Peb -Phase Asynchronous Motors: Cov Lus Qhia Tiv Thaiv Kom Pib Ua Tsis Taus
Jan 20, 2026
Tso lus
A peb -theem asynchronous motors' rotor ceev lags qab nws rotating magnetic teb, generating induced tam sim no thiab electromagnetic torque rau lub zog conversion. Muab faib los ntawm cov qauv rotor rau hauv squirrel- tawb thiab qhov txhab- hom rotor, nws ua tau zoo dua ib zaug -theem motors hauv kev ua haujlwm thiab cov khoom txuag.Squirrel-cage motorsyog tus nqi- zoo thiab txhim khu kev qha tab sis nyuaj rau kev tswj hwm, thaum lub qhov txhab-rotor variants siv lub nplhaib plam thiab sab nraud rheostats los txhim kho kev pib thiab ceev tswj.
Nws lub hauv paus ntsiab lus yog nyob ntawm qhov sib npaug peb -theem AC muab rau stator windings, tsim kom muaj qhov sib nqus sib nqus. Daim teb no txiav cov rotor nyob ruaj ruaj, inducing tam sim no ntawm electromagnetic induction. Tam sim no - nqa rotor conductors ces ntsib electromagnetic quab yuam, tsav kev sib hloov nyob rau hauv lub magnetic teb txoj kev.
Local Winding Burnout
Ua rau muaj xws li tsis zoo sealing ua rau corrosive ingress, bearing puas-induced stator-rotor kev sib txhuam (sweep), winding kev sib txhuam nrog kawg npog, ntev - lub sij hawm overload, thiab mechanical vibration-tsav rwb thaiv tsev laus.
Kev tiv thaiv: tshem tawm cov xau; xyuas kom muaj cua sov kom zoo (80-100 degree) thiab ntxuav thaum sib dhos; zam cov ncej machining thiab tswj stator-rotor alignment; txwv tsis pub roj sib tov; tshuaj xyuas lub cev tsis muaj zog kom huv si ua ntej siv; tiv thaiv overload thiab nquag pib.
Ib/ob -Phase Winding Burnout
Feem ntau tshwm sim los ntawm theem- poob haujlwm. Lub cev muaj zog khiav tuaj yeem ua haujlwm txuas ntxiv tab sis nrog kev txo qis thiab tsis sib npaug tam sim no, overheating windings. Lub cev muaj zog nyob ruaj ruaj nrog theem poob yuav tsuas yog hum thiab tsis pib, vim tias lub tshuab hluav taws xob sib nqus tsis tuaj yeem tsim qhov pib torque.
