Ua hauj lwm hauv paus ntsiab lus daim duab ntawm decelerating stepper motor thiab teeb meem xav tau kev saib xyuas

Qhov loj tshaj qhov sib txawv ntawm lub decelerated stepper lub cev muaj zog thiab lwm yam kev tswj lub cev muaj zog yog tias nws tau txais cov digital tswj teeb liab hluav taws xob pulse teeb liab thiab hloov nws mus rau hauv qhov sib thooj angular displacement los yog linear displacement. Nws nws tus kheej yog cov thawj coj uas ua tiav cov kev hloov pauv digital, thiab nws tuaj yeem qhib-voj txoj haujlwm tswj, nkag mus rau lub teeb liab mem tes kom tau txais txoj haujlwm nce ntxiv, xws li hu ua incremental position control system yog piv nrog cov tsoos DC tswj system. , Tus nqi txo qis, thiab kev hloov kho system yuav luag tsis tsim nyog.

Keeb kwm ntawm lub deceleration stepper lub cev muaj zog: Xyoo 1973, Lub Tuam Txhab Baigla tau tsim cov theem tsis muaj hybrid stepper lub cev muaj zog thiab nws cov neeg tsav tsheb. Xyoo 1993, nws tau qhia peb-theem hybrid stepper lub cev muaj zog nrog kev ua tau zoo dua. Ua ntej xyoo 1980s hauv peb lub teb chaws, lub cev muaj zog reactive yeej ib txwm muaj qhov tseem ceeb, thiab hybrid stepper motor tsuas yog pib tsim thaum xyoo 1980s.

Cov teeb meem xav tau kev saib xyuas hauv kev siv tiag tiag ntawm decelerating stepper motor:

1. Lub hauv paus ntsiab lus ntawm kev xaiv lub cev muaj zog ua ntej thiab tom qab ntawd tus tsav yuav tsum ua raws li;

2. Rau kev thauj khoom nrog lub sijhawm loj ntawm inertia, yuav tsum xaiv lub tshuab loj loj loj;

3. Nws yog qhov zoo dua tsis siv lub xeev tag nrho rau cov kauj ruam lub cev muaj zog, thiab kev vibration yog loj nyob rau hauv lub xeev tag nrho; lub cev muaj zog ua haujlwm qis dua 90 RPM thiab yuav tsum tau tsav los ntawm qhov me me tam sim no, inductance loj, thiab tsis tshua muaj hluav taws xob;

4. Lub stepping lub cev muaj zog yog siv nyob rau hauv tsawg-ceev zaus-qhov ceev tsis tshaj 1000 revolutions ib feeb, thiab nws yog qhov zoo tshaj plaws los siv ntawm 150-450RPM. Nws tuaj yeem siv tau ntawm no los ntawm kev siv lub tshuab deceleration. Lub sijhawm no, lub cev muaj zog muaj kev ua haujlwm siab thiab tsis muaj suab nrov;

5. Vim keeb kwm yog vim li cas, tsuas yog lub cev muaj zog nrog lub nominal voltage ntawm 12V siv 12V, thiab tus nqi voltage ntawm lwm cov motors tsis yog tus tsav tsheb voltage volt nqi. Kev tsav tsheb voltage tuaj yeem xaiv raws li tus neeg tsav tsheb (lub tuam txhab stepping motor pom zoo: 42 lub cev muaj zog siv DC 12V-24V, 57 lub cev muaj zog siv DC 24-36V). Tau kawg, 12V voltage kuj tseem tuaj yeem tsav los ntawm lwm lub zog tsav tsheb dhau li ntawm 12V qhov hluav taws xob tas li, tab sis qhov kub thiab txias yuav tsum tau txiav txim siab.

6. Rau siab precision, nws yuav tsum tau daws los ntawm mechanically decelerating, nce lub ceev ntawm lub cev muaj zog, los yog siv ib tug tsav tsheb nrog ib tug high subdivision tooj. Lub cev muaj zog 5-theem kuj tseem siv tau.

7. Lub cev muaj zog yuav tsum tsis txhob ua haujlwm hauv qhov chaw vibration. Yog tias tsim nyog, nws tuaj yeem daws tau los ntawm kev hloov qhov voltage, tam sim no lossis ntxiv qee qhov damping.

8. Thaum lub cev muaj zog yog nyob rau hauv ib tug kuj high-speed los yog loj inertia load, nws yog feem ntau tsis pib ntawm kev ua hauj lwm ceev, tab sis siv ib tug gradual nce nyob rau hauv zaus kom ceev, thawj, lub cev muaj zog tsis poob kauj ruam, thiab thib ob. , nws tuaj yeem txo cov suab nrov thiab txhim kho qhov tseeb ntawm qhov chaw nres tsheb.
