Vim li cas ho tsis siv cov motors zoo tib yam li cov motors sib txawv?

Cov pahluav taws xob lub cev muaj zogs feem ntau yog tsim los rau cov ntawv thov tsis tu ncua thiab qhov hluav taws xob tsis tu ncua, tab sis ntsib cov kev txwv tseem ceeb thaum nws los txog rau kev ua haujlwm sib txawv. Qhov tsis muaj peev xwm hloov pauv hloov zaus thiab qhov hluav taws xob yog qhov laj thawj tseem ceeb vim li cas lawv tsis tuaj yeem siv tau zoo livariable zaus lub cev muaj zogs.

Ib qho ntawm cov teeb meem tseem ceeb nrog cov pa motors yog lawv cov qauv tsim, uas yog optimized rau ib qho kev khiav hauj lwm zaus, feem ntau yog tus qauv fais fab zaus ntawm 50 lossis 60 Hz. Thaum siv cov tsav tsheb sib txawv los tswj cov kev ceev ntawm cov motors, cov yam ntxwv ntawm lub cev muaj zog ua tsis raws li qhov yuav tsum tau ua ntawm kev ua haujlwm nrawm. Qhov sib txawv zaus tsav hloov cov input zaus thiab voltage, uas tuaj yeem ua rau muaj teeb meem kev ua haujlwm nrog cov pa motors.

Tsis tas li ntawd, cov teebmeem ntawm covVFD lub cev muaj zogntawm lub cev muaj zog kuj tuaj yeem ua rau muaj kev puas tsuaj. Piv txwv li, lub zog rwb thaiv tsev ntawm lub cev muaj zog windings tej zaum yuav tsis txaus los tswj qhov voltage spikes thiab variations qhia los ntawm VFD. Qhov no tuaj yeem ua rau lub rwb thaiv tsev tsis ua haujlwm ntxov, ua rau kev kho kim lossis hloov pauv.

Thaum qis ceev, txias yog lwm qhov teeb meem tseem ceeb. Ordinary motors cia siab rau ib qho tshwj xeeb airflow tsim los ntawm lawv cov qauv tsim kom zoo dissipate cua sov. Thaum khiav ntawm qis qis, cov nyhuv txias yog txo, ua rau overheating thiab muaj peev xwm puas tsuaj. Qhov no yog qhov teeb meem tshwj xeeb hauv cov ntawv thov uas yuav tsum tau khiav qis qis rau lub sijhawm ntev, vim tias lub cev muaj zog yuav tsis tuaj yeem tswj xyuas qhov kub thiab txias.

Cov kev txwv tsim los ntawm cov motors zoo tib yam, ua ke nrog cov kev cuam tshuam tsis zoo ntawm inverters ntawm rwb thaiv tsev thiab cua txias, ua rau lawv tsis tsim nyog rau kev siv ntau zaus. Rau kev tswj ceev ceev thiab txhim khu kev qha, kev ua haujlwm sib txawv ntawm lub cev muaj zog yog qhov tseem ceeb vim tias lawv tau tsim tshwj xeeb los ua kom tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv.
