Kev Ntsuam Xyuas Tag Nrho Cov Lus Cim: Ib qho kev qhia tob los ntawm cov hauv paus rau kev siv

Hauv kev lag luam niaj hnub thiab lub neej niaj hnub, lub cev muaj zog yog ubiquitous, powering cov khoom siv hauv tsev thiab muab cov haujlwm ua haujlwm tau zoo ntawm cov kab ntau lawm. Qhov tseem ceeb ntawm cov motors yog pom tus kheej. As the "identity card" and "operation manual" of motors, motor symbols encapsulate rich and crucial information, playing a decisive role in the correct selection, safe operation, efficient maintenance, and troubleshooting of motors. Ib qho kev nkag siab zoo ntawm lub cev muaj zog yog qhov kev txawj ntse rau txhua tus kws kho lub cev muaj zog, cov tshuab hluav taws xob, thiab tus neeg zoo siab.

1.Qhov qhov tseem ceeb thiab tus nqi ntawm lub cev muaj zog

Lub cev muaj zog tsis yog tsuas yog polaphical lossis cov lej sib txuas; Lawv muaj cov sawv cev zoo ntawm cov qauv muaj zog, kev ua tau zoo, kev ua kom muaj kev nyab xeeb, thiab cov cai thov. Piv txwv li, thaum lub caij muaj zog, lub zog (txhais tau tias yog cov khoom siv hluav taws xob kom ruaj khov kho Ua tsis tiav vim tsis muaj zog lossis voltage tsis sib xws. Qhov ceev (RPM) lub cim qhia meej qhia txog lub cev muaj zog xws li kev ua haujlwm nruj me ntsis, feem ntau cuam tshuam ntau yam ua tau zoo thiab cov khoom zoo. Cov chav kawm rwb thaiv tsev (piv txwv li, "B", "F") Ua tsis tiav, kom muaj kev nyab xeeb rau lub cev muaj zog thiab kev ua haujlwm ruaj khov, ntev lub neej pabcuam, thiab txo cov cuab yeej tu khoom thiab kev phom sij kev nyab xeeb.

2.Multipine Cov Kev Kawm Ntawv Tshwj Xeeb thiab cov ncauj lus kom ntxaws ntawm lub cev muaj zog

1. a.single-theem induction induction lub cev muaj zog siv tau dav siv nyob rau hauv cov khoom siv hluav taws xob hauv yim neeg thiab cov dej me me. Lawv cov cim nruab nrab ib puag ncig cov kev ua haujlwm. Dhau li ntawm cov ntsuas pom zoo li lub hwj chim, hluav taws xob, thiab ntau capacitor-pib qhia cov ntaub ntawv ntsuas ntawm qhov pib thiab taws capacitors.
