Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm brushless stepper motors thiab brushed motors?

1. Lub ntsiab zoo thiab qhov tsis zoo ntawm brushless thiab brushed motors:

1. Lub ntsiab zoo ntawm brushless motors yog:

Ua ntej, kev pab cuam lub neej ntawm brushless motors yog ntev: vim hais tias brushless motors siv controllers es tsis txhob ntawm commutators thiab carbon txhuam, lawv yog ob peb zaug los yog txawm kaum ob lub sij hawm ntawm brushed motors. Lub neej ntawm cov txhuam hniav yog txwv. Piv txwv li, cov txhuam hniav yuav raug hnav tom qab ib txhiab teev thiab tuaj yeem hloov cov txhuam hniav lossis lub cev muaj zog.

Qhov thib ob, kev khiav ceev ntawm brushless motors yog siab: brushless motors siv magnetic teb induction, tsis muaj kev sib cuag, thiab kev khiav ceev yuav ceev dua.

Thib peb, lub suab nrov ntawm lub cev tsis muaj zog yog qhov tsawg: nws yog qhov tsim nyog rau qee qhov chaw uas yuav tsum tau nyob ntsiag to, xws li tsev kho mob, tsev txhab nyiaj, tshav dav hlau, tsev kawm ntawv, thiab lwm yam, qhov twg yuav tsum tau ua kom ntsiag to thiab txo suab nrov.

Plaub, tsis muaj lub txim taws thaum lub tshuab tsis siv lub tshuab ua haujlwm: brushless motors tuaj yeem muaj txiaj ntsig zoo hauv qee lub sijhawm, feem ntau haum rau qee qhov chaw tawg thiab tawg, txhawm rau txhim kho kev nyab xeeb.

2. Lub ntsiab tsis zoo ntawm brushless motors yog:

Ua ntej, tus nqi ntawm brushless motors yog siab: tus nqi ntawm controllers nce los ntawm tsawg kawg yog 100 yuan rau micro motors. Tus thawj commutator thiab carbon txhuam tus nqi qis dua.
Qhov thib ob, kev siv ib puag ncig ntawm brushless motors raug txwv: yog tias ib puag ncig uas siv lub tshuab brushless yog nyob rau hauv lub siab magnetic teb los yog tau nyob rau hauv kev sib cuag nrog los yog nyob ze heev rau ib tug siab magnetic teb, lub brushless lub cev muaj zog yuav poob nws cov hauj lwm. Qhov no feem ntau yog vim lub rotor tivthaiv ntawm lub brushless lub cev muaj zog nws tus kheej yog ua los ntawm hlau nplaum, uas yog sib nqus tsuas yog tom qab magnetization. Yog tias nws tau nruab rau hauv qhov chaw sib nqus siab lossis ze rau qhov chaw sib nqus siab, nws yuav hloov pauv qhov sib nqus ntawm lub rotor lossis tshem tawm ib feem ntawm cov hlau nplaum, thiab lub cev tsis muaj zog yuav tsis ua haujlwm zoo lossis ua haujlwm tsis zoo.
3. Lub ntsiab zoo ntawm brushed motors yog:
Ua ntej, siab tswj qhov tseeb: txhuam cov motors feem ntau yog siv nrog txo cov thawv thiab cov decoders kom lub cev muaj zog tso zis ntau dua thiab kev tswj xyuas qhov tseeb dua. Kev tswj qhov tseeb tuaj yeem ncav cuag 0.01 hli, thiab cov khoom txav tuaj yeem yuav luag nres ntawm txhua qhov chaw xav tau. Tag nrho cov cuab yeej siv tshuab precision siv DC lub cev muaj zog tswj qhov tseeb.
Qhov thib ob, cov qauv yooj yim: brushed motors muaj cov qauv yooj yim, yooj yim ntau lawm thiab ua, yooj yim txij nkawm, thiab tswj tau yooj yim; DC motors kuj muaj cov lus teb ceev ceev, loj pib torque, thiab muaj peev xwm muab rated torque los ntawm xoom ceev mus rau rated ceev.
Thib peb, kev ua haujlwm du, zoo pib thiab nres cuam tshuam: Txhuam lub cev muaj zog yog tswj los ntawm kev tswj hluav taws xob, yog li pib thiab nres yog du, thiab lawv kuj yog du thaum khiav ntawm qhov ceev tsis tu ncua. Brushless motors feem ntau yog digital zaus hloov pauv tswj, uas thawj zaug hloov AC rau DC, thiab tom qab ntawd DC rau AC, thiab tswj qhov nrawm los ntawm kev hloov pauv zaus. Yog li ntawd, brushless motors tsis khiav zoo thaum pib thiab braking, thiab vibrate heev. Lawv tsuas yog khiav tau yooj yim thaum qhov ceev tsis tu ncua.
4. Lub ntsiab qhov tsis zoo ntawm txhuam cov motors yog:
Ua ntej, kev sib txhuam ntawm cov txhuam hniav thiab cov commutator yuav ua rau sparks thiab cuam tshuam loj heev.
Thib ob, vim tias qhov kev tiv thaiv loj, qhov ua tau zoo yog qhov tsawg thiab cov zis hluav taws xob tsawg.
Thib peb, kev saib xyuas yog teeb meem, thiab cov txhuam hniav yuav tsum tau hloov tas li.
Plaub, muaj kev sib txhuam ntawm cov txhuam hniav thiab cov commutator, uas ua rau txo qis kev ua haujlwm, muaj suab nrov, thiab tsim kom muaj cua sov yooj yim. Lub neej ntawm lub cev muaj zog yog ob peb zaug luv dua li ntawm lub cev tsis muaj zog.
