Mu ntchito yachibadwa, ndistepper motaimasuntha ngodya imodzi, mwachitsanzo, sitepe imodzi kutsogolo, pamtundu uliwonse wa kugunda komwe kumalandira. Ngati mphamvu zowongolera zikulowetsedwa mosalekeza, mota imazungulira mosalekeza molingana. Kutuluka motere kumaphatikizapo sitepe yotayika komanso kuwoloka. Pamene sitepe yatayika, chiwerengero cha masitepe omwe amapita patsogolo ndi rotor ndi ocheperapo chiwerengero cha pulses; pamene sitepe yadutsa, chiwerengero cha masitepe opita patsogolo ndi rotor ndi ochuluka kuposa chiwerengero cha pulses. Nambala ya masitepe a sitepe imodzi yotayika ndi kupitirira ndi yofanana ndi kuchuluka kwa chiwerengero cha ma beats othamanga. Kutayika kwakukulu kumapangitsa kuti rotor ikhale pamalo amodzi kapena kugwedezeka mozungulira malo amodzi, ndipo kupitirira kwakukulu kumapangitsa kuti galimotoyo idutse.
Kutayika kwa sitepe ndi njira
(1) Mathamangitsidwe a rotor ndi pang'onopang'ono kuposa mozungulira maginito maginitostepper mota
Kufotokozera:
Pamene mathamangitsidwe a rotor ndi pang'onopang'ono kuposa kasinthasintha maginito wa stepper galimoto, mwachitsanzo, m'munsi kuposa gawo kusintha liwiro, ndi stepper galimoto amapanga kunja-sitepe. Izi ndichifukwa chakuchepa mphamvu athandizira kwa galimoto ndi makokedwe synchronizing kwaiye mu stepper galimoto salola wozungulira liwiro kutsatira rotational liwiro la stator maginito munda, motero kuchititsa kunja-sitepe. Popeza mphamvu yotulutsa ma torque ya stepper motor imachepa pomwe kuchuluka kwa magwiridwe antchito kumakwera, ma frequency aliwonse ogwiritsira ntchito kuposa pamenepo amatulutsa sitepe yotayika. Kutayika uku kukuwonetsa kuti stepper motor ilibe torque yokwanira komanso ilibe mphamvu yokoka yokwanira.
Yankho:
a. Pangani ma torque a electromagnetic opangidwa ndi makwerero okwera omwe achuluke. Izi zitha kukhala mumayendedwe ovotera kuti muwonjezere kuyendetsa; m'makokedwe apamwamba kwambiri sikokwanira, mutha kusintha voteji yoyendetsa galimoto; sinthani kuti mugwiritse ntchito cholumikizira chachikulu cha torque, ndi zina zambiri. Izi zitha kuchitika mwa kuchepetsa moyenerera ma frequency ogwiritsira ntchito mota kuti muwonjezere ma torque agalimoto; kukhazikitsa nthawi yowonjezereka yowonjezereka kuti rotor ipeze mphamvu zokwanira.
(2) Kuthamanga kwapakati kwa rotor ndikwapamwamba kuposa kuthamanga kwapakati pa stator magnetic field
Kufotokozera:
Kuthamanga kwapakati kwa rotor ndikwambiri kuposa liwiro lozungulira la maginito a stator, pomwe stator imalimbikitsidwa komanso kusangalatsidwa kwa nthawi yayitali kuposa nthawi yofunikira kuti rotor ipite patsogolo, ndiye kuti rotor imapeza mphamvu zochulukirapo podutsa, zomwe zimapangitsa kuti torque yotulutsa yomwe imapangidwa ndi makwerero akukwera, ndikupangitsa kuti mota idutse. Pamene makwerero amoto amagwiritsidwa ntchito poyendetsa njira zomwe zimapangitsa kuti katundu aziyenda mmwamba ndi pansi, amatha kupanga chodabwitsa cha kupitirira, chifukwa chakuti torque yomwe imafunidwa ndi galimotoyo imachepa pamene katundu akutsika.
Yankho:
Chepetsani ma drive apano amotor poponda kuti muchepetse torque ya ma steping motor.
(3) Inertia yamoterendi katundu wake
Kufotokozera:
Chifukwa cha inertia ya motor stepping motor yokha ndi katundu omwe amanyamula, galimotoyo siyingayambitsidwe ndikuyimitsidwa nthawi yomweyo pakugwira ntchito, koma sitepe yotayika imachitika poyambira ndipo kupitilira apo kuyimitsa.
Yankho:
Kudzera mathamangitsidwe ndi deceleration ndondomeko, mwachitsanzo, kuyambira pa liwiro m'munsi, ndiye pang'onopang'ono imathandizira kuti ena liwiro ntchito, ndiyeno pang'onopang'ono decelerating mpaka kuima. Kuthamangitsa koyenera komanso kosalala ndi kuwongolera kwapang'onopang'ono ndiye chinsinsi chotsimikizira kudalirika, kothandiza komanso kolondola kwa kayendetsedwe ka stepper drive.
(4) Kumveka kwa injini yoyenda
Kufotokozera:
Resonance imakhalanso chifukwa cha kunja. Pamene stepper motor ikugwira ntchito mosalekeza, ngati ma frequency a control pulse ali ofanana ndi ma frequency amtundu wa stepper motor, resonance idzachitika. Mkati mwa nthawi imodzi yowongolera kugunda, kugwedezeka sikumachepetsedwa mokwanira, ndipo kugunda kotsatira kumabwera, motero cholakwika champhamvu pafupi ndi ma frequency a resonance ndicho chachikulu kwambiri ndipo chimapangitsa kuti stepper motor itaye sitepe.
Yankho:
Moyenera kuchepetsa kuyendetsa panopa kwa stepper motor; gwiritsani ntchito njira yogawa magawo; gwiritsani ntchito njira zonyowetsa, kuphatikizapo njira yochepetsera makina. Njira zonse zomwe zili pamwambazi zimatha kuthetsa kugwedezeka kwa injini ndikupewa zochitika zakunja.
(5) Kutaya mphamvu pamene ukusintha njira
Kufotokozera:
Zimasonyezedwa kuti n’zolondola kumbali iliyonse, koma zimaunjikana kupatuka mwamsanga pamene njirayo yasinthidwa, ndipo nthaŵi zambiri ikasinthidwa, m’pamenenso imapatuka.
Yankho:
General stepper pagalimoto pa malangizo ndi kugunda zizindikiro ndi zofunika zina, monga: malangizo a chizindikiro mu kugunda koyamba pamodzi kukwera m'mphepete kapena kugwa m'mphepete (zofunika osiyana pagalimoto si ofanana) pamaso pa kufika kwa microseconds ochepa kutsimikiza, apo ayi padzakhala kugunda kwa ngodya ya opareshoni ndi kufunika kwenikweni kutembenukira ku mbali ina, ndipo potsirizira pake ndi kulephera kwazing'ono. kuwonongeka kumawonekera kwambiri, yankho limagwiritsidwa ntchito makamaka mu mapulogalamu kuti asinthe malingaliro a kutumiza phokoso Njira yothetsera vutoli makamaka kugwiritsa ntchito mapulogalamu kuti asinthe malingaliro otumizira ma pulses kapena kuwonjezera kuchedwa.
(6) Zowonongeka zamapulogalamu
Kufotokozera:
Njira zowongolera zimatsogolera ku sitepe yotayika si zachilendo, muyenera kuyang'ana pulogalamu yolamulira si vuto.
Yankho:
Sindikupeza chomwe chayambitsa vutoli kwakanthawi, palinso mainjiniya omwe amalola kuti stepper motor iziyenda kwakanthawi kuti apezenso komwe adachokera.
