Stepper motor mathamangitsidwe ndi deceleration control

Stepper motormfundo yogwirira ntchito
Kawirikawiri, rotor ya injini ndi maginito okhazikika. Pamene mafunde akuyenda mu stator mafunde, ndi stator mapiringidzo amapanga vekitala maginito. Mphamvu ya maginito imeneyi imayendetsa rotor kuti izungulire ndi ngodya kotero kuti njira ya maginito awiri a rotor igwirizane ndi malo a stator. Pamene vekitala ya maginito ya stator imazungulira ndi ngodya.

Stepper motorndi mtundu wa injini yolowera, mfundo yake yogwirira ntchito ndikugwiritsa ntchito magetsi oyendera magetsi, magetsi achindunji kukhala magetsi ogawana nthawi, ma multiphase timing control pano, ndi awa a stepper motor power supply, stepper motor imatha kugwira ntchito bwino, dalaivala ndi ya stepper motor yogawana nthawi, multiphase timing controller.

Kulowetsa kulikonse ndi kugunda kwamagetsi, mota imazungulira ngodya kutsogolo sitepe imodzi. Kusamuka kwake kwa angular kumayenderana ndi kuchuluka kwa ma pulses, liwiro limayenderana ndi pafupipafupi. Sinthani dongosolo la mphamvu zokhotakhota, injiniyo idzasintha. Chifukwa chake mutha kuwongolera kuchuluka kwa ma pulses, ma frequency ndi dongosolo la kupatsa mphamvu gawo lililonse la mafunde amagalimoto kuti muwongolere kuzungulira kwa motor stepper.

Kulondola kwa motor stepper general ndi 3-5% ya ngodya yodutsa, ndipo simadziunjikira.

Ma torque a stepper motor amachepera pomwe liwiro likuwonjezeka. Pamene stepper motor imazungulira, inductance ya gawo lililonse la mafunde agalimoto imapanga mphamvu yamagetsi yosinthira; kumtunda kwa ma frequency, kumapangitsanso mphamvu yamagetsi yakumbuyo. Pansi pakuchita kwake, injini yokhala ndi ma frequency (kapena liwiro) imawonjezeka ndipo gawo lapano limachepa, zomwe zimabweretsa kuchepa kwa torque.

Stepper galimoto akhoza ntchito bwinobwino pa liwiro otsika, koma ngati apamwamba kuposa ena liwiro sangayambe, ndi limodzi ndi mluzu phokoso.

Magalimoto a Stepper ali ndi gawo laumisiri: ma frequency oyambira osanyamula katundu, ndiye kuti, mota ya stepper ikapanda kugunda pafupipafupi imatha kuyambika nthawi zonse, ngati kugunda kwafupipafupi kumakhala kotsika mtengo, mota siyingayambike bwino, imatha kuchitika popanda mayendedwe kapena kutsekereza.

Pankhani ya katundu, mafupipafupi oyambira ayenera kukhala ochepa. Ngati galimoto kuti tikwaniritse kuthamanga kwambiri kasinthasintha, kugunda pafupipafupi kuyenera kukhala ndi njira yothamangitsira, mwachitsanzo, mafupipafupi oyambira ndi otsika, kenako amakwera kufupipafupi komwe amafunidwa (mothamanga kuchokera ku liwilo lotsika kupita ku liwiro lalikulu) pa liwiro linalake.

Chifukwa chiyani?ma stepper motorsziyenera kulamulidwa ndi kuchepetsa liwiro
Kuthamanga kwa mota ya stepper kumadalira pafupipafupi kugunda, kuchuluka kwa mano ozungulira komanso kuchuluka kwa kumenyedwa. Liwiro lake la angular ndilofanana ndi kugunda kwafupipafupi ndipo limagwirizanitsidwa ndi nthawi ndi kugunda. Choncho, ngati chiwerengero cha mano a rotor ndi chiwerengero cha kumenyedwa kothamanga ndizotsimikizika, liwiro lofunidwa lingapezeke poyang'anira kugunda kwafupipafupi. Popeza stepper motor imayambitsidwa mothandizidwa ndi torque yake yolumikizirana, ma frequency oyambira sakhala okwera kuti asataye masitepe. Makamaka pamene mphamvu ikuwonjezeka, kukula kwa rotor kumawonjezeka, inertia imawonjezeka, ndipo mafupipafupi oyambira ndi maulendo othamanga amatha kusiyana ndi nthawi khumi.

The chiyambi pafupipafupi makhalidwe a stepper galimoto kuti stepper galimoto sangathe mwachindunji kufika pafupipafupi ntchito, koma kukhala ndi ndondomeko yoyambira, ndiye kuti, kuchokera pa liwiro otsika pang'onopang'ono zipolopolo mpaka liwiro ntchito. Imani pamene mafupipafupi ogwiritsira ntchito sangathe kugwa mpaka ziro, koma kukhala ndi kuchepetsa kuthamanga kwapang'onopang'ono mpaka ziro.

Chifukwa chake, magwiridwe antchito a stepper motor nthawi zambiri amayenera kudutsa mathamangitsidwe, kuthamanga kwa yunifolomu, kutsika magawo atatu, kuthamangitsa ndi kuthamangitsa njira yayifupi momwe kungathekere, kuthamanga kwanthawi zonse momwe kungathekere. Makamaka mu ntchito yomwe ikufuna kuyankha mwachangu, nthawi yofunikira kuti muthamangire kuyambira poyambira mpaka kumapeto ndi yaifupi kwambiri, yomwe imayenera kutsata njira yaifupi kwambiri yothamangitsira ndi kutsika, komanso kuthamanga kwambiri pa liwiro lokhazikika.

Kuthamanga ndi kutsika kwa algorithm ndi imodzi mwamakina ofunikira pakuwongolera kuyenda, ndi chimodzi mwazinthu zofunika kwambiri kuti mukwaniritse kuthamanga kwambiri komanso kuchita bwino kwambiri. Mu ulamuliro wa mafakitale, kumbali imodzi, ndondomeko yowonongeka imayenera kukhala yosalala komanso yosasunthika, yokhala ndi kusinthasintha kochepa; komano, pamafunika nthawi yoyankha mwachangu komanso kuchitapo kanthu mwachangu. M'malo owonetsetsa kuwongolera kuwongolera kuwongolera magwiridwe antchito, kuti akwaniritse zoyenda zosalala komanso zokhazikika zamakina, ndikusintha kwamakampani komwe kwakhala kuti athetse vuto lalikulu. Ma aligorivimu othamangitsa ndi kutsitsa omwe amagwiritsidwa ntchito kwambiri pamakina owongolera apano amaphatikiza: kuthamanga kwa ma curve a trapezoidal ndi kutsika, kuthamangitsa ma curve ndi kutsika, kuthamangitsa ndi kutsika kwa ma curve owoneka ngati S, kuthamangitsa ma curve ndi kutsika, etc.

Trapezoidal curve mathamangitsidwe ndi deceleration
Tanthauzo: Kuthamanga/kutsika motsatira mzere (kuthamanga/kutsika kuchokera pa liwiro loyambira kufika pa liwiro lomwe mukufuna) ndi chiŵerengero china.

Kuwerengera: v(t)=Vo+at

Ubwino ndi kuipa: Trapezoidal curve imadziwika ndi algorithm yosavuta, yocheperako nthawi, kuyankha mwachangu, kuchita bwino kwambiri komanso kukhazikitsa kosavuta. Komabe, yunifolomu mathamangitsidwe ndi deceleration magawo sizigwirizana ndi stepper galimoto liwiro kusintha lamulo, ndi kusintha mfundo pakati pa liwiro variable ndi liwiro yunifolomu sangakhale yosalala. Chifukwa chake, ma aligorivimuwa amagwiritsidwa ntchito makamaka m'mapulogalamu omwe zofunikira pakuthamangitsa komanso kutsitsa sizili zapamwamba.

Exponential curve mathamangitsidwe ndi kuchepa
Tanthauzo: Kumatanthauza kufulumizitsa ndi kuchepekera mwa ntchito yofotokozera.

Mathamangitsidwe ndi deceleration control evaluation index:
1, Kulondola kwa makina ndi zolakwika zamalo ziyenera kukhala zazing'ono momwe zingathere

2, Makina oyenda ndi osalala, jitter ndi yaying'ono, ndipo kuyankha kuli mwachangu

3, mathamangitsidwe ndi deceleration aligorivimu iyenera kukhala yosavuta momwe ndingathere, yosavuta kugwiritsa ntchito, ndipo imatha kukwaniritsa zofunikira pakuwongolera nthawi yeniyeni.

Ngati mukufuna kulankhulana ndi kugwirizana nafe, chonde omasuka kulankhula nafe.
Timayanjana kwambiri ndi makasitomala athu, kumvetsera zosowa zawo ndikuchita zomwe akufuna. Timakhulupirira kuti mgwirizano wopambana-wopambana umachokera ku khalidwe lazogulitsa ndi ntchito yamakasitomala.

Changzhou Vic-tech Motor Technology Co., Ltd. ndi akatswiri ofufuza ndi kupanga omwe amayang'ana kwambiri kafukufuku wamagalimoto ndi chitukuko, mayankho onse ogwiritsira ntchito magalimoto, kukonza ndi kupanga zinthu zamagalimoto. Ltd. yakhala yapadera popanga ma motors ang'onoang'ono ndi zowonjezera kuyambira 2011. Zogulitsa zathu zazikulu: ma motors ang'onoang'ono a stepper, ma gear motors, ma motors geared, ma thrusters apansi pamadzi ndi madalaivala ndi owongolera.

Gulu lathu lili ndi zaka zopitilira 20 pakupanga, kupanga ndi kupanga ma injini ang'onoang'ono, ndipo amatha kupanga zinthu ndikuthandizira makasitomala opanga malinga ndi zosowa zapadera! Pakali pano, ife makamaka kugulitsa kwa makasitomala m'mayiko mazana Asia, North America ndi Europe, monga USA, UK, Korea, Germany, Canada, Spain, etc. wathu "umphumphu ndi kudalirika, khalidwe lokhazikika" nzeru zabizinesi, "makasitomala choyamba" mtengo zikhalidwe kulengeza luso lochokera ntchito, mgwirizano, imayenera mzimu wa ogwira ntchito zamakampani, kugawana nawo "Makasitomala".
