Drone motors ua haujlwm li cas? DC los yog AC?
Tso lus
Taw qhia: "Lub zog qhov chaw" ntawm drones
Nrog rau txoj kev loj hlob ntawm kev lag luam qis qis, cov drones tau txav los ntawm cov khoom ua si rau cov neeg nyiam mus rau cov cuab yeej tseem ceeb rau kev siv kev tshaj lij. Lawv ya hla teb ua liaj ua teb los tua tshuaj tua kab; lawv taug kev los ntawm cov nroog kom xa cov khoom xa tuaj sai; lawv mus tob rau hauv cov mines, hav zoov, thiab thaj chaw muaj kev puas tsuaj, ua haujlwm ntau thiab ntau dua kev lag luam thiab pej xeem.
Tom qab tag nrho cov no, muaj lub zog tseem ceeb uas txiav txim siab qhov ua tau zoo, kev ruaj ntseg thiab lub neej ntawm lub davhlau - uas yog lub cev muaj zog. Nws tsav cov hniav kom tig ntawm kev kub ceev, muab kev nqa thiab tswj lub zog, tso cai rau lub drone tiag tiag "ya".
Yog li cas lub tshuab drone ua haujlwm li cas? Nws puas siv tam sim no ncaj qha lossis hloov tam sim no? Kab lus no yuav pib los ntawm cov hauv paus ntsiab lus, pab koj nkag siab txog kev ua haujlwm ntawm lub cev muaj zog, thiab piav qhia vim li cas yuav luag txhua tus drones xaiv brushless DC motors.
Lub hauv paus ntsiab lus ua haujlwm ntawm drone motor
Lub luag haujlwm tseem ceeb ntawm drone motors yog hloov lub zog hluav taws xob hauv lub roj teeb rau hauv lub zog hluav taws xob los tsav lub kiv cua kom tig ntawm kev kub ceev kom tsim tau nqa thiab thawb. Tam sim no, feem ntau cov drones tseem ceeb siv brushless DC motors (BLDC), uas tau siv dav hauv pej xeem thiab kev lag luam drones rau lawv cov kev ua haujlwm siab, tsis tshua muaj suab nrov, thiab cov nqi tu qis.
1. Cov qauv ntawm cov drone brushless lub cev muaj zog
Ib tug raug drone brushless lub cev muaj zog yog tsim los ntawm cov nram qab no qhov chaw:
Stator: Nws yog tsau thiab muaj peb-theem electromagnetic coils raug mob sab hauv.
Rotor: Rotates nrog electromagnetic teb thiab feem ntau yog nruab nrog cov hlau nplaum ruaj khov;
Electronic ceev tswj (ESC): Electronic ceev maub los, siv los tswj cov kev taw qhia ntawm cov dej ntws tam sim no kom ua tiav cov kev cai ceev ceev thiab pib.
2. Lub hauv paus ntsiab lus ntawm kev ua haujlwm: electromagnetic drive + hluav taws xob tswj
Kev khiav hauj lwm hauv paus ntsiab lus ntawm brushless motors yog raws li electromagnetic induction:
Lub roj teeb fais fab ESC;
Lub ESC ib ntus hloov lub zog ua ntu zus ntawm stator coils raws li lub teeb liab tswj;
Thaum lub kauj yog energized, ib tug rotating magnetic teb yog tsim, uas attracts los yog repels cov hlau nplaum mus tas li ntawm lub rotor;
Lub rotor rotates nrog lub magnetic teb, tsav lub cev muaj zog ncej thiab hniav tig, li no generating nqa;
Tag nrho cov txheej txheem tsis tas yuav tsum tau txhuam txhuam thiab tso siab rau kev tswj hluav taws xob kom ua tiav kev sib hloov, uas yog qhov ua tau zoo dua thiab tsis tshua muaj hnav.
3. Vim li cas tus qauv tsis txhuam hniav tseem ceeb?
Piv nrog cov tsoos brushed motors, brushless motors tshem tawm cov pa roj carbon txhuam thiab commutator qauv, uas coj ob peb yam tseem ceeb:
Lub neej ntev: tsis muaj cov khoom siv sib cuag, txo qis hnav;
Kev ua tau zoo dua: tsawg zog poob thiab teb sai dua;
Tsawg suab nrov: cov txheej txheem ua haujlwm yog nyob ntsiag to thiab du;
Kev saib xyuas yooj yim dua: Tsis tas yuav hloov cov txhuam hniav los yog txhuam txhuam kom huv.
Lub drone puas siv DC lub cev muaj zog lossis AC lub cev muaj zog
Qhov no yog ib lo lus nug uas ntau tus pib lossis cov neeg siv tshiab hauv kev lag luam feem ntau nug: "Puas yog lub cev muaj zog ntawm lub drone DC lossis AC?"
Cov lus teb meej: Mainstream drones siv brushless DC motors (BLDC)
Tam sim no, ntau dua 95% ntawm ntau lub rotor drones thiab tis-tis drones nyob rau hauv kev ua lag luam yog nruab nrog brushless DC motors (BLDC), ntau dua li cov tsoos AC motors (AC Motors).
Lus Cim: Qee cov khoom ua si uas tsis tshua muaj nqi thiab cov kev sim platforms kuj tseem siv cov tshuab txhuam hniav lossis lwm hom, yog li cov lus '100%' tsis siv.
Txawm hais tias lub cev muaj zog no muaj "DC" hauv nws lub npe, nws txoj kev tsav tsheb zoo li "simulated AC": nws siv DC fais fab mov (xws li roj teeb lithium) ua lub zog, thiab siv lub tshuab hluav taws xob ceev (ESC) los hloov DC fais fab mus rau peb theem tam sim no uas tau hloov ua ntu zus, yog li tsim lub rotating magnetic teb los tsav lub rotor.
Lus Cim: Txawm hais tias peb hais tias "simulated AC", lub brushless DC lub cev muaj zog (BLDC) tsis siv AC tiag. Nws siv lub tshuab hluav taws xob ceev (ESC) hloov cov kev taw qhia thiab ntu ntawm tam sim no nyob rau hauv peb txheej ntawm coils nyob rau hauv lem los ua ib tug tsis tu ncua rotating magnetic teb, yog li tsav lub rotor kom txav. Lub hwj chim qhov tseem ceeb yog DC, yog li nws tau muab cais ua "DC lub cev muaj zog".
Vim li cas ho tsis siv AC motors
Txawm hais tias AC motors (xws li induction motors thiab synchronous motors) muaj ntau heev nyob rau hauv kev lag luam scenarios, lawv tsis haum rau siv nyob rau hauv drones rau cov hauv qab no yog vim li cas:

BLDC yog qhov tsim nyog "DC daws" rau cov drones
Siv cov roj teeb ➜ Lub zog yog DC
Siv ESC ➜ Tswj logic yog digital heev
Kev ua haujlwm hom ➜ Simulate peb-theem commutation, tab sis qhov tseem ceeb tseem yog DC system
Yog li ntawd, los ntawm txoj kev siv fais fab, kev tswj txoj hauv kev rau kev siv scenario, lub brushless DC lub cev muaj zog yog undoubtedly lub feem ntau haum motor hom rau UAV davhlau platforms.
