imapatsidwa mphamvu ndikusangalala kwa nthawi yayitali kuposa nthawi yomwe imafunika kuti rotor ipite patsogolo, ndiye kuti rotor imapeza mphamvu zambiri panthawi yoponda, zomwe zimapangitsa kuti mphamvu yotulutsa yopangidwa ndi mota yoponda iwonjezereke, zomwe zimapangitsa kuti mota ipitirire. Pamene mota yoponda imagwiritsidwa ntchito kuyendetsa njira zomwe zimapangitsa kuti katundu ayende mmwamba ndi pansi, zimakhala zosavuta kupanga vuto la kuponda mopitirira muyeso, zomwe zimachitika chifukwa chakuti mphamvu yomwe injini imafuna imachepa pamene katundu akupita pansi.

Yankho:

Chepetsani mphamvu yoyendetsera galimoto ya stepping motor kuti muchepetse mphamvu yotulutsa ya stepping motor.

(3) Kusakhazikika kwamota yopondapondi katundu amene imanyamula

Kufotokozera:

Chifukwa cha kufooka kwa mota yokwerera komanso katundu womwe imanyamula, motayo singathe kuyatsidwa ndikuyimitsidwa nthawi yomweyo ikagwira ntchito, koma sitepe yotayika imachitika poyambira ndipo sitepe yopitilira imachitika poyimitsa.

Yankho:

Kudzera mu njira yofulumizitsa ndi kuchepetsa liwiro, mwachitsanzo kuyambira pa liwiro lotsika, kenako pang'onopang'ono kufulumizitsa liwiro linalake, kenako kufulumizitsa pang'onopang'ono mpaka kuyima. Kufulumizitsa bwino komanso kosalala ndi kuwongolera kuchepetsa liwiro ndiye chinsinsi chotsimikizira kuti makina oyendetsa ma stepper akuyenda bwino, moyenera komanso molondola.

(4) Kumveka bwino kwa mota yokwerera

Kufotokozera:

Kusinthasintha kwa mphamvu (resonance) ndi chifukwa cha kusokonezeka kwa mphamvu. Pamene mota ya stepper ikugwira ntchito mosalekeza, ngati kuchuluka kwa mphamvu ya pulse yowongolera kuli kofanana ndi kuchuluka kwa mphamvu ya injini ya stepper, kusinthasintha kwa mphamvu kudzachitika. Mkati mwa nthawi imodzi ya mphamvu ya pulse yowongolera, kugwedezeka sikuchepa mokwanira, ndipo pulse yotsatira imabwera, motero cholakwika cha mphamvu pafupi ndi mphamvu ya frequency ya resonance ndi chachikulu kwambiri ndipo chidzapangitsa mota ya stepper kutaya sitepe.

Yankho:

Chepetsani mphamvu yoyendetsera galimoto ya stepper moyenerera; gwiritsani ntchito njira yoyendetsera yogawa magawo; gwiritsani ntchito njira zochepetsera kutentha, kuphatikizapo njira yochepetsera kutentha kwa makina. Njira zonse zomwe zili pamwambapa zitha kuthetsa bwino kugwedezeka kwa galimoto ndikupewa vuto la kusokonekera kwa magetsi.

(5) Kutaya mtima pamene mukusintha njira

Kufotokozera:

Zawonetsedwa kuti ndi zolondola mbali iliyonse, koma zimasonkhanitsa kupotoka kumene njirayo ikasinthidwa, ndipo nthawi zambiri ikasinthidwa, imapotoka kwambiri.

Yankho:

Kuyendetsa kwa stepper komwe kumayendetsedwa ndi zizindikiro za pulse kumakhala ndi zofunikira zina, monga: njira ya chizindikiro mu pulse yoyamba yomwe imayendetsedwa ndi m'mphepete wokwera kapena m'mphepete wogwa (zofunikira zosiyanasiyana zoyendetsera sizili zofanana) musanafike ma microseconds angapo kuti adziwike, apo ayi padzakhala kugunda kwa ngodya ya ntchito ndi kufunika kwenikweni kotembenukira kumbali ina, ndipo pamapeto pake vuto la kulephera limawonekera pamene mukupita mopanda tsankho, kuchepa kwa kusweka kumakhala koonekera kwambiri, yankho limagwiritsidwa ntchito makamaka mu pulogalamuyo kusintha malingaliro otumizira pulse. Yankho lake ndikugwiritsa ntchito mapulogalamu kusintha malingaliro otumizira pulse kapena kuwonjezera kuchedwa.

(6) Zolakwika za pulogalamu

Kufotokozera:

Njira zowongolera zomwe zimatsogolera ku sitepe yotayika sizachilendo, ndikofunikira kuyang'ana pulogalamu yowongolera si vuto.

Yankho:

Sindingathe kupeza chomwe chayambitsa vutoli kwa kanthawi, palinso mainjiniya omwe amalola injini ya stepper kuti izigwira ntchito kwa kanthawi kuti apezenso komwe idachokera.
