Nrog rau kev txhim kho kev lag luam tas mus li thiab kev txhim kho txuas ntxiv ntawm tib neeg txoj kev ua neej nyob, qhov kev thov rau lub zog tau nce siab thiab siab dua.Nyob rau tib lub sijhawm, teeb meem xws li kev ua qias tuaj ib puag ncig thiab kev hloov pauv huab cua kuj tseem muaj zog ntxiv.Tawm tsam keeb kwm yav dhau los no, kev txhim kho kev siv hluav taws xob zoo thiab txo qis kev siv hluav taws xob tau dhau los ua kev nyuaj rau txhua lub teb chaws.Cov hlau nplaum ruaj khov lub cev muaj zog raws li hom tshiab, kev ua haujlwm siab, lub zog txuag lub cev muaj zog, nws lub zog txuag cov nyhuv tau nyiam ntau yam.Niaj hnub no peb saib lub hauv paus ntsiab lus thiab qhov zoo ntawm cov hlau nplaum ruaj khov motors, thiab tseem qhia rau koj ob qhov teeb meem ntawm kev txuag hluav taws xob Minten low-voltage mus tas li hlau nplaum motors hauv kev lag luam metallurgy thiab kev tiv thaiv ib puag ncig.
Lub hauv paus ntsiab lus ntawm mus tas li hlau nplaum lub cev muaj zog
Lub cev muaj zog hlau nplaum tas mus li yog ib hom lub cev muaj zog uas siv cov kev sib cuam tshuam ntawm cov hlau nplaum tsim los ntawm cov hlau nplaum ruaj khov thiab cov hluav taws xob tam sim no los hloov hluav taws xob rau hauv lub zog siv tshuab.Nws cov qauv yooj yim suav nrog cov hlau nplaum ruaj khov, stator thiab rotor.Cov hlau nplaum ruaj khov ua haujlwm ua tus ncej hlau nplaum ntawm lub cev muaj zog thiab cuam tshuam nrog cov tam sim no hauv stator coil los ntawm nws tus kheej magnetic teb los tsim torque thiab hloov txhua lub zog rau lub rotor, paub txog kev hloov pauv ntawm hluav taws xob mus rau txhua yam zog.
Piv nrog rau cov tsoos induction lub cev muaj zog, cov hlau nplaum ruaj khov muaj cov hauv qab no zoo:
1. Kev ua haujlwm siab: Cov tsoos induction motors muaj lub zog qis vim qhov tseeb tias lawv cov hlau nplaum yog tsim los ntawm cov tam sim no nyob rau hauv lub kauj thiab muaj induction poob.Thaum lub magnetic teb ntawm cov hlau nplaum ruaj khov lub cev muaj zog yog muab los ntawm cov hlau nplaum ruaj khov, uas tuaj yeem hloov hluav taws xob hluav taws xob mus rau hauv lub zog siv hluav taws xob ntau dua.Raws li cov kev tshawb fawb cuam tshuam, qhov ua tau zoo ntawm cov hlau nplaum ruaj khov motors tau nce li ntawm 5% mus rau 30% piv nrog cov tsoos induction motors.
2. Lub zog muaj zog siab: Lub zog sib nqus ntawm cov hlau nplaum ruaj khov lub cev muaj zog yog siab dua li ntawm induction lub cev muaj zog, yog li nws muaj zog ntau dua.
3. Kev txuag hluav taws xob: Raws li cov hlau nplaum ruaj khov motors muaj kev ua haujlwm siab thiab lub zog siab ceev, qhov no txhais tau tias lawv tuaj yeem tso tawm ntau lub zog siv hluav taws xob nrog tib lub zog nkag hauv tib lub ntim thiab qhov hnyav, yog li paub txog kev txuag hluav taws xob.
Kev hloov pauv ntawm qhov tsis muaj peev xwm asynchronous induction motors los ntawm cov hlau nplaum ruaj khov, ua ke nrog kev kho cov kev ua haujlwm thiab kev tswj xyuas zaus ntawm cov khoom siv hluav taws xob tsis zoo, tuaj yeem txhim kho lub zog ntawm cov khoom siv hluav taws xob zoo, thiab cov nram qab no 2 cov ntaub ntawv raug siv. yog rau siv.
