Txhuam tsav tsis ntseeg: dab tsi koj yuav tsum paub txog cov motors no

Lub cev muaj zog tsis txhuam

Koj twb hnov ​​ntawm lub lub cev muaj zog brushlessCov. Nws yog ib qho ib txwm pom lub sij hawm no hauv ntau cov khoom piav qhia. Piv txwv li, hauv drones koj tuaj yeem pom tias ntau tus neeg muaj lub zog hluav taws xob no. Qhov tseeb, qee cov tuam ntxhab siv nws ua kev thov rau cov neeg siv khoom zoo, vim lawv muaj lawv qhov zoo.

Tab sis dab tsi no brushless lub cev muaj zog? Dab tsi sib txawv muaj nyob nrog kev hwm lwm hom DC motorsCov. Zoo tag nrho cov xav tsis thoob thiab ntau kuv yuav sim qhia kom meej rau lawv hauv tsab xov xwm no ...

Xws li lwm yam Hluav taws xob Cheebtsam, cov cav no tuaj yeem muab khi tau zoo nrog koj cov haujlwm DIY nrog lub rooj tsavxwm arduino thiab lwm tus

Dab tsi yog txhuam lub cev muaj zog?

Un lub cev muaj zog txhuam, lossis lub cev muaj zog brushless, Nws yog lub cev hluav taws xob li qub thiab tam sim no, tab sis nws tsis siv txhuam txhuam los hloov lub polarity ntawm lub cev muaj zog. Qhov no zam dhau qee qhov teeb meem kev ua haujlwm thiab tiv thaiv lawv los ntawm qhov yuav tsum tau hloov. Tias yog vim li cas nws yog siv raws li kev thov nyiaj, txawm hais tias nws yog qhov tseeb hais tias nws yog qhov sib tw ua dog dig, vim tias feem ntau cov tsheb tam sim no feem ntau tsis txhuam.

lub lub tshuab hluav taws xob qub Yog lawm lawv siv cov txhuam hom no, qee cov ntsiab lus uas txhuam thiab yog li txo kev ua haujlwm ntawm lub cev muaj zog los ntawm kev sib txhuam, ua kom muaj qhov kub siab dua, hnav, suab nrov, thiab xav tau kev txij nkawm no yuav tsum ntxuav cov pa roj carbon hmoov uas tsim tawm hauv lub cev muaj zog (uas tuaj yeem tsis tsuas yog cuam tshuam kev ua haujlwm, nws tseem tuaj yeem ua tus coj thiab ua rau muaj teeb meem hluav taws xob) thiab hloov cov txhuam hniav hnav.

Tias yog vim li cas thiaj li ua ntej lub cav txhuam hniav tau tsim. Thawj zaug hauv daim teb asynchronous AC lub cev muaj zog, thiab tom qab ntawd ua lub lev mus rau lwm qhov motors xws li DC, uas yog qhov uas peb nyiam tshaj plaws hauv blog no.

Txawm hais tias thaum pib lawv yog cov tshiab thiab kim dua Los ua cov khoom lag luam, kev nce qib ntawm cov thev naus laus zis thiab khoom siv hluav taws xob tau ua rau nws tam sim no los tsim lawv kev lag luam. Txawm li cas los xij, nws txoj kev tswj hwm tuaj yeem yog me ntsis ntau dua. Txawm hais tias ESC cov tswj ceev tau tshem cov teeb meem no ...

Tam sim no, AC motors tam sim no nyob rau hauv ntau pab ua ke nyeg thiab kev lag luam, nrog rau tsheb, thiab lwm yam. Raws li rau CCs, koj tseem tuaj yeem nrhiav lawv hauv kev nyeem ntawv kho qhov muag disc, khoos phis tawj kiv cua, drones, robots, thiab lwm yam ntev.

Ntu ntawm cov maus taus txhuam thiab kev ua haujlwm

Qhov tseeb yog qhov ntawd ntawm qhov ntawm brushless lub cev muaj zog yog yooj yim heev. Nrog lub ntsuas hluav taws xob nrog cov sib nqus cov sib nqus piav qhia hauv cov kab lus ntawm lub tshuab hluav taws xob, thiab lub rotor uas yuav tig vim qhov kev xav ntawm lub sib nqus.

Tab sis txoj hauv kev los qhib lawv tau yog nws txawv me ntsis los ntawm lwm tus txhuam hniav AC thiab DC lub cev muaj zog. Txawm li cas los xij, ntau lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab cov yam ntxwv yuav zoo ib yam.

Ua kom yooj yim dua, tus ESC (Cov Hluav Taws Xob Hluav Taws Xob), uas yog, kev tswj hwm kom muaj peev xwm hloov qhov polarity ntawm windings ntawm lub zog brusnce lub cev muaj zog los tswj txoj kev sib hloov. Lawv tso cai yooj yim los ntawm PWM, nrog microcontrollers zoo li ib ntawm Arduino board.

ESC cov qauv muaj cov khoom siv hluav taws xob uas muaj peev xwm ntawm lub cev muaj zog yam tsis ua teeb meem rau cov neeg siv ntau dhau. Nyob ntawm hom ntawm lub cav thiab lub zog koj yuav xav tau ib hom lossis lwm hom ntawm neeg tsav tsheb, raws li peb twb tau txheeb xyuas hauv lwm cov ntawv.

Nco ntsoov tias koj tuaj yeem siv tau MOSFET transistors saib xyuas nws yog tias koj tsis muaj ib qho qauv ntawm cov no. Yeej tus neeg tsav tsheb lossis ESC yog qhov Circuit Court uas tso cai rau hloov txoj kev hloov pauv ntawm cov transistors los hloov lub zog mov polarity ntawm lub cev muaj zog ua tsaug rau cov transistors uas sau nws.

Zoo

Entre qhov zoo cov ntsiab lus tseem ceeb ntawm lub cev muaj zog:

  • Ua kom zoo dua-torque piv. Yog li ntawd, koj tuaj yeem rub tawm ntau cov kev ua tau zoo los ntawm lawv.
  • Teb zoo dua cov lus teb.
  • Kev siv hluav taws xob ntau, kom txuag tau lub zog. Qhov tshwj xeeb tseem ceeb hauv cov roj teeb uas siv hluav taws xob.
  • Tsawg tshaj cua sov. Tsis tas siv lub tshuab hluav taws xob ntxiv lossis hnav zoo heev.
  • Ntau ruaj, raws li nws tsis xav tau kev txij nkawm ntau dhau los, tsis yog nws muaj kev txhuam lossis hnav.
  • Suab nrov. Lawv muaj ntau yam nyob ntsiag to los ntawm tsis chwv ib yam dabtsi.
  • Tus nqi siab dua, zoo tagnrho rau cov ntawv thov uas nws qhov tseem ceeb, xws li kev sib tw drones.
  • Kev cog lus ntawm Txawm hais tias lub zog uas lawv muaj, lawv tseem ntau dua lwm qhov sib txig sib luag dua li tus txhuam hniav.
  • Yog tsis muaj kev tu. Koj yuav tsis muaj inopportune nres vim los ntawm kev coj ntawm txhuam, los yog yuav khoom seem, ntxuav cov hmoov av tsim, thiab lwm yam.

Disadvantages

Yog lawm, kev siv lub tshuab txhuam tsis zoo yuav tsis txhua yam. Lawv muaj lawv cov menyuam me tsis zoo:

  • Tus nqi them, nws yog me ntsis siab dua tus txhuam hniav. Txawm li cas los xij, thev naus laus zis tam sim no txhais tau hais tias koj tuaj yeem yuav lub cev muaj hluav taws xob ntawm tus nqi zoo.
  • Txhawm rau tswj nws, koj yuav tsum muaj cov tsav tsheb lossis cov tswj kom koj tuaj yeem tswj tau qhov kev sib hloov. Nws tsis tuaj yeem ua nws manually li lwm yam.

Dua li ntawm, lawv yog cove tau yuam txoj kev lag luam no thiab nws ua rau nws tsim nyog xaiv ib qho ntawm lawv ...
