Cov khoom ua si lub cev muaj zog yog lub tshuab hluav taws xob me me tsim tshwj xeeb rau cov khoom ua si. Nws hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob kom muaj zog rau cov khoom ua si. Ib qho khoom ua si lub cev muaj zog feem ntau muaj lub tshuab electromagnetic, lub rotor, thiab lub tsev ruaj khov. Lub zog hluav taws xob tau muab los ntawm lub cev muaj zog lub voj voog, thiab lub zog sib nqus tsim ua rau lub rotor tig, yog li tsav cov khoom ua si txav.
Cov khoom ua si motors muaj ntau hom thiab specifications, thiab tsis xws li qhov loj, lub zog, thiab ceev tuaj yeem hloov kho raws li qhov xav tau ntawm cov khoom ua si sib txawv. Lawv feem ntau yog siv hauv cov khoom ua si kom ua tiav ntau yam haujlwm xws li tsav tsheb, tig, viav vias, thiab vibrating.
1. Lub hauv paus ntsiab lus ntawm cov khoom ua si motors
Lub hauv paus ntsiab lus ua haujlwm ntawm cov khoom ua si motors yog electromagnetic induction. Thaum tam sim no dhau los ntawm lub kauj, ib qho chaw magnetic yog generated nyob ib ncig ntawm nws. Thaum lub magnetic teb cuam tshuam nrog cov hlau nplaum, lub torque yog generated, ua rau lub rotor (rotating ib feem) ntawm lub cev muaj zog pib rotating. Kev sib hloov ntawm lub rotor tsav lub tshuab ib feem ntawm cov khoom ua si kom tiav ib qho kev txiav txim.
Tshwj xeeb, cov khoom ua si lub cev muaj zog feem ntau muaj cov hauv qab no tseem ceeb:
Stator: ib qho ruaj khov, feem ntau muaj cov hlau nplaum lossis electromagnetic coil, uas ua rau muaj qhov sib nqus ruaj khov.
Rotor: ib feem rotating ua los ntawm cov khoom siv hluav taws xob. Thaum tam sim no dhau mus, lub rotor tig nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb.
Txhuam thiab commutator: Cov khoom siv no yog siv los tswj kev hloov pauv ntawm cov dej ntws tam sim no, yog li xyuas kom meej tias lub rotor ib txwm tig mus rau qhov raug.
Thaum cov tam sim no nkag mus rau hauv lub kauj los ntawm txhuam thiab commutator, lub coil tig nyob rau hauv magnetic teb ntawm stator, tsav lub rotor tig thiab tsav lub tshuab ua haujlwm.
2. Hom khoom ua si motors
Cov khoom ua si motors tau muab faib ua ob peb yam tseem ceeb raws li kev thov sib txawv thiab cov qauv tsim: DC lub cev muaj zog, stepper lub cev muaj zog, servo lub cev muaj zog, kev co lub cev muaj zog, tsis muaj lub cev muaj zog
3. Daim ntawv thov ntawm cov khoom ua si motors
1). Chaw taws teeb tswj cov khoom ua si
Cov chaw taws teeb tswj tsheb, dav hlau, nkoj, thiab lwm yam. feem ntau yog siv DC motors lossis brushless motors los tsav lub zog. Lub cev muaj zog muab cov khoom ua si no nrog lub zog tsim nyog los pab kom lawv txav mus rau pem hauv ntej, rov qab, tig, thiab lwm yam raws li cov lus qhia ntawm cov chaw taws teeb tswj.
2). Cov khoom ua si neeg hlau
Cov khoom ua si neeg hlau feem ntau xav tau kev tswj xyuas cov lus tsa suab siab, yog li siv cov motors stepper lossis servo motors. Cov motors no pab cov neeg hlau ua haujlwm nyuaj, xws li taug kev, tig, txav caj npab, thiab lwm yam. Tsis tas li ntawd, cov motors hauv cov khoom ua si neeg hlau kuj tseem siv tau nrog cov sensors thiab microcontrollers kom ua tiav cov haujlwm ntse dua.
3). Electronic tsiaj thiab cov khoom ua si simulated
Cov khoom ua si xws li cov tsiaj siv hluav taws xob thiab cov tsiaj simulated feem ntau yog siv cov vibration motors los yog DC motors me me los xyaum cov kev txav ntawm cov tsiaj tiag. Cov khoom ua si no tuaj yeem "taug kev", ua suab, co lawv cov tails los yog viav vias lawv cov ceg tawv, thiab simulate lub ntuj txav ntawm cov tsiaj los ntawm kev tsav tsheb.
4). Cov tsheb ua si thiab taug qab cov khoom ua si
Ntau lub tsheb ua si lossis cov khoom ua si taug qab kuj vam khom lub cev muaj zog kom ua tiav kev txav mus los. Piv txwv li, cov tsheb ciav hlau cov khoom ua si, khiav tsheb sib tw, thiab lwm yam. txhua yam yuav tsum muaj lub cev muaj zog los tsav kev sib hloov ntawm lub log kom lawv thiaj li khiav tau yooj yim raws txoj kev.
5). Cov khoom ua si sib tham sib
Ntau cov khoom ua si niaj hnub sib tham sib siv lub cev muaj zog los txhim kho kev sib cuam tshuam ntawm cov khoom ua si. Piv txwv li, qee cov khoom ua si menyuam roj hmab tuaj yeem ua suab, txav los yog lub ntsej muag qhia los ntawm lub cev muaj zog "sib tham" nrog cov menyuam yaus thiab txhim kho kev lom zem.
6). Cov khoom ua si sib dhos
Hauv qee cov khoom ua si sib dhos, xws li Lego lub zog hluav taws xob lossis cov khoom ua si programmable, motors yog siv los tsav cov khoom ua si ntawm cov khoom ua si lossis ua haujlwm tshwj xeeb. Stepper motors thiab servo motors feem ntau yog siv rau hauv cov khoom ua si no kom ua tiav cov tshuab ua haujlwm nyuaj.
4. Qhov zoo thiab cov kev sib tw ntawm cov khoom ua si Motors
1). Qhov zoo:
Kev ua haujlwm siab thiab kev ntseeg siab: Nrog rau kev txhim kho thev naus laus zis, kev ua haujlwm ntawm cov khoom ua si motors tau nce siab dua, thiab lawv tuaj yeem muab kev ruaj khov thiab muaj zog dua.
Me me: Cov motors feem ntau yog tsim los me me, haum rau cov khoom ua si ntawm ntau qhov ntau thiab tsawg, tsis muaj kev cuam tshuam rau cov tsos lossis yooj yim ntawm cov khoom ua si.
Adaptability: Muaj ntau ntau hom khoom ua si motors, uas tuaj yeem hloov kho raws li qhov xav tau ntawm cov khoom ua si sib txawv thiab tuaj yeem hloov mus rau ntau yam kev ua haujlwm nyuaj.
2). Kev sib tw:
Kev siv hluav taws xob: Txawm hais tias qhov ua tau zoo ntawm cov motors niaj hnub tau nce, kev siv hluav taws xob tseem yog ib qho teeb meem rau cov khoom ua si me me uas siv roj teeb. Qee lub tshuab ua haujlwm siab yuav ua rau cov khoom ua si roj teeb noj sai dua, txwv tsis pub lub sijhawm siv cov khoom ua si tas li.
Tus nqi teeb meem: Qee qhov high-end motors (xws li brushless motors thiab servo motors) yog kim thiab tej zaum yuav ua rau tus nqi tsim khoom ua si.
