1. Kodi kusankha servo galimoto ndi sitepe galimoto molondola?
Makamaka zimadalira ntchito. Nthawi zambiri pamafunika kudziwa: chikhalidwe cha katundu (yopingasa kapena ofukula katundu), makokedwe, inertia, liwiro molondola, mathamangitsidwe ndi deceleration ndi zofunika zina, amafuna chapamwamba ulamuliro (monga amafuna doko mawonekedwe ndi kulankhulana), ndi chachikulu ulamuliro mode ndi udindo, makokedwe kapena liwiro mode. Mphamvu okwanira ndi DC kapena AC mphamvu, kapena mphamvu batire, voteji osiyanasiyana. Kudziwa chitsanzo cha galimoto ndi galimoto m'munsili kapena Mtsogoleri.
- Kodi kusiyana AC servo galimoto ndi DC servo galimoto chiyani?
- Yankho: DC servo galimoto lagawidwa galimoto burashi ndipo palibe galimoto burashi.
- The burashi galimoto Ubwino wa mtengo wotsika, dongosolo losavuta, lalikulu poyambira makokedwe, lonse liwiro osiyanasiyana, ulamuliro zosavuta ndi zina, koma zili kukhalabe, mu atomu chopinga ndiponso zofunika zachilengedwe. Choncho angagwiritsidwe ntchito wamba mafakitale ndi yapachiweniweni nthawi tcheru mtengo.
- BLDCM ali buku laling'ono, kulemera kuwala, linanena bungwe lalikulu, yankho mwaliwiro liwiro, inertia yaing'ono, kasinthasintha yosalala ndi makokedwe khola. kulamulira ndi zovuta, ndipo n'zosavuta kuzindikira intellectualization. The zamagetsi commutation mode ndi kusintha, zimenezi lalikulu yoweyula commutation kapena sine yoweyula commutation. Njinga yokonza free, dzuwa mkulu, otsika opaleshoni kutentha, cheza mu atomu ndi laling'ono kwambiri, moyo wautali, angagwiritsidwe ntchito m'malo osiyanasiyana.
- AC servo galimoto alinso brushless galimoto, amene lagawidwa galimoto synchronous ndi asynchronous. Pakali pano, synchronous galimoto amagwiritsidwa ntchito mu ulamuliro apaulendo. Iwo ali lalikulu mphamvu zosiyanasiyana ndipo akhoza kukwaniritsa mphamvu yaikulu. The pazipita rotational liwiro ndi otsika ndi inertia lalikulu, ndipo amachepetsa mofulumira ndi kuchuluka kwa mphamvu. Choncho, oyenera kugwiritsa ntchito otsika liwiro ndi ntchito khola; asynchronous galimoto ali liwiro mkulu ndi otsika molondola kuposa galimoto synchronous, amene amagwiritsidwa ntchito monga galimoto ndi spindle zida.
- Kodi ayenera kupeleka chidwi ku ntchito servo mota?
- Yankho: cheke motere pamaso mphamvu pa ntchito:
a) Kaya magetsi voteji kuli koyenera (pa-voteji zambiri chifukwa kuwonongeka kwa gawo pagalimoto); kwa DC athandizira, + / - polarity sayenera chikugwirizana molakwika, ndipo ngati galimoto chitsanzo phindu panopa akukhala pa Mtsogoleri pagalimoto kuli koyenera (osati waukulu kwambiri pa chiyambi);
b) Mfundo ulamuliro mbendera adzakhala titsimikize chokhudzana ndi vuto kutetezedwa (monga awiri zopotoka) amene tikambirane pa malo mafakitale;
c) Kodi si kulumikiza mawaya onse kuti kufunika chikugwirizana pachiyambi, monga kulumikiza iwo dongosolo ofunika kwambiri, kenako kulumikiza iwo pang'onopang'ono dongosolo limayenda bwino. d) Onetsetsani kuti onetsetsani njira grounding momveka bwino, kapena kugwiritsa ntchito akuyandama mpweya m'malo kulumikiza. e) Pasanathe theka la ola pambuyo chiyambi cha ntchito, amayang'anitsitsa boma la galimoto, monga ngati gululi yachibadwa, phokoso ndi kuwuka kutentha, ndipo nthawi yomweyo kusiya makina a kusintha ngati vuto lililonse wapezeka.
4 kodi n'zotheka kulamulira mwachindunji ndi servo galimoto mwa kulankhulana?
Inde, komanso yabwino. Ndi nkhani ya liwiro. Izo ntchito ntchito kuti sitingafunikire kutero kwambiri ayankhe liwiro. Ngati amafuna kudya ayankhe kulamulira magawo, ndi bwino khadi ntchito servo zoyenda kulamulira. Nthawi zambiri, iwo ali DSP ndi mkulu-liwiro dera mfundo processing kukwaniritsa mkulu-liwiro ndi mkulu-mwatsatanetsatane zoyenda kulamulira. Monga m mathamangitsidwe, Mipikisano olamulira sanaike, etc. 5. Kodi encoder mbali ya servo galimoto disassembled?
Iwo analetsedwa disassemble, chifukwa khwatsi Chip mu litayamba malamulo n'zosavuta osokoneza, ndi atachita fumbi, moyo utumiki ndi olondola sati kungakupatseni chimene chimafuna yokonza akatswiri.
- Kodi servo galimoto disassembled chifukwa tikukonza kapena refitted?
Ndi bwino kuti abwerere kwa mbewu kupanga chifukwa tikukonza. Ndi zovuta kukhazikitsa injini ku boma wapachiyambi popanda zida akatswiri pambuyo kuziphwasula galimoto, ndi chilolezo pakati pa stators onsewo ya galimoto sangathe kungakupatseni. ntchito nkhani maginito zitsulo zikadzawonongedwa, ndipo zotsatira zake ndi imfa ya malemeredwe, ndi galimoto makokedwe yafupika kwambiri.
- Kodi kusankha bwino mphamvu chakudya cha ntchito?
Ndi bwino kuti magetsi voteji ndi 10% - 50% kuposa pazipita chofunika voteji. kuchuluka izi mosiyanasiyana malingana kt, Ke, ndi voteji akuponya dongosolo. Mtengo atsopano a dalaivala ayenera kokwanira kupulumutsa mphamvu wofunikila ntchito. Kumbukirani kuti linanena bungwe voteji a dalaivala ndi osiyana ndi mwa kundipatsako voteji, kotero linanena bungwe panopa dalaivala ndi osiyana athandizira panopa. Pofuna kudziwa zoyenera kotunga panopa, m'pofunika kuwerengetsa zofunika mphamvu zonse za ntchito imeneyi, ndi kuonjezera ndi 5%. Malinga ndi chilinganizo cha Ine = P / V, chofunika mtengo panopa akhoza kuwapeza.

- Kodi kuuluka dalaivala servo ndi servo dongosolo?
- Ngati palibe kudzipatula pakati pa AC magetsi ndi dalaivala DC basi (monga thiransifoma), musati kuuluka sanali akutali doko la DC basi kapena osakhala akutali chizindikiro zimene zingachititse zida kuwonongeka ndi kuvulala munthu. Chifukwa AC wamba voteji si dziko lapansi, pakhoza kukhala voteji mkulu pakati basi DC pansi ndi dziko lapansi.
- M'magulu kwambiri servo, onse mumafanana ndi dziko lapansi ogwirizana kumapeto chizindikiro. Nthaka kuzungulira kwaiye modes angapo kugwirizana mosavuta anakhudzidwa ndi phokoso ndipo amapanga ikuyenda pa mfundo zosiyanasiyana pakuyenerera.
- Pofuna kusunga lamulo Buku voteji zonse, mbendera ya dalaivala chikugwirizana ndi chizindikiro cha Mtsogoleri wa. Komanso olumikizidwa kwa nthaka ya kotunga kunja mphamvu zidzakhudza ntchito Mtsogoleri ndi dalaivala (monga 5V mphamvu kotunga encoder). d. Pali njira zambiri kuuluka chikopa. Olondola kutetezedwa pansi ndi pa Buku angathe mfundo mkati dera lake. Mfundo zikudalira phokoso gwero ndi wolandila ndi otsendereka kapena akuyandama pa nthawi yomweyo. Onetsetsani kuti chishango ndi otsendereka pa mfundo yomweyi kuti nthaka panopa si ikuyenda mwa chikopa.
- N'chifukwa chiyani si reducer ndi galimoto machesi pa nsonga muyezo makokedwe?
Ngati kuganizira pazipita mosalekeza makokedwe kwaiye ndi injini kudzera reducer, ambiri magawanidwe kuchepetsa adzakhala kuposa makokedwe mlingo wa reducer lapansi.
Ngati tifuna kupanga chilichonse reducer kuti agwirizane makokedwe zonse, padzakhala ma zambiri magiya mkati mwa reducer ndi (buku lalikulu ndi zipangizo zambiri).
Izi azitentha mtengo mankhwala mkulu ndi zosemphana "mkulu ntchito, buku laling'ono" mfundo ya mankhwala.
Kapangidwe ambiri mafakitale loboti dongosolo magetsi servo ndi atatu chatsekedwa-kuzungulira kulamulira, kuzungulira ndicho panopa, liwiro kuzungulira ndi malo kuzungulira. Ambiri, chifukwa AC servo dalaivala, ulamuliro malo, kulamulira liwiro, ulamuliro makokedwe ndi ntchito zina zikhoza anazindikira mwa pamanja atakhala ake magawo ntchito mkati.
