Ukusombulula iingxaki zokuphazamiseka kwe-Electromagnetic (EMI) kwiServo Motor Stages

Besisakha izigaba ezisebenzisa izandla nezisebenzisa iimoto kangangeminyaka engaphezu kwe-9. Sikwadala namaqonga okulungelelanisa azenzekelayo. Ngoko ke sibone iingxaki ezininzi ze-EMI. Ezinye zilula. Ezinye zikwenza ufune ukutsala iinwele zakho.

Ukuba usebenza ngolungelelwaniso lwe-optical, uyayazi imvakalelo. Iqonga liyashukuma. Ikhamera ijongeka. Umfanekiso unomsindo. Indawo ivaliwe ngee-microns ezimbalwa. Ujonga indlela esebenza ngayo. Yonke into iqinile. Emva koko uyaqonda ukuba ingxaki ayisiyoyomatshini. Yingxolo yombane.

Esi sikhokelo senzelwe abathengi, iinjineli, kunye naye nabani na ofunainqanaba lemoto yeservooko kusebenza ngokwenene kumzi-mveliso wokwenyani. Akukho nto ilula. Zizinto nje eziluncedo esizifundileyo kwiiprojekthi zokwenyani.

Yintoni eyenziwa yi-EMI kwiSiteji seServo Motor

I-EMI imele ukuphazamisana kwe-electromagnetic. Yingxolo yombane engafunekiyo. Ingahamba ngeentambo okanye emoyeni. Xa ifika eqongeni lakho, iphazamisa i-drive, i-encoder, ikhamera, okanye ii-sensors.

Isiphumo?Ukuphazamiseka kolawulo lwentshukumo. Iqonga alihambi kanye apho ubulixelele khona. Ngamanye amaxesha liyimpazamo encinci. Ngamanye amaxesha liyimpazamo enkulu. Kwi-optical alignment, nempazamo encinci iyinto enkulu.

Sibone inqanaba eliqhelekileyo elinokuphindaphinda kwe-2 µm kwilebhu. Kumgca wokuvelisa, lehle laya kwi-15 µm. Inqanaba elifanayo. Umatshini ofanayo. Umahluko kuphela yayiyi-EMI kwizixhobo ezikufutshane.

Apho i-EMI ivela khona kwiinqanaba zeemoto

I-EMI kwizigaba zeemotoidla ngokuvela kwiindawo ezine. Masizihlalutye.

I-Drive idla ngokuba yi-Main Slaughter

Uninzi lwee-servo drives zisebenzisa i-PWM. Oko kuthetha ukuba zivula kwaye zicima umbane ngokukhawuleza kakhulu. Sithetha nge-10 kHz ukuya kwi-100 kHz nangaphezulu. Olu tshintsho lukhawulezayo ludala ingxolo ephezulu. Ngumthombo omkhulu we-EMI kwiinkqubo ezininzi.

Iintambo kunye nokuGxila: Abarhanelwa abaQhelekileyo

Iintambo zombane kunye neentambo zesiginali akufuneki zisebenze kunye. Ukuba ziyasebenza, ingxolo iyatsiba ukusuka kwenye iye kwenye. Sibone intambo ye-encoder engagqunywanga eneemitha ezi-3 ibaleka ecaleni kwentambo yombane ye-220 V. Oko kongeze i-10 µm yempazamo. Kusuka nje ekuqondiseni intambo.

Umhlaba ongalunganga ngowomnye omkhulu. I-ground loop isebenza njenge-antenna. Ibamba ingxolo ize iyithumele ngqo kwi-encoder okanye kwikhamera yakho.

Iikhowudi kunye neeKhamera zizinto ezibangela le ngxaki

Ii-encoders zithumela imiqondiso ye-voltage ephantsi. Kulula ukuziphazamisa. Ukuba intambo ye-encoder ayikhuselekanga, ingxolo inokutshintsha ii-pulses. I-drive ke icinga ukuba iqonga likwindawo engeyiyo.

Iikhamera nazo zinobuthathaka. I-EMI ibonakala njengemigca, ikhephu, okanye iibha eziqengqelekayo kumfanekiso. Isoftware ibona umda ongalunganga. Ibala umda ongalunganga. Iqonga lihamba liye kwindawo engalunganga.

Eminye Imithombo Ongenakuyicinga Ngayo

IiWelders, iipompo, iileser, kwanezibane zefluorescent zinokwenza i-EMI. Sakha saba nomthengi owayenesiphako seqonga rhoqo xa i-welder ekufutshane ivula. Iqonga lalilungile. Ingxaki yayikukusingqongileyo.

Kutheni Ukulungelelaniswa Kwe-Optical Okuzenzakalelayo Kunobuthathaka Kangaka?

I-EMI kwiZigaba zeeMoto zeePlatforms zoLungelelaniso lwe-Optical oluZenzekelayoyingxaki eqhelekileyo nebiza kakhulu. Nantsi isizathu.

Ulungelelwaniso lwe-Optical yinkqubo evaliweyo. Ikhamera ijonga uphawu. Isoftware ibala i-offset. Inqanaba liyahamba ukuze lilungiswe. Emva koko ikhamera iyajonga kwakhona. Ukuba i-EMI ingena kwisignali yekhamera, umfanekiso awucaci. Ukuba i-EMI ingena kwisignali ye-encoder, idrayivu iyabhideka. I-loop ayihlali.

Kwimizi-mveliso emininzi, injongo yi-1 µm ukuya kwi-5 µm. I-EMI inokongeza ngokulula i-10 µm ukuya kwi-50 µm yempazamo. Nguwo lowo umahluko phakathi kokudlula nokungaphumeleli.
