Tsav tsheb vim lub tshuab pa
Qhov txias ntxuam ntawm lub tshuab yog txawv txav, ua rau lub cev kom sov tuaj.
Lub cav tsis muaj qhov nruab nrog ntsuas kub
Kev kub ntxhov yog kub heev
Tsav tsim tsis tsim nyog
Yuav ua li cas tiv thaiv tau demagnetization ntawm cov hlau nplaum tas li? ? ?
Txhim kho ntawm cov hlau nplaum hluav taws xob tas li
Demagnetization muaj feem xyuam rau lub zog xaiv ntawm cov hlau nplaum tas mus li.
Ua tib zoo xaiv lub hwj chim ntawm lub tshuab hlau nplaum tas li tuaj yeem tiv thaiv los yog ncua cov pa phem.
Lub ntsiab tseem ceeb rau lub demagnetization ntawm cov hlau nplaum synchronous mus tas li yog tias qhov kub yog siab dhau lawm thiab qhov tshaj yog lub ntsiab ua rau kub tshaj.
Yog li, thaum xaiv lub zog ntawm cov hlau nplaum tas li, yuav tsum muaj ib qho paj tau paj. Raws li qhov tseeb qhov teeb meem ntawm lub load, feem ntau hais txog 20% yog haum.
Tsis txhob pib hnyav nce pib thiab nquag pib
Lub cage hom asynchronous pib synchronous mus tas li hlau nplaum lub cev ua kom nws tsis txhob pib pib los yog nquag pib ntawm hnyav load.
Thaum lub sij hawm pib txheej txheem asynchronous, pib lub pib torque yog oscillating. Nyob hauv qhov pib nqeeb hav dej, tus pas ntsuas ntawm magnetic magnetic yog demagnetizing rau lub rotor ncej.
Yog li, nws yog qhov zoo tshaj kom tsis txhob muaj overloading thiab nquag pib ntawm asynchronous mus tas li hlau nplaum synchronous motors.
