Yuav ua li cas servo tswj system ntawm high -ceev T- lub hnab tsho- ua tshuab ua kom zoo kom ua tiav lub zog qis?

Raws li cov cuab yeej tseem ceeb ntawm kev lag luam ntim khoom niaj hnub no, lub zog noj qib ntawm kev kub ceev T- lub tsho hnab ntim tshuab ncaj qha cuam tshuam cov nqi tsim khoom thiab cov txiaj ntsig ib puag ncig. Lub servo tswj system, raws li "lub plawv" ntawm lub hnab- ua tshuab, plays lub luag hauj lwm txiav txim siab nyob rau hauv lub zog noj optimization los ntawm precisely tswj kev sib koom tes ntawm traction, kub sealing thiab txiav. Raws li qhov kev txhim kho tshiab tshaj plaws ntawm kev lag luam thev naus laus zis, daim ntawv no tau piav qhia txog kev siv hluav taws xob tsawg tsawg ntawm kev tswj hwm servo los ntawm plaub qhov loj: kev xaiv kho vajtse, tswj lub tswv yim, lub zog rov qab thiab kev ua kom zoo dua qub.
1.Hardware Xaiv: Match Load Requirements kom tsis txhob muaj fais fab rov qab
1.1 Precise Matching ntawm Tsav thiab Tsav Tsheb
Cov hnab ntim khoom ib txwm siv feem ntau ua rau lub zog pov tseg vim lub zog ntau dhau ntawm lub cev muaj zog. Piv txwv li, ib yam ntawm lub hnab ntim tshuab yuav tsum tsuas yog 3 kilowatts ntawm lub hwj chim nyob rau hauv rated load tej yam kev mob tab sis yog tiag tiag nruab nrog ib tug 5 kilowatts lub cev muaj zog, uas ua rau txo efficiency ntawm tsawg load lub sij hawm. Qhov kev daws teeb meem zoo tshaj plaws yog xaiv lub cev muaj zog raws li kev ua haujlwm tiag tiag. Piv txwv li, cov hlau nplaum ruaj khov synchronous lub cev muaj zog tuaj yeem ntsuas ntau dua 95% ua haujlwm tau zoo, 10 txog 15 feem pua ​​​​ntau dua li asynchronous motors. Tsis tas li ntawd, tus neeg tsav tsheb yuav tsum txhawb nqa dynamic voltage regulation functions los kho cov zis voltage nyob rau hauv lub sij hawm raws li load thiab txo passive zog poob.
