Txoj Kev Txhim Kho Rau Peb -Phase Asynchronous Motors
Apr 17, 2026
Rau peb -theem asynchronous motors ua haujlwm tsis tu ncua, kev saib xyuas niaj hnub suav nrog cov hauv qab no: kev tshuaj xyuas pom; xyuas kom meej tias cov kiv cua txias ua haujlwm raug; kuaj xyuas qhov txawv txav; xyuas kom lub coupling kev twb kev txuas yog ruaj ntseg; paub meej tias lub hauv paus mounting bolts yog nruj; kuaj xyuas kev ua haujlwm kom raug (los ntawm kev mloog cov suab txawv txawv); thiab saib xyuas qhov kub thiab txias (siv lub ntsuas kub infrared).
Tsis tas li ntawd, kev sib txuas ntawm cov xov hlau thiab cov neeg sib txuas yuav tsum tau tshuaj xyuas ib ntus, thiab kev ua haujlwm tam sim no yuav tsum raug txheeb xyuas (siv lub ntsuas ntsuas ntsuas). Tsis tas li ntawd, qhov txhab-rotor motors xav tau kev tshuaj xyuas tshwj xeeb ntawm lawv cov txhuam hniav thiab cov hlua khi.
Terminal Identification
⑴ Ua ntej, txheeb xyuas ob qhov pib thiab xaus rau txhua qhov ntawm peb -theem windings. Teem ib lub multimeter rau qhov kev tiv thaiv ntau los ua kev ntsuas; terminals uas yog tib yam -theem winding yuav qhia continuity (zero resistance), hos terminals teej tug mus rau txawv theem yuav qhia tsis muaj txuas ntxiv. Los ntawm kev soj ntsuam cov kev nyeem ntawv multimeter, koj tuaj yeem paub meej qhov txawv ntawm ob lub terminals sib raug rau cov coj ntawm ib zaug -theem winding.
⑵ Tom ntej no, txheeb xyuas qhov "zoo li- npe" terminals (terminals ntawm tib lub polarity) hla cov kab sib txawv. Teem lub analog multimeter rau nws qhov qis tshaj DC tam sim no. Txuas ob lub terminals ntawm ib theem winding mus rau multimeter's probes. Tom qab ntawd, ib ntus kov ob lub davhlau ya nyob twg ntawm * txawv * theem winding mus rau qhov zoo thiab qhov tsis zoo ntawm cov roj teeb qhuav- ntawm tes, raws li. Thaum lub sij hawm meej lub roj teeb txuas mus rau winding, soj ntsuam lub multimeter's koob: yog tias rab koob deflects mus rau sab zoo (ie, viav vias clockwise), ces lub roj teeb lub davhlau ya nyob twg zoo thiab multimeter dub sojntsuam sib haum mus rau qhov zoo li -npe terminals; conversely, yog hais tias lub koob deflects nyob rau hauv opposite kev taw qhia, lub polarity yog thim rov qab.
