Kodi ma stepper motors amatsika bwanji?

Monga actuator,stepper motandi imodzi mwazinthu zofunika kwambiri zamakina, zomwe zimagwiritsidwa ntchito kwambiri pamakina osiyanasiyana owongolera makina. Pakukula kwaukadaulo waukadaulo wa ma microelectronics ndi kulondola, kufunikira kwa ma stepper motors kukuchulukirachulukira tsiku ndi tsiku, ndipo ma stepper motors ndi makina otumizira magiya amaphatikizidwa mu bokosi la giya lochepetsera, komanso muzochitika zochulukirachulukira zowonera, masiku ano ang'onoang'ono komanso aliyense palimodzi kuti amvetsetse mtundu uwu wa njira yochepetsera magiya.

 

Kodi ma stepper motors amatsika bwanji?

Stepper motor monga yogwiritsidwa ntchito kwambiri, yomwe imagwiritsidwa ntchito kwambiri pagalimoto, yomwe nthawi zambiri imagwiritsidwa ntchito ndi zida za deceleration kuti ikwaniritse njira yabwino yotumizira; ndi stepper motor yomwe imagwiritsidwa ntchito kwambiri zida ndi njira zochepetsera, monga bokosi la giya, encoder, controller, pulse sign, etc..

 

Kutsika kwa pulse:liwiro lozungulira la stepper motor, zimatengera kusintha kwa siginecha yolowera kuti isinthe. Mwachidziwitso, perekani dalaivala kugunda, stepper motor imazungulira masitepe (kugawanika kwa gawo logawanika). Mchitidwe, ngati zimachitika chizindikiro kusintha mofulumira kwambiri, ndi stepper galimoto chifukwa cha mkati damping tingati n'zosiyana mphamvu magetsi, ndi maginito poyankha pakati ozungulira ndi stator sangatsatire kusintha kwa chizindikiro magetsi, zidzachititsa kutsekereza ndi anataya masitepe.

 

Kuchepetsa kuchepa kwa gearbox:stepper motor yokhala ndi gearbox yochepetsera yomwe imagwiritsidwa ntchito palimodzi, kuthamanga kwa ma stepper motor, kuthamanga kwa torque yotsika, yolumikizidwa ndi bokosi la gearbox, gearbox yamkati yochepetsera ma meshing transmission yopangidwa ndi chiŵerengero chochepetsera, kuthamanga kwa mota kutsika kuchepetsedwa, ndikukulitsa torque yotumizira kuti ikwaniritse bwino kufalikira; kuchepetsa kutsika kumadalira kuchuluka kwa ma gearbox, kuchuluka kwa kuchepetsa, kuchepa kwa liwiro lotulutsa, ndi mosemphanitsa. Ndipo mosemphanitsa.

 

Kuthamanga kwa Curve exponential control:exponential curve, mu pulogalamu yamapulogalamu, zoyambira zowerengera nthawi zosungidwa mu kukumbukira kwamakompyuta, zimaloza kusankha pogwira ntchito. Nthawi zambiri, akamaliza stepper galimoto mathamangitsidwe ndi deceleration nthawi 300ms kapena kuposa. Ngati mumagwiritsa ntchito mathamangitsidwe ochepa kwambiri komanso nthawi yochepetsera, chifukwa cha ma motors ambiri otsika, zimakhala zovuta kuti mukwaniritse kusinthasintha kothamanga kwa ma stepper motors.

 

Encoder control deceleration:Kuwongolera kwa PID ngati njira yosavuta komanso yothandiza yowongolera, mu stepper motor drive yapeza ntchito yayikulu. Zimachokera ku mtengo woperekedwa r ( t ) ndi mtengo weniweni wotuluka c ( t ) kuti apange kupotoka kolamulira e ( t ), kupatukana kwa chiwerengero, chophatikizika ndi chosiyana kupyolera mu kuphatikizika kwa mzere wa kuchuluka kwa kulamulira, kulamulira kwa chinthu cholamulira. Pepalali limagwiritsa ntchito sensor yophatikizika yamagawo awiri a hybrid stepper motor ndikupanga chowongolera chosinthika cha PI chotengera chowunikira ndi kuwongolera vekitala, chomwe chimapereka mawonekedwe osakhalitsa pakanthawi kosiyanasiyana. Kutengera masamu amtundu wa stepper motor, njira yowongolera ya PID ya stepper motor idapangidwa ndipo PID control algorithm imagwiritsidwa ntchito kuti ipeze kuchuluka kowongolera kuwongolera kayendedwe kagalimoto kupita kumalo omwe atchulidwa. Pomaliza, zimatsimikiziridwa ndi kuyerekezera kuti kuwongolera kumakhala ndi mawonekedwe abwino oyankha. Woyang'anira PID ali ndi ubwino wa mapangidwe osavuta, olimba kwambiri komanso odalirika kwambiri, koma sangathe kuthana ndi chidziwitso chosadziwika bwino mu dongosolo.

 

Stepper motor imatha kufananizidwa ndi chotsitsa chiyani? Pazosankha za stepper motor ndi gearbox muyenera kulabadira izi, ndipo ndi mtundu wanji wa gearbox womwe ungasankhidwe kuti ugwiritse ntchito limodzi?

 

1. Chifukwa cha stepper motor yokhala ndi reducer

 

Stepper galimoto kusintha pafupipafupi stator gawo panopa, monga kusintha athandizira zimachitika wa stepper galimoto pagalimoto dera, kuti akhale otsika-liwiro kayendedwe. Otsika-liwiro stepper galimoto podikirira popondapo lamulo, rotor ndi kuyima, mu otsika-liwiro makwerero, kusinthasintha liwiro adzakhala lalikulu kwambiri, pa nthawi ino, monga kusintha kwa ntchito mkulu-liwiro, akhoza kuthetsa vuto la kusinthasintha liwiro, koma makokedwe adzakhala osakwanira. Ndiko kuti, kuthamanga otsika kudzakhala kusinthasintha kwa makokedwe, ndi liwiro lalikulu sikokwanira makokedwe, kufunika ntchito reducer.

 

2. Stepper galimoto zambiri ndi reducer chiyani

 

Reducer ndi mtundu wa galimoto galimoto, nyongolotsi galimoto, galimoto - nyongolotsi galimoto, amene ali otsekeredwa mu casing okhwima, nthawi zambiri ntchito ngati reducer pakati pa prime mover ndi makina ntchito, pakati pa wamkulu mover ndi makina ntchito kapena actuator kuti agwirizane liwiro ndi kufala torque; reducer ali osiyanasiyana, malinga ndi mtundu wa kufala akhoza kugawidwa mu zida reducer, nyongolotsi zida reducer ndi mapulaneti zida reducer. Malinga ndi chiwerengero cha magawo kufala akhoza kugawidwa mu siteji imodzi ndi Mipikisano siteji reducer; malinga ndi mawonekedwe a giya amatha kugawidwa kukhala cylindrical gear reducer, bevel gear reducer ndi bevel-cylindrical gear reducer; molingana ndi mawonekedwe opatsirana amatha kugawidwa kukhala chochepetsera chosasinthika, shunt reducer ndi coaxial reducer. Stepper motor Assembly reducer ndi mapulaneti ochepetsera, nyongolotsi giya chochepetsera, parallel gear reducer, filament gear reducer.

 

 

Nanga bwanji stepper motor planetary reducer kulondola?

 

 

Kulondola kwa reducer kumatchedwanso kubwezeretsa chilolezo. Pamene mapeto otuluka akhazikika ndipo mapeto olowera amazunguliridwa mozungulira komanso mozungulira kuti apange torque yovotera + -2% torque pamapeto otuluka, pamakhala kusuntha kwakung'ono kumapeto kwa chochepetsera, ndipo kusamuka kwa angular ndiko kubwereranso chilolezo. Gawoli ndi "arc minutes", mwachitsanzo gawo limodzi mwa magawo asanu ndi limodzi a digiri. Miyezo yanthawi zonse yobwereranso imatanthawuza mbali yotulutsa ya gearbox. Stepper motor planetary reducer imakhala yolimba kwambiri, yolondola kwambiri (siteji imodzi imatha kupezeka mkati mwa mphindi imodzi), kuyendetsa bwino kwambiri (gawo limodzi mu 97% -98%), torque yayikulu / voliyumu, kusakonza, ndi zina zambiri.

 

Stepper galimoto kufala kulondola molondola si chosinthika, stepper galimoto kuthamanga ngodya anatsimikiza kwathunthu ndi sitepe kutalika ndi chiwerengero cha zimachitika, ndi chiwerengero cha zimachitika kuwerengera wathunthu, kuchuluka kwa digito si lingaliro la kulondola, sitepe imodzi ndi sitepe imodzi, masitepe awiri ndi masitepe awiri. Kulondola kwapano komwe kungawongoleredwe ndikulondola kwachilolezo chobwerera kwa gearbox ya pulaneti.

 

1. Njira yosinthira kulondola kwa spindle:kusinthika kwa pulaneti ya gearbox spindle rotational kulondola, ngati cholakwika cha makina a spindle chimakwaniritsa zofunikira, ndiye kuti kulondola kozungulira kwa spindle yochepetsera nthawi zambiri kumatsimikiziridwa ndi kunyamula. Chinsinsi chosinthira kulondola kwa kuzungulira kwa spindle ndikusintha chilolezo chonyamula. Kusunga chilolezo choyenera chonyamula ndikofunika kwambiri pakugwira ntchito kwa zigawo za spindle ndi moyo wobereka. Pakuti anagubuduza kubala, pamene pali lalikulu chilolezo, izo osati kupanga katundu anaikira anagubuduza thupi motsogozedwa mphamvu, komanso kutulutsa kwambiri maganizo ndende chodabwitsa mu kubala mkati ndi kunja mphete raceway kukhudzana, kufupikitsa kubala moyo, komanso kupanga spindle centerline kutengeka, zosavuta chifukwa kugwedera kwa mbali zopota. Chifukwa chake, kusintha kozungulira kozungulira kuyenera kunyamulidwa kale, Kupanga kusokoneza kwina mkati mwa mayendedwe, kuti apange mawonekedwe ena otanuka pakulumikizana pakati pa thupi logudubuza ndi msewu wamkati ndi wakunja wa mphete, motero kuwongolera kuuma kwa kunyamula.

2. Njira yosinthira kusiyana:ma gearbox a mapulaneti akuyenda adzatulutsa mikangano, zomwe zimapangitsa kusintha kukula, mawonekedwe ndi mawonekedwe apamwamba pakati pa zigawozo, ndi kuvala, kotero kuti kusiyana pakati pa zigawozo ndi kuwonjezeka, tiyenera kupanga zosinthika zosiyanasiyana kuti zitsimikizire kulondola kwa kayendedwe kachibale pakati pa zigawozo.

 

3. Njira yolipirira yolakwika:mbali okha kulakwitsa kudzera msonkhano yoyenera, kuti chodabwitsa cha mwapang'onopang'ono kuchepetsa pa nthawi yopuma, kuonetsetsa kulondola kwa zida kayendedwe trajectory.

 

1. Njira yolipirira yokwanira:chida chomwe chimayikidwa ndi chochepetsera chokha kuti chipangitse kukonzako chasamutsidwa ndi kusintha koyenera kwa tebulo la ntchito kuti athetse zotsatira zophatikizana za kulondola kwa zolakwikazo.
