Stepper tsav siv kev paub
Feem ntau ntsib teeb meem thaum siv stepper motors ---- kauj ruam poob lawm.
Peb tus kws kho tsheb siv cov cav ntoo kom siv tau ntau xyoo, cov neeg tsav tsheb ua tsis tau xav txog kev phem, tshwj tsis yog tus neeg tsav tsheb stepper tsis tsim nyog.
Vim hais tias muaj kev siv zoo ntawm kev ua tiav kev tsav tsheb, yog li cov kev pabcuam qeeb tsis yooj yim rau kuv, stepper motor muaj qhov kom zoo dua cov kev qhia yooj yooj yim, thaiv tsawg dua, tsawg dua txhaum, loj torque, thiab tam sim no lub theem qis motor pulses mus txog 60000 PUL / REV, qhov tseeb txaus.Paub yuav ncav cuag 3000 rpm, feem ntau yuav ncav cuag 600 rpm. Stepper tsav feem ntau hais tias yuav tau mus cuag 600 rpm, qhov tseeb, tsis tau mus txog qhov ceev, manufacturers hais tias 600 rpm, nws yog qhov zoo yog tias tau txais 500RPM thaum khiav. Txawm li cas los, lub tshuab yuav mus 500 rpm, nws yog sai heev.Yog tshaj 500RPM, tej zaum yuav stalled, lub cev ua suab nrov zoo li ib daig, uas yog tus ceev heev, thiab lub cav tsis tuaj yeem ua haujlwm.Cov tshwm sim ntawm no phenomenon, kua yog: 1, los txo cov kev khiav haujlwm ntau zaus ; 2, loj dua qhov nce thiab txo lub sij hawm siv acceleration ; 3, txo cov zaus pib; 4, kho cov micro-theem kom siab.
Stepper motor ceev thiab torque inversely proportional, kom ceev rotation, lub me torque.Qhov no tseem ceeb heev nyob rau hauv qhov kev xaiv, tsis yog ib tug me nees rub lub laub loj.Nws tsis xaiv ib lub cav loj, me me los yog txaus yog tsis zoo, kauj ruam poob los ntawm lub cav me me, hnyav hnyav.
Feem ntau, lub teeb liab plhaw yog 24V txoj hlua 2K ua hauj.Dua li ntawm cov tshuaj feem ntau pom zoo los ntawm 1.8K ~ 2K. Qhov tseeb, kuv ntsuas, 2K ua hauj, lub pulse voltage no xwb 2.2V.Later kuv siv 1.5K ua hauj.Yog qhov teeb meem yog tias kuv tuaj mus xyaum, muaj ib lub cev tsis mus du, kos ntau qhov chaw thiab tsis pom tias yog vim li cas, ces hloov kev ntseeg, nws yog qhov zoo. Feem ntau, optocoupler tuaj yeem tiv thaiv 24V, tshwj xeeb yog tsis muaj kev ua haujlwm, los kuj siv tau ncaj qha. Ntawm chav kawm, nws yog zoo dua rau nruab ib resistor.
Muaj ntau tus neeg hais tias cov kauj ruam ua kauj ruam poob, qhov tseeb, muaj ntau yam khoom siv, cov hlua fais fab tsis tau zoo dua, cov ciav hlau, cov ciav hlau, txhua yam teeb meem tuaj yeem ua rau tsis yog txhua yam teeb meem, thiab qhov pib hloov zoo, ncaj qha rau qhov tseeb.
Kuv tau ntsib lawv tus kheej cov txheej txheem kom muaj txoj hauj lwm sib ntaus, tej zaum ib qho teeb meem kev nyuaj, uas yog, tom qab ua tiav tiav, qhov kev zov me nyuam qee zaus khiav qhov kev zov me nyuam rov qab qub txoj haujlwm, hom kev pab cuam tsis txuas nrog. Qhov no ncaj qha los ntawm kev ua yuam kev, tom qab saib xyuas ntev ntev kom paub qhov teeb meem no . Saib ntau cov ncauj lus txog kev txhim kho kev ua yuam kev, kuv xav tias muaj ntau yam ua tau raws li kuv tau ntsib.
Stepper motor tsim inertia li loj load, qhov teeb meem tshwm sim los ntawm tsiv deb dhau.
Jogging cov lus qhia tsis muaj tseeb, tshwj xeeb tshaj yog nrog rau qhov taw tes rau kev khiav rov qab mus rau lub hauv paus chiv keeb, nws tsis yog lawm. Tshaj thiab nres ntawm jogging yog tiav 90 degrees cai, pib thiab nres sib npaug zos rau lub tsho nres.Tsis keeb kwm tseem yuav tsum siv homing cov lus qhia.
Tam sim no tus cav stepper motor yuav tsum tsis txhob muaj teeb tsa tam sim no, feem ntau me me, rated 6A, kho rau 5.5A. Lub sijhawm no lub tawb txaus, qhov kub siab yuav siab. Txawm hais tias lub cav xaib tuaj yeem ncav 80 degrees, qhov kub siab dhau, yuav cuam tshuam rau magnetic teb.
