Dab tsi yog cov yam ntxwv ntawm linear motors? Daim ntawv thov ntawm linear motors

Lub cev muaj zog tuaj yeem suav tau tias yog qhov deformation ntawm lub tshuab hluav taws xob hauv cov qauv. Nws tuaj yeem suav tau tias yog lub tshuab hluav taws xob hloov pauv raws nws cov kev taw qhia radial, thiab tom qab ntawd flattened thiab evolved. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob ceev ntawm kev tswj tsis siv neeg thev naus laus zis thiab microcomputers, cov kev xav tau siab dua tau muab tso rau ntawm qhov tseeb ntawm ntau yam kev tswj hwm tsis siv neeg. Cov cuab yeej ua haujlwm siab tshaj tawm txoj kev tsav tsheb yog deb ntawm kev txaus siab ntawm cov txheej txheem tswj niaj hnub no. Vim li no, ntau lub teb chaws hauv ntiaj teb tau kawm, tsim thiab siv linear motors nyob rau hauv xyoo tas los no, ua rau daim ntawv thov ntawm linear motors ntau thiab ntau dua.

Piv nrog rau lub tshuab hluav taws xob, cov kab hluav taws xob feem ntau muaj cov yam ntxwv hauv qab no: Ua ntej, cov qauv yooj yim. Vim hais tias cov kab hluav taws xob tsis tas yuav tig cov lus tsa suab mus rau hauv ib qho khoom siv ntxiv rau cov kab lus, cov qauv ntawm kev ruaj ntseg nws tus kheej yog qhov yooj yim heev, thiab qhov hnyav thiab ntim tau txo qis heev. Qhov thib ob, qhov tseeb ntawm qhov chaw yog siab. Nyob rau hauv qhov chaw uas yuav tsum tau linear tsab ntawv tsa suab, lub linear lub cev muaj peev xwm ua kom tiav qhov ncaj qha kis tau tus mob, yog li nws muaj peev xwm tshem tawm ntau yam positioning yuam kev tshwm sim los ntawm lub hauv paus kev twb kev txuas, yog li qhov chaw qhov tseeb yog siab. Qhov tseeb qhov chaw ntawm tag nrho cov kab ke hauv av trekking; qhov thib peb yog cov lus teb ceev ceev, siab yoog raws thiab kev soj ntsuam zoo. Lub cev muaj zog linear tsuas yog ua rau nws cov mover txhawb nqa los ntawm kev sib nqus levitation, yog li ntawd ib txwm muaj qhov sib txawv ntawm huab cua ntawm cov mover thiab stator yam tsis tau kov, uas tshem tawm qhov kev sib cuag ntawm stator thiab cov mover, yog li txhim kho lub zog zoo. Kev ua kom yooj yim, yooj yim thiab ua raws; Plaub, kev ua haujlwm muaj kev nyab xeeb thiab txhim khu kev qha, thiab kev pabcuam lub neej ntev. Lub cev muaj zog tuaj yeem ua tiav tsis muaj kev sib kis quab yuam, thiab kev sib txhuam ntawm cov neeg kho tshuab yuav luag xoom, yog li muaj ob peb qhov tsis xws luag thiab tsis muaj kev kho, yog li kev ua haujlwm muaj kev nyab xeeb thiab txhim khu kev qha, thiab kev pabcuam lub neej ntev.

Linear motors yog siv nyob rau hauv peb yam: ua ntej, lawv yog siv nyob rau hauv active tswj systems, thiab muaj ntau yam xws li kev siv; thib ob, lawv tau siv los ua cov tsav tsheb rau kev sib txuas ncaj qha mus ntev; Linear motion zog khoom.

——High-speed maglev tsheb ciav hlau Lub tsheb ciav hlau maglev yog qhov piv txwv zoo tshaj plaws ntawm kev siv tswv yim ntawm linear motors. Tam sim no, Tebchaws Asmeskas, Tebchaws Askiv, Nyij Pooj, Fabkis, Lub Tebchaws Yelemees, Canada thiab lwm lub tebchaws tab tom tsim cov tsheb ciav hlau linear levitation, uas Nyiv yog qhov ceev tshaj plaws.

—— Ua haujlwm of Elevator los ntawm Linear Tsav Thawj lub elevator uas tau tsav los ntawm lub cev muaj zog tau teeb tsa hauv Wanshi Building, Guam District, Tokyo, Nyiv thaum lub Plaub Hlis 1990. Lub elevator muaj qhov hnyav ntawm 600kg, qhov ceev ntawm 105m / min thiab qhov siab ntawm 22.9. m. Txij li thaum lub elevator uas tau tsav los ntawm linear lub cev muaj zog tsis muaj traction unit, lub tshuab chav nyob rau sab saum toj ntawm lub tsev yuav raug tshem tawm. Piv txwv tias qhov siab ntawm lub tsev nce mus txog 1000 meters, nws yuav tsum siv lub elevator tsis muaj hlua khi. Lub elevator no yog tsav los ntawm lub cev muaj zog linear nrog high-temperature superconducting technology, lub kauj yog ntsia rau hauv lub hoistway, thiab lub tsheb yog nruab nrog high-performance mus tas li hlau nplaum cov ntaub ntawv. Zoo li lub tsheb ciav hlau maglev, nws yog tswj los ntawm xov tooj cua tsis muaj zog lossis lub teeb tswj tshuab.

—— Thaum lub cev muaj zog ultra-high-speed tig dhau ib qho kev txwv, lub cev muaj zog uas siv cov kabmob dov yuav ua rau sintering thiab puas. Vim li no, xyoo dhau los, lub tshuab hluav taws xob tsis zoo (electromagnetic bearing) tau tsim tawm txawv teb chaws. Cov cuab yeej raug tshem tawm yog siv los ua kom lub zog ntawm lub cev muaj zog levitate hauv huab cua, tshem tawm cov neeg kho tshuab kev sib cuag thiab kev tiv thaiv ntawm lub mover thiab stator, thiab nws qhov kev sib hloov ceev tuaj yeem ncav cuag 25, 000 rpm. ~ 100000r / min los yog ntau tshaj, yog li nws yog dav siv nyob rau hauv high-speed motors thiab high-speed spindle Cheebtsam. Piv txwv li, lub 5-axis controllable electromagnetic high-speed spindle rau ntau txheej txheem tsis siv neeg CNC lathes nyuam qhuav tsim los ntawm Yaskawa Corporation ntawm Nyiv siv ob radial electromagnetic bearings thiab ib tug axial thrust electromagnetic bearing, uas muaj peev xwm dais lub load ntawm lub tshuab. cuab tam nyob rau hauv txhua txoj kev. Nyob rau hauv lub hauv paus ntawm tus ncej, nyob rau hauv tas li ntawd mus rau lub high-ceev lub cev muaj zog, nws kuj yog txawm peem rau nrog ib tug cuab yeej tsis siv neeg kev sib txuas lus ntaus ntawv uas yog siv los ua ntau yam tsis siv neeg CNC lathes.
