Servo - ndichiyani? Makonzedwe, unsembe ndi ntchito actuator ndi

Anthu ambiri amafunsa funso limeneli: servo - ndichiyani? Chakale servo dongosolo zikuphatikizapo mota, pamalo sensa ndi atatu kuzungulira dongosolo ulamuliro (lamulo malo, mathamangidwe ndi panopa).

Mawu "servo" ndi la Latin chiyambi "servus", kwenikweni likumasuliridwa kuti "kapolo", "wothandizira", "sender".

The chipangizo makampani zomangamanga anachita wothandiza zigawo (chakudya galimoto mu chida makina, makina, etc.). Komabe, zinthu zasintha tsopano, ndi cholinga chachikulu cha actuator lake lili kukhazikitsa servos lapansi.

Khazikitsa ndi servo ayesedwa wolungama mu choncho pamene ochiritsira inverters zonse lolondola insufficiently.

Kugwiritsa ntchito zida apamwamba ayenera zipangizo, mkulu mlingo wa ntchito.

M'nkhaniyi tiphunzira za servo pa icho chiri ndi mmene limagwirira ntchito.

Madera a ntchito chipangizo

Masiku ano pamene zokha watenga malo amphamvu m'madera onse a zomangamanga, mamangidwe a njira kwambiri yunifolomu. Pa nthawi yomweyo pophatikiza abulusa ano munthu.

Pofuna kuzindikira servo icho chiri, inu muyenera kudziwa kuchuluka kwa chipangizo.

Zipangizo muli mwatsatanetsatane kamangidwe zimafika mu makina mafakitale ndi zipangizo makina ndi mwatsatanetsatane mkulu. Iwo wokwera pa zida kuboola machitidwe osiyanasiyana zoyendera ndi njira za chikhalidwe wothandiza.

Zipangizo Ambiri ntchito m'madera zotsatirazi:

• kupanga mapepala ndi ma CD;
• popanga a pepala zitsulo;
• zipangizo obrabatyvanii;
• Popanga zipangizo zoyendera;
• makampani nkhuni ;
• kupanga zomangira.

Servo pa thunthu galimoto

Pali zitsanzo zambiri za actuators kwa makina Nsapato ku opanga osiyana. Taganizirani magwiridwe a chipangizo monga actuator Nsapato ku "Avtozebra" opanga zoweta. chipangizo lakonzedwa magalimoto Russian, koma osati. Mwachitsanzo, zikhoza kugwiritsidwa ntchito mu galimoto "Reno Logan".

Malinga ndi maganizo wosuta, mamangidwe amapereka mayiko. Timatha inu chitonthozo cha galimoto, kugwira kutsegula ndi kutseka kwa thunthu.

Chipangizo umalamulidwa ndi mabatani wokwera m'katikati galimoto kapena kiyi fob ma siginalo.

Chifukwa ntchito zosiyanasiyana zoimbira za

Chifukwa kawirikawiri wa actuators ndi:

• Kuthekera kulamulira, yodziwika ndi lolondola mkulu ndi ntchito khola;
• osiyanasiyana ulamuliro liwiro;
• mkulu mlingo wa asanazolowere kulowelela kwa ena;
• ang'onoang'ono kukula ndi kulemera kwa chipangizo.

Mfundo ntchito actuator ndi

Kodi chipangizo? Servo, mfundo ya ntchito zachokera ndemanga imodzi kapena zingapo chizindikiro zokhudza zonse, paulimi chinthu. Linanena bungwe anasonyeza chipangizo ndi athandizira, m'mene pali poyerekeza ndi kanthu galimoto.

Features wa limagwirira ndi

chipangizo servo lili ndi zinthu ziwiri zazikulu:

• mphamvu kuonjezera mphamvu;
• ndemanga deta kulankhulana mapulogalamu.

Amveke chofunika kwa cholinga, kuti kufunika mphamvu linanena bungwe ndi mkulu (akubwera kuchokera kwa anthu wamba) ndi pa mlingo wake polowera ndi negligible.

Feedback - ndi wina kuposa circuitry chatsekedwa-kuzungulira, momwe zizindikiro si chikufanana pa athandizira ndi linanena bungwe. Zimenezi ntchito pofuna kuchepetsa.

Choncho mapeto kuti mwachindunji njira malangizo ndi chopatsilira mphamvu, ndi zosiyana - ndi chopatsilira wa mudziwe chimene chili chofunika kulamulira molondola.

Zakudya ndi cholumikizira chipangizo pinout

Servo mfundo ya ntchito ntchito mu masanjidwe wailesi womwe, nthawi zambiri ali ochititsa zitatu:

1. Kulankhulana. Pa zimafalitsidwa ulamuliro zimachitika. Childs, waya ndi akuda oyera, achikasu kapena wofiira.
2. Kudyetsa. ake mlingo mphamvu ranges kuchokera 4.8 kuti 6 V. Izi kawirikawiri waya wofiira.
3. Ground. Waya zakuda kapena zofiirira.

abulusa Makulidwe

Malinga ndi kutalika kwa wagawo ndi m'magulu atatu:

• microactuators;
• muyezo kusinthidwa;
• chachikulu chipangizo.

Pali actuators, ndi zizindikiro zina za kukula, koma koposa mitundu mlandu 95% zipangizo zonse.

Makhalidwe waukulu wa mankhwala

ntchito actuator amakhala ndi magawo awiri zikuluzikulu: a kasinthasintha liwiro ndi khama m'dzenjewo. Ubwino woyamba ndi muyeso wa nthawi, imene anayeza masekondi. Chimaonekera mwa mphamvu mu makilogalamu / cm, kuti, chimene mlingo wa khama kukhala asilikali ku likulu la kasinthasintha.

Nthawi zambiri, chizindikiro ichi chimadalira pa chipangizo chachikulu komwe, ndiyeno kokha chiwerengero cha transmissions zida ndi zigawo zikuluzikulu ntchito zida za.

Monga tanenera kale, tsopano kubala kuti makinawa ntchito kwa index voteji wa 4.8 kuti 6 V. Nthawi zambiri, chithunzi ndi 6 V. Komabe, si zitsanzo zonse anapangidwa kuti osiyanasiyana voltages. Nthawi zina servo galimoto ikutha yekha pa 4.8 V kapena kokha 6 (lomaliza kasinthidwe opangidwa kwambiri kawirikawiri).

Analogi ndi kusinthidwa digito

Zaka zingapo zapitazo, onse servo dera anali analogi. Tsopano apo ndi mamangidwe yadigito. ndi kusiyana kwa ntchito zawo zomwe? Tiyeni titsegule ku nkhani boma.

Ku kampani Futaba lipoti kuti m'mbuyomu khumi servos zitsulo osiyanasiyana ntchito zabwino zambiri luso kuposa kale komanso kukula yaing'ono, mkulu-liwiro ndi index mbali torsion.

gawo lotsiriza la chitukuko - zikamera zipangizo pa maziko yadigito. mayunitsi ndi ubwino kwambiri ngakhale Motors a mtundu wokhometsa. Ngakhale pali ena downsides.

Kunja osiyana analogi ndi zipangizo yadigito. Kusiyana zinalembedwa yekha pa zipangizo mavabodi. M'malo tchipisi pa digito microprocessor wagawo Tingaone kupenda wolandirayo chizindikiro. Iye amayang'anira galimoto ndi.

Kwathunthu kulakwa kunena kuti analogi ndi kusinthidwa digito ndi mwapadera mu ntchito. Iwo amakhala ndi injini chomwecho, makina ndi potentiometers (variable resistors).

Chachikulu kusiyana ndi njira processing ukubwera wolandila chizindikiro ndiponso ulamuliro engine. Awiri mphamvu servo umaperekedwa ndi wailesi chizindikiro chomwecho.

Choncho, zimaonekeratu, servo, ndichiyani?

Mfundo zikugwira ntchito ya zosintha analogi

Chifukwa analogi chizindikiro angafanane kusinthidwa kwa malo atsopano a servomotor, ndiye galimoto ya akulowa mkuzamawu, kuchititsa kayendedwe ka galimoto mu malo anakonzeratu za anasonyeza ndondomeko pafupipafupi ndi nthawi 50 pa mphindi. Ichi ndi mlingo osachepera nthawi ayankhe. Ngati inu ingapendame chogwirira pa chopatsilira, ndiye servo adzayamba kulowa nyemba chidule, imeneyi pakati pawo wofanana 20 m / gawo. Pakati nyemba kanthu akulowa injini, ndi amadza kuchokera kunja mungathe kusintha ntchito chipangizo kwina kulikonse. Izi imeneyi nthawi amatchedwa "zone akufa."

Mfundo ntchito za kamangidwe digito

zipangizo Intaneti ntchito purosesa chapadera chimene chigwira ntchito pa mafurikwense mkulu. Ndi njira wolandirayo chizindikiro, ndipo akutumiza ulamuliro nyemba kwa galimoto ndi pafupipafupi chizindikiro nthawi 300 pa mphindi. Popeza mlingo zochitika ndi apamwamba kwambiri, ndi zimene zili zambiri mofulumira amagwira malo bwino. Izi mulingo woyenera wokhudzana ndi mkulu torsion. Komabe, njira imeneyi kumafuna mphamvu, kotero batire ntchito limagwirira analogi, mu ndondomeko imeneyi itsikire mwamsanga.

Komabe, mapulogalamuwanso onse amene anakumanapo ndi chitsanzo digito, kuti kusiyana kwake ndi kapangidwe analogi kwambiri zimene sakanafuna yayitali kudyedwa.

Pomaliza

kusankha adzakhala Anzawo digito, ngati mukufuna:

• mkulu mlingo wa kusamvana ;
• osachepera chiwerengero cha "mabacteria akufa";
• yeniyeni mlingo malo;
• ayankhe mofulumira lamulo;
• invariable mphamvu kutsinde pa kasinthasintha;
• wamphamvu kwambiri mlingo.

Tsopano inu mukudziwa chomwe actuator ndi momwe ntchito.
