Nyob rau hauv cov txheej txheem ntawm kev tsim hluav taws xob, thaum lub tshuab hluav taws xob tig 360 degrees, tus kws tshaj lij hluav taws xob yuav ntsib qhov teeb meem ntawm cov xaim winding, lub sijhawm no, nws xav tau lub tshuab hluav taws xob sib txuas, feem ntau hu ua lub nplhaib hluav taws xob xaim hluav taws xob, xa hluav taws xob thiab teeb liab ntawm qhov kev sib txuas rotary.
Hauv lwm lo lus, kev ua haujlwm ntawm lub nplhaib ntiv nplhaib yog cov khoom siv hluav taws xob lub luag haujlwm rau kev sib txuas lus thiab kev sib kis ntawm lub zog thiab cov teeb liab rau lub cev rotating. Thiab raws li cov xov xwm sib txawv, cov hlua khi kuj tau muab faib ua cov hlua hluav taws xob, cov kua nplaum nplaum, cov nplhaib du, thiab lwm yam, uas tuaj yeem raug hu ua "rotary txuas" lossis "rotary txuas".
Lub hauv paus ntsiab lus ntawm kev ua haujlwm electromechanical ntawm cov hlua khi
Slip rings feem ntau yog ntsia rau hauv nruab nrab ntawm kev sib hloov ntawm cov khoom siv, thiab feem ntau yog tsim los ntawm ob ntu: tig thiab nyob ruaj ruaj. Lub rotating ib feem yog hu ua "rotor" thaum nws txuas mus rau lub rotating qauv ntawm lub ntaus ntawv thiab rotates nrog nws, thiab lub zog qhov chaw ntawm qhov chaw nyob ruaj ruaj uas txuas cov qauv ruaj ntawm lub cuab yeej hu ua "stator". Lub ntsiab sib txawv ntawm lub nplhaib nplhaib induction motors yog cov qauv rotor thiab hom kev ua haujlwm.
Nws tuaj yeem hais tau tias daim ntawv thov ntawm lub nplhaib ntiv nplhaib yog qhov dav heev, thiab nyob rau hauv high-end teb ntawm cov khoom siv niaj hnub no, muaj ntau yam kev xav tau rau cov txheeb ze txav xws li kiv puag ncig thiab kev sib hloov kom xa cov xov xwm sib txawv (tsis muaj zog tam sim no, teeb liab kho qhov muag. , huab cua siab, dej siab, thiab lwm yam) kom ntseeg tau tias cov khoom siv hluav taws xob ua haujlwm ib txwm muaj thaum lub zog tig. Piv txwv li, lub nplhaib ntiv nplhaib yog cov khoom siv tseem ceeb hauv cov khoom siv kho mob, cov khoom siv lom zem, cov khoom siv, cov koob yees duab ntse, lub qhov rooj thiab lwm yam khoom siv, nrog rau cov khoom siv dav hlau tsis zoo, cov khoom siv sib txuas lus radar, cov cuab yeej ua haujlwm tsis siv neeg, cov khoom siv smelting, cov khoom siv cable, Crystal furnaces, robots, thiab lwm yam.
