Qhov zoo ntawm Peb -Phase Asynchronous Motors

Peb -theem asynchronous motors yog ib hom kev siv ntau tshaj plaws ntawm cov motors hauv cov ntawv thov kev lag luam. Lawv lub hauv paus ntsiab lus tseem ceeb yog raws li txoj cai ntawm electromagnetic induction-thaum peb-theem alternating tam sim no yog siv rau stator windings, ib tug rotating magnetic teb yog generated. Lub rotor conductors, txiav cov kab sib nqus ntawm lub zog, tsim kom muaj kev cuam tshuam tam sim no, uas ua rau cov ntaub ntawv torque los tsav lub load. Cov qauv no ua rau nws muaj txiaj ntsig zoo, tab sis nws kuj muaj qee qhov kev txwv. Cov kev tshuaj ntsuam hauv qab no tshuaj xyuas nws cov yam ntxwv ntawm kev ua haujlwm, daim ntawv thov scenarios, thiab tus nqi -kev ua tau zoo.

Technical Advantages: Cov qauv yooj yim thiab txhim khu kev qha
Lub stator thiab rotor ntawm peb -theem asynchronous lub cev muaj zog yog tsim los sib cais. Lub stator muaj ib tug tub ntxhais ntawm stacked silicon steel nplooj ntawv thiab peb -theem windings. Lub rotor muaj nyob rau hauv ob hom: squirrel- tawb thiab qhov txhab-rotor. Squirrel-cage rotors, tsis muaj txhuam thiab cov ntiv tes xoo, muaj cov qauv yooj yim heev, txo qhov tsis ua hauj lwm ntau dua 60% piv rau DC motors, thiab txuas ntxiv kev txij nkawm mus txog 3-5 xyoo. Piv txwv li, nyob rau hauv mining conveyor systems, muaj ntau heev ntawm squirrel{17}}cage motors khiav tsis tu ncua rau 20,000 teev yam tsis muaj kev kho loj. Tsis tas li ntawd, kev sib cuam tshuam ntawm nws cov rotating magnetic teb thiab rotor tam sim no tso cai rau lub cev muaj zog ua tau zoo tshaj 0.85 nyob rau hauv lub teeb loads thiab ze rau 0.95 nyob rau hauv hnyav loads, ho superior rau ib theem motors.

Cov yam ntxwv ntawm kev ua tau zoo: Kev tswj kev nrawm nrawm thiab muaj zog tshaj qhov muaj peev xwm
Thaum ceev tau hloov kho los ntawm kev hloov pauv zaus, peb -theem asynchronous lub cev muaj zog tuaj yeem ua tiav kev tswj tsis tau nrawm los ntawm 0-100Hz, nthuav dav qhov nrawm ntawm peb zaug piv rau cov tsoos electromagnetic ceev- tswj cov motors. Siv cov tshuab textile ua piv txwv, tom qab kev hloov pauv ceev ceev, kev hloov pauv ntawm cov ntaub ntawv poob qis los ntawm ± 5% mus rau ± 1.5%, nce cov khoom tsim nyog tus nqi los ntawm 12%. Nyob rau hauv cov nqe lus ntawm overload muaj peev xwm, nws luv luv - lub sij hawm overload ntau yuav ncav cuag 2-3 zaug lub rated torque, thaum DC motors feem ntau tsuas yog ncav cuag 1.5 zaug. Cov yam ntxwv no tshwj xeeb tshaj yog muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej uas yuav tsum tau muaj lub zog siab nrawm, xws li cranes thiab stamping presses-kev sim tiag tiag ntawm cov khoom siv tsheb tau pom tias stamping presses siv peb-theem asynchronous motors tau ntsib 23% txo lub zog noj thaum pib thiab 40% txuas ntxiv hauv cov khoom siv.
