1. Vim muaj tshwm sim ntawm kev plam tom qab lub cav demagnetization, ib qho kev sib txawv tam sim no tshwm sim hauv lub tshuab hluav taws xob rotor, ua rau poob hauv lub rotor Circuit Court. Yog tias qhov sib txawv zaus tam sim no tshaj li cov muaj nuj nqis uas muaj cai, nws yuav ua rau lub rotor kom muaj ntau dua. Tshwj xeeb tshaj yog rau cov nqi hluav taws xob siab ntau nrog kev txias txias, lawv cov thermal muaj peev xwm txo qis, thiab lub rotor yog ntau dua rau overheating ntau dua. Lub zog sib txawv tam sim no ntawm lub rotor kuj tseem yuav ua rau lub zos sib tiv tauj los yog txawm hlawv ntawm lub rotor lub rotor lub rotor lub rotor lub rotor thiab rings.
2. Tom qab cov tshuab hluav taws xob demagnetize nkag mus rau Asynchronous kev ua haujlwm, cov kev sib npaug ntawm lub tshuab hluav taws xob txo qis ntawm lub zog hluav taws xob. Qhov loj dua lub zog loj nqa ua ntej demagnetization, ntau dua cov khauj khaum, thiab qhov sib npaug ntawm cov khoom siv hluav taws xob sib npaug. Tom qab Demagnetization hauv lub nra hnyav, lub tshuab hluav taws xob yuav hloov dua siab dhau los ntawm overcurrent.
3. Rau cov chav dej loj uas tsim hluav taws xob nrog cov nqi cua txias thiab cov nqi siab tshaj plaws ntawm qhov nruab nrab asynchronous torque yog tus me, thiab inertia tas li kuj tseem raug txo. Lub rotor kuj tseem qhia txog cov asymmetry tseem ceeb hauv kev ncua ntev thiab hloov pauv. Vim yog cov laj thawj no, tom qab Demagnetization hauv cov nra hnyav, lub zog thiab lub zog ntawm lub tshuab hluav taws xob no yuav muaj kev ua haujlwm tsis zoo rau oscillations. Rau hydro cov tshuab hluav taws xob, vim tias muaj qhov nruab nrab me me asynchronous thiab cov aymmermetry thiab cov aav meem zoo sib xws tseem tshwm sim thaum lub sijhawm Demagnetization ua haujlwm hnyav. Hauv qhov no, ib qho loj lossis txawm ntev tshaj lub cev muaj zog yuav ua rau lub tshuab hluav taws xob thiab tau kis rau lub tshuab hluav taws xob los ntawm stator. Nyob rau lub sijhawm no, cov khaub ncaws hnav kuj tsis muaj kev hloov pauv, thiab nws tus nqi siab tshaj plaws yuav ncav cuag 4% rau 5%, ua rau lub tshuab hluav taws xob ua ntu zus. Cov xwm txheej no ncaj qha hem thawj qhov kev nyab xeeb ntawm cov neeg coob.
4. Lub sijhawm Demagnetization ua haujlwm, cov xau ntawm kev sib nqus flux ntawm qhov kawg ntawm stator yog txhim kho, uas yuav ua rau overheating ntawm qhov kawg Cheebtsam thiab OLD hlau Cores.
