Qhov thib ob, kev nkag siab thiab qhov tseeb ntawm "tsis muaj kev poob"

 

Qhov zoo tshaj tsis poob
Nyob rau hauv cov xwm txheej zoo, yog tias cov hlau poob (hysteresis poob thiab eddy tam sim no poob hauv cov tub ntxhais hlau) thiab cov neeg kho tshuab poob (cov kabmob kev sib txhuam poob, cua tsis kam, thiab lwm yam) hauv lub cev muaj zog tsis quav ntsej, lub zog hloov pauv ntawm cov hlau nplaum ruaj khov synchronous. lub cev muaj zog tuaj yeem nyob ze rau 100% vim tias tsis muaj qhov tsis txaus siab, uas yog, hu ua "tsis muaj kev poob". Qhov no yog raws li qhov theoretical assumption tias raws li qhov kev xav no, lub zog hluav taws xob nkag mus rau stator winding yuav luag tag nrho hloov mus rau hauv cov khoom siv hluav taws xob.
Kev poob qhov tseeb
Hlau poob: Hauv kev ua haujlwm tiag tiag, silicon steel ntawv hauv stator core yuav tsim hysteresis poob thiab eddy tam sim no poob nyob rau hauv qhov kev txiav txim ntawm alternating magnetic teb. Hysteresis poob yog vim hysteresis cov yam ntxwv ntawm cov khoom tseem ceeb, uas ua rau cov hlau nplaum nyob rau hauv cov tub ntxhais ntxeev dua thiab siv zog thaum lub magnetic teb hloov. Eddy tam sim no poob yog tshwm sim los ntawm eddy tam sim no induced los ntawm alternating magnetic teb nyob rau hauv cov tub ntxhais, uas generates tshav kub ntawm cov kuj ntawm cov tub ntxhais thiab siv zog.
Mechanical poob: lub rotor ntawm lub cev muaj zog nyob rau hauv cov txheej txheem kev sib hloov, cov kabmob yuav tsim kev sib txhuam tsis zoo, thaum lub cev muaj zog tig thiab cov huab cua nyob ib puag ncig muaj kev sib txheeb, yuav ua rau cua tsis kam. Cov neeg kho tshuab poob no txo ​​cov efficiency ntawm lub cev muaj zog.
Kev poob qis: suav nrog kev poob los ntawm kev sib cuam tshuam ntawm kev txiav txim siab sib nqus sib nqus hauv stator thiab rotor, thiab qhov poob ntxiv los ntawm kev tsim khoom thiab lwm yam. Txawm hais tias qhov ua tau zoo ntawm cov hlau nplaum ruaj khov synchronous motors yog qhov siab, cov kev poob tiag no tsis tuaj yeem tsis quav ntsej.
Thib peb, cov yam ntxwv ntawm AC lub cev muaj feem cuam tshuam
Adaptability ntawm AC fais fab mov
