Lub hauv paus rau phau ntawv
Nyob rau hauv lub roar ntawm Chav ntawm London ntiaj teb expro nyob rau hauv lub xyoo pua puv 19, tib neeg yuav tsis muaj kev xav tias lub tshuab hluav taws xob hloov kho kom tiav hloov txoj kev uas tib neeg tau txais lub hwj chim. Los ntawm micro-kev co lub zog ntawm cov khoom siv hauv tsev ntse, los ntawm cov khoom siv hluav taws xob nrawm, tau ua lub zog ntawm lub zog ntawm lub zog, tau dhau los ua lub siab "lub siab ntawm kev vam meej. Kab lus no yuav txhawj txog qhov kev tsim tawm no uas tau hloov lub ntiaj teb.
1. Ib xyoo pua ntawm kev hloov pauv
Xyoo 1821, cov qauv ntawm Unpolar tsav ua los ntawm FareDay tsuas yog cia cov hlau kom tig ncig cov mercury ua pas dej. Qhov no zoo li yooj yim sim muaj ePOCH-kev tseem ceeb. Tom qab Tesla tau tsim ACTUCT lub cev muaj zog xyoo 1888, cov ntaub ntawv siv ntawm cov motors nrawm:
DC tsav(1890s): Nruam kev sib hloov yog ua tiav los ntawm cov txhuam txhuam, thiab nws tseem muaj dav siv hauv cov tsheb hluav taws xob
Asynchronous tsav (1910s): cov qauv yooj yim, tus nqi qis, nyob 60% ntawm kev lag luam muaj zog
Magnet Magnet Synchronous Tsav (1980
Txhuam tsis xeb(21st xyoo pua): Lub Chaw Haujlwm Hauv Hluav Taws Xob Hluav Taws Xob Ua Rau Lub Neej Kev Pab Cuam Tshuam
Ii. Kev muaj lub cev ntawm lub cev ntawm txoj cai ua hauj lwm
Lub ntsiab lus ntawm lub cev muaj zog yog lub zog hluav taws xob-tshuab hluav taws xob hloov pauv, thiab cov tub ntxhais nyob hauv kev sib cuam tshuam ntawm daim teb sib nqus thiab tam sim no:
Kev tsim kho ntawm stator sib nqus sib nraus teb: AC yog kis mus rau hauv peb-theem winding los ua ib qho kev sib nqus khiav (synchronous ceev n {1}} f / p)
Rotor teb mechanism:
Asynchronous tsav: tus rotor Campor txiav cov kab sib nqus flux los tsim cov tenduced tam sim no → tam sim no nqa cov neeg ua si yog raug rau Lorentz quab yuam
Synchronous lub cev muaj zog: lub tas mus li hlau nplaum ncej thiab lub rotating sib nqus teb yog Angianly xauv
Dynamic Tshuav Sib npaug: t =} kφicosθ (Quantitative Kev sib raug zoo ntawm Torque, Flux thiab Tam Sim No)
