Nqa cov cuab yeej xuab zeb kev hloov kho
Tom qab xaiv cov qauv ntawm lub cav ntoo thiab tus neeg tsav tsheb raws li lub thauj, lub zog, thiab lwm yam., Kuj yog hais txog qhov chaw ntawm qhov parameter ntawm kev khiav ceev kev ua haujlwm hauv ib daim ntawv thov. Pom zoo rau kev saws me nyuam lub plhaw zaus ntawm tus neeg tsav tsheb stepper thiab qhov kev hloov ntawm qhov kev tswj ntawm qhov kev ua haujlwm tsis yog siv los txhawm rau kho qhov ceev ntawm kev ua lub kauj ruam. Qhov tseeb tiag, nws yuav tsum tswj cov kauj ruam ntawm tus kauj ruam hauv theem hauv tsev. Kev pauv hloov li niaj zaus ntawm txoj kev tsav ceev yog muab faib rau cov hom nram qab no:
Ua ntej, tus neeg tsav tsheb khiav ceev
Zoo:
1 muaj cov qauv yooj yim ntawm AC synchronous lub cev muaj zog thiab kev ceev cov kev tswj zoo ntawm DC lub cev;
2 Thaum siv qis qis, lub hwjchim muaj zog thiab qhov kev ua haujlwm qiv rov qab EMF ntawm kev kub ceev yog muaj kev cog lus, thiab kev lag luam yog kev ntseeg;
3 Tsis muaj qhov poob qis ntxiv, kev ua haujlwm siab, tsim kom muaj kev pib thiab ceev kev cai ntawm high-speed muaj peev xwm loj dua lub tshuab synchronous.
Disadvantages: Qhov muaj peev xwm tsawg dua, thiab lub peev xwm ntawm thawj lub cav tsis tuaj yeem siv tau.
Qhov ob, tus cai tswj hwm ntawm tus qauv stator
Zoo: 1 yooj yim Circuit Court, me me thiab loj tus nqi; 2 yooj yim rau kev siv thiab tu.
Cov tsis zoo: 1 nce qhov poob qis thaum tus txheej txheem ceev kev cai, qhov poob no ua rau lub cua kub rotor, qhov ua tau zoo qis;
2 qhov ceev ntau yog tsawg;
3 yuav tsum muaj kev siv lub cav qis tshaj, xws li tsim tshwjxeeb rau lub cav,
Yog li, cov yam ntxwv yog mos, feem ntau haum rau asynchronous motors nram qab 55kW.
Peb, txoj hlua rotor kuj ceev ceev
Zoo: 1 tsis tshua muaj kev txwv, yooj yim rau tus tswv;
2 cov nqi qis; 3 tsis muaj teeb meem electromagnetic harmonic.
Tsis zoo:
1 hlua castor hlau resistor tau tsuas yog siv rau kev cai tswj hwm stepwise. Yog tias cov kua ua haujlwm tsis zoo siv rau cov kev tswj kev ua tsis muaj zog, kev saib xyuas thiab txij nkawm yuav tsum yog siab;
2 lub hwj huam tshaj ntxiv thaum lub sij hawm kev tswj ceev ceev hloov mus rau hauv kev poob hauv daim ntawv ntawm txoj hlua kuj cua sov yog tsawg. 3 Cov kev ceev ceev tsis loj.
Plaub, cov kev cai tswjhwm ntawm tus cwj pwm hloov tshuab electromagnetic
Zoo:
1 yooj yim qauv, me me tswj cov cuab yeej, tsawg tus nqi;
2 txhim khu kev lag luam, txhim kho yooj yim;
3 tsis muaj kev cuam tshuam dab tsi.
Tsis zoo:
1 ceev tsis loj, vim hais tias tus electromagnetic slip clutch nws tus kheej muaj qhov sib txawv loj, yog li qhov siab tshaj ntawm tus tawm ntawm lub qhov hluav taws xob tsuas yog 80% mus txog 90% ntawm kev sib tsoo ntawm lub cav;
2 Ib feem yog hloov dua siab tshiab rau hauv cua sov hauv daim ntawv ntawm lub tshav kub, uas yog qhov muaj tseeb.
