Motors yog ib qho ntawm cov khoom siv hluav taws xob hauv lub neej niaj hnub. Dab tsi yog qhov txawv ntawmhloov pauv zaus motorsthiab zoo tib yam industrial zaus motors?
Motors yog cov khoom siv hluav taws xob uas tso siab rau lub hauv paus ntsiab lus ntawm electromagnetic induction kom paub lub zog ntawm lub zog thiab kev sib kis. Nws lub luag haujlwm tseem ceeb yog los tsim kom muaj lub zog tsav tsheb raws li qhov chaw ntawm hluav taws xob lossis lub zog siv tshuab.
Ordinary motorsthiab qhov sib txawv zaus motors yog ob qho tib si asynchronous motors. Nws txoj haujlwm ua haujlwm: Lub stator winding ntawm lub cev muaj zog yog peb-theem winding uas yog symmetrical hauv qhov chaw. Thaum peb-theem symmetrical AC tam sim no ntxiv rau lub stator winding, lub rotating magnetic teb yuav raug tsim nyob rau hauv lub cev muaj zog. Qhov no rotating magnetic teb txiav lub rotor winding, yog li tsim ib tug induced tam sim no nyob rau hauv lub rotor winding. Lub rotor nqa tam sim no yuav tsim hluav taws xob quab yuam nyob rau hauv qhov kev txiav txim ntawm stator rotating magnetic teb, yog li tsav lub cev muaj zog tig.
Lub cev muaj zog tsis sib xws thiab cov tshuab hluav taws xob zoo tib yam muaj ntau zaus Cov motors Ordinary motors muaj ntau dua, tab sis dab tsi yog qhov zoo ntawm cov motors sib txawv piv rau cov motors zoo tib yam?
- Lub cev muaj zog sib txawv tuaj yeem ua haujlwm ntawm qhov tsawg zaus thiab voltages. Thiab lawv tuaj yeem pib yam tsis muaj kev cuam tshuam tam sim no. Ntau txoj kev braking yog muab los ntawm inverter tuaj yeem siv rau kev nrawm nrawm kom ua tiav qhov pib thiab nres. Vim tias lub cev muaj zog sib txawv tuaj yeem ua tiav cov haujlwm xav tau ntau dua thiab ua haujlwm hnyav dua li cov motors zoo tib yam. Yog li ntawd, lub cev muaj zog tsis sib haum xeeb muaj qib rwb thaiv tsev ntau dua li cov motors zoo tib yam hauv kev tsim khoom, yuam cov tshuab cua txias (ua-nyob rau hauv cov kiv cua txias), muaj zog txhua yam muaj zog hauv cov qauv, zoo rotor bearings thiab kev pab lub neej ntev dua li qub motors.
- Raws li peb txhua tus paub, cov motors zoo tib yam tuaj yeem ua haujlwm raws li qhov xwm txheej ntawm50 Hz fais fab zaus. Yog tias qhov sib txawv ntawm qhov sib txawv loj dhau lawm, lub cev muaj zog yuav kub hnyiab los yog hlawv lub cev muaj zog. Txawm li cas los xij, lub cev muaj zog tuaj yeem hloov kho qhov ceev ntawm lub cev muaj zog ntawm txhua qhov ceev hauv qhov nrawm yam tsis muaj kev puas tsuaj. Raws li ib txwm muaj, lub cev muaj zog sib txawv tuaj yeem ua haujlwm tsis tu ncua nyob rau hauv qhov ntsuas nrawm ntawm qhov ntsuas tag nrho, thiab qhov kub ntawm lub cev muaj zog yuav tsis pub dhau lub cev muaj zog calibration nqi.
- Txawm hais tias qhov sib txawv zaus motors yog me ntsis kim dua li cov motors zoo tib yam hauv nqe, lawv qhov zoo yog qhov pom tseeb heev. AC ceev tswj txoj kev ntawm zaus converter ntxiv rau qhov sib txawv zaus lub cev muaj zog tuaj yeem txhim kho qib ntawm cov tshuab automation thiab ntau lawm efficiency. Tsis tas li ntawd, qhov muag pib ua haujlwm ntawm lub zaus hloov pauv kuj tseem txo qhov cuam tshuam ntawm cov tam sim no loj ntawm daim phiaj hluav taws xob thaum pib lub cev muaj zog, thiab txuag ntau lub zog ntau dua li cov motors zoo tib yam.
Raws li tus nqi ntawm cov zaus hloov pauv thiab hloov pauv zaus lub cev muaj zog txuas ntxiv poob qis, daim ntawv thov kev hloov pauv zaus yuav dhau los ua ntau dua.
