1. Sei kusarudza servo injini uye danho injini zvakarurama?
It zvikurukuru kunobva kushanda. Kazhinji, inoda kuona: yezvakaita mutoro (chinjikira kana wehunyambiri mutoro), torque, inertia, kumhanya, yakarurama, kumhanyisa uye deceleration nezvimwe zvinodiwa, yokumusoro kuzvidzora zvinodiwa (akadai chengarava inowanikwa uye kukurukura zvinodiwa), uye huru kuzvidzora muoti ndozvinoita, torque kana kumhanya muoti. Power zvitengeswa ndiye DC kana AC simba, kana bhatiri simba, voltage siyana. Kuona muenzaniso injini uye muchiridzira tikachirega kana controller.
- Musiyano uri pakati AC servo injini uye DC servo motokari?
- Pindura: DC servo injini rakakamurwa bhurasho injini uye hapana bhurasho injini.
- The mumakwenzi injini ine zvakanakira yakaderera mutengo, nyore mamiriro, hombe pokutangira torque, yakafara kumhanya-siyana, nyore kuzvidzora uye nazvo, asi zviri nyore kuramba, remagetsi chipingaidzo uye zvakatipoteredza zvinodiwa. Saka unogona kushandiswa zvakafanana maindasitiri uye vehurumende zviitiko nehanya mutengo.
- BLDCM ane vhoriyamu duku, chiedza uremu, hombe goho, kutsanya mhinduro, kumhanya, inertia duku, kumeso kutenderera uye irambe torque. The kuzvidzora omei, uye zviri nyore kuziva intellectualization. Electronic commutation muoti iri kuchinja, izvo zvinogona mativi chinozunguzirwa commutation kana Sine Wave commutation. Motor Nokuraramisa vakasununguka, mukuru kushanda, pasi uchishandisa tembiricha, remagetsi nemwaranzi iri dikisa, upenyu hurefu, inogona kushandiswa munharaunda dzakasiyana-siyana.
- AC servo injini ariwo brushless injini, iyo rakakamurwa synchronous uye asynchronous motokari. Parizvino, synchronous injini iri kazhinji kushandiswa inofamba achidzora. It ane guru simba siyana uye anogona kuwana simba guru. Kufadza rotational nokukurumidza yakaderera makuru inertia, uye zvinoderedza nokukurumidza pamwe nekukura simba. Saka, zvakakodzera kuti kushanda kuderedzwa nokukurumidza uye wakatsiga oparesheni; asynchronous injini ine kumhanya uye pasi kururama pane synchronous injini, iyo inowanzoshandiswa sezvo chokurukisa injini zvishandiswa.
- Chii chinofanira Aizvirumbidza paaishandisa servo injini?
- Pindura: cheki sezvinotevera pamberi simba pamusoro oparesheni:
a) Kuti simba romugove voltage kwakakodzera (pamusoro-voltage angangoda chikonzero kuvadza nemotokari module); nokuti DC chiyamuro, + / - polarity harifaniri kwakabatana zvisizvo, uye kana injini womuenzaniso kana ano ezvinhu ukoshi pamusoro nemotokari controller kwakakodzera (kunyanya guru pakutanga);
b) The kudzora chiratidzo mutsetse anofanira zvakasimba kwakabatana uye kudzivirirwa dambudziko (akadai yakakoswa peya) anofanira paChidzidzo maindasitiri nzvimbo;
c) Usaita batanidza ose waya kuti vanoda kuti kwakabatana pakutanga, chete batanidza navo inokosha maitiro, uye ipapo batanidza navo zvishoma nezvishoma mushure hurongwa anomhanya kwazvo. d) Iva nechokwadi kuti chokwadi kuti grounding nzira iri pachena, kana kushandiswa kuyangarara mhepo pane unobatanidza. e) Pasina hafu yeawa pashure kutanga kushanda, vanonyatsoongorora mamiriro injini, akadai kana sangano iri kuipa, inzwi uye tembiricha simukai, uye pakarepo kumisa muchini kuchinja kana paine dambudziko rinowanikwa.
4 zvinobvira kudzora servo injini achishandisa yokukurukurirana zvakananga?
Hongu, zviri zvakare nyore. Rinongova nyaya nokukurumidza. Zvinofanira kushandiswa mafomu kuti urege inoda mhinduro rakawandisa nokukurumidza. Kana zvinoda kutsanya mhinduro kuzvidzora parameters, zviri nani kushandisa servo inofamba kudzora kadhi. Kazhinji, rine DSP uye mukuru-nokukurumidza pfungwa kubudiswa redunhu kuzadzisa mukuru-nokukurumidza uye yakakwirira-zvakarurama inofamba kuzvidzora. Akadai S kumhanyisa, Multi akabatana interpolation, nezvimwewo 5. Ko encoder chikamu servo injini anofanira disassembled?
Zvinonzi arambidzwa nekukatanura, nokuti Goldstone Chip mu bumbiro dhisiki zviri nyore mitswi, uye pashure kupinda guruva, upenyu basa uye kururama haangazozikamwi inosimbiswa, izvo zvinoda nyanzvi yokuzvigadzirisa.
- Ko servo injini anofanira disassembled yokuzvigadzirisa kana refitted?
Zviri nani kudzokera kugadzirwa chirimwa yokuzvigadzirisa. Zvakaoma kuisa injini shure wacho hwepakutanga pasina nenyanzvi midziyo pashure disassembling injini, uye Clearance pakati kutenderera stators ari injini hazvigoni unovimbisa. Chokupika ari rinobva simbi zvinhu yaparadzwa, kunyange zvichiguma nokurasika excitation, uye injini torque ipfupi kwazvo.
- Sei kusarudza zvakanaka simba romugove nokuda kushanda?
Zvinokurudzirwa kuti simba romugove voltage ndiyo 10% - 50% kupfuura kufadza kwaida voltage. Ichi chikamu muzana dzinosiyana-siyana zvichienderana KT, Ke, uye voltage donhwe munyika. Kukosha kuitika pamusoro mutyairi kunofanira kwakakwana kununura simba zvinodiwa kushanda. Yeuka kuti goho voltage kuti mutyairi rakasiyana romugove voltage, saka goho kwazvino mutyairi rakasiyana mazano ano. Kuti aone zvakakodzera kupiwa ano, zvinokosha kuverenga simba zvinodiwa zvose chikumbiro ichi, uye kuwedzera 5%. Maererano yokuita I = P / V, runodiwa ano mutengo kunogona kuwanikwa.

- Sei zvakohwewa kuti servo mutyairi uye servo gadziriro?
- Kana pasina voga pakati AC simba romugove uye mutyairi DC bhazi (akadai transformer), regai zvakohwewa asiri kure chiteshi of DC bhazi kana asiri kure chiratidzo, izvo zvingaita kukuvadza midziyo uye munhu zvinokuvadza. Nokuti AC vanhuwo voltage haisi pasi, pangava yakakwirira voltage pakati DC bhazi pasi nenyika.
- In dzakawanda servo mugadziriro, zvose pamungawirirana uye nenyika zvakabatanidzwa panguva chiratidzo pakuguma. Pasi loop kunotangira vakawanda kubatana modes iri nyore sei ruzha uye zvinowanisa iyerere panguva dzakasiyana bhuku pfungwa.
- Kuti vachengete murayiro bhuku voltage kuramba, chiratidzo pamusoro mutyairi zvakabatana chiratidzo pakati controller. Zvichakubatsirawo kwakabatana pasi nechitarisiko simba nemushonga, izvo huchachinja nokushanda controller uye mutyairi (akadai 5V simba nerubatsiro encoder). d. Pane nzira dzakawanda zvakohwewa nhovo. Yakarurama kudzivirirwa pasi ndiro riri bhuku zvinogona pfungwa mukati mudunhu raro. Pfungwa iyi inoenderana nokuti ruzha panobva uye mugamuchiri vari makateyiwa kana akayangarara panguva imwe chete. Iva nechokwadi kuti nhoo iri makateyiwa panguva nguva kuitira kuti pasi pari hakurevi ichiyerera kuburikidza nhoo.
- Nei asina yokuderedza uye gwenya machisi panguva mureza torque pfungwa?
Kana tikafunga kufadza chichiitwa torque kunotangira injini kubudikidza yokuderedza, vazhinji rutapudzo ratios vachava kure kusapfuudza torque pachiyero yokuderedza.
Kana tichida kugadzira mumwe yokuderedza anoenderana zvizere torque, pachava anofambidzana zvakawandisa yomunyika rachulis ari yokuderedza (vhoriyamu guru uye vazhinji zvinhu).
Izvi zvichaita kuti chigadzirwa mutengo mukuru uye kutyora "mukuru kuita, Vhoriyamu duku" nheyo chigadzirwa.
The vakawanda maumbirwo maindasitiri robhoti yemagetsi servo kwava matatu namahwindo-loop kuzvidzora, zvinoti ano loop, kukurumidza loop uye nzvimbo loop. Kazhinji, nokuti AC servo mutyairi, nzvimbo kuzvidzora, kumhanya kuzvidzora, torque kuzvidzora uye mamwe mabasa anogona kuziva ne manually kwarinovirira womukati shanda parameters.
