Kuthamanga kwa injini ya stepper ndi kuwongolera kuchepa kwa mphamvu

Galimoto yoyendera masitepemfundo yogwirira ntchito
Kawirikawiri, rotor ya mota ndi maginito okhazikika. Pamene mphamvu ikuyenda kudzera mu stator winding, stator winding imapanga vector magnetic field. Magnetic field iyi imayendetsa rotor kuti izungulire ndi ngodya kotero kuti njira ya maginito awiri a rotor igwirizane ndi ya stator's field. Pamene vector magnetic field ya stator izungulire ndi ngodya.

Galimoto yoyendera masitepeNdi mtundu wa injini yolowetsa magetsi, mfundo yake yogwirira ntchito ndi kugwiritsa ntchito magetsi amagetsi, magetsi olunjika kupita ku magetsi ogawana nthawi, magetsi owongolera nthawi ambiri, ndi magetsi awa amagetsi a injini yoyenda, injini yoyenda imatha kugwira ntchito bwino, dalaivala ndi magetsi ogawana nthawi a injini yoyenda, komanso chowongolera nthawi cha magawo ambiri.

Cholowetsa chilichonse chikalowa mu pulse yamagetsi, mota imazungulira ngodya patsogolo sitepe imodzi. Kusuntha kwake kwa angular komwe kumatulutsa kumagwirizana ndi kuchuluka kwa ma pulse omwe amalowa, liwiro limagwirizana ndi kuchuluka kwa ma pulse. Sinthani dongosolo la mphamvu yozungulira, mota idzabwerera m'mbuyo. Chifukwa chake mutha kuwongolera kuchuluka kwa ma pulse, ma frequency ndi dongosolo la mphamvu yolimbitsa gawo lililonse la mota kuti muwongolere kuzungulira kwa mota yoyenda.

Kulondola kwa mota ya stepper ndi 3-5% ya ngodya yolowera, ndipo sikusonkhanitsidwa.

Mphamvu ya mota ya stepper idzachepa pamene liwiro likuwonjezeka. Pamene mota ya stepper ikuzungulira, mphamvu ya gawo lililonse la kuzunguliza kwa mota imapanga mphamvu yamagetsi yobwerera; kuchuluka kwa ma frequency, mphamvu yamagetsi yobwerera imakhala yayikulu. Pansi pa ntchito yake, mota yokhala ndi ma frequency (kapena liwiro) imawonjezeka ndipo mphamvu yamagetsi imachepa, zomwe zimapangitsa kuti mphamvu yamagetsi ichepe.

Galimoto ya stepper imatha kugwira ntchito bwino pa liwiro lotsika, koma ngati ili pamwamba kuposa liwiro linalake, sidzayamba, ndipo imabwera ndi phokoso la mluzu.

Mota ya stepper ili ndi parameter yaukadaulo: ma frequency oyambira osanyamula katundu, ndiko kuti, mota ya stepper ngati ma frequency osanyamula katundu amatha kuyambika bwino, ngati ma frequency a pulse ndi apamwamba kuposa mtengo, mota singayambe bwino, ikhoza kuchitika pa sitepe kapena kutsekeka.

Pankhani ya katundu, ma frequency oyambira ayenera kukhala otsika. Ngati mota ikufuna kuzungulira mwachangu, ma frequency oyambira ayenera kukhala ndi njira yofulumira, mwachitsanzo, ma frequency oyambira ndi otsika, kenako amakwera kufika pa ma frequency apamwamba omwe mukufuna (liwiro la mota kuchokera pa liwiro lotsika kupita pa liwiro lalikulu) pa liwiro linalake.

Chifukwa chiyanimota zoyendera masitepeziyenera kulamulidwa ndi kuchepetsa liwiro
Liwiro la mota yoyendera limadalira kuchuluka kwa kugunda kwa mtima, kuchuluka kwa mano ozungulira komanso kuchuluka kwa ma beats. Liwiro lake la angular limagwirizana ndi kuchuluka kwa kugunda kwa mtima ndipo limagwirizanitsidwa ndi nthawi ya kugunda kwa mtima. Chifukwa chake, ngati kuchuluka kwa mano ozungulira ndi kuchuluka kwa ma beats othamanga kuli kotsimikizika, liwiro lomwe mukufuna lingapezeke powongolera kuchuluka kwa kugunda kwa mtima. Popeza mota yoyendera imayatsidwa ndi torque yake yolumikizana, kuchuluka koyambira sikokwera kwambiri kuti musataye sitepe. Makamaka pamene mphamvu ikuwonjezeka, kukula kwa rotator kumawonjezeka, inertia imawonjezeka, ndipo kuchuluka koyambira ndi kuchuluka kothamanga kwakukulu kumatha kusiyana ndi nthawi khumi.

Makhalidwe a pafupipafupi oyambira a mota ya stepper kuti injini ya stepper iyambe sangafikire mwachindunji pafupipafupi yogwirira ntchito, koma kuti ikhale ndi njira yoyambira, ndiko kuti, kuchokera pa liwiro lotsika pang'onopang'ono ikwere mpaka liwiro logwirira ntchito. Imani pamene pafupipafupi yogwirira ntchito singatsike nthawi yomweyo kufika pa zero, koma kuti ikhale ndi kuchepetsa pang'onopang'ono liwiro mpaka pa zero.

Chifukwa chake, ntchito ya mota ya stepper nthawi zambiri imayenera kudutsa mu kuthamanga, liwiro lofanana, kutsika kwa liwiro magawo atatu, njira yofulumira ndi kutsika kwa liwiro ifupi momwe ingathere, nthawi yothamanga nthawi zonse itali momwe ingathere. Makamaka pantchito yomwe imafuna kuyankha mwachangu, nthawi yofunikira kuyambira poyambira mpaka kumapeto ndiyo yochepa kwambiri, yomwe iyenera kufunikira njira yaifupi kwambiri yothamanga ndi kutsika kwa liwiro, komanso liwiro lapamwamba kwambiri pa liwiro losasintha.

Njira yofulumizitsa ndi kuchepetsa liwiro ndi imodzi mwa njira zofunika kwambiri pakulamulira kayendedwe ka zinthu, ndipo ndi imodzi mwa zinthu zofunika kwambiri kuti munthu azitha kuthamanga kwambiri komanso kugwira ntchito bwino. Mu kayendetsedwe ka mafakitale, mbali imodzi, njira yoyendetsera zinthu imafunika kukhala yosalala komanso yokhazikika, yokhala ndi mphamvu yochepa yosinthasintha; kumbali ina, imafuna nthawi yoyankha mwachangu komanso kuchitapo kanthu mwachangu. Pofuna kuonetsetsa kuti kayendetsedwe ka zinthu kakulondola kuti zinthu ziyende bwino, kuti makina aziyenda bwino komanso mokhazikika, njira yoyendetsera zinthu m'mafakitale yakhala ikuthetsa vuto lalikulu. Njira zofulumizitsa ndi kuchepetsa liwiro zomwe zimagwiritsidwa ntchito kwambiri m'makina oyendetsera zinthu amakono ndi monga: kuthamanga ndi kuchepetsa liwiro la trapezoidal curve, kuthamanga ndi kuchepetsa liwiro la exponential curve, kuthamanga ndi kuchepetsa liwiro la S-shaped curve, kuthamanga ndi kuchepetsa liwiro la parabolic curve, ndi zina zotero.

Kuthamanga ndi kutsika kwa ma curve a trapezoidal
Tanthauzo: Kuthamanga/kuchepa kwa liwiro mwanjira yolunjika (kuthamanga/kuchepa kwa liwiro kuchokera pa liwiro loyambira kupita ku liwiro lolunjika) ndi chiŵerengero china

Fomula yowerengera: v(t)=Vo+at

Ubwino ndi kuipa: Mzere wa trapezoidal umadziwika ndi njira yosavuta, yosatenga nthawi yambiri, yankho lachangu, yogwira ntchito bwino komanso yosavuta kuyigwiritsa ntchito. Komabe, magawo ofanana a kuthamanga ndi kutsika kwa liwiro sakugwirizana ndi lamulo losintha liwiro la mota ya stepper, ndipo malo osinthira pakati pa liwiro losinthasintha ndi liwiro lofanana sangakhale osalala. Chifukwa chake, njira iyi imagwiritsidwa ntchito makamaka m'mapulogalamu omwe zofunikira pakuthamanga ndi kutsika kwa liwiro sizili zapamwamba.

Kuthamanga ndi kutsika kwa ma curve a Exponential
Tanthauzo: Limatanthauza kufulumira ndi kuchepetsa liwiro pogwiritsa ntchito ntchito yowonetsera.

Kuthamanga ndi kuchepetsa mphamvu ya ulamuliro kuwunika index:
1, Cholakwika cha njira ya makina ndi malo chiyenera kukhala chochepa momwe zingathere

2, Kuyenda kwa makina kumakhala kosalala, kugwedezeka kumakhala kochepa, ndipo yankho lake ndi lachangu

3, njira yofulumira komanso yochepetsera liwiro iyenera kukhala yosavuta momwe ingathere, yosavuta kuyigwiritsa ntchito, komanso yokwaniritsa zofunikira zowongolera nthawi yeniyeni

Ngati mukufuna kulankhulana ndi kugwirizana nafe, chonde musazengereze kulankhula nafe.
Timagwirizana kwambiri ndi makasitomala athu, timamvetsera zosowa zawo ndikuchita zomwe akufuna. Timakhulupirira kuti mgwirizano pakati pa onse umadalira khalidwe la malonda ndi utumiki kwa makasitomala.

Changzhou Vic-tech Motor Technology Co., Ltd. ndi bungwe la akatswiri ofufuza ndi kupanga lomwe limayang'ana kwambiri kafukufuku ndi chitukuko cha magalimoto, mayankho onse a ntchito zamagalimoto, ndi kukonza ndi kupanga zinthu zamagalimoto. Ltd. yakhala yapadera pakupanga ma mota ang'onoang'ono ndi zowonjezera kuyambira 2011. Zogulitsa zathu zazikulu: ma mota ang'onoang'ono oyendera, ma mota a giya, ma mota a gear, ma thruster oyenda pansi pa madzi ndi ma driver a magalimoto ndi owongolera magalimoto.

Gulu lathu lili ndi zaka zoposa 20 zokumana nazo popanga, kupanga ndi kupanga ma micro-motor, ndipo limatha kupanga zinthu ndikuthandizira makasitomala opanga malinga ndi zosowa zapadera! Pakadali pano, timagulitsa makamaka kwa makasitomala m'maiko mazana ambiri ku Asia, North America ndi Europe, monga USA, UK, Korea, Germany, Canada, Spain, ndi zina zotero. Malingaliro athu a bizinesi "okhulupirika ndi odalirika, oganizira bwino", miyezo ya "kasitomala patsogolo" imalimbikitsa luso lochita zinthu zatsopano, mgwirizano, mzimu wogwira mtima wa bizinesi, kukhazikitsa "kumanga ndi kugawana". Cholinga chachikulu ndikupanga phindu lalikulu kwa makasitomala athu.
