Cov Qauv thiab Txoj Cai Ua Haujlwm ntawm Asynchronous Tsav Tsheb

Rau cov neeg uas xav paub txog kev tsim hluav taws xob lossis cov tshuab kev lag luam, kev nkag siab txog cov qauv thiab cov ntsiab cai ua haujlwm ntawm cov asynchronous motors yog qhov tseem ceeb. Asynchronous motors, tseem hu ua induction motors, yog siv dav hauv ntau yam kev siv vim lawv tsim yooj yim thiab kev ua haujlwm txhim khu kev qha.

Cov qauv ntawm lub cev muaj zog asynchronous muaj ob ntu tseem ceeb: lub stator thiab lub rotor. Lub stator yog qhov ruaj khov ntawm lub cev muaj zog thiab muaj cov hlau tseem ceeb, stator windings thiab casing. Lub hauv paus feem ntau yog ua los ntawm cov hlau laminated los txo qhov poob zog, thiab cov stator windings txuas nrog lub zog sab nraud. Lub rotor, ntawm qhov tod tes, yog qhov tig ntawm lub cev muaj zog thiab muaj cov hlau tseem ceeb cylindrical thiab cov pas nrig lossis coils conductive. Lub rotor tsis txuas ncaj qha rau lub zog sab nraud, yog li nws hu ua lub cev muaj zog asynchronous.

Lub hauv paus ntsiab lus ua haujlwm ntawm ib qholub cev muaj zog asynchronousyog raws li lub zog sib nqus uas tig los ntawm lub stator uas ua rau muaj hluav taws xob hauv lub rotor. Thaum lub zog hloov pauv raug siv rau ntawm stator windings, lub zog sib nqus tig tau tsim tawm. Lub zog sib nqus tig no ua rau muaj hluav taws xob hauv cov conductors rotor, uas ua rau muaj lub zog sib nqus hauv lub rotor. Kev sib cuam tshuam ntawm lub zog sib nqus ntawm stator thiab rotor tsim lub zog torque, ua rau lub rotor tig.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov asynchronous motors yog lawv lub peev xwm ua haujlwm ntawm qhov ceev me ntsis dua li qhov ceev synchronous, yog li ntawd lub npe "asynchronous". Qhov sib txawv ntawm qhov ceev no, hu ua slip, tso cai rau lub cev muaj zog los tsim torque thiab tig los ntawm qhov nres. Asynchronous motors feem ntau siv rau hauv cov ntawv thov uas xav tau kev tswj hwm qhov ceev sib txawv, xws li cov kab ke conveyor, twj tso kua mis thiab kiv cua.

Hauv ntej, cov qauv thiab txoj cai ua haujlwm ntawm cov asynchronous motors yog cov ntsiab lus tseem ceeb hauv kev tsim hluav taws xob. Kev nkag siab txog seb stator thiab rotor cuam tshuam li cas los tsim kev txav mus los yog qhov tseem ceeb rau kev tsim thiab kev ua haujlwm ntawm cov asynchronous motors hauv ntau yam kev lag luam thiab kev lag luam.
