Hauv ntiaj teb ntawm kev yuav khoom lag luam, kev hloov pauv ntawm cov tshuab hluav taws xob induction ib txwm muaj mus rauCov Tsav Tsheb Sib Nqus Mus Ib Txhis (PM) Synchronousyuav tsum muaj kev hloov pauv tseem ceeb hauv kev xav txog kev siv tshuab. Txawm hais tias ntau tus engineers tau siv rau kev xaiv cov motors raws li lub zog zaus ntawm lub grid (50Hz / 60Hz), kev xaiv PM motor tig yuav luag tag nrho nyob ib puag ncig ib qho tseem ceeb metric:Qhov Ceev Ntsuas (RPM).
Kev Hloov: Los ntawm Zaus mus rau Qhov Tseeb
Rau cov qauv induction motors, qhov ceev yog ib qho khoom ntawm qhov zaus ntawm lub grid thiab tus naj npawb ntawm cov ncej. Txawm li cas los xij, PM motors yog tsim los ua haujlwm nrog Variable Frequency Drives (VFDs). Hauv lub ecosystem no, lubtsim zaus thiab voltage yog xam rov qab los ntawm lub hom phiaj ceevxav tau los ntawm daim ntawv thov.
Vim Li Cas Kev Ceev Thiaj Li Ua Rau Cov Thev Naus Laus Zis
Qhov tseem ceeb ntawm kev ceev hauv kev xaiv PM lub cev muaj zog yog tsav los ntawm peb yam tseem ceeb ntawm kev siv tshuab:
Lub zog hluav taws xob sab hauv (Back EMF) uas tsim los ntawm lub cev muaj zog PM yog sib npaug ncaj qha rau nws qhov ceev. Yuav kom ntseeg tau tias VFD tuaj yeem tswj tau lub cev muaj zog zoo, cov xov hlau yuav tsum tau tsim tshwj xeeb rau lub hom phiaj RPM.
Tsis zoo li cov cav 50Hz uas "muaj nyob rau ntawm txee", lub cav PM yuav raug tsim los rau qhov zaus ntsuas ntawm 120Hz lossis 37.5Hz kom ntaus tau RPM tshwj xeeb nrog kev ua haujlwm zoo tshaj plaws. Qhov zaus yog ib qho cuab yeej, tsis yog kev txwv.
PM motors feem ntau tshem tawm qhov xav tau gearboxes los ntawm kev khiav ntawm qhov ceev qis heev lossis siab heev. Los ntawm kev txhais qhov ceev ua ntej, cov chaw tsim khoom tuaj yeem ua kom zoo dua qhov sib nqus flux thiab tus lej ncej kom xa cov torque siab tshaj plaws yam tsis muaj kev poob zog tsis tsim nyog.
Cov Lus Qhia Txog Kev Npaj Rau Cov Thawj Coj Kev Yuav Khoom
Thaum xa cov lus nug rau PM motors, kev muab tsuas yog lub zog (kW) tsis txaus. Txhawm rau kom tau txais cov lus hais raug thiab kev tsim qauv zoo tshaj plaws,qhov ceev ua haujlwm ntsuas yuav tsum yog qhov qhia tshwj xeeb tseem ceeb.Los ntawm kev muab qhov tseem ceeb rau qhov ceev, koj tso cai rau tus neeg tsim khoom "rov qab-engineering" cov kev teeb tsa hluav taws xob zoo tshaj plaws, xyuas kom meej tias lub cev muaj zog, kev tsav tsheb, thiab daim ntawv thov ua haujlwm sib haum xeeb zoo meej.
Cov Ntsiab Lus Tseem Ceeb:Ib txwm qhia meej txogQhov Ceev Ntsuas (RPM)ua tus qauv tseem ceeb thaum thov tus nqi PM lub cev muaj zog. Lub zog (kW) ib leeg tsis txaus rau kev tsim lub cev muaj zog kom raug thiab zoo tshaj plaws.
