Ib lub tshuab uas hloov lub zog hluav taws xob mus ua lub zog tshuab hu ua lub cev muaj zog hluav taws xob. Cov no yooj yim hauv kev tsim, yooj yim siv, pheej yig, ua haujlwm tau zoo, tsis tas yuav saib xyuas, thiab txhim khu kev qha. Peb-theem induction motors yog ib hom thiab txawv ntawm lwm hom hluav taws xob motors. Qhov txawv tseem ceeb yog tias tsis muaj kev sib txuas hluav taws xob los ntawm lub rotor winding mus rau txhua qhov chaw muab khoom. Tam sim no thiab voltage xav tau hauv lub rotor circuit yog muab los ntawm induction los ntawm stator winding. Qhov no yog qhov laj thawj hu ua lub cev muaj zog induction. Tsab xov xwm no piav qhia txog Squirrel cage induction motor, uas yog ib hom peb-theem induction motor.
Lub cev muaj zog Induction Squirrel Cage yog dab tsi?
Kev Txhais Lus: Lub cev muaj zog squirrel cage yog ib hom ntawm cov motors induction. Txhawm rau tsim kev txav mus los, nws ua kom lub zog hluav taws xob tawv. Raws li lub qhov tso zis txuas nrog lub rotor sab hauv uas zoo li lub tawb. Yog li ntawd nws hu ua lub tawb squirrel. Ob lub hau kawg i.e., lub voj voog hauv cov duab yog koom nrog los ntawm rotor bars. Cov no ua raws li EMF i.e., tsim los ntawm stator. EMF no kuj tsim lub tsev sab nraud uas ua los ntawm cov ntawv hlau laminated thiab cov hlau coiling. Ob qhov tseem ceeb ntawm txhua hom induction motor yog stator thiab rotor. Lub tawb squirrel yog ib txoj hauv kev yooj yim ntawm kev rub cov nyhuv electromagnetic induction. Lub cev muaj zog 4-pole squirrel cage induction tau qhia hauv qab no.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub cev muaj zog induction squirrel cage
Lub cev muaj zog induction squirrel ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetism. Thaum lub stator winding tau muab nrog thee-phase AC, nws tsim lub zog sib nqus tig (RMF) uas muaj qhov ceev hu ua synchronous speed. RMF no ua rau muaj hluav taws xob induced hauv rotor bars. Yog li, qhov tam sim no ntws los ntawm qhov ntawd. Vim yog cov rotor currents no, lub zog sib nqus tus kheej tau tsim uas cuam tshuam nrog lub zog stator. Tam sim no, raws li lub hauv paus ntsiab lus, lub zog rotor pib tawm tsam nws qhov ua rau. thaum RMF ntes lub zog rotor, lub zog rotor poob rau xoom. Tom qab ntawd yuav tsis muaj lub zog sib piv ntawm rotor thiab RMF.
Yog li ntawd, lub zog xoom tangential raug ntsib los ntawm lub rotor thiab txo qis rau ib pliag. Tom qab qhov kev txo qis no hauv lub sijhawm ntawm lub rotor, lub zog rotor tam sim no raug tsim dua los ntawm kev tsim kho dua tshiab ntawm kev txav mus los ntawm RMF thiab lub rotor. Yog li ntawd, lub zog tangential ntawm lub rotor rau kev sib hloov rov qab los thiab pib los ntawm kev ua raws li RMF. Hauv qhov no, lub rotor tswj hwm qhov ceev tas li, uas tsawg dua qhov ceev ntawm RMF thiab qhov ceev synchronous. Ntawm no, qhov sib txawv ntawm qhov ceev ntawm RMF thiab lub rotor raug ntsuas hauv daim ntawv ntawm slip. Qhov zaus kawg ntawm lub rotor tuaj yeem tau txais los ntawm kev sib npaug ntawm slip thiab zaus muab khoom.
Kev Tsim Kho Lub Cev Muaj Zog Induction Rau Nas
Cov khoom uas yuav tsum tau siv rau kev tsim lub tshuab hluav taws xob squirrel cage induction yog stator, rotor, kiv cua, thiab bearings. Lub stator muaj cov winding peb theem uas sib nrug 120 degrees nrog lub tsev hlau thiab lub hauv paus. Yuav kom muab txoj kev tsis txaus siab rau cov dej ntws los ntawm AC tam sim no, lub winding raug ntsia rau ntawm lub hauv paus hlau laminated.
Lub rotor hloov cov zog hluav taws xob uas muab rau hauv cov khoom siv kho tshuab. Lub qhov, lub hauv paus, cov hlau tooj liab luv luv yog cov khoom ntawm lub rotor. Txhawm rau kom tsis txhob muaj hysteresis thiab eddy currents uas ua rau poob hluav taws xob, lub rotor yog laminated. Thiab kuv xaj kom tiv thaiv cogging, cov conductors yog skewed uas kuj pab muab qhov piv hloov pauv zoo.
Muaj ib lub kiv cua txuas rau tom qab ntawm lub rotor rau kev sib pauv cua sov pab tswj kom tsis txhob muaj qhov kub ntawm lub cev muaj zog. Rau qhov kev tig du, cov bearings tau muab rau hauv lub cev muaj zog.
