Waa maxay iska caabinta dabaylaha stator ee motor asynchronous saddex-waji ah in loo tixgeliyo mid caadi ah ku xiran tahay awoodda?(Marka loo eego isticmaalka buundada iyo xisaabinta iska caabbinta ku salaysan dhexroorka siliga, waa wax aan macquul ahayn.) Matoorada ka hooseeya 10KW, multimeter-ku kaliya wuxuu cabbiraa dhowr ohms.55KW, multimeter-ku wuxuu muujinayaa dhowr meelood oo meel.Iska daa falcelinta kicinta hadda.Matoorka xidigta 3kw, multimeter-ku wuxuu cabbiraa caabbinta dabaysha ee weji kasta si uu u ahaado agagaarka 5 ohms (sida ku cad magaca mashiinka, hadda: 5.5A. Awoodda awoodda = 0.8. Waxaa la xisaabin karaa in Z=40 ohms, R = 32 ohms).Farqiga u dhexeeya labada ayaa sidoo kale aad u weyn.

Laga soo bilaabo bilawga mootada ilaa heerka hore ee hawlgalka culayska buuxa, matoorku wuxuu shaqeeyaa wakhti gaaban heerkulkuna ma sarreeyo.Ka dib marka uu socdo 1 saac, heerkulku si dabiici ah ayuu u kacayaa ilaa xad, matoorku wax badan ma hoos u dhici doonaa hal saac ka dib?Sida muuqata maya!Halkan, waxaan rajeynayaa in saaxiibada khibrada leh ee koronto yaqaanku ay kuu soo bandhigi karaan sida aad u cabbirto.Saaxiibada sidoo kale ku wareersan hagaajinta matoorada ayaa wadaagi kara sida aad u fahantay?

Ku dar sawir si aad u aragto:

Iska caabbinta dabaysha saddexda weji ee matoorka waxaa lagu qiyaasaa sida soo socota:

1. Fur qaybta isku xidhka ee u dhaxaysa matoorada.

2. Isticmaal cabbirka caabbinta hoose ee multimeter-ka dhijitaalka ah si aad u cabbirto caabbinta bilawga iyo dhammaadka saddexda dabaylo ee matoorka.Xaaladaha caadiga ah, iska caabbinta saddexda dabaysha waa inay siman yihiin.Haddii uu khalad jiro, khaladku kama badnaan karo 5%.

3. Haddii caabbinta matoorku ka weyn tahay 1 ohm, waxaa lagu qiyaasi karaa buundada hal gacan.Haddii iska caabbinta matoorku ka yar tahay 1 ohm, waxaa lagu cabbiri karaa buundada laba-gacmood.

Haddii uu jiro farqi weyn oo u dhexeeya iska caabbinta gawaarida, waxay la macno tahay in dabaylaha matoorku leeyahay wareegyo gaaban, wareegyo furan, alxanka liidata iyo khaladaadka tirada wareegyada.

4. Caabbinta dahaarka ee u dhexeeya dabaylaha iyo iska caabbinta dahaadhka ee u dhexeeya dabaylaha iyo qolofka waxa lagu qiyaasi karaa:

1) Matoorka 380V waxaa lagu cabiraa megohmmeter oo cabirkiisu yahay 0-500 megohms ama 0-1000 megohms.Iska caabbinta dahaarka ma noqon karto wax ka yar 0.5 megohms.

2) Isticmaal megohmmeter-ka cabiradiisu tahay 0-2000 megohms si aad u cabbirto matoorka-voltage-ka sare.Iska caabbinta dahaarka kama yaraan karto 10-20 megohms.
