Kuyerekeza kwakukulu pakati pa mota ya micro stepper ndi mota ya N20 DC: nthawi yosankha torque ndi nthawi yosankha mtengo?

Pakupanga zida zolondola, kusankha gwero la mphamvu nthawi zambiri kumatsimikizira kupambana kapena kulephera kwa polojekiti yonse. Pamene malo opangidwira ali ochepa ndipo kusankha kuyenera kupangidwa pakati pa ma micro stepper motors ndi ma N20 DC motors omwe amapezeka paliponse, mainjiniya ambiri ndi oyang'anira kugula zinthu adzakhala akuganiza mozama: kodi ayenera kutsatira kuwongolera kolondola ndi mphamvu yayikulu ya ma stepper motors, kapena kusankha phindu la mtengo ndi kuwongolera kosavuta kwa ma DC motors? Ili si funso laukadaulo lokha losankha zambiri, komanso chisankho chachuma chokhudzana ndi mtundu wa bizinesi ya polojekitiyi.

I、 Chidule Chachidule cha Zinthu Zazikulu: Njira Ziwiri Zosiyana Zaukadaulo

Mota yaying'ono yoyendera:mfumu yolondola ya ulamuliro wotseguka

Mfundo yogwirira ntchito:Kudzera mu digito pulse control, pulse iliyonse imafanana ndi kusuntha kokhazikika kwa angular

Ubwino waukulu:malo olondola, mphamvu yogwira ntchito kwambiri, kukhazikika kwabwino kwambiri kotsika liwiro

Ntchito wamba:Makina osindikizira a 3D, zida zolondola, maloboti olumikizirana, zida zachipatala

N20 DC Mota: Yankho Loyamba Logwiritsa Ntchito Mtengo Moyenera

Mfundo yogwirira ntchito: Liwiro la ulamuliro ndi torque kudzera mu voteji ndi mphamvu yamagetsi

Ubwino waukulu: mtengo wotsika, kuwongolera kosavuta, kuthamanga kwambiri, kugwiritsa ntchito mphamvu zambiri

Ntchito wamba: mapampu ang'onoang'ono, makina otsekera zitseko, mitundu ya zoseweretsa, mafani opumira mpweya

II、 Kuyerekeza Kwambiri kwa Miyeso Isanu ndi Itatu: Deta Imavumbula Chowonadi

1. Kulondola kwa malo: kusiyana pakati pa mulingo wa milimita ndi mulingo wa sitepe

Mota yaying'ono yoyendera:Ndi ngodya yanthawi zonse ya 1.8 °, imatha kufika pa 51200 kugawa/kuzungulira kudzera pa micro stepper drive, ndipo kulondola kwa malo kumatha kufika ± 0.09 °

N20 DC mota: palibe ntchito yokhazikika yokhazikika, imafuna encoder kuti ikwaniritse kuwongolera malo, encoder yowonjezera nthawi zambiri imapereka 12-48CPR

Chidziwitso cha mainjiniya: Muzochitika zomwe zimafuna kuwongolera kwathunthu malo, ma stepper motors ndi chisankho chachilengedwe; Pa mapulogalamu omwe amafunikira kuwongolera liwiro lapamwamba, ma DC motors angakhale oyenera kwambiri.

2. Makhalidwe a torque: Sungani masewera pakati pa torque ndi curve ya torque ya liwiro

Mota yaying'ono yoyendera:yokhala ndi mphamvu yogwira ntchito bwino kwambiri (monga mota ya NEMA 8 mpaka 0.15N · m), mphamvu yokhazikika pa liwiro lotsika

N20 DC mota:mphamvu ya torque imachepa ndi liwiro lowonjezeka, liwiro lalikulu lopanda katundu koma mphamvu yochepa ya rotor yotsekedwa

Kuyerekeza kwa Deta Yeniyeni ya Mayeso:

3. Kuvuta kwa ulamuliro: kusiyana kwaukadaulo pakati pa kugunda kwa mtima ndi PWM

Kuwongolera mota wa stepper:imafuna woyendetsa wodzipereka kuti apereke zizindikiro za kugunda kwa mtima ndi kuwongolera

Kuwongolera mota ya DC:Dongosolo losavuta la H-bridge limatha kupangitsa kuti lizizungulira kutsogolo ndi kumbuyo komanso kulamulira liwiro

4. Kusanthula Mtengo: Kuganizira za Mtengo wa Chigawo mpaka Mtengo Wonse wa Dongosolo

Mtengo wa galimoto: Galimoto ya N20 DC nthawi zambiri imakhala ndi phindu lalikulu pamtengo (kugula kwakukulu pafupifupi madola 1-3 aku US)

Mtengo wonse wa dongosolo: Dongosolo la mota ya stepper limafuna madalaivala owonjezera, koma dongosolo loyika magalimoto a DC limafuna ma encoder ndi owongolera ovuta kwambiri.

Malingaliro okhudza kugula zinthu: Mapulojekiti ang'onoang'ono a kafukufuku ndi chitukuko angayang'ane kwambiri pa mtengo wa mayunitsi, pomwe mapulojekiti opanga zinthu zambiri ayenera kuwerengera mtengo wonse wa makina.

Chachitatu、 Buku Lotsogolera Zosankha: Kusankha Molondola kwa Zochitika Zisanu Zogwiritsira Ntchito

Chitsanzo 1: Mapulogalamu omwe amafunikira kuwongolera bwino malo

Sankhani koyenera:Mota yaying'ono yoyendera

Chifukwa:Kuwongolera kotseguka kumatha kukwaniritsa malo olondola popanda kufunikira kwa machitidwe ovuta oyankha

Chitsanzo:Kusuntha kwa mutu wa extrusion wa chosindikizira cha 3D, malo olondola a nsanja ya maikulosikopu

Chitsanzo chachiwiri: Kupanga zinthu zambiri zomwe zimakhala zotsika mtengo kwambiri

Sankhani koyenera:N20 DC mota

Chifukwa:Kuchepetsa kwambiri ndalama za BOM pamene mukuonetsetsa kuti ntchito yoyambira ikugwira ntchito

Chitsanzo: Kuwongolera ma valavu a zida zapakhomo, galimoto yoyendetsera zoseweretsa yotsika mtengo

Chitsanzo 3: Kugwiritsa ntchito zinthu zopepuka komanso malo ochepa kwambiri

Sankhani koyenera: Mota ya N20 DC (yokhala ndi bokosi la gearbox)

Chifukwa: Kakang'ono, kamene kamapereka mphamvu yokwanira yotulutsa mphamvu pamalo ochepa

Chitsanzo: kusintha kwa gimbal ya drone, malo olumikizirana ang'onoang'ono a robot

Chitsanzo 4: Kugwiritsa ntchito moyimirira komwe kumafuna mphamvu yogwira ntchito mwamphamvu

Sankhani koyenera:Mota yaying'ono yoyendera

Chifukwa: Imatha kusungabe malo ake magetsi akatha, palibe chipangizo choyendetsera mabuleki chomwe chikufunika

Chitsanzo:Njira yaying'ono yokwezera, kukonza ngodya ya kamera

Chitsanzo 5: Mapulogalamu omwe amafunikira liwiro lalikulu

Sankhani koyenera: N20 DC mota

Chifukwa: PWM imatha kukwaniritsa bwino malamulo akuluakulu a liwiro

Chitsanzo: Kuwongolera kayendedwe ka madzi a mapampu ang'onoang'ono, kuwongolera liwiro la mphepo pazida zopumira mpweya

IV、 Yankho losakanizidwa: kuswa malingaliro a binary

Mu ntchito zina zogwira ntchito bwino, kuphatikiza matekinoloje awiri kungaganizidwe:

Kuyenda kwakukulu kumagwiritsa ntchito mota ya stepper kuti zitsimikizire kulondola

Ntchito zothandizira zimagwiritsa ntchito ma DC motors kuti azilamulira ndalama

Kuyenda mozungulira mozungulira kumapereka njira yothetsera mavuto ngati pakufunika kudalirika

Chitsanzo cha zatsopano: Pakupanga makina apamwamba a khofi, mota yoyendera imagwiritsidwa ntchito kuonetsetsa kuti malo oyimitsa bwino ponyamula mutu, pomwe mota ya DC imagwiritsidwa ntchito kuwongolera mtengo wa pampu yamadzi ndi chopukusira.

V、 Zochitika Zamtsogolo: Momwe Kukula kwa Ukadaulo Kumakhudzira Zosankha

Kusintha kwa ukadaulo wa stepper motor:

Kapangidwe kosavuta ka makina anzeru a stepper motor okhala ndi driver wophatikizidwa

Kapangidwe katsopano ka maginito kokhala ndi mphamvu zambiri

Mitengo yakhala ikutsika chaka ndi chaka, ikulowa mu ntchito zapakati

Kupititsa patsogolo ukadaulo wa magalimoto a DC:

Mota ya DC yopanda brush (BLDC) imapereka moyo wautali wautumiki

Ma mota anzeru a DC okhala ndi ma encoder ophatikizidwa akuyamba kuonekera

Kugwiritsa ntchito zipangizo zatsopano kukupitirira kuchepetsa ndalama

VI、 Chithunzi chogwiritsira ntchito posankha njira

Potsatira njira zotsatirazi zopangira zisankho, zisankho zitha kupangidwa mwadongosolo:

Mapeto: Kupeza Kugwirizana Pakati pa Malingaliro Aukadaulo ndi Zenizeni Za Bizinesi

Kusankha pakati pa mota ya micro stepper kapena mota ya N20 DC si chisankho chophweka. Chimaphatikizapo luso logwirizanitsa kufunafuna kwa mainjiniya magwiridwe antchito ndi kuwongolera ndalama zomwe zimagulidwa.

Mfundo zazikulu zopangira zisankho:

Ngati kulondola ndi kudalirika ndiye zinthu zofunika kwambiri, sankhani mota yoyendera

Ngati mtengo ndi kuphweka zikutsogolera, sankhani mota ya DC

Mukakhala pakati, werengani mosamala ndalama zonse zomwe zimagwiritsidwa ntchito pa dongosolo ndi ndalama zosamalira kwa nthawi yayitali.

Mu nthawi ya ukadaulo yomwe ikusintha mofulumira masiku ano, mainjiniya anzeru satsatira njira imodzi yaukadaulo, koma amapanga zisankho zomveka bwino kutengera zoletsa ndi zolinga zamabizinesi za polojekitiyi. Kumbukirani, palibe injini "yabwino kwambiri", koma yankho "loyenera kwambiri" lokha.
