Lub Underrated Dub Technology Dab tsi ua rau Coreless lub cev muaj zog thiaj li Agile rau Humanoid Robots?

Thaum koj xav txog cov motors, cov neeg feem coob pom ib qho hnyav ntawm tooj liab thiab hlau. Niaj hnub no, peb tab tom tham txog tsis yog ib qho "outlier hauv lub ntiaj teb lub cev muaj zog," tab sis kuj yog tus ntsuj plig ntawm humanoid robots - lub cev tsis muaj zog.

Vim li cas nws thiaj li tau txais kev saib xyuas ntau los ntawm tech bloggers thiab cov thawj coj khoom? Cia wb mus saib ntxiv.

I. Nws Yog Dab Tsi? Cia peb pib nrog "Tsis Muaj Hlau Core"

Structurely, ib tug raug DC lub cev muaj zog muaj ib tug tuab hlau core nyob rau hauv nws rotor, ntom ntom ntom nrog tooj liab coils, muab nws ib tug zoo tsos. Lub cev tsis muaj zog, txawm li cas los xij, tag nrho tso tseg cov tub ntxhais hlau. Nws lub rotor yog ua los ntawm cov hlau qhov txhab ncaj qha mus rau hauv lub hollow, nyias -walled cylindrical kauj, zoo li lub khob dej.

Qhov kev sib txawv yooj yim no ua rau muaj kev hloov pauv hloov pauv hauv kev ua haujlwm.

Vim tias cov tub ntxhais hlau raug tshem tawm, qhov teeb meem feem ntau "hlau poob" hauv cov tsoos motors - lub zog poob los ntawm eddy tam sim no thiab hysteresis cuam tshuam - yog tag nrho. Qhov no zoo li tshem tawm qhov hnyav tshaj plaws ntawm lub cav tsheb, lub flywheel; lub teeb ncej rotates, txo cov tsis kam thiab ib txwm nce efficiency.

II. Tsib Core Advantages uas Outperform Traditional Motors

Tau nkag siab lub ntsiab cai, cia saib nws qhov zoo. Nyob rau hauv lub tshav pob ntawm precision kis tau tus mob, coreless motors, nrog lawv cov high zog ceev ceev, ceev teb, thiab superior efficiency, yog nce los ua lub tseem ceeb hwj chim xaiv rau advanced daim ntaub ntawv. Tshwj xeeb, nws qhov zoo yog qhov tseem ceeb hauv tsib lub ntsiab lus hauv qab no:

1. Zog-txuag thiab ua tau zoo heev, pom lub zog txuag

Yog tsis muaj hlau poob, ua ke nrog lub compact magnetic Circuit Court tsim, lub zog conversion efficiency yuav ncav cuag 70% mus rau 90%, thaum tsoos hlau - cov tub ntxhais motors feem ntau tsuas ua tau ib ncig ntawm 70%. Rau cov khoom siv nqa tau yooj yim thiab dav hlau uas tso siab rau lub roj teeb lub zog, tib lub zog hluav taws xob tuaj yeem txuas ntxiv lub sijhawm ya davhlau.

2. Millisecond-Kev teb theem, nrawm heev koj tsis tuaj yeem hnov ​​​​qab

Teb ceev yog lub coreless lub cev muaj zog qhov zoo tshaj plaws feature. Vim tias lub rotor tsis muaj qhov hnyav thiab muaj lub sijhawm tsis txaus ntawm inertia, nws lub sijhawm siv tshuab tsis tu ncua yog feem ntau tsawg dua 28 milliseconds, nrog rau qee cov khoom saum toj kawg nkaus -tier txawm tias ua tiav tsawg dua 10 milliseconds. Piv txwv li, cov hlau tsoos - cov tub ntxhais motors feem ntau xav tau ntau tshaj 100 milliseconds. Qhov no txhais tau tias nws tuaj yeem pib thiab nres tam sim ntawd, zoo li lub tsheb sib tw F1, uas yog qhov tseem ceeb heev rau cov xwm txheej uas yuav tsum tau teb tam sim ntawd, xws li kev hloov kho cuaj luaj tis thiab lub koob yees duab autofocus.

3. Muaj zog ceev ceev, lub zog loj hauv ib qho me me

Vim nws cov hlau -core-tsim tsim tsawg, qhov ntim thiab qhov hnyav ntawm lub cev tsis muaj zog tuaj yeem raug txo los ntawm kwv yees li 1/3 txog 1/2 rau tib lub zog tso zis. Rau cov khoom siv nrog qhov chaw tsawg heev, qhov no yog qhov tseeb ntawm lub zog tseem ceeb uas lawv tau npau suav txog.

4. Kev ua haujlwm du thiab du, yuav luag tsis muaj jerking

Ib txwm hlau- cov tub ntxhais lub cev muaj zog feem ntau muaj kev sib tw thiab kev xav tsis zoo ntawm qhov nrawm vim yog qhov sib nqus ntawm cov tub ntxhais hlau (cov nyhuv cogging). Coreless motors lub cev tshem tawm qhov kev cog lus no, ua rau muaj kev ua haujlwm zoo heev, qis suab nrov, thiab cuam tshuam electromagnetic tsawg.

5. Precise Control, Lub hom phiaj ua tiav

Nws qhov kev hloov pauv ceev tuaj yeem tswj tau yooj yim hauv 2%, thiab ua ke nrog lub siab - kev daws teeb meem encoder, nws tuaj yeem ua tiav txoj haujlwm meej heev thiab tswj ceev. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov khoom siv nrog kev tswj xyuas nruj, xws li kev phais neeg hlau thiab bionic prosthetics.

III. Brushed vs. Brushless: Yuav Xaiv qhov twg?

Thaum coreless motors hla cov tub ntxhais hlau, lawv tseem poob rau hauv pawg "brushed" thiab "brushless," uas txawv heev hauv cov qauv thiab cov neeg siv kev paub.

Lub rotor ntawm lub cev tsis muaj zog yog qhov tsuas yog cov coreless coil, siv lub cev txhuam hniav thiab lub commutator los hloov cov kev taw qhia tam sim no. Nws qhov zoo muaj xws li kev tswj xyuas yooj yim, tus nqi qis, thiab tus nqi qis dua. Txawm li cas los xij, kev lag luam tawm - tawm suav nrog kev sib txhuam tsim hluav taws xob thiab hnav, lub neej luv dua (kwv yees li 1000 txog 3000 teev), thiab lub peev xwm rau hluav taws xob cuam tshuam cuam tshuam nrog cov khoom siv hluav taws xob nyob ib puag ncig. Nws yog qhov tsim nyog rau tus nqi- cov khoom siv rhiab heev nrog kev ua haujlwm tsawg zaus lossis luv luv - siv sijhawm.

Lub brushless coreless lub cev muaj zog yog qhov rov qab - lub kauj yog tsau, thiab cov hlau nplaum ruaj khov ua raws li lub rotor tig. Nws pom txoj haujlwm siv Hall effect sensors thiab ua tiav kev sib hloov nrog lub tshuab hluav taws xob, tshem tawm tag nrho lub cev kev sib txhuam. Qhov no txuas ntxiv nws lub neej ntev mus rau ntau dua 10,000 teev, nce nws qhov ceev tshaj plaws (nyob ib ncig ntawm 15,000 rpm hauv qab tsis muaj-load), thiab ua rau muaj kev ua haujlwm ntsiag to thiab tsis tshua muaj hluav taws xob cuam tshuam. Lub downside yog nws cov qauv complex, xav tau ib tug tshwj xeeb lub cev muaj zog tsav tsheb, uas ua rau kom nws cov nqi. Nws yog lub sijhawm ntev - ua haujlwm tau zoo hauv cov khoom siv siab - kawg, haum rau cov ntawv thov uas xav tau ntev - lub sijhawm ua haujlwm ruaj khov.

IV. Los ntawm Fingertips mus rau qhov chaw: Coreless Motors nyob txhua qhov chaw
Daim ntawv thov scenarios rau coreless motors yog dav heev, xws li los ntawm siab -kawg tub rog technology mus rau cov neeg siv khoom siv hluav taws xob niaj hnub:

Robots, tshwj xeeb tshaj yog humanoid robots, yog "kua ntawm txhua tus neeg lub qhov muag": Qhov no yog ib qho ntawm cov neeg saib ntau tshaj plaws nyob rau xyoo tas los no. Tesla's Optimus robots dexterous txhais tes siv classic rau - lub tswv yim tsav tsheb nrog 11 degrees ntawm txoj kev ywj pheej, yooj yim ua tau yooj yim txav xws li tuav thiab nqa. Nws yog precisely lub coreless lub cev muaj peev xwm ua tau siab precision thiab siab zog ceev nyob rau hauv ib tug me me me me uas ua rau cov neeg hlau lub ntsis ntiv tes hloov tau.

Aerospace thiab Tub Rog: Hauv cov xwm txheej xav tau xws li kev hloov pauv huab cua huab cua, drone rotor tsav, thiab kev tswj hwm tus cwj pwm satellite, lub cev tsis muaj zog, nrog nws lub teeb yuag thiab kev ua haujlwm siab, pab txo qhov hnyav ntawm lub dav hlau los ntawm txhua gram.

Kev kho mob thiab kev noj qab haus huv: Hauv cov cuab yeej phais mob tsawg kawg nkaus, endoscopes, cov cuab yeej kho hniav, thiab bionic prostheses, nws muab kev ruaj khov, meej, thiab kev co- tawm hluav taws xob pub dawb, cuam tshuam ncaj qha rau kev nyab xeeb thiab kev ua haujlwm ntawm kev phais.

High-End Consumer Electronics thiab Smart Home: Cov khoom me me no tseem muaj zog "lub siab" tau muab zais rau hauv qhov siab - zaus kev co ntawm cov txhuam hniav hluav taws xob, lub autofocus ntawm VR tsom iav, lub zog muaj zog ntawm siab -kawg plaub hau tshuab, thiab txawm tias lub qhov rooj ntse thiab cov cuab yeej siv fais fab.
